Supertec

Feature

Some of the more popular features of the saddle type design are:

Double "V" ways on longitudinal and cross ways

3 HP spindle motor (SG-1020) 2 or 3 axes

5 HP spindle motor (SG-1224) 2 or 3 axes

7.5 HP spindle motor (SG-1632)

Auto down feed driven by AC servo motor with rapid up/down on 3 axes

Auto lube system

Extra low noise & low temperature growth on hydraulic system & spindle assembly Twice annealed casting for greater stability

Low-friction coated surfaces-slideways are hand scraped & coated with Turcite-B

Spindle run-out 0.0001" TIR

Hardened and ground box ways on vertical travel

Double "V" slideways on the table provide greater rigidity and more accurate longitudinal table movement.

Precision ground and Turcite "B" coated. Extra wide double "V" ways on the cross slide to increase machine rigidity and grinding accuracy.

Column type base utilizes double "V" slideways on the table that are hand scraped and Turcite "B" coated for greater rigidity and smoother movement.
