Universal/Raft Type Mini Mill Series

 



The Mini Roll Forming Mill is a universal-type Roll Former, designed for the small section and the price-conscious buyer. This Roll Forming Machine combines the same durability and precision found in our conventional roll formers. To accommodate an optional Raft-Type operation, each roll stand is driven individually by spring-loaded, quick-disconnect universal shafts and by a double-output shaft gear reducer. The reducer incorporates hardened and ground steel spur gears and bronze worm gears. All Roll Forming Machines are available with any number of stand and raft combinations to suit your specific requirements.

Specifications:

Pinion Stands
- Feature two output shafts on fixed vertical centers, mounted in anti-friction bearings, and driven by a worm gear set. Hardened and ground spur gears are mounted on the back end of horizontal output shafts and are accessible and easily changed to provide the necessary gear ratio for any specific application. Each pinion stand is a completely self- contained unit with its own oil supply and oil level sight gauge.

Mill Housings – Open-window design for mounting spindles, which are carried in bearing box assemblies with anti-friction bearings and proper lubrication fittings. The top spindle assembly is supported by large diameter adjusting screws, equipped with micrometer dials for fast, accurate settings. Engraved scales and pointers allow for rapid reference settings.

Top and Bottom Roll Spindles – These spindles are driven from the pinion stands by universal couplings. The quick-disconnect arrangement assures fast changeover of tooling. Universal couplings can be disconnected, when necessary, to idle roll shafts for certain forming applications.

Optional Features:

  • Complete line of auxiliary items available, such as adjustable Entry Tables, adjustable Side Roll Stands, Straightener Units, etc.
  • Roll coolant system reservoir built in, as an integral part of the base, with a centrifugal motorized pump.
  • Internal or external coolant tank option includes easily removable sediment separator in line between reservoir and pump.
  • Choice of fixed AC with air clutch/brake or AC/DC variable-speed drives.
  • Extra base length is available as part of original equipment, to increase machine capacity at a future date.
  • Raft option is available to reduce roll setup time.

Standard Features:

  • Tapered roller bearings in inboard stand with preload and shoulder alignment feature.
  • Hardened and ground outboard spindle sleeves that run in roller bearings.
  • Micrometer screw adjustment for accurate, repeatable top spindle adjustment.
  • Precision alignment of spindle shoulders.
  • Top and bottom spindles are driven through universal shafts from individual oil-tight gear reducers.
  • Mounted onto a cabinet-type or welded tubular constructed base, reinforced for rigidity, and accurately machined. Our forming machines are available with any number of stands to suit your specific requirements, present and future.
