*As the cycle time is reduced by the vacuum system which reduces Material feeding time, saves steam and produces superior cooling effect, the product not only saves cost but also realizes high productivity.
*As the coolant is injected in spray nozzle system equipped with separately installed coolant piping, the product surface can be polished more effectively.
*As all controls are operated full automatically, unmanned automation is realized.
*HN-306VA is equipped with hydraulic drive system by which perfection-clamping and right balances circuit system enables durability to be superior
*HN-312VS is equipped with hydraulic drive system balance circuit system eanables durability to be superior.
