High Machining Precision Of Cemented Carbide Bit
Oct 19, 2017



Cemented carbide bit material is mainly fine particles of cemented carbide, although a whole cemented carbide can only be milled about 10 times, however, in order to prolong its service life manufacturers have carried out the coating treatment, the function of the self centering also makes the whole cemented carbide bit more practical. Ultra Coarse Carbide Drilling Insert The machining aperture range of carbide indexable inserts is very wide and practical. Welded carbide bits work with high accuracy and most materials can be drilled. The replaceable cemented carbide crown bit not only has the function of self centering, but also has high precision with the welding type carbide bit.

Correct use of cemented carbide drills

1. Because cemented carbide is very valuable, the correct use of drill bits, Ultra Coarse Carbide Drilling Insert to make the most of the best, is the responsibility of every mechanical processing practitioner. The correct use of carbide drill bit, mainly include the following aspects:

Carbide bit can be used in CNC machine tools, machining centers, such as large power, rigid good machine tools, and should ensure that the tip beat tir<0.02. and rocker drill, universal milling machine because of the small power, spindle accuracy is poor, easy to lead to the early collapse of cemented carbide bit, Ultra Coarse Carbide Drilling Insert should be avoided as far as possible.

2. Select the correct shank spring chuck, side pressure holder, hydraulic toolholder, hot-rise hilt can be used, but because the quick change drilling Chuck clamping force is not easy to cause the bit slipping and failure, should be avoided.

(2) The inner cold bit should pay attention to the pressure and flow, Ultra Coarse Carbide Drilling Insert and should prevent the cooling liquid leakage to affect the cooling effect.

3. Correct cooling

(1) Cold should pay attention to the cooling direction combination, form up and down echelon configuration, and minimize the angle with the tool.

4. Correct drilling Process

(1) When the inclination of the drilling surface is >8-10°, it is not drilled. When <8-10°, Ultra Coarse Carbide Drilling Insert the feed should be reduced to normal 1/2-1/3;

(2) When the drilling surface inclination >5°, the feed should be reduced to the normal 1/2-1/3;

Advantages of cemented carbide drills:

1. Can be suitable for more complex material drilling, can choose a higher cutting speed.

2. Selected alloy bit special high-performance alloy blade, effectively reduce the knife collapse, maintain good wear resistance.

3. Multi-layer geometry cutting end blade, improve excretion performance, maintain small cutting resistance.

4. In addition to the common right angle handle, with a variety of handle type, Ultra Coarse Carbide Drilling Insert Ultra Coarse Carbide Drilling Insert suitable for a variety of drilling rig, drilling machine.
