Overview
This SG-618 surface grinder model has a wire rope type grinding table where the bottom of the table slide way travels along the top of the saddle way. Since both slide ways are in full contact along the entire travel distance, it gives adequate support to the grinding process. Unlike other models, where the table travels on ball bearing ways with only point to surface contact, this design lends to more accurate grinding process.

- Bed type construction
- Smooth wire-rope driven table
- Hardened and ground lead screw
