DRG-6

Rotary Surface Grinder

Micron-Level Precision,
Maximum Efficiency
3 Times Higher Productivity than Reciprocating Type
The DRG-6 integrates a high-precision ram structure with a full-axis servo motor drive, achieving both exceptional accuracy and high productivity. Through precise grinding volume control, the machine ensures consistent, stable quality across all workpieces on the table.

Example of Machining a Representative Workpiece

Material: S45C   Flatness < 3 μm  
Outer Diameter: 385 × 30 mm   Double-Sided Machining Time ※ 6 min  
  ※ Double-sided machining time = Single-side machining + Reversal + Single-side machining
Machining Time Comparison:
Processing time per workpiece reduced by approximately 47.4% . Machining Time Comparison

Triple Productivity Performance

The rotary table design boosts machining efficiency to up to three times that of a conventional reciprocating surface grinder.
It covers a wide workpiece area in a single setup, minimizing reciprocating travel and clamping frequency.
As a result, machining time is shortened, per-piece cost is reduced, and overall productivity is greatly improved.

Variable-Speed Motion Control

During table rotation, the outer area operates at a lower speed while the center runs at a higher speed.
The system automatically coordinates precise acceleration and deceleration according to the spindle feed rate, ensuring a stable and consistent grinding volume across all positions.
This feature greatly enhances machining quality stability and significantly boosts overall production efficiency.
