A Glass Hole Saw Drill Bit is a machine equipment used for professional drilling of glass. Glass drill bits are different from ordinary drill bits. There are many types of drill bits. Glass drill bits are highly specialized and have high hardness, making them suitable for drilling glass. How should a glass drill bit be used? Glass drill bits, like ordinary drill bits, require the use of a drilling machine to operate. When using glass drill bits, it is necessary to choose according to different specifications, as there are many specifications for glass drill bits. Different sizes of glass drilling require the use of different glass drill bits. Let's take a look at how to use a glass drill bit. 1. The drill bit should be packed in a specially designed packaging box to avoid vibration and collision with each other. When using, remove the drill bit from the packaging box and immediately install it into the spring clamp of the spindle or the tool library for automatic replacement of the drill bit. Immediately return to the packaging box after use. 3. To measure the diameter of the drill bit, non-contact measuring instruments such as a tool microscope should be used to avoid damage caused by contact between the cutting edge and the mechanical measuring instrument. 4. Some CNC drilling machines use positioning rings, and some CNC drilling machines do not use positioning rings. If a positioning ring is used, the depth positioning during installation must be accurate. If a positioning ring is not used, the elongation of the drill bit installed on the spindle should be adjusted uniformly. Multi spindle drilling machines should pay more attention to this, ensuring that the drilling depth of each spindle is consistent. If inconsistent, it may cause the drill bit to drill onto the table or fail to penetrate the circuit board, resulting in scrapping. 5. Usually, a 40x stereoscopic microscope can be used to check the wear of the cutting edge of the drill bit. 6. Regularly check the concentricity of the spindle and spring chuck, as well as the clamping force of the spring chuck. Poor concentricity can cause small diameter drill bits to break and have large apertures. Poor clamping force can cause the actual speed to not match the set speed, causing slippage between the chuck and the drill bit. 7. The clamping length of the fixed Shank Drill Bit on the spring chuck should be 4-5 times the diameter of the drill handle in order to be firmly clamped. 8. Regularly check the spindle presser foot. The contact surface of the presser foot should be horizontal and perpendicular to the main axis, and should not shake to prevent drilling breakage and deviation during drilling. 9. The dust suction effect of the drilling machine is good. The dust suction wind can reduce the temperature of the drill bit, while taking away dust to reduce friction and generate high temperatures. 10. The substrate layer, including the upper and lower base plates, should be firmly positioned and leveled in a one hole, one slot positioning system on the workbench of the drilling machine. When using adhesive tape, it is necessary to prevent the drill bit from sticking to the tape, causing difficulty in chip removal and breaking the drill bit. 11. When ordering drill bits from manufacturers, 4% of them should be randomly inspected for compliance during factory inspection. And 100% of the specimens were examined for nicks, abrasions, and cracks using a 10-15x microscope.
When using a glass drill bit, we need to learn to choose the drill bit because the material structure of the glass drill bit is different. There are many types of glass thicknesses, some are thicker and some are thinner, so when using glass drills, it is necessary to choose based on the thickness of the glass. Some glass drills have a larger usage area, while others are lighter and thinner. When choosing a glass drill bit, try to choose some with better texture as much as possible, so that drilling is more convenient.
