The drill bit has a strong impact force when it is changed, so the drill bit device can adapt to any type of formation. The drilling speed of CNC drills has been greatly developed. How to use CNC drills correctly mainly includes the following aspects: Tip runout 1. Select the correct machine tool. CNC drills can be applied to CNC machine tools. Machining centers have high power and good steel performance, and the knife TIR should be guaranteed to be <0.02. The rocker drill, universal milling and other machine tools due to the power is small, the spindle accuracy is poor, easy to lead to the early collapse of the CNC drill bit, should try to avoid. 2. Choose the right hilt, spring clip
The drill bit has a strong impact force when it is changed, so the drill bit device can adapt to any type of formation. The drilling speed of the numerical control drill bit has been greatly developed, how to use it correctly.nc drill bit, mainly including the following aspects:
1. Select the correct machine tool. CNC drill bits can be applied to CNC machine tools, machining centers and other machine tools with high power and good rigidity, and ensure that the tip runout TIR<0.02. The rocker drill, universal milling and other machine tools due to the power is small, the spindle accuracy is poor, easy to lead to the early collapse of the CNC drill bit, should try to avoid.
2. Select the correct tool holder, spring chuck, side pressure tool holder, hydraulic tool holder, thermal expansion tool holder, etc. can be used. However, due to insufficient clamping force of quick-change drill chuck, it is easy to cause the drill bit to slip and fail. Use should be prevented.
3. After the drill bit goes down to the bottom of the hole, it should be lightly pressed and rotated slowly. After drilling 0.10-0.20m with large displacement, it can be converted to normal drilling. In the drilling process, if the footage is accelerated, the drilling pressure and displacement should be increased in time, and if the footage is slow, the drilling pressure and displacement should be adjusted in time, so that the maximum aging of the numerical control bit in drilling can be mastered and controlled at any time.
