N/C models are also available with a variation of stepping motor combined with a hydraulic torque amplifier. Essentially, the motor drives the torque amplifier which. in turn, drives the table lead screw.
This combines the high accuracy of the SLO-SYN motor with the powerful torque capabilities of the hydraulic drive. Models utilizing these hydraulic amplifier drive motors can provide up to 16,000 ounce-inches of torque.
The SLO-SYN Hydraulic Linear Actuator converts a hydraulic cylinder operated tracer mill into an N/C contouring mill. It consists of a SLO-SYN Continuous Path Contouring Control plus motors and hydraulic valves for each axis.
The valves control hydraulic flow to the existing hydraulic cylinders and are controlled by the N /C through pilot lead screws. The pilot lead screws are not supplied.
The resulting control system adds the flexibility of contouring tape control while retaining the smooth power flow and high torque capability of the original hydraulic system. Complex parts can be produced quickly with greater accuracy than is possible with a tracer mill and the need for a tracer head and templates is eliminated.
