A Guide to Drill | Accusharp Drills | Features and It’s Application

Drilling is the most frequent method for making machined holes since it is easy, rapid and cost-effective.

One of the most difficult machining procedures is drilling. The combined cutting and extrusion of Metal at the chisel edge in the centre of the drill is the main feature that sets it apart from other Machining operations. The feeding motion’s high thrust force extrudes metal under the chisel edge first.Then, when a negative rake angle tool is used, it tends to shear.

 

The drilling machine settings indicate several key characteristics of this hole-making process.The Drill radius is most directly related to the depth of cut, which is a crucial dimension in other Cutting operations. The length of the drill lip, which is dependent on the point angle as well as the Drill size, is equal to the un-deformed chip width.The feed per lip is a more fundamental metric. It’s half the feed per revolution for a standard two-flute drill. Depending on the tip angle, the Un-deformed chip thickness varies from the feed per lip.

 

For every given operation, the spindle speed remains constant; however the cutting speed varies along the cutting edge. Normally, cutting speed is calculated based on the outside diameter. The cutting speed is zero in the centre of the chisel edge and proportional to the radius of any point on the lip. A key feature of drills is the variation in cutting speed along the cutting edges.

When the drill engages the workpiece, it remains in contact with it until it breaks through the Bottom of the part or is withdrawn from the hole. Drilling is similar to turning but not the same as Milling in this regard. Continuous cutting implies that constant forces and temperatures can be Expected soon after the drill makes contact with the work piece.

 

Drill:
A drill is a hole-making tool with an end-cutting tool. It has one or more cutting edges, as well as flutes that allow fluids and chips to pass through. A shank, body, and point make up the drill. Faster cutting speeds, longer tool life, greater positional and dimensional precision, and improved surface polish are all advantages of carbide drills. Accusharp Cutting Tools Manufacturers provides Carbide Drills of the highest quality, known for their outstanding performance, maximum torque capacity, and longer service life.

Accusharp cutting Tools Manufacturers developed cutting tools to provide exceptional accuracy while improving productivity and lowering costs.

 

Drill Parameters:

  • Shank :
    The shank of a drill is the part that is held and driven. It could be either straight or tapered.

  • Body :
    The flutes are included in the drill’s body, which span from the shank to the point. The body of drill is partially ground away during the sharpening process.

  • Point :
    The drill’s cutting end is the point.

  • Flutes :
    Flutes are grooves carved or created into the drill’s body to allow fluids and chips to reach the tipand the workpiece surface.Straight flutes are occasionally employed, but they are usually helical.

  • Land :
    After the flutes are cut, the land is the remaining outside of the drill body. To give clearance, the land is chopped back from the outside drill diameter.

  • Margin :
    The margin is a small area of land that has not been cleared. It keeps the entire drill diameter.

  • Lips :
    The lips are the drill’s principal cutting edges. They stretch from the drill’s chisel point to the drill’ periphery.

  • Web :
    The web, which connects the lands, is the core section of the drill body.

  • Chisel edge :
    The chisel edge is the edge ground on the tool point along the web. It joins the cutting lips together.

  • Axis :
    The drill’s axis is also the tool’s centerline.It is perpendicular to the diameter and travels through the web.

  • Length :
    The axial length of a drill is mentioned with its outside diameter when the drill size is specified.
    In addition, shank, flute, and neck lengths are frequently utilized.

  • Body Diameter Clearance :
    The body diameter clearance is the height of the step from the margin to the land.

  • Web Thickness :
    The smallest dimension across the web is the web thickness.Unless otherwise stated; it is
    Measured at the point. As you move up the body away from the point, the web thickness will
    Often rise and you may need to grind it down during sharpening to minimize the size of chisel edge. This is referred to as “web thinning”.

  • Helix Angle :
    The helix angle is the angle formed by the leading edge of the land and the drill axis. Drills with varied helix angles are offered to meet a variety of operational needs.

  • Point Angle :
    The point angle is the included angle between the drill lips. It varies depending on the substance of the work piece.

  • Lip Relief Angle :
    The lip relief angle corresponds to the common relief angles found on other tools. It is calculated at the outskirts.

  • Chisel edge Angle :
    As seen from the end of the drill, the chisel edge angle is the angle formed by the lip and the
    Chisel edge.

    Drilling operations that are related:

    Drilling encompasses a wide range of activities.Except for centering and spotfacing, which come
    Before drilling; the most of the procedures in the following list come after drilling. Drilling must be
    Used to create a hole, which must then be adjusted by one of the other processes.

    Reaming:
    A reamer is used to enlarge a previously drilled hole, to provide a higher tolerance and to improve the surface finish of the hole.

    Tapping:
    A tap is used to create internal threads in a hole that has already been bored.

    Counter boring:
    To allow a bolt head to be seated below the part surface, counterboring creates a bigger step in hole

    Countersinking:
    Countersinking is similar to counterboring, except the step is angled to allow flat-head screws to sit below the surface.

    Spotfacing:
    Spotfacing is a process that gives an item a flat, machined surface.

    Centering:
    Center drilling is used for accurately locating a hole to be drilled afterwards.

     

    Operating Conditions:
    It’s difficult to offer specific criteria for speeds and feeds because of the wide range of settings underwhich drills are utilized. For drilling a range of materials, drill manufacturers and a number of Reference texts provide recommendations for optimum speeds and feeds.

     

    Drilling Speed:
    Cutting speed is defined as the rate at which a point on a drill’s diameter travels in one minute. It’s measured in feet per minute on the surface (SFPM). Cutting speed is one of the most critical Criteria in determining how long a drill last. The will drill may chip or break if the cutting speed is too High a speed quickly dulls the cutting lips.

     

    Cutting speeds are determined by seven Factors:

    • The type of material being drilled. (The harder the material, the slower the cutting speed.)
    • The diameter and substance of the cutting tool. (The faster the cutting tool can manufacture the material, the tougher the material is.) The bigger the drill, the slower it has to spin.)
    • Cutting fluids can be used in a variety of ways, which allows for faster cutting.
    • The drill press’s sturdiness
    • The drilling quality of the hole.
    • The work environment’s rigidity.
    • The drilling quality of the hole.

    Before drilling a hole, each variable should be evaluated. Each variable is critical, but the work Material and cutting speed is the most critical.

     

    Drilling Feed:
    The optimal feed rate must be determined once the cutting speed has been determined for a certain work piece material and condition. Feed rates for drilling are chosen to enhance productivity while preserving chip control. In drilling operations, feed is measured in inches per revolution, or IPR which is the distance travelled by the drill in inches for each rotation.

Everything you need to know about Endmills| Basic beginners guide | Accusharp Endmills | Accusharp Cutting Tools

Due to progressive build up of chip load in up milling operation, heat emission is high. So, there exists a inclination of chip welding with the teeth. Inclination of chip welding is less in down milling but chip re-deposition on wrapped up surface happens as often as possible that debase quality of wrapped up surface.
In this operation, Burr is shaped as it were on unfinished surface ahead of the tool nourish, larger part of such burr is evacuated within the consequent passes. In this operation, Burr is shaped at on finished surface in inverse side of the tool feed. In this operation, burr is not evacuated consequently. This leads to debased cutting quality.
Other than making surface wrap up, rubbing amid engagement may result in undesirable work solidifying owing to critical heat emission. Chances of work solidifying are negligible with down milling operation.

 

 

 

In up milling operation, No backslash eliminator is required. In Down milling operation, Backslash eliminator is required, particularly in case the milling machine is older one.

Endmill is a cutting tool used for end milling operations. Endmills or Milling cutters utilized in CNC machines. CNC stands for Computerized Numerical Controlled.

Endmill tools are accessible in a wide variety of lengths, flutes, diameters, and types and are chosen for concurring to the material they are cutting and surface finish required for the product.

Endmill is a cutting tool used in various machines like milling and turning machines. They are utilized for Reaming, Slotting, Drilling, Contouring, and profiling as well. Their physical appearance is commonly confounded with a Drillbit but they are diverse in numerous ways. Drill bits cuts axially (in one direction) and the Endmills cutter can cut in axially and laterally (multiple directions). This comes in helpful with accuracy cutting

Endmill Tools is utilized in Machines Parts, sign making, plastic cutting, mold making, wood inscriptions, mold making, and circuit boards.

Flutes highlight grooves or valleys that are cut into the tool body. A better number of flutes increases the quality of the tool and decreases space or chip flow. Endmills with fewer flutes on the cutting edge will have more chip space, while endmills cutter with more flutes are going to be ready to be utilized on harder cutting materials.

 

Single Flute End mill designs are utilized for high-speed machining and high-volume material removal.

Two Flute End mill designs have the foremost amount of flute space. They permit for more chip carrying capacity and are utilized basically in slotting and pocketing nonferrous materials.

Three Flute End mill designs have the same flute space as two flutes, but also have a bigger cross-section for noteworthy quality. They are utilized for pocketing and slotting ferrous and nonferrous materials

Four/Multiple Flute Endmill designs permit quicker feed rates, but due to the reduced flute space, chip\moval may be an issue. They create a much better wrap-up than two and three flute tools. Perfect for peripheral and finish milling

 

End Cut Types:

  • Centre cutting tools have one or more cutting edges at the tip and are utilized in an assortment of applications including plunging, drilling, or ramping.
  • Non-centre cutting applications have confronted teeth allowing for the user to side (radial) cut from the outside surface. Utilized in applications where plunge cutting is not necessary.

 

End Mill Coating

Titanium Carbonitride COATING ON END MILL (TiCN) is harder and more wear-resistant than Titanium Nitride (TiN. It is commonly utilized on stainless steel, cast iron, and aluminum alloys. TiCN can give the capacity to run applications at higher shaft speeds. Utilize caution on nonferrous materials since of an inclination to rankle. Requires an increment of 75-100% in machining speed vs. uncoated tools.

 

Sizes:   Estimates extending from Ø 2mm to Ø 32mm

 

The raw material used:

These Endmills are made from Tungsten Carbide provided by worldwide brands. We have advanced facilities, machines, and process equipment for manufacturing these products.

Up Milling and Down Milling Operation.

Difference between Milling and Down Milling Operation.

Up Milling Down Milling
In up milling operation, Chip load on teeth (or uncut chip thickness) increments continuously from zero at the point of engagement to most extreme at the point of separation. In Down milling operation, Chip load on teeth (or uncut chip thickness) decreases continuously from a maximum at the point of engagement to zero at withdrawal.
In this operation, the Table turns against the direction of the table feed. In this operation, the Table turns along the direction of the table feed.
At the starting of engagement, teeth rub will lay or nourish marks on the machined surface. This makes strides surface wrap up. No such rubbing activity takes put and hence lay marks remain intact on the machined surface.
Here, the tooth encounter continuous loading as contact begins with zero chip load Here, tooth involvement affects loading as the tooth locks in abruptly with the most extreme chip load.
In up milling, horizontal axis milling machine, cutting drive in up processing mode is coordinated upward. Hence, it tends to lift the workpiece from the workable. Appropriately, unbending and costly installation is required for immovably mounting the workpiece. In down milling, operation mode, the cutting constrain is coordinated descending, and in this way, it tends to press the workpiece instead of lift-off. So cheaper installation can be utilized.
Thin workpiece tests, in case, machined utilizing up milling mode, may get misshaped due to upward cutting constrain. Chances of mutilation of thin workpiece tests are less with down milling mode on the off chance that legitimate support in the bottom is given
Due to progressive build-up of chip load in an up milling operation, heat emission is high. So, there exists an inclination of chip welding with the teeth. The inclination of chip welding is less in down milling but chip re-deposition on wrapped up surface happens as often as possible that debase the quality of the wrapped up surface.
In this operation, Burr is shaped as it were on an unfinished surface ahead of the tool nourish, the larger part of such burr is evacuated within the consequent passes. In this operation, Burr is shaped on the finished surface on the inverse side of the tool feed. In this operation, the burr is not evacuated consequently. This leads to debased cutting quality.
Other than making surface wrap up, rubbing amid engagement may result in undesirable work solidifying owing to critical heat emission. Chances of work solidifying are negligible with a down milling operation.
In up milling operation, No backslash eliminator is required. In Down milling operation, a Backslash eliminator is required, particularly in case the milling machine is older one.

Reamer | Solid Carbide Reamer| Accusharp Reamer tools to fulfil your Industrial needs.

Reaming, drilling and boring are three common forms performed by any manufacturing company. All three forms include, to a few degrees making a new hole or modifying an existing hole in a workpiece. Whereas most individuals are commonplace with penetrating. Even though, numerous are new with boring and reaming.

Reaming is a cutting process that requires the use of a rotational cutting tool to make smooth insides dividers in an existing hole in a workpiece. The rotary cutting tool utilized in reaming is known as a reamer. Like, drill bits, reamers also evacuate material from the workpiece on which they are utilized. However, the reamer removes less material than drill bits. The main purpose of reaming is to create smooth walls in an existing hole. Manufacturing companies perform reaming operations by using a milling machine or drill press.

Reaming is a part of the precision machining process or finishing process. Holes are mainly reamed in case of special requirements around surface quality, roundness, cylindricity, and diameter tolerance.

Acuusharp reamer is a sort of revolving cutting tool used for surface wrapping up operation at the side of a controlled endure hole. Ordinary reamer geometry comprises parallel/straight or helical cutting edges along the length of the around and hollow body. 

All cutting edges are ground at a slight point and with a slight undetermined underneath the cutting edge. This guarantees along life for the reamer and a predominant wrap-up to the hole. Having HSN2 and Alcorna coating for great surface wrap-up and less wear of the instrument. Utilizing high parameters with the best design, available in a straight, helical plan with strong and TCH form.

What is Gun Drill Tool? | Deep hole Drilling | Gun drill manufacturers from pune | Accusharp Cutting Tools.

Deep-Hole Drill was initially invented for ‘Gun-Driiling’application in Europe during the second world war, and since then it’s popular as Gun-Drill. However, last 75 year, its applications are extended automobile and other engineering metal cutting industries for Deep-Hole Drilling. still, these Deep Hole Drills are yet popularly called ‘Gun-Drills’, even if other used for other applications. It is a thin cutting tool to produce hole in a metal at high depth diameter ratio

 

What is Gun Drill Tool?

For exceptionally precise deep holes in metal work pieces, Gun drill tool are perishable tooling components that enter coolant through the machine spindle and midsection of the tool, and exhaust chips in a groove along the length of the tool.

A sophisticated grinding equipment, or CNC cutter grinder, can be used to sharpen gun drill tool numerous times to extend their life. For form tool operations, customised forms can also be machined into gun drill tooling tips.

By using high pressure coolant for clean chip exhaust, the gun drilling method can drill deep holes beyond what is achievable with conventional gear and tooling such as twist drills, even at extreme depths.

Gun drilling was first established for the production of gun barrels, when straightness and barrel durability were both required for proper operation. For maximum performance and utilisation on current, specialised gear, the gun drilling technique and tooling have been optimised. Gun drilling is still widely used in the firearms industry. Diesel fuel components, medical tooling, plastic injection moulds, and other industries are among the others.

 

Accusharp Cutting tools have entered into this new segment of Round tools For Deep Hole Drilling applications. The applications are for deep hole drilling On Crankshaft, Engine-Blocks, turbo-Blades, Paper Rollers, Machine Tools, and Fixturing etc. we are the leading Gun drill tool manufacturers from pune.

 

The main purpose of a gun drill tool is to drill consistent holes in one pass. The machine work is therefore fairly simple. The entire machine consists of the gun drill itself, the machine, the coolant supply system, the work holding fixture, and the part handling equipment.

Standard geometry for Gun Drill has been shown herewith. However, it may change according to its applications for different work materials and machining parameters. Moreover any change, in cutting edge geometry will have an effect on bore surface finish, geometrical accuracy, drill centring, chip shape, chip removal, process reliability and useful life of the Drills etc.

 

Deep Hole Drilling 

Gun drilling is a deep hole drilling technique that produces holes in metal with large depth-to-diameter ratios by using a long, thin cutting instrument. Gun drilling works on diameters ranging from 3.00mm to 32 mm.

The distinctive head shape of a gun drill tool distinguishes it from a normal twist drill; a standard gun drill has a single effective cutting edge that removes chips as it advances into a metal work piece.

Gun drilling was first established for the production of gun barrels, when straightness and barrel durability were both required for proper operation. For maximum performance and utilisation on current, specialised gear, the gun drilling technique and tooling have been optimised. Deep hole drilling utilized in a variety of industries. Gun drilling is still widely used in the firearms industry. Diesel fuel components, medical tooling, plastic injection moulds, and other industries are among the others.

By using high pressure coolant for clean chip exhaust, the gun drilling method can drill deep holes beyond what is achievable with conventional gear and tooling such as twist drills, even at extreme depths.

Gun drilling can be done on standard CNC machines, but only to a limited extent. To achieve the best productivity and process dependability, more often than not, specialized equipment is required.

Accusharp cutting tools provide perfect deep hole drilling solutions for customer problem.

 

ACCUSHARP Gun drills are straight fluted drills which allow cutting fluid (either compressed air or a suitable liquid) to be injected through the drill’s hollow body to the cutting face. ACCUSHARP drills used for deep drilling—a depth-to-diameter ratio of 300:1 or more is possible. Gun barrels are the obvious example; hence the name. 

Other uses include moldmaking, diemaking, and the manufacture of combustion engine parts such as crankcase, cylinder head, and woodwind musical instruments, such as uilleann pipes, as gun drills can drill long straight holes in metal, wood, and some plastics. 

The coolant provides lubrication and cooling to the cutting edges and removes the swarf or chips from the hole. Modern gun drills use carbide tips to prolong life and reduce total cost when compared with steel tips. Speed of drilling depends on the material being drilled, rotational speed, and the drill diameter.

Gun drill tool are easily consolidated with CNC machining centres, lathes and milling machines for a reasonably small investment, which makes these tools economical for a small or large business with varying production requirements. 

Our standard grinding geometry can take care virtually of all drilling operations successfully. However, for any special working conditions like deep hole drilling long chipping material that is difficult to machine. we design and manufacture  Gun-Drills with special geometries accordingly.

Our Present range of Gun drill tool is of Diameters between 4 and 30 mm, having length up to 1000 mm.
