Comparison of retainer grinding before and after
Efficient grinding of retaining rings on a grinding machine
Workpiece dimensions: Diameter 110mm
Grinding size requirement: 3.300mm±0.012
Machining process: Double-sided grinding thinning
Machining equipment: YHDM750 high-precision vertical double-end face grinder
Core advantages
1. Ultra-high precision and geometric quality
Dimensional accuracy: Easily achieves ±0.005mm or even higher thickness tolerances.
Parallelism/flatness: Double-end face grinding can process both sides simultaneously, with parallelism up to 0.003mm.
Surface roughness: Ra 0.2μm~0.8μm (after fine grinding), meeting the stringent requirements of hydraulic seals, bearing assembly, etc.
2. Excellent production efficiency
Double-sided simultaneous processing: The double-end face grinder completes the grinding of both sides in one pass, with efficiency more than twice that of a single-sided grinder.
Continuous automation: With an automatic loading and unloading system, 24-hour unmanned production can be achieved, and the cycle time can be shortened to 3-10 seconds/piece.
3. Process stability and consistency
Controllable process: CNC grinder can programmatically control the parameters (speed, feed, allowance) of the rough grinding, fine grinding, and polishing stages.
Batch consistency: Qualification rate can reach 99%+, reducing the cost of full inspection.
4. Surface integrity advantages
Burr-free: Grinding directly obtains smooth edges, eliminating the subsequent deburring process.
