1) The hydrostatic bearing spindle front end, back-end using the contact angle of two high precision ball bearings to ensure precision and stability. 
 2) The back wheel of the sliding surface by hydrostatic pressure lubrication, can turn smooth sliding surface for a long time to maintain high precision. 
 3) have been precision slide surface scraping, and paste the wear-resistant slider TURCITE B, the mobile stable, prolonged use of the same precision. 
 4) continuing through the electric oiler to oil, to ensure that slide surface lubrication. 
 5) axis electronic hand wheel up and down a grid feed as 0.001mm.
