Downfeed (minimum unit) : 5μ
■ Spindle & motor
2HP V3 grade low virbration spindle motor.
Cartridge-type spindle, ABEC Class 7 (P4) bearings, 0.003m/m TIR.
1 roller bearing at front and 2 angular contact ball bearings at rear side of spindle. (618)
1 roller bearing and 2 angular contact ball bearings at front, 2 angular contact ball bearings at rear side of spindle.
■ Base & slide ways
Cross double V and longitudinal V& flat, and TURCITE B coated with hand scraped, 3 axes are box ways.
One-piece casting base and slide way.
All main castings are made of "Meehanite GC275" and have been annealed stress for long lasting and accuracy.
■ Hydraulic design
