Precision Raceway Finishing
Automatic Raceway Detection
High-precision sensors enable automatic raceway detection.
Automatic Oilstone Feed
The screw superfinishing machine feeds the finishing oilstone automatically as it wears.
Direct Servo-Driven High-Frequency Oscillation
A servo motor directly drives oilstone oscillation to improve raceway roughness, waviness and profile accuracy.
Technical Specifications
Lead Screw Raceway Superfinishing Machine
| Representative Model | RSQYCJ-IIG |
|---|---|
| Shaft Outside Diameter | φ12~φ85 mm |
| Length | 50-350 (braking screws; unit not stated in source); 450-1,000 mm (RP screws) |
| Effective Range for RP Rack Screws | An 80 mm clearance at the workpiece clamping position (180-320 mm). The relationship between these dimensions requires confirmation. |
| Surface Roughness After Polishing | Ra 0.05-0.09 (approximately Ra 0.16 before polishing); Ra 0.10-0.15 (approximately Ra 0.26 before polishing). The source omits the Ra unit; confirmation is required. |
| Waviness | Within 0.04 μm in the effective region (for example, points 50-400 of a 400-point measurement), or inspected to drawing requirements. The measurement definition requires confirmation. ![]() |
| Polishing Unit Oscillation Angle | ±4° |
| Polishing Unit Oscillation Frequency | 0-50/s (adjustable) |
| Cycle Time | 50~300 s |
| Driving Method | Centers / Chuck |
