Since its founding in 1984, Lih-Jaan has earned a strong reputation for precision engineering, particularly in the field of building thread and cylindrical grinding machines. With decades of experience and a commitment to quality, the company became a trusted name in its industry. But as manufacturing demands evolved and the complexity of applications increased, Lih-Jaan set its sights on a new challenge: worm thread grinding.

This highly specialised process requires not only technical precision but also a deep understanding of machine control and customisation. To take this next step, Lih-Jaan needed a partner with the expertise and flexibility to support such an ambitious move. That is when it turned to NUM.

What began as an initial conversation around the NUMgrind software platform evolved into a strategic alliance driven by innovation and opportunity. A renewed momentum emerged when Lih-Jaan identified a specific market need, leading to a strengthened co-operation between the two companies. Working hand in hand, they developed a custom solution that combines flexibility, user-friendliness and the ability to support a wide range of worm thread profiles. Despite a few time-related challenges in the final stages, the joint efforts culminated in a successful machine delivery.

The result was a newly developed worm thread grinding machine. At its core: NUM’s Flexium+ 68 CNC system, paired with a version of NUMgrind and worm thread grinding HMI and MDLUX axes. The machine supports five different types of worm threads, including multi-start threads, and allows for both cylindrical and non-circular grinding – all in one set up.

“NUM’s total solution not only expanded our product portfolio but also enabled us to realise our goal of developing a specialized multi-tasking machine,” states Ava Tsai, sales manager at Lih-Jaan.
