Advantages and classification of drill bit application

1 bit is a kind of rotation and head end cutting ability of tools with carbon steel or high speed steel SKH2 SK corp, commonly SKH3 materials such as the milling or rolled again after quenching, tempering heat treatment after grinding and become, used for metal or other materials on the drilling, a wide scope of its use, can be applied to drilling machine, lathe, milling machine, drill tools such as machine use.  

 

Woodworking drill can be divided into: woodworking twist drill, brace drill, hole opener, can do transverse cutting multi-function drill, flat drill and so on

Metalworking (aluminum, steel, pig iron, wrought iron, alloy parts) drill and can be divided into: metal twist drill, metal reamer, pagoda drill, stainless steel materials and it has a special set of drill opening appliances

Masonry bit (glass, ceramic tile, marble) can be divided into: triangle drill impact drill sample impact drill glass ceramic tile opener


2. Type of drill bit  

A. Classification by structure  

(1) Integral bit: the drill top, the drill body and the drill shank are made of the same material as a whole. (2) End welding bit, the top bit is welded by carbide  

B. In accordance with the drilling hole classification (1). Straight shank drill: drill diameter w13.0mm below, all use straight shank (2) taper shank drill: drill shank taper shape, the general taper are Morse taper  

C. By use  

(1) center drill bit: generally used for drilling before hitting the center point, the front cone has 60°, 75°90, etc., lathe operation in order to use the tail seat support, holding should use 60° center drill and lathe tail seat center 60°  

(2) Twist bit: the most widely used bit for industrial manufacturing, we generally use twist bit 

(3) superhard bit: the drill body before or all made of superhard alloy cutting material used for drilling materials processing

 (4) oil hole bit:  There are two holes in the drill body, through which the cutting agent reaches the cutting tool part to take away heat and chips. The drill bit is usually used for rotating, while the drill bit is stationary. 

(5) The deep-hole drill bit was first used for drilling the barrel and stone casing, also known as the barrel drill bit.  The deep hole drill bit is a groove type that excizes more than a quarter of a round pipe to produce cutting chip removal 

(⑥).  Drill reamer: in order to mass production, the front end is the drill, the back end is the reamer, the diameter of the drill and the diameter of the reamer is only different from the margin of reaming, there are also mixed use of drill in screw tapping, so it is also called the mixed drill

 (7).  Tapered bit: When machining the feed opening of a die, a tapered 

(8) cylindrical bit can be used. We call this a counterhead milling cutter. This bit has a small diameter portion at the front end called a tapered

 (9) bit:  For drilling conical holes, which have a front end Angle of 90°, 60°, etc., the chamfering cutter we use is a kind of conical hole drill bit 

(10) triangle bit: a drill bit used by electric drills, the drill shank is made into a triangular face, so that the collet can hold the bit firmly

​maintaining​​

1.Better rigidity of drill pipe and clearance of guide rail can improve the precision of drilling and the life of drill bit

2.Please make sure that the magnetic seat is smooth and clean between the workpiece.

3.It is necessary to strengthen the workpiece when drilling thin plate. 4.When drilling large workpiece, please ensure the stability of the workpiece.

5. When drilling begins and ends, the feed should be reduced by 1/3.

6.Pictures of a large number of fine powder when drilling materials, such as cast iron, copper, can not use coolant, and the use of compressed air to help chip removal.

7. Please remove the iron filings wrapped around the drill body in time to ensure smooth chip removal.

​The safety rules​

⒈ During operation, please wear good work clothes, safety glasses, safety hats, etc. Please do not wear loose clothes and gauze gloves to avoid danger.

⒉ In order to prevent the iron filings will scratch the hand, when drilling, please use iron hook to remove iron filings.

Please check whether the drill bit has scars before use. If there are scars, please do not use it.

4. If the drill bit is stuck, please turn off the motor immediately.

When replacing or disassembling drill bits, it shall ensure that the power supply of the equipment is disconnected.

6. When the drill is rotating, please don't touch it with your hands in case of danger.

usage mode

1.Drill bits should be installed in special packaging boxes to avoid vibration collision.

2.When used, take out the drill from the box should be installed into the spindle spring chuck or automatic replacement of the drill tool store. Put it back in the box.

3.A tool microscope and other non-contact measuring instruments should be used to measure the diameter of the drill bit, so as to avoid the cutting edge being bruised by contacting with the mechanical measuring instrument.

4.It is certain that some CNC drilling machine using positioning ring some CNC drilling machine does not use positioning ring, such as the use of fixed ring when the depth of the installation positioning must be accurate, such as not using the positioning ring the drill mounted to the spindle length to adjust consistent, more spindle drilling machine should pay attention to this point, to make each spindle drilling depth should be consistent. If inconsistent, it may cause the drill to drill to the table or unable to drill through the circuit board, resulting in obsolescence.

5. At ordinary times, 40 times stereoscopic microscope can be used to inspect the wear and tear of the cutting edge of drill bit.

6. Often check spindle and spring collet concentricity and spring collet clamping force, concentricity is not good will cause small diameter drill break and large aperture, clamping force is not good will cause the actual speed and set speed does not conform to, between the collet and drill slip.

7. The clamping length of the bit on the spring chuck is 4 to 5 times the diameter of the drill shank.

8. Check the spindle press foot often. Press foot contact surface should be horizontal and vertical with the main shaft can not shake, to prevent drilling and offset hole.

Its dust suction efficiency is good. Its suction air can lower the bit temperature and take away dust to reduce friction and generate high temperature.

The underlying layer, including the upper and lower backing plates, has been firmly positioned and put flat in the one-hole and one-slot positioning system on the work table of the drill press. When using adhesive tape, it is necessary to prevent the bit from sticking to the tape and cutting chips, resulting in chip removal difficulty and drilling break.

Learn about ordering manufacturer's drill bits. Learn if 4% of them are in conformity with factory requirements during incoming inspection. And 100% with 10 ~ 15 times the microscope to examine its notch, scratch and crack.

2, Fetch out, when the wear diameter decreases 2% compared with the original due to wear, the drill bit is discarded.

⒕ bit parameter setting in the general case, manufacturers provide a copy of the plant in the production of bit drilling speed and the speed parameter list, this parameter is only a reference, the actual technology personnel through actual use to draw even a bit conforms to the actual situation of speed and speed parameters, usually have difference between the actual parameters and the parameters of the reference but not too much difference.

⒖ when the bit is grinding, the two main cutting edges of the twist drill should be ground symmetrically as far as possible, so that the radial forces of the two main cutting edges cancel each other, in order to prevent the bit deviation and the expansion of the aperture.
