Chevalier Grinding Machinery

Rotary Surface Grinder
with Hydrostatic Turntable

• The rotary table is designed with hydrostatic bearings, which support the worktable through a uniform oil film, providing the mechanism with high vibration resistance and higher rotational precision than conventional bearings
• Adaptive finish program to adjust table rotation, infeed speed and grinding wheel speed for better finish
• The spindle is supported by six Class 7 (P4), ultra-precision angular contact ball bearings that can withstand heavy-duty grinding
• In-machine Dynamic Balancing allows operators to adjust the grinding wheel balance and limit wheel vibration to less than 1 um
• The brand-new spindle elevating mechanism and front-to-back transmission mechanism of the machine are equipped with linear guideways and ballscrew, combined with servo motor for direct transmission
• Optimized structure for maximum rigidity for maximal precision and efficacy

Chevalier Fixed Beam Double Column Grinder

• High precision cartridge type spindle is equipped with four pieces of Class 7 (P4) angular contact ball bearings plus a set of N-N needle roller bearings in front of spindle.
• Precision ball screws (C3 grade) on cross-feed and down-feed axes are directly coupled to Delta AC servo motors.
• Roller type linear guideway design for longitudinal movement of spindle head
• Automatic cycle + continuous flow lubrication system for guideways, ball screw and table.

Chevalier Surface & Profile CNC Grinders

• Precision ball screws on cross-feed, elevating and table.
• All 3 axes are AC servo motor driven which is suitable for creep-feed grinding.
• FANUC OiMF 3 axis CNC control with 8.4” LCD Mono Screen
• 20HP FANUC β12/7000i spindle motor directly connected to spindle with flexible coupling
• Capable of profile (contour) grinding, form grinding and step grinding with automatic wheel dressing and compensation
• Column traverses on precision roller bearings on hardened and ground guideways.
• Run-hour display, PMC-L Ladder Search, Instruction Display and G-Code Menu Display are all included as standard control features.

Chevalier Manual Surface Grinders

• All essential castings are mode of high grade Meehanite ®cast iron that is stress relieved through annealing to eliminate internal stress.
• With the greatest stiffness and stability of the castings, this machine is suitable for both precision surface grinding and form grinding.
• The interlock between electrical cabinet door and power supply is established to ensure safe operation.
• The spring loaded type table travel stops will dampen the over travel caused by abnormal operations.
• Saddle travels on Turcite-B coated and hand scraped double V guideways.

We offer the following:
Manual Surface Grinders (M Series) – FSG-618M
Manual Surface Grinders (SP Series) – FSG-618SP / 818SP
