Oil Pipe Straightening Machine
Multi-point laser/vision detection measures deflection at several stations, then a flexible pressure head applies point-pressure straightening.

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I do not quote a single tolerance for all incoming stock; the machine follows the straightness of the material you feed it.

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.

copper rod straightening machine
If your copper rod comes in with ovality or residual stress, expect 0.05–0.10 mm after straightening.

copper pipe straightening machine
Our copper pipe straightening machine is built for shops that move high volumes of large-diameter tube.

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

brass rod straightening machine
Point-pressure straightening uses flat or contoured anvils so brass rod and tube leave without press marks or scratches.

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.

automatic pipe straightening machine
Workpiece material, diameter, wall thickness, cross-section, length, and weight determine the pressure required. Initial deformation and target straightness determine the precision. The machine handles both.

automatic bar straightening machine
Our straightening line integrates rolling supports, anti-whip guides, and servo-driven measurement to keep the workpiece stable throughout the correction cycle.

Automatic Torsion Straightening Machine
Correct spiral twisting and diagonal bending in square and round tubes — deformation that conventional straightening presses cannot address. 65% of scrapped workpieces recovered to tolerance
View Details →
Automatic Square Tube Straightening Machine
A closed-loop hydraulic straightening system engineered specifically for square and rectangular tube profiles. Multi-point laser measurement, automatic correction cycles completed in 30 seconds to 2 minutes, and straightness control down to ±0.03mm on precision workpieces.
