a Working table adopts hydrostatic guide way.
b.The spindle is to use model NN30(Grade D)bearing and able to turn precisely.
c.Gear case is to use 40Cr gear wheel of gear grinding,which has high precision
and little noise
d.Plastic coated guide ways are wearable
e.Centralized lubricating oil supplying is convenient
f. Castings of lathe are to use lost foam foundry(short for LFF)technique.Castings
are wearable with good quality and dealt by aging.
