Double Column With Moving Beam CNC Grinder

Machine Introduction

The FPG-DC series stands out as the number one choice for double­column moving beam grinders The easy to use interface, full CNC user­friendly control system, total workpiece capacity and the rigidity and accuracy of the dual column design offers impressive performance

CHEVALIER's patented elevation guideways and spindle structure have four heavy-duty square slideways that provide maximum rigidity and heavy-duty grinding capacity The spindle head on the Y-axis runs on four hardened, ground and wider guides traveling on Turcite-B anti-fric­ tion material A worm gear reducer and servo motor coupled with a high­ accuracy ballscrew and a pneumatic counterweight balance system ensures smooth movement and prevents the head from crashing in case of a power failure 

A high-precision, cartridge-type spindle is equipped with four Class 7 (P4) angular contact ball bearings and a set of NN- type, precision-needle roller bearings

Patented Ground Beam Design

Box type double column design provides superior rigidity.

Patented Horizontal Beam Design

The cross rail design features linear roller bearings sliding on steel guide ways to ensure smooth, stick-slip free movement while the robust lower box way guides coated with anti-friction material provides maximum rigidity.

Unique Horizontal Beam Design

The elevator mechanism of the cross rail is driven by two ballscrews supported by a mechanical counterweight balance system for better positioning accuracy.

Both horizontal spindle and vertical spindle feature the interlock function capable of locking the cross beam whenever it is moved to ensure perfect alignment at all times.

The hydraulic braking system is very close to the horizontal beam, giving it instantaneous response when needed. A separate tank stores the hydraulic oil for this purpose.
