FEA & Stress Analysis

The CAE software SOLIDWORKS used as the method to analyze the linear static construction, stress and deformation for press brake and laser cutting machine frames. So for complicated structures, highly complex loading' s, transient modelling and combinations of the above, FEA makes sense.

Heat Treatment Processes

PREF press brake and laser cutting machine steel frames undergo annealing at over 600⁰ to relieve stress and they are built to last years of heavy use without distortion.

Mechanical Processes

Machine frames are machined with CNC machining centers with single reference fixing. This guarantees all axis parallel and the surfaces precise which provides great accuracy and long service life of the machine.
