Press Release number: 01411SHEAR
The latest McKechnie 131-EC sheet edge de-burring machine available through Shear-Form Ltd, the sole UK representative for McKechnie International, Florida is ideal for removing burrs and scallops on a wide range of materials including mild steel, brass, galvanised steel and especially stainless steel, normally difficult to de-burr using other methods.
McKechnie 131-EC deburrer
There are usually three problems created on straight edges using a CNC punching or nibbling machine, firstly a burr left on the bottom edge, secondly pips, nibs and microjoints on the 90° outside edge, which can cause mis-alignment when used in a press brake operation and thirdly, tool deformation marks on the top edge. The McKecknie 131-EC can eliminate all these problems in one single pass at speeds up to 20m. per minute on sheet material with thicknesses ranging from 0.5 – 6.6mmm and up to 1.5m wide using the outboard support with lockable clamps, which slide out nearly 750mm from the cutting tool. The sheet length is dependent on the capability of the operator, but lengths up to 2.5m can be easily handled.
A feature of this de-burrer is that it is 10 x times faster than using manual methods and is more cost effective as it uses only one pass to de-burr a straight edge producing a better finish and a return on investment between 68-100% annually.
Other features of this machine include two easy to use knobs on top of the machine to change the material thickness, setting so that the rollers grip the material. This is only required if the thickness varies by over 0.5mm. The programmed dimensions of the part being de-burred are not changed by using this machine. It is portable and mounted on 4 x casters. thereby can be easily moved from one part of the workshop to another.
