Advanced Motor Shafts Custom Machining

We process diverse motor shafts using stainless steel and alloy grades. Our facility excels in small-batch production, accommodating complex splines and keyway geometries.

Engineers benefit from our specialized surface treatments, including black oxide and electroless nickel plating. We ensure extreme straightness and cylindricality through secondary grinding processes, addressing critical fitment requirements for rotors and bearings while maintaining structural integrity under high torque.

Contact Our Team

How do you ensure shaft straightness after heat treatment?

Post-heat treatment, we utilize specialized precision grinding and straightening presses to counteract thermal distortion, ensuring the +/-0.005mm tolerance is maintained across the entire length.

Can you maintain concentricity between multiple diameters?

Yes. By using one-hit CNC turning or between-centers grinding, we keep the Total Indicated Runout (TIR) within strictly defined mechanical limits to prevent high-speed vibration.

Is material certification provided for aerospace or medical builds?

We provide full material traceability, including Mill Test Reports (MTR) and RoHS compliance certificates, ensuring the chemical composition matches your specific alloy requirements.

How do you handle IP protection for proprietary shaft designs?

All drawings are managed within a secure, encrypted PLM system. We regularly execute standard or custom NDAs to protect your geometry and application details before quoting.

What is your process for verifying spline and keyway accuracy?

We utilize CMM inspection and specialized go/no-go gauges to verify involute profiles and keyway alignment, ensuring a perfect interference or clearance fit with your mating components.

Do you offer expedited shipping for urgent prototype iterations?

For time-critical projects, we prioritize CNC setup and use express air freight to minimize transit, typically bypassing standard production queues when mechanical validation is the priority.
