APPLICATION DESCRIPTION:
A sheet metal fabricator needed to perform multiple spot welds on lot sizes ranging from 50 to 100
pieces. No two lots had welds in the same locations; therefore, setup simplicity was crucial..
APPLICATION REQUIREMENTS:
• Two axis positioning system
• Teach mode
• Repeatability better than ± 0.005
• Speed = 25 inches per second
• Weld head load = 10 lbs
TOL-O-MATIC SOLUTION:
The SSC2 two axis controller with the Tol-O-Motion SSC user interface software provides a dedicated
joystick teach mode unlike any other for simplicity of multiple axis point-to-point programming. The flexible
SSC controller is capable of providing control for any of the Tol-O-Matic drivers (brushed dc servo,
brushless servo, or steppers) but since speed and torque requirements allowed the use of a low cost
stepper system, the MSD microstepping drives with the MRS stepper motors provided the most cost
effective solution. A B3S20 (2" cylinder-style body B3S Series screw-drive) was selected for the primary
axis actuator due to the large moment load generated by the secondary axis actuator, motor and load.
For the secondary axis a BCS15 (1 1 /2" cylinder-style body BCS Series screw-drive) actuator was selected.
