CNC Drilling Machine Can Increase The Use Of Drill Bits

- Oct 30, 2017-

1. Drill should be installed in a special box, CNC Drilling Machine to avoid vibration collide with each other.

2. When used, remove the drill from the box should be installed in the spring chuck of the spindle or automatically replace the drill tool library. CNC Drilling Machine Run out immediately into the box.

3. Measuring the diameter of the drill using a tool microscope and other non-contact measuring instruments, to avoid cutting edge and mechanical measuring instrument contact and was bumped.

4. Some CNC drilling machine using the positioning ring Some CNC drilling machine does not use the positioning ring, such as the use of positioning ring when the installation of the depth of positioning must be accurate,CNC Drilling Machine if not use the positioning ring to drill to the spindle on the extension to adjust Consistent, multi-spindle drilling machine to pay attention to this point, CNC Drilling Machine so that the depth of each spindle to be consistent. If the inconsistency is likely to drill the drill bit to the table or can not drill through the circuit board to cause scrapping.

5. Usually 40 times the stereoscopic microscope can be used to check the drill bit cutting edge wear.

6. Always check the concentricity of the spindle and spring chuck and the clamping force of the spring chuck. If the concentricity is not good, it will cause the drill and the hole of the small diameter to be broken and the aperture is large. The clamping force will cause the actual speed and Set the speed does not meet, CNC Drilling Machine chuck and drill between the slippery.

7. Set the handle bit in the spring chuck on the length of the drill handle diameter of 4 to 5 times to clamp.

8. Always check the spindle presser foot. CNC Drilling Machine Press the foot contact surface to the level and the vertical axis can not shake, to prevent drilling holes and drill holes.

9. The substrate stack includes upper and lower pads to be positioned in a slot-on-slot positioning system on the drill table. The use of adhesive tape to prevent the drill bit drilled on the tape so that the drill sticks to the chip, causing the chip to be difficult and broken.

10. Order the manufacturer's drill, into the factory inspection to check whether the 4% meet the requirements. CNC Drilling Machine And 100% with 10 to 15 times the microscope to check the gap, scratches and cracks.

11. Drill timely grinding, can increase the number of drill bit and the number of grinding, to extend the life of the drill bit, reduce production costs and costs. Usually measured with a tool microscope, within the length of the two main cutting edge, the depth of wear should be less than 0.2mm. CNC Drilling Machine Grinding to wear 0.25mm. Ordinary fixed drill bit can be re-ground 3 times, shovel head (undercut) drill can be re-grinding 2 times. Overtaking too much of its drilling quality and accuracy will decline, CNC Drilling Machine will cause the finished product board scrap. Excessive turning effect is counterproductive.

12. When the wear due to wear and its wear diameter compared with the original reduced by 2%, the drill bit scrapped.
