Product Description

In mechanical transmission systems, people use guide rollers to change the direction of transmission movement and ensure its smooth operation. They are usually composed of spacers, guide roller shafts, guide rollers, glands, and bearings. Guide rollers play an important role in working environments such as mining equipment and construction machinery. So in general, guide rollers can guide, adjust, and support moving parts to ensure that moving parts run along a predetermined trajectory, reduce friction, vibration, and offset, and may also assume tension adjustment or support functions.

Applications Of Tungsten Carbide Guide Rollers

Precision Wire Cutting Processing

In the process of using WEDM-HS, Low Speed Wire Cut, and other machine tools, the accuracy of the electrode wire path is very important. For example, in WEDM-HS equipment, the electrode wire moves repeatedly at high speed, which causes great friction loss to the guide roller. In order to withstand such high-frequency friction and vibration, the excellent physical properties of cemented carbide make it a leader in this field.

Metal rolling and wire drawing equipment

In hot rolling production lines and wire drawing equipment, metal will move repeatedly at high speed along the predetermined route through the guide roller groove, and finally achieve the processing purpose of plastic deformation of metal materials. Cemented carbide guide rollers are undoubtedly the core components of metal rolling and wire drawing equipment. Such a high temperature and high-friction working environment requires high material quality of the guide roller. During the rolling process, the pressure can reach hundreds of MPa, and the hot rolling temperature can reach 800-1200 degrees Celsius. In such an environment, the carbide guide roller can still remain stable and not deformed. While ensuring the processing accuracy, it can avoid economic losses caused by frequent equipment maintenance.

Mining and engineering machinery

Like other mining equipment parts, the guide rollers in mining and engineering machinery often act on conveyor belts, crushers, and other parts, and need to withstand severe wear from ore and sand. 24-hour non-stop operation, high load, and severe wear are particularly obvious in such a working environment. Guide rollers made of traditional materials often lead to extremely high failure rates and maintenance frequencies.

High-precision 3D printing/ laser cutting equipment

High-precision processing, hundreds of cycles of operation, and such an operating environment put higher requirements on the compressive strength and wear resistance of all its components. More and more manufacturers favor carbide guide rollers. In the process of material transportation and motion positioning, this excellent material can often avoid failures.
