SMAC creates tapping process for watch maker
A
SMAC Europe product story
Edited by the Engineeringtalk editorial team
Mar 20, 2009
SMAC has developed a linear/rotary actuator, the LAR35 series, as a tapping process for a watch manufacturer in Switzerland.
The tap diameter is 0.38mm; the part has a diameter of 3mm and is 0.25mm thick.
SMAC has successfully automated a tapping process for a major watch manufacturer in Switzerland.
The LAR35 series has a 50mm stroke and is mounted vertically with the shaft looking down.
The custom tip is attached to the shaft end of the actuator to hold the tap.
The shape of the parts can be varied so that the customer can hold the part to tap manually, while the fixture is being developed.
SMAC's patented soft-land capability allows the tool to land on the part gently, move back 0.1mm, start the rotation, press the linear axis with a small force, check any variation on torque on the rotary motor to avoid failure and check the linear position when the tap reaches the required position.
The same procedure takes place in reverse.
For the SMAC LAR series, linear and rotary are combined in one unit.
With all SMAC actuators, force, speed and position are fully programmable.
