Sharp Industries 220V 20” x 60” SHT Series Traveling Column Surface Grinder SHT-2060-2A

Description

This is a large size surface grinder suitable for grinding big, heavy work piece. To ensure smooth and steady movements, the cross travel is designed by having the vertical column travels in and out instead of the saddle. The table and column travels on T-shaped one piece casting base with TURCITE coated sideways.
