Grinding tool pins used in dental equipment demand ultra-high precision, superior surface finish, and consistent long-term performance. Below are the key manufacturing challenges and optimized processing solutions.
Material preparation → CNC turning / Swiss-type machining → Heat treatment (quenching & tempering) → Centerless grinding / Double-surface grinding → Surface treatment (hard chrome plating, QPQ, electropolishing) → Fine lapping / burnishing → Full inspection
| Process | Equipment | Target Specifications |
|---|---|---|
| Precision Turning | Swiss-type lathe / dual-spindle CNC lathe | Diameter tolerance ±0.01 mm, Ra 1.6-3.2 μm |
| Fine Grinding | High-precision centerless grinder | Cylindricity ≤0.005 mm, Ra ≤ 0.8 μm |
| Double-Surface Grinding | Double-surface grinding machine | Perpendicularity ≤0.02 mm, Ra 0.3-0.5 μm |
| Heat Treatment | Vacuum furnace / induction hardening | Hardness HRC 45-50, no deformation or cracking |
| Surface Treatment | Plating line / QPQ system | Wear-resistant, corrosion-resistant surface |
| Fine Lapping / Burnishing | Lapping / burnishing machine | Ra ≤ 0.2 μm, enhanced surface hardness |
Manufacturing high-performance dental grinding tool pins relies on precision machinery, mature processes, and strict quality control. The focus is on maintaining micron-level accuracy and ultra-smooth surfaces while ensuring material stability and batch consistency.
We have introduced advanced equipment and technology from Japan and Germany (CNC 5-axis and 6-axis machines) to better serve our customers' needs.
Our maximum processing outer diameter is 60, and the minimum control tolerance is 0.001. We have Japanese CNC Tsugami, CNC Citizen, multi-station cold extrusion forming machines, 500T press machines, casting equipment, and various process equipment.
Stainless steel screws, carbon steel screws, pins, rivets, nuts, eccentric nails, embedded parts, and other fasteners.
