Engineered for Medical, Orthopedic & Robotics Manufacturing Excellence
The G32-SP is not just a grinder; it’s a precision manufacturing system designed to meet the extreme tolerances, complex geometries, and superior surface integrity demanded by the world’s most advanced industries. For manufacturers of surgical instruments, artificial joints (hip/knee stems), spinal implants, robotic actuators, and miniature high-precision components, it delivers unparalleled accuracy, flexibility, and process reliability.
Why the G32-SP is the Choice for Critical Applications
- Uncompromising Precision for Life-Saving Devices:
- Achieves ≤ 1.5 µm roundness and ≤ Ra 0.4 µm surface finish, meeting and exceeding the stringent requirements for implantable medical devices and friction-critical robotic components.
- HEIDENHAIN 0.1µm encoders and SIEMENS 828D CNC provide the nano-level control needed for micro-features on surgical tools and delicate robot parts.
- Superior Stability for Challenging Materials:
- The hydrostatic X-axis and rigid T-bed structure eliminate stick-slip, ensuring vibration-free grinding of difficult-to-machine materials like titanium alloys, cobalt-chrome (CoCr), ceramics, and stainless steels commonly used in orthopedics and robotics.
- Integrated thermal management (bed cooling, spindle chiller) guarantees consistent accuracy over long production runs—critical for batch consistency in medical device manufacturing.
- Flexibility for Complex Geometries:
- The multi-position servo turret allows seamless integration of different wheel shapes and sizes in a single setup. Ideal for grinding contoured stems, tapered shafts, intricate grooves, and micro-bores found in complex implants and miniature gearboxes.
- High-speed 24,000 rpm internal spindle is perfect for precision grinding of small diameters in instrumentation housings or robotic linkage bores.
- Process Integrity & Documentation:
- Standard in-process gauging (Tokyo Seimitsu) enables closed-loop grinding, reducing human error and ensuring every part meets spec—essential for traceability in regulated medical industries.
- The robust system ensures minimal part deflection, crucial for maintaining the dimensional integrity of slender components like bone rasps or robot arms.
