Manufacturing Technology

Straighten, cut and chamfer Videx offers straightening and cut machines for both short and long cut lengths. The short cut models cut from 10mm long and up to one or two metres at speeds up to 1,000 cuts per minute. The new long cut models can cut both short and long parts with an unlimited length. The company has added an integral high-speed chamfer cutting station to its line of straightening and cut machines. The chamfers are cut dry and the chips are automatically removed from the cutting area into a waste bin, leaving the work area clean and dry.

A positive grip of the parts during cutting ensures a smooth cut face with no vibrations, as well as longer life of the chamfer carbide tips. The gripping system also allows chamfering on one side only, if required. The Videx chamfer system allows short parts to be chamfered down to 90mm long, and the chamfer length is accurate due to a positioning device that locates the bars prior to chamfering.
