How to Choose the Right Carbide Guide Wheel for Wire Drawing Machines？

In the metal wire drawing process, the carbide guide wheel is a key component of the wire drawing machine, and its performance directly affects the quality and efficiency of wire drawing. Choosing the right carbide guide wheel needs to be considered from various aspects.

Hardness and wear resistance are the first indicators. The hardness of the carbide guide wheel is usually measured by HRA (Rockwell hardness), generally speaking, HRA 89 - 93 guide wheel, can effectively deal with the friction of the metal wire, to extend the service life. Grades preferred YG6, YG8 and other tungsten and cobalt tungsten carbide (WC-Co), hardness of 86 ~ 93HRA, wear resistance is more than 10 times that of steel guide wheel. Specific grade selection can also contact Jinxin's experts to help you answer.

In addition, the composition of the cemented carbide should also be considered. Different ratios of WC (tungsten carbide) and Co (cobalt) content will make a difference in the toughness and hardness of the guide wheel. When machining tough metal wires, a guide wheel with a slightly higher cobalt content can be selected to enhance its impact resistance.

At the same time, the size of the guide wheel specifications need to be matched with the wire drawing machine. Including the diameter, width and groove of the guide wheel and other parameters, according to the specifications of the wire, wire drawing machine structure and process requirements to determine. The groove design should ensure the stable passage of the wire, reduce slippage and wear. v-type groove (90 ° ~ 120 °) for coarse wire, U-type / R-type groove for precision fine wire.
