Most mechanical finishing operations require several stages to achieve the final result. According to Surtech, where large amounts of flat parts, such as sheet, strip, extrusions, hollow sections and so on, have to be finished, only a multi-head machine can cope.

With the correct number of heads, each fitted with an increasingly finer belt, it is possible to finish parts with a single pass through the machine and with a considerably faster feed rate than is possible with single-head machines.

A machine with between two and four heads will suit the majority of companies but for very high production rates or specialist finishes, four to six heads will be necessary to increase the feed rate.

Key product features

  • Through-feed machines are available in working widths of 150mm, 200mm and 300mm
  • Multi-head through-feed machines operate usually wet to prevent heat distortion of parts, to improve the finish and to extend belt life
  • Motor power per head is from 5kW to more than 10kW
  • Conveyors have variable speeds of between 1m/min to more than 10m/min
  • If parts are flat to within a few thou fixed heads are acceptable but for any parts with an uneven surface it is advisable to specify floating heads with a constant contact pressure control
  • In addition to standard features Surtech’s multi-head through-feed machines are available with many optional extras, such as motorised thickness settings, ammeters fitted to each head for control of contact pressures, oscillating belts for improved finishes and variable belt speeds to maximise belt performance
