2.- Sequence of cycle motions The angle of rotation of the gripper for engaging and releasing the tool is 90 or, on demand, 60а. The tool exchange rotation is 180. Standard extraction and insertion stroke varies as relevant taper (See Tab.1). Fig. 1 - Sequence of the Tool Change cycle. > 1- General The CUT devices manufactured by COLOMBO FILIPPETTI are mechanical, machine-independent tool change assemblies which, by means of a cam drive, transform an incoming uniform rotary motion supplied by a gearmotor into a regular series of stop-and-go linear and rotary movements of the output shaft...

4.- Danger area Since it is a positive-action arrangement, the gripper arm moves only within its range. Apart from switching-off, stoppage can occur only owing to an overload of the drive motor, to action by a torque limiter or to breakdown of some internal part. It is therefore essential not to enter the range of action of the device while it is in operation. When carrying out maintenance, the power must be cut before access to the danger area. > Outside diameterExtractionstrokeof the grippers Fig. 3 - Danger area 5.- Examples of applications CUT tool-changers can be used for machine tools...

The tool changers come in the following versions: 12.- Maintenance CUT assemblies require very little maintenance. Check the box regularly for oil leakage, always a sign of malfunctioning of the assembly or wear of the seals. If any is noticed, proper maintenance should identify and eliminate the cause. When carrying out routine servicing, and in any case after 8'000 hours of operation, the CUT assembly gripper shaft should be checked for backlash; if necessary, the whole assembly should be overhauled. Always ensure that there is unrestricted free airflow for motor cooling purposes, and...

15.- Mounting positions of the reduction gear. CUT tool changers can be fitted with a self-braking gearmotor or simply with a worm screw reduction gear. They can be mounted in 6 different positions on the CUT assembly. D1 D3 D4 S1 S3 S4 Fig. 9 - Positions of the reduction gear Since the CUT assemblies may be provided with other drive systems than the standard ones, such as combinations of clutch-brake couplings, speed change gears, etc., all dimensional and technical features of these devices must be specified. On demand, these can also be supplied directly by COLOMBO FILIPPETTI. 16.-...
