Advantages of eccentric thread rolling machine

The eccentric hobbing machine has exquisite design, simple and convenient operation, and adopts precise eccentric feed to greatly improve the product precision. The products are economical and practical, and can be divided into fixed models and roll-through models, so that customers can choose the appropriate equipment models according to product requirements. Mainly aimed at small hardware shaft parts produced by automatic cars, CNC lathes and ordinary instrument lathes, the outside diameter of equipment processing is generally in the range of 2mm—10mm. For example: instruments, clocks and watches, toy motors (micro-motor shafts), computer screws, plastic hardware shafts and knurled accessories for electrical appliances, hydraulic cylinder shafts for small cylinders, confidential screws and bolts, and micro-drive shafts with straight rolling.

Product features:

1. Hobbing belongs to plastic deformation, which is different from automatic lathe and other cutting processes, and there is no iron filings;

2. The strength and hardness of the rolled thread surface can be improved due to cold work hardening;

3. Surface roughness is less than that of turning, milling and grinding;

4. The verticality and concentricity of the processed products are better than those of the products machined by two-axis hobbing, and the accuracy is also higher;

5. High material utilization rate; The productivity is doubled than that of cutting, and it is easy to realize automation;

6. The rolling die has a long service life. However, rolling thread requires that the hardness of workpiece material should not exceed HRC40；;

7. It requires high dimensional accuracy of the blank (only when the verticality and accuracy of the blank itself are good can high-precision products be produced by the three-axis hobbing machine);

8. The precision and hardness of the rolling die are also high, and it is difficult to manufacture the die;

9. It is not suitable for rolling threads with asymmetrical teeth.
