Coil To Bar Peeling&Straightening Line
Stainless steel wire rod is decoiled and pre-straightened, then peeled using a centerless lathe and cut to a precise length. Following a final precision straightening pass through a two-roll straightener, the resulting product is a high-precision stainless steel straight bar.
Peeling machine(centerless lathe)
The peeling machine (centerless lathe) unit is a product independently developed after comparing and contrasting the advantages of similar foreign products and combining them with the production characteristics of domestic enterprises, resulting in a simplified and optimized design.
Coil to coil production line
Coil to coil production line is a serial of the machines includes payoff & straightening machine, peeling machine, clamping mechanism, pre-bending device, recoiler machine etc. through above machines, the black coil rod will be processed to bright coil rod with good surface quality
Straightening machine BS Series
A straightening machine is a device used to straighten metal profiles, bars, tubes, and wires. The straightening machine uses straightening rollers to compress the material, altering its straightness. Generally, there are two rows of straightening rollers, with varying numbers of rollers. There are also two-roller straightening machines, which rely on the angle change of two rollers (with a concave, hyperbolic shape) to straighten materials of different diameters.

Rough straightening +peeling+ precision straightening
The black bars are pre-straightened using a rough straightening machine with hydraulic protection, then processed by a peeling machine to obtain bright bars, and finally processed by a precision straightening machine to achieve higher straightness and surface finish.
Uncoil+peeling+cutting off+straightening production line
The wire rod is unwound using an uncoiler or payoff reel, then the scale is removed by a peeling machine. The wire is then cut to the required length using a cutting machine, and finally, a straightening machine is used to achieve better straightness and surface finish.
Uncoiling and Pre-straightening+Continuous Drawing and Forming+Precision Straightening+Surface Finishing
Uncoiling and Pre-straightening: The coiled raw material is unwound and preliminarily straightened to relieve internal stresses.
Continuous Drawing and Forming: Through a multi-die continuous drawing process, the material’s cross-section is reduced while its length is elongated, achieving single-pass forming.
Precision Straightening: A secondary, high-precision straightening step is performed post-drawing to ensure straightness (typically <0.30 mm/m).
Cut-to-Length: The material is automatically cut to the required length with high precision.
Surface Finishing: Polishing and/or burnishing operations are conducted to enhance surface finish (Ra <1.6 μm).
Finished Product Collection: Automatic stacking and bundling complete the full automation of the entire process workflow.
ABOUT COMPANY
Yunde only produces high-quality products. Reputation first, attentive service.
Yantai Yunde Intelligent Technology Co., Ltd. is a company specializing in the production of centerless lathes (peeling machines), straightening machines, polishing machines, and other round steel finishing equipment. Our products are used for round steel peeling, precision straightening, and polishing, and are dedicated equipment for the finishing and processing of new-generation slender shafts, bright steel (bright materials), bars, and steel pipes.
The centerless lathes and straightening and polishing machines produced by our company feature simple operation, low noise, and high processing speed. The combination of centerless lathes and straightening and polishing machines forms an automatic production line for peeling and precision straightening of long round metal parts such as slender shafts, bars, rods, discs, and steel pipes, producing high-precision bright metal materials. This is an upgraded alternative to traditional cold drawing and pickling processes, as well as the combination of conventional lathe turning and centerless (rough) grinding.
