SMK304 Internal Thread Grinding Machine

Core ApplicationPrecision machining of internal threads for planetary roller screw nuts in robots.

Key Advantages

1. Micro-precision MachiningWith a minimum machining diameter of 5 mm, it is compatible with micro screws used in robot joints, satisfying the requirements for small-bore, high-precision internal threads.

2. Integrated Rough and Finish Grinding with Dual SpindlesRough grinding and finish grinding are accomplished in a single clamping setup, eliminating errors caused by secondary clamping. Processing efficiency is increased by approximately 40%, while surface roughness and geometric accuracy are more consistent.

3. High Precision for Robot ApplicationsThread pitch diameter tolerance, pitch accuracy, and profile accuracy meet the C5–C3 grade requirements for screws in humanoid robots and industrial robots. It is also compatible with multi-start thread raceways.

4. Stable Machining for High Aspect Ratio WorkpiecesThe anti-collision and rigid structure is optimized for internal threads of long nuts, making it ideal for mass production of reverse-type planetary screws for robots.

SWM1503 External Thread Grinding Machine

Core ApplicationMachining of external threads on planetary roller screw shafts for robots.

Key Advantages

1. Perfect Matching with Internal ThreadsDesigned specifically to achieve assembly-level matching accuracy with workpieces processed by the SMK304 internal thread grinder. It ensures uniform meshing clearance between internal and external threads, improving the load capacity and service life of the screw assembly.

2. Efficient and Stable Mass ProductionSuitable for multi-start threads and high-precision thread profiles with excellent batch consistency, meeting large-scale delivery demands of the robotics industry.

3. Balanced Rigidity and PrecisionEquipped with a highly rigid bed and spindle system, it produces minimal vibration during machining, guaranteeing the straightness of long shaft screws and high thread accuracy.
