When it comes to relieving internal stress in materials, the material straightening machine stands out as a specialized equipment. However, selecting the appropriate machine entails understanding the distinctions between precision straightening machines and their ordinary counterparts. Let’s delve into the nuances to guide your decision effectively.

Differences in External Structure

Ordinary Straightening Machines: Ordinary straightening machines typically feature 7 support rollers, comprising 3 upper and 4 lower ones.

Precision Straightening Machines: In contrast, precision straightening machines boast either 15 or 19 support rollers, with configurations of 7 upper and 8 lower rollers, or 9 upper and 10 lower ones, respectively. The abundance of support rollers in precision machines sets them apart significantly.

Variations in Component Manufacturing

Roller Manufacturing: While both types are referred to as straightening machines, their component manufacturing processes differ substantially. In ordinary straightening machines, the roller manufacturing process involves turning, milling, keyway machining, high-frequency treatment, concentric grinding, hard chrome plating, and surface polishing. On the other hand, precision straightening machines undergo a more intricate process, including steps such as material conditioning, rough turning, milling, keyway machining, high-frequency treatment, rough grinding of the outer circle, hard chrome plating, and finish grinding of the outer circle.

Wall Panel Processing: Ordinary straightening machines utilize cast iron panels processed in batches on milling machines, whereas precision straightening machines employ CNC machined 45# steel plates post quenching and tempering.

Divergence in Straightening Effects

Ordinary Machines: Ordinary straightening machines rely on scale references and manual adjustment of coarse teeth handwheels, relying heavily on the operator’s tactile sense.

Precision Machines: In contrast, precision straightening machines utilize precision dial indicators and spring-loaded pressure adjustment devices on all four corners of the cover plate for meticulous adjustment. The profusion of rollers in precision machines facilitates aggressive rolling at the front end to eradicate internal stress, followed by gradual straightening at the rear end, culminating in superior straightening effects with reduced rebound tendencies.

Surface Impact on Straightened Materials

Ordinary Machines: Ordinary straightening machines often lack variable frequency drives, leading to surface indentations on materials due to abrupt starts and stops during automated online production.

Precision Machines: Precision straightening machines come equipped with variable frequency speed control, ensuring buffered start and stop times to mitigate damage to straightened materials.

In essence, the choice between ordinary and precision straightening machines hinges on the precision requirements of your products. Precision machines excel in applications demanding meticulous straightening, while ordinary machines suffice for products with lower precision requisites. Moreover, the disparities in processing, structure, and materials contribute to a substantial variance in pricing between the two types. Hence, it’s imperative for customers to align their selection with the production needs accordingly.
