FEA & Stress Analysis

Stress Analysis & Finite Element Analysis

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

Why KRRASS NC Press Brake?

NC Back Gauge System

One of the most important factor for bending capacity is the design of back gauge and stability. Quality cutting is possible with perfect product,stabilty and precision back gauge. The high speed ballscrew back gauge system movement is also supported with linear guides, which helps the back gauge achieve long life, greater sensitivity and strengthens against any collisions.
