metal straightening press
I do not quote a single tolerance for all incoming stock; the machine follows the straightness of the material you feed it.

Our Products
Hydraulic straightening machines engineered for precision, reliability, and production efficiency.
iron rod straightener
If your incoming rod stock is already straight within 0.3 mm per meter, you can chase tighter output. If it starts with 2 mm of runout, the first pass will correct most of it, not erase it in one shot.

cnc shaft straightening machine
Three to five laser or contact probes scan each shaft before and after every correction.

axle straightening machine
We see this machine used most often on high-volume lines for passenger-vehicle half-shafts and commercial truck axle shafts, where one operator oversees several cells and scrap from a missed spring-back erases a shift's margin.

automatic tube straightening machine
This machine corrects bend without collapsing the cross-section — the problem that separates tube straightening from bar straightening. It handles thin-wall tube that would ovalize in a conventional press and thick-wall tube that needs serious force without cracking the material.

automatic shaft straightening machine
Every shaft brings its own runout signature. A 1,200 mm drive shaft with 0.8 mm initial TIR in the middle needs a different correction strategy than a 200 mm motor shaft with 0.05 mm TIR.
