High Precision Horizontal Hard Turning Machines

Hembrug hard turning machines are designed to process hardened steels, case-hardened components, bearing steels, and other difficult-to-machine materials typically in the 45–68 HRC range. They are well-suited for precision components such as bearing rings, gear shafts, hydraulic components, and tooling parts that demand tight tolerances and superior surface quality.

High-precision horizontal hard turning machines like those from Hembrug can achieve dimensional tolerances in the sub-micron to micrometer range, with surface roughness values as low as Ra 0.1–0.4 µm. These capabilities make them suitable as a direct replacement for cylindrical grinding in many precision component manufacturing workflows.

In many applications, hard turning can fully replace cylindrical grinding, reducing machine count, floor space, and tooling costs. However, for components requiring the absolute finest surface finish or extremely tight roundness tolerances, a combination of hard turning followed by finish grinding may still be preferred. WSM Technology can help you evaluate the right approach for your specific application.

Industries that benefit most include automotive (transmission, bearing, and drivetrain components), aerospace (precision shafts and housings), mold and die making, hydraulics, and medical device manufacturing. Any sector producing hardened, rotationally symmetric components with high precision requirements is an ideal candidate for horizontal hard turning technology.

Yes. WSM Technology provides complete turnkey solutions including on-site installation, operator training, and advanced training programs for all machines in their portfolio. Their team brings hands-on manufacturing experience across CNC turning, EDM, and milling, ensuring your team is fully equipped to maximize machine performance from day one.

Absolutely. WSM Technology operates a Demonstration Center in Rootstown, Ohio, where prospective customers can evaluate machines through live test cuts and time studies. This allows you to compare performance, prove out new technologies, and make confident purchasing decisions based on real results rather than specifications alone.
