a. The framework is scrapped by hand which has high geometric accuracy. In order to increase the lubrication oil
reserve and decrease the friction coefficient.
b. The spindle adopts the world famous brand "ZWZ" with high accuracy double-row short cylindrical roller
bearing take the effect of centering in the process of running or rotating, because radial clearance of bearing
is adjustable; the worktable has higher rotation accuracy.
c. The cutter head device is composed of cutter head slide base and ram. The ram prefer the ductile iron
because of its ability to with stand shock loads, high tensile strength, and abrasive resistance.
d. All gears in adopt harden and grinding processing and have the advantages of stable drive, low noise.
The gears adopt 20 CrMnTi through hardening and grounding.
e. After the process of anneal and turning. The guide rail and worktable scrapped by hand sealed by oil slick
to make sure that they can run steadily.
