The screws are being made in this stage while internal and external diameter of each part are being cut as well
Milling process
Square, unevenness and partly plane are processed.
Cylinder Grinding Process
Exterior diameter is being trimmed as precisely as +-0.005-0.001.
Plane part grinding
Plane, groove and a right angle is being trimmed as precisely as +-0.005-0.001.
Wire cut and electric discharge process
In this stage such complicate and precise process is achieved that cant be done by milling, lathe or other machine tools.
Measuring process and Partial assembling inspection
* Measuring process : Inspect whether or not the parts are manufactured
precisely at each process.
* Partial assembling inspection : A set is assembled in this process to see if it
properly works before it is assembled to main body.
