Chevalier Automatic Surface Grinder, 8" x 18"

Series features a smooth and accurate movement with low friction to ensure high accuracy and longer way life. The proximity switches let the operator set the right stroke for each workpiece. The precision 0.0001" graduated microfeed device (worm and wormgear design) ensures precise positioning of the cross axis.

This automatic surface grinder has been specially developed and recently improved to continuously offer reliable high-performance precision surface grinders. The high-precision FSG-3A series surface grinder has recently improved the control panel with easy to read LED numerals. Chevalier offers a one year limited-warranty that includes parts for mechanical and electrical components.

The Double-V crossfeed guideway span has been designed by applying kinematics to calibrate for minimum bending moments, thus achieving maximum support capability for table and workpiece.

All essential castings are made of a high-grade cast iron that is stress relieved by annealing, ensuring the greatest stability and rigidity with lowstress.

An interlock is placed between the electrical cabinet door and the power supply as an added safety feature. The maximum distance from table surface to spindle centerline is 450mm (177"), which provides more clearance for grinding.
