Chucking tools such as spring collets, feed fingers, guide bushes etc., which are used for multi spindle drilling machines, gear cutting machines, automatic lathes, and other specialized machines, usually have problems of accuracy and accuracy maintenance, breakage, spring-elasticity and deformation, which cannot clearly be identified merely by their external examination or measuring. YUKIWA SEIKO have managed to largely solve these problems by means of strict selection of raw materials, proper heat treatment and through a wealth of manufacturing experience. As a specialist manufacturer of collets, we have the largest production volume and range in Japan. The unrivaled quality of our products is highly appreciated. |
