What is the difference between ground and fine milled racks?

1. First of all, the tooth surface treatment methods used by the grinding rack and the fine milling rack are not the same. The former uses the grinding tooth surface treatment method, and the latter uses the fine milling (milling) tooth surface treatment method.

2. The grinding rack is a grinding rack, with high strength, high wear resistance, small surface roughness, small pitch deviation, stable high-speed movement, no abnormal vibration, and can reach or even exceed the accuracy. The basic principle of grinding is to add abrasives between the grinding tool and the product workpiece, or between the product workpiece and the product workpiece, under a certain working pressure, and the abrasive in the grinding agent performs micro-cutting on the product workpiece.

3. Racks below grade 7 need to be ground and processed, and those above do not need to be ground.

4. Grinding rack drive is a high-efficiency transmission method. Generally speaking, it is used in applications with large axial force, applications with strokes greater than meters, and linear movement.

5. Naturally, the fine-milled rack is also a very good product. Several machining processes can effectively ensure that the tooth surface deformation is small and the consistency is high. As for which product to decide, it depends on the actual application requirements of the customer, because these products are all non-standard customization and can meet the special requirements of different customers (such as tooth surface material quenching and tempering, induction hardening, laser hardening, etc.).
