Full programmability of all winding functions now available in a heavy duty floor stand machine. Forget about lengthy set- up times. The famous SMC control now allows all winding functions to be programmed for ease of repeatable recall at any time. The SMC-4 is a heavy sized floor stand machine for the winding of large size toroidal coils and is unmatched by any competitor for general winding and tap- ing applications. The ability to accept 4 types of winding heads along with 3 sizes of taping heads makes this machine the most versatile in its class. Core sizes from 3.5 inch (89.0mm) to 46.0 inch (1169 mm). Wire sizes from #38 awg (0.1mm) to #4 awg (5.4 mm).

Principal and optional features

  • Separate speed controls for loading and winding
  • Programmable servo motor driven core rotation in either direction with minimum backlash
  • Programmable wire spacing, from coarse to fine micro-step resolution
  • Electronic linear pick-up for loading (feet or meters)
  • Tape head controls
  • Solid-state microprocessor count controller with a total of 99 programmable presets/LED readout/built-in fiber optic turns sensor/program storage/production batch counter and the utmost accuracy, stability and reliability
  • RS-232 with interface software
  • Quick change winding and taping heads
  • Automatic core index function
  • Push button, on-off footswitch or variable speed footpedal operation
  • Optional SMC programming software to pre-calculate and download all winding parameters from your PC to the machine
