The gripper arm is the component for tool gripping.

It consists of an aluminium central structure and hardened steel tool pick-up.

Tool pick-up and release are performed by spring mechanism. Both are due to arm rotation which engages or disengages tools in tool change position.

Starting positions are mechanically controlled by cam exchanger. Then, once timing is defined and gripper is mounted on shaft, position repeatability is absolutely secure.

 

The group TMA 40 is a ring magazine with elastic grippers appropriate for tool changers with a  “pick and place “ system.

It can be realized in the continuous version operated by servomotor run by an encoder, or in the version step by step operated by an self braking motor through a cam mechanism. The elastic grippers employed are made of plastic or steel, or self braking gripper can be mounted for cones ISO 40 and BT40, HSK 50 and 63 and cones Capto C58 and C6.

The structure is completely realized in aluminum with inserted guides in antifriction plastic material

It is produced in a standard version with ability of 24-40-60 and 80 tools. The standard speed of the magazine is of 50 m/mins.

Due to its manufacturing modality, the TMA 40 doesn’t need periodic tensioning to eliminate slack.

The TM tool magazine is composed of a cam rotary table, moved by a self-braking gear motor, carrying a plate with elastic grippers.

The CUT and HTC tool changers are mechanisms whose purpose is to transform the uniform input rotary motion into an given sequence of intermittent, linear and rotary motions of the output shaft, by means of a cam.

The synchronized combination of the movements made by the toolchange gripper double-arm results in the typical tool changing cycle, i.e. the characteristic feature of this device.

CTM  tool changer is suitable for installations on NC milling machines, vertical and horizontal work centers and it is manufactured in the different sizes according to the type of tool holder.

For each size there is a corresponding magazine having a capacity of 12, 20 or 30 tools in standard versions and 24, 40, 48 or 60 tools in the special ones.
