What accuracy standards do your CNC gears and splines meet?
We manufacture precision gears and splines to ISO 6-8 or AGMA 10-12 standards, depending on your requirements. We use advanced hobbing and shaping processes to ensure optimal tooth profile accuracy and minimize backlash for your robotic joints.
Can you perform heat treatment to increase wear resistance?
Yes, durability is key for transmission parts. We offer comprehensive heat treatments including Carburizing, Nitriding, and Induction Hardening. We can achieve hardness levels up to HRC 58-62 to ensure your gears and shafts withstand high-cycle robotic operations.
How do you control runout on drive shafts and harmonic drive inputs?
To prevent vibration, we utilize precision cylindrical grinding. We maintain strict Total Indicated Runout (TIR) of <0.01mm on critical bearing journals and shaft surfaces, ensuring smooth, concentric rotation at high speeds.
Are you capable of machining complex splines for harmonic drives?
Absolutely. We specialize in machining complex internal and external splines commonly found in Harmonic Drive flexsplines and circular splines. We use Wire EDM and precision broaching to achieve the intricate geometries required for high-reduction gearing.
Do you provide inspection reports for gear tooth profiles?
Yes. For gear and spline projects, we provide detailed inspection reports verifying tooth lead, pitch, and profile errors. We use CMM and specialized gear measurement tools to confirm the components meet your specified transmission class.
Can you machine custom flanges to interface with RV reducers?
Yes, we machine custom adapter flanges and mounting plates tailored to fit standard RV reducers . We ensure precise bolt circle positioning and pilot bore tolerances for seamless integration into your robot arm assembly.
