Two Roll Bending Machines

Every model in Acrotech’s unique line of Two Roll Bending Machines is designed and built for production and precision. These machines will roll a variety of materials and configurations into cylinders with virtually no flats on the ends!

Built to meet the demands of production involving small, light gauge parts. Pneumatic lock-up is standard on all models for increased productivity. 120V 1PH standard wiring simplifies installation. 220 or 440V 3PH wiring is also available.

Roll Bending Optional Accessories

  • Tooling Slip on Tubes – when the diameter required is larger than what the top shaft will produce, a Slip-On Tube is used. The tubes are developed per part size and increase the forming diameter capability of the top shaft. Quickly change the tube by simply slipping them on and off the top shaft as needed. A Slip-On Tube will be required for each specific part.
  • Slip-On Tube Support – facilitates removal of finished piece-part. Adjustable in height, this accessory supports slip-on tubes to prevent inching curved cylinders against lower roll when removing finished parts.
  • Small-OD Mounting Fixture – required for rolling parts smaller in diameter than the standard top roll.
  • Small-OD Shaft Assembly – available in various lengths and diameters for rolling material to a diameter smaller than standard top roll. Must be used in conjunction with Small-OD Mounting Fixture. Permits rolling diameters as small as one inch.

Normally our rolling machines are standard with our 90A Durometer Urethane Roller. This provides a general all-in-one type of roller capable of handling thick to thin metals and able to be delicate enough to handle pre-cut and perforated metals. In addition the medium-hard 90A durometer has slits cut in the roller to help aid in dispersing loads. Works great for most but there are some applications where it is just too hard. We are currently building a custom unit for a customer with an 80A durometer roller on it to provide a very delicate surface for forming extremely thin and pre-cut materials. This roller does not have the slits cut in it because it would further the possibility of it marking the sensitive materials. The material is precision ground to the correct diameter and mated up to the die roller for a perfect and consistent roll every time. This is a combination that will allow very delicate, thin and decorated metals to pass through without issue.

Below You will see pictures of our small O.D. Attachment installed on a 1618. This will allow you to roll much smaller parts (as small as 1″ in diameter) with precision and complete repeat-ability. This attachment can be fitted to new machines or units that have already been in service for years. No reason to buy a new unit when we can customize tooling to fit your needs.
