This device features a design with the oscillator, control panel, machinery, and water tank combined in a single housing, resulting in a compact size. Since it can be transported by a single 4-ton truck and fits inside a shipping container, we have an extensive track record of not only delivering this product within Japan, but also exporting it to many foreign countries. Startup work for this product can also be carried out in a short time. Its versatility and ease of maintenance make it the ideal next-generation numerical control hardening equipment for the small parts used in 2- and 4-wheel vehicles.
