CNC Machined Involute & Parallel Spline Shafts

At XML Tech, we specialize in manufacturing premium, custom CNC machined involute and parallel spline shafts designed to withstand high torque, reverse shocks, and intensive rotational loads. Spline shafts require extreme manufacturing accuracy to ensure seamless power transmission without mechanical backlash.

Leveraging state-of-the-art multi-axis CNC milling, turning, and precision spline hobbing machinery, our factory produces both internal and external spline configurations for global OEM clients in heavy machinery, automotive driveshafts, robotics, and industrial power transmissions.

Technical Capabilities & Specifications:

• Spline Configurations: Expert production of both Involute Splines (for optimized stress distribution and self-centering) and Parallel / Straight-Sided Splines (for reliable sliding fits and high-torque capacities).

• Tight Tolerance Control: We lock in critical tooth-profile tolerances down to $\pm0.005\text{mm}$, ensuring perfect mating alignment and zero rotational lag.

• Advanced Metallurgy & Hardening: Processed from ultra-durable carbon alloys, stainless steel, or specialized gear steels. We provide in-house heat treatments (induction hardening, nitriding, or carburizing) to maximize wear resistance.

• Elite Geometric Accuracy: High-speed multi-axis machining guarantees exceptional concentricity and straightness, eliminating rotational vibrations at high RPMs.
