Chevalier FRG-400S/600S CNC Rotary Surface Grinder: Precision Meets Performance

The FRG-400S and FRG-600S Series are one series of Chevalier CNC rotary surface grinders. Designed to satisfy the changing needs of sectors like semiconductor manufacturing, automotive, aerospace, medical devices, and energy, these machines represent a major breakthrough in high-load precision grinding technology.

With features like a hydrostatic rotary table , C2-grade ballscrews , and linear guideways with sub-micron resolution , the FRG-S Series delivers unmatched performance in terms of rigidity, accuracy, and ease of operation — making it one of the most capable CNC rotary surface grinding solutions on the market today.

📌 Key Features of the FRG-400S/600S CNC Rotary Surface Grinder

1. Robust Spindle System for Heavy-Duty Applications

The spindle assembly is supported by six Class 7 (P4) angular contact ball bearings , ensuring high stiffness and long service life under demanding grinding conditions. This configuration allows the machine to handle large workpieces and maintain consistent grinding quality over extended operations.

Additionally, a flexible coupling connects the spindle to the motor, enabling precise balance correction and minimizing vibration. This results in reduced tool wear and superior surface finishes.

2. High-Precision Transmission Systems

Each axis of the FRG-S Series is equipped with advanced motion control components:

• Rotary Table : Utilizes a hydrostatic bearing system for smooth, low-friction rotation and minimal wear.

• Vertical Axis (Z-axis) : Driven by a C2-grade ballscrew and timing belt connected to an AC servo motor , delivering high torque and accurate positioning.

• Crossfeed Axis (X-axis) : Also uses a C2-grade ballscrew directly driven by an AC servo motor, enhancing grinding accuracy and enabling mirror-finish capabilities.

Both axes incorporate linear guideways with a minimum setting unit of 0.00004" (0.001 mm) , ensuring micron-level precision ideal for tight-tolerance applications.

3. Smart iControl CNC Interface

Chevalier’s proprietary Smart iControl system is designed to simplify operation while maximizing productivity. With intuitive touch controls, real-time diagnostics, and customizable presets, this next-generation CNC interface reduces operator training time and increases machine utilization.

It also supports integration into Industry 4.0 environments , allowing remote monitoring and data logging for predictive maintenance and process optimization.
