• Product Introduction
-
| Total Quick Changing of The Tools for Drilling, Boring, or Milling. Epoch-making quick change tooling system, design as a total system, for special purpose machines. Thanks to the duplex-holding system by the taper and the flat surface, the working accuracy and the repeatability are excellent. Thanks to the short and tapered shank, the tool changing can be done even in a very limited space. |
|
Outstanding High-Precision and High Rigidity. |
|
| Press contact of the flat surfaces of the spindle and the chuck is directed by the taper contacting, which brings about excellent runout accuracy, boring precision and repeatability of tool changing, and also minimizing slight waviness at the machining and thus enabling to suit for heavy duty cutting. |
|
Minimized working space for tool changing. |
| Due to the short and tapered shank, the tool changing is possible even in a very limited space. |
|
Safety and Assurance. |
| The locking od the chuck to the spingle is secured by the eccentric-pin and the steel balls, ensuring the locking event at an emergency stoppage as well as in such machining of both CW and CCW rotations at the tapping work. |
