310 Series

The WDM 310 Series plate roll is built primarily for the sheet metal industry and small maintenance shops. The 310 has been simplified to a no hydraulic/all electric design. Both the roll drive and the power bending adjustment drive (optional) are powered by an electric helical gear motor.

Latch Handle

One benefit of the 310 series is the updated latch handle. It can now be unlocked under bending pressure to release the top roll.

Dual Guarded Foot Switch

This is a dual guarded foot switch to start the rotation in forward/reverse. It comes standard with the 310 series.

Safety Cable

Safety is important to us at WDM so all of our machines are equipped with an emergency shutoff cable that is around three sides of the machine that will immediately shut everything down when pushed or pulled.

Controls

The 310 series comes standard with variable speed control dial. Optional is the Up/Down pushbutton for the Power Bending Adjustment and a Bending Roll Position Digital Readout. Options pictured below!

Dies

Optional angle section dies to roll angles, flat bars, squares, and small round bars. Pipe, tubing and many other dies are available. *note only available on 5" and 6" top rolls.

Drive End

The 310 series comes standard with a heavy duty all gear drive for rolls. Optional is the roller chain drive for the Power Bending Adjustment and the Encoder for the Digital Readout. Options pictured below.

Workpiece Accuracy

There are many variables that can affect the accuracy and repeatability either minimally or drastically. These include, but are not limited to, the following: varying material thickness; varying material temper; uneven cross section of material, i.e. wide and narrow profile of workpiece or a workpiece with holes or cutouts; and direction of grain of material.

Many of these variables can be overcome by various means. An important element for success is a knowledgeable operator who understands the characteristics of the material being formed and the various functions of the machine. If the workpiece being formed is anything other than uniform material and cylinders, and you are unsure if your pieces can be rolled practically, please provide us with a drawing or sketch and we will be happy to evaluate it.
