Hello, everyone. Now I will introduce to you our rotary file shank cutting workshop. The workshop is equipped with dozens of CJK0620C CNC lathes, mainly responsible for the shank’s cutting and the welding parts’ installment. These CNC lathes are able to meet an annual output of 100 million rotary files.
Next, our welding workshop is responsible for the welding of the rotary files’ tapers and shanks with G15 high frequency welding machines.
The Instrument lathes in the shank workshop are utilized to make sure that the shank and the taper of our rotary files are homocentric.
This is our grinding workshop, which is outfitted with two hundred plus 5-axis grinding machines. They are all computer numerically controlled units. With these machines, the tapers of our rotary files are accurately machined, which ensures a high working precision and working efficiency.
After tapers’ grinding, shanks will undergo accurate grinding again with an M1040 CNC centerless grinding machine.
Then, semi-finished products will be sent to our testing workshop to check whether their size and precision are qualified, so as to ensure the final quality and accuracy of the finished rotary files.
