Compact Type End Face Polishing Machine "Heso Tori-kun"

Simple is best! Compact type end face polishing machine.

Heso-tori-kun is a compact edge polishing machine that seems like it should exist but doesn't. It is ideal for removing "navel" areas near corners, as well as "joint marks" and "overlap seams," which are difficult to address with conventional disc grinders or belt sanders. Heso-tori-kun excels particularly in processing small quantities of 1 to 5 workpieces. Thanks to its uniquely developed table function, it can also handle tapered edges of thick plate products, demonstrating stable navel removal performance. 【Features】 ○ Ideal for small quantity workpieces ○ Easy removal of navels on product peripheries ○ Compact and lightweight for easy portability ○ Safe and secure operation with both hands, reducing fatigue ○ Capable of accommodating laser beam tilt For more details, please contact us or download the catalog.

Low voltage circuit power transformer LST lightning-resistant transformer

The key to lightning surge protection!! An excellent surge suppression mechanism quickly guards electronic devices.

This trans system is equipped with arresters (lightning protectors) in its primary (input) and secondary (output) circuits. The arrester effectively acts against induced lightning surges or internal lightning phenomena; however, it may not be able to protect the equipment being safeguarded if it encounters impulses beyond its performance or direct lightning surges. The main component of this system, the power transformer, uses high-quality insulating materials at key points to function safely against lightning surges and has an extremely high insulation resistance.
