High-Precision Air-Static Spindle Bushing | Dedicated for PCB Micro-Drilling Machines
- Features
- • Aerodynamic Flow Design: An exclusive angled air groove design perfectly guides high-pressure air, achieving stable levitation, efficient chip evacuation, and heat dissipation.
- • High-Rigidity Auto-Alignment: An extreme precision taper design effectively reduces spindle radial run-out during high-speed operation.
- • Ultra-Precision Mirror Polish: Maximizes air-tightness and the uniformity of pneumatic buoyancy support.
- • Advanced Multi-Axis Machining: Combines 5-axis CNC milling with sub-micron centerless grinding to ensure the strictest geometric tolerances.
Description
Air-static spindle bushing engineered for high-speed PCB drilling machines. Featuring ultra-precision air grooves, it provides zero-friction, low-thermal-deformation support for ultra-high speeds, significantly enhancing micro-drilling precision and spindle lifespan.
- Selected Materials: High-grade stainless steel (SUS440C) / High-carbon chromium bearing steel (SUJ2) / Chromium-molybdenum steel (SCM). Optional DLC (Diamond-Like Carbon) coating is available.
- Applications: PCB high-speed micro-drilling machines (for spindles operating at 100,000 to 300,000+ RPM), semiconductor dicing and packaging equipment, and ultra-precision mold machining centers.
