Wholesale CNC Crankshaft Grinding Machine

CNC Crankshaft Grinding Machine

Basic Data

The CNC Crankshaft Grinding Machine is a highly specialized, ultra-precision grinding center engineered for processing the main journals and crankpins (rod journals) of crankshafts. Utilizing advanced non-circular tracking (pin-chasing) grinding technology, the X-axis (wheelhead) interpolates dynamically with the C-axis (workpiece rotation). 

Core Technical Advantages
High-Speed Pin-Chasing Technology: The CNC system calculates the real-time eccentric orbital path of the crankpin, driving the wheelhead in a continuous tracking motion. This eliminates traditional eccentric fixtures and slashes changeover setup times.

Single-Clamping Process Integration: Grinds both main journals and eccentric pin journals in one setup. This direct sequence guarantees absolute parallel alignment and perfect phase-angle positioning between all journals.

Dynamic Balancing & Vibration Dampening: Heavy-duty Meehanite cast iron base features specialized dampening properties to handle the high-frequency reciprocating inertia forces generated during eccentric tracking grinding.

Closed-Loop Gauging & Profiling: Outfitted with specialized in-process crankshaft gauges (Marposs) that actively measure roundness and diameter profile errors during the active cycle, executing real-time micro-feed corrections.

Target Industrial Applications
Automotive & EV Hybrids: Mass production of lightweight, high-RPM passenger car crankshafts.

Heavy Transportation: Heavy-duty diesel engine crankshafts for commercial trucks and locomotives.

Marine Engineering: Medium-speed, high-torque marine diesel engine crankshafts.

Industrial Compressors: Precision eccentric shafts for refrigeration and air compressor units.
