Centerless Lathe Turning Machine China Manufacturer

The centerless lathe turning machine, named bar peeling machine, can be used for turning the black bar into a bright bar with high surface finish and dimension. The bar peeling machine is used to make parts such as springs, bearing, gears, shaft, and thick-walled tubes. Finished diameter: 10~250mm.

Product Description

Centerless Lathe Turning Mchine:

Bar peeling stock can be later machined into finished pieces such as bearing, car springs and stabilizer bars, car steering gear rack, hydraulic cylinder, cylinder piston rod, cold forming extrusion parts, forging parts, high strength bolts, molding, the shaft. In all of these cases, it's important to have a completely smooth, defect-free continuous surface with precise dimensions. That's where the bar peeling process and Bar Peeling Machine come into play. It produces the smooth surfaces and critical dimensions for downstream parts processing.

The Main Features of Bar Peeling Machine

● High precision and durability.

● When processing the over-length bar, Bar Peeling Machine has incomparable advantages. The ordinary lathe is good at processing short bars. But there is a great restriction for ● processing long shaft. In theory, Centerless Lathe can process the bar of infinite length.

● The round bar peeling machine process not only a processing bar but also a wire rod. That the ordinary lathe can't do it.

● Fast processing speeds. Processing speed 1~12m/min, the working efficiency of Centerless Lathe is dozens of times of the ordinary lathe.

● Simple maintenance and strong practicability

● High speed to save more time cost.

● Unique design, and it is easy to operate.

● Automatic chip removal

● Automatic loading and unloading
