In conventional induction hardening, it is not possible to suppress "hardening unevenness" or "hardening escape." Additionally, when using round coils for hardening, it is necessary to process both sides separately in two steps due to the unique shape of the idler and the areas that require hardening. In the case of Fuji Electronics, the workpiece is rotated and heated gently around its entire circumference by repeatedly heating and pausing with a unique semi-open coil, allowing for uniform hardening without unevenness. Furthermore, this method significantly reduces total power consumption and shortens cycle times, achieving high productivity. ★ For inquiries by phone, please contact us here: Osaka Headquarters → TEL: 072-991-1361 Nagoya → TEL: 052-322-1361 Tokyo → TEL: 03-5472-1361 *When calling, please mention "Ipros was seen."
