- When using this tungsten carbide drill bits for the first time, try to cut at 90% of the cutting speed or 85% of the feed speed according to the above data, and then increase the cutting speed and feed rate one by one after the cutting condition is stable
- This standard cutting condition is applicable to water-soluble cutting fluid
- When installing the tool, please use a clean chuck with defects removed, and control the radial runout of the drill bit within 0.02mm
- The cutting conditions in this table are applicable to situations with hole depth below 5D
Notice:
- When drilling steel parts, please ensure sufficient cooling capacity and use metal cutting fluid.
- Good drill pipe rigidity and guide rail clearance can improve drilling accuracy and bit life.
- Please ensure the flatness and cleanness between the magnetic base and the workpiece.
- When drilling thin plates, reinforce the workpieces. When drilling large workpieces, ensure that the workpieces are stable.
- At the beginning and end of drilling, the feed rate shall be reduced by 1/3.
- For materials with large amount of fine powder during drilling, such as cast iron, cast copper, etc., compressed air can be used instead of coolant to help remove chips.
- Please remove the iron scraps wrapped on the drill body in time to ensure smooth chip removal.
Applications:
Our tungsten carbide drill bits could to be processed Alloy steel, Tool steel, carbon steel, stainless steel, Cast iron and Titanium alloy. Working material as following:
FAQ
Q1. Excessive aperture
Reasons: 1. The cemented carbide drill is not well clamped, and the runout of the spindle itself is too large
2. Asymmetrical sharp angle, excessive blade height difference, eccentric cross blade
Solution: 1. select high-quality tool handle and fixture, calibrate the spindle, and carefully measure and adjust each time the drill is clamped
2. Re sharpen and correct, and check the accuracy after sharpening
Q2. Poor consistency of aperture
Reasons: 1. Asymmetrical sharp angle, too large difference in blade height, eccentric transverse edge, and too much wear on edge surface
2. The cemented carbide drill bit is not properly clamped, the runout of the spindle itself is too large, and the workpiece is not firmly clamped
3. Excessive feed speed
4. Insufficient cutting fluid supply
Solution: 1. Re sharpen the drill and check the accuracy after sharpening
2. Select a good tool handle and fixture, calibrate the spindle, and carefully measure and adjust each time the drill is clamped
3. Reduce the feed speed of cemented carbide drill
4. Change the cutting fluid supply method and increase the flow).
Q3. Poor hole straightness and verticality
Reasons: 1. Excessive tool wear
2. Asymmetrical sharp angle, excessive blade height difference, eccentric cross blade
3. Insufficient rigidity
4. Uneven cutting plane
Solution: 1. Re sharpen
2. Re sharpen and correct, and check the accuracy after sharpening
3. Improve the rigidity of machine tools, jigs, cemented carbide drills, etc
4. Check the levelness of the pre machined surface
Q4. Poor hole location and poor consistency of center distance
Reasons: 1. The drill bit is not properly clamped, and the spindle itself has excessive runout
2. Deviation during cutting
3. Machine tool accuracy loss
4. The centering effect of cemented carbide bit is poor, and the cross edge is eccentric
Solution: 1. select a good tool handle and fixture, calibrate the spindle, and carefully measure and adjust each time the drill is clamped
2. Improve the rigidity of the cutter and machine tool, and the rigidity of the workpiece and fixture. Use the drill type with good cutting performance, and check the levelness of the cutting surface
3. Check the accuracy of the machine tool
4. Re sharpen the carbide bit, and check the accuracy after sharpening
