Precision Rebuilding. Restore Performance.
The full range of AMC-SCHOU CNC-controlled crankshaft grinders is equipped with Siemens 828D CNC systems. They offer fast and highly automated operation, with the flexibility to grind various crankshaft models on one machine.
They are an ideal solution for production engine remanufacturers or performance crankshaft manufacturers who re-grind or manufacture various crankshafts, with an annual capacity of up to 50,000 pieces.
The investment in one K 1200-CNC is around 1/5–1/4 of that of a production-line orbital grinder.
Not only does the machine require less investment, but the unique AMC-SCHOU faceplate with pot chuck system also benefits customers by allowing them to change to another crankshaft model within 10 minutes, including stroke adjustment and centering.

Features
Rigid yet lightweight cast iron construction, with stress-relieved bed and table, ensures long-term stability and sustained precision of the K 1200-CNC, proven by thousands of installations worldwide. The flexible design allows quick changeover between different crankshaft models within minutes.
15” touchscreen combined with an industrial-standard control panel provides an intuitive interface, suitable for both CNC operators and technicians experienced with manual machines.
Probe-based thrust position detection enables automatic journal-to-journal alignment for both new crankshaft production and remanufacturing.
CNC-controlled grinding wheel feed for roughing, finishing, and spark-out cycles.u000bHigh-precision SKF ball screws and linear glass scales ensure positioning accuracy down to 0.0005 mm increments.
CNC-controlled dressing device maintains the grinding wheel condition on face, sides, and radius automatically.u000bIntegrated wheel diameter compensation ensures tight tolerances on all journals.
Key components such as bearings, control systems, ball screws, and electrical parts are sourced from leading European manufacturers, ensuring high performance, durability, and global service support.
In addition to conventional abrasive wheels, high-speed CBN grinding wheels are available for high-volume production, offering reduced dressing and increased cutting efficiency.
OPC UA interface supports remote monitoring and integration with advanced production management systems.
The AMC-SCHOU AAEM system enables in-process measurement of roundness and diameter of each journal, with automatic loading and unloading of the Y-type caliper via program control.
Available with basic guarding or full enclosure, compliant with CE, UL, and other safety standards.
