⒈The drill bit should be packed in a special packaging box to avoid vibration and collision.
⒉When used, the drill bit should be installed in the spring collet of the spindle or the tool magazine for automatic drill bit replacement when the drill bit is taken out of the packaging box. Put it back in the box immediately after use
⒊Measure the diameter of the drill bit with a non-contact measuring instrument such as a tool microscope, to avoid the cutting edge from being touched by the mechanical measuring instrument and being scratched.
⒋ Some CNC drilling machines use a positioning ring. Some CNC drilling machines do not use a positioning ring. If the fixed ring is used, the depth positioning of the installation must be accurate. If the positioning ring is not used, the extension of the drill bit to the main shaft must be adjusted to be consistent. , Multi-spindle drilling machines should pay more attention to this point, to make the drilling depth of each spindle
consistent. If it is inconsistent, it may cause the drill bit to reach the table or fail to penetrate the circuit board and cause scrap.
⒌Usually a 40x stereo microscope can be used to check the wear of the cutting edge of the drill bit.
⒍ Always check the concentricity of the main shaft and the spring chuck and the clamping force of the spring chuck. If the concentricity is not good, it will cause the small diameter drill to break the drill and the hole diameter is large. The set speed does not match, and the chuck and the drill bit slip.
⒎The clamping length of the fixed shank bit on the spring chuck is 4 to 5 times the diameter of the drill shank in order to clamp it firmly.
⒏ Always check the spindle presser foot. The contact surface of the presser foot must be horizontal and vertical to the main shaft, and should not be shaken to prevent drill breakage and deviation holes in the drilling.
⒐ The dust suction effect of the drilling machine is better. The dust suction air can reduce the temperature of the drill bit, and at the same time take away the dust to reduce friction and generate high temperature.
⒑The substrate stack including the upper and lower backing plates should be positioned and laid flat in a hole and slot positioning system on the workbench of the drilling machine. The use of adhesive tape should prevent the drill bit from sticking to the cutting tape on the tape, causing difficulty in chip removal and broken drill.
⒒ Order the manufacturer's drill bit, at the time of factory inspection, it is necessary to check whether 4% of it meets the regulations. And 100% using 10 to 15 times microscope to check for notches, scratches and cracks.
I believe that everyone now knows how to use glass drills. When we use glass drills, we must learn to choose drills, because the material structure of glass drills is different. There are many kinds of glass thickness, some glass is thicker, some glass is thinner, so when using glass drill, you need to choose according to the thickness of the glass. Some glass drills have a larger area of use, while some glass drills are lighter and thinner. When choosing a glass drill, try to choose some of the better texture, so that it is more convenient when drilling
To ensure the quality and the requirements of the drawings can be met before mass production
1st:, Start to prepare the RTP powder as per customer’s requirement with our wet-grinding machine
2nd, Before mass production, do a trial pressing and sintering using mould,
3rd, Check the appearances and the sizes of the samples with micrometer, projectors etc.
Test process of Good impacting Tungsten Carbide mining insert tips for drilling hard materials
1st,Mass production, press the raw materials to shape blanks,
Notes: all carbide stud pins blanks must be passed by semi finished inspection
2nd,Sinter blanks to finish (HIP) and finished products inspection,
Notes:10 sets of vacuum sintering furnace and 2set of HIP in the factory ensure the best quality and production capacity.
3rd,Cleaning/tumbling to make the carbide stud pins clean and nice surface.
Packing of Good impacting Tungsten Carbide mining insert tips for drilling hard materials
step 1, wrapped carbide stud pinsr in paper to avoid carbide stud pins be broken
step 2, put the carbide stud pins in inner small carton box
step 3, put the inner box into outer carton and fill the carton with foamed plastic
step 4, wrap the carton with packaging tape
