Z28-35 Hydraulic Radial Knurling Milling Thread Spline Rolling Machine

Spline milling thread rolling machine knurling keys hydraulic 

A mass of screws can be precisely made by thread rolling machines with thread rolling dies.   "Cold forming" is the most appropriate description of thread rolling progress. Place a round material blank in the between of thread rolling dies.  The die thread penetrates the blank surface to form the thread roots and displaces material outward form the crest.  This is the basic theory for thread rolling.

Spline rolling is the fastest and most economical method of producing involute tooth forms..This series of equipment help the customer to select cold spline rolling and rolling accurately according to the parameters of an involute spline.


High Precision Rolling Machines design of high precision two and three dies spline and thread rolling machines. A newly designed hydraulic system allows a shorter cycle time and less maintenance. The combination of all these factors allows a high repeatable production combined with a longer die life.






Designed for the thread rolling of standard screws, bicycle parts, automobile parts, small household electric appliances and various and various machinery parts.

The precise worm shaft and worm gear: Keep steady transmission, and the accuracy of thread profile.

Precise transmission grinding type gear shape: Noise-free, durable, transmission operates precisely, and no extra space when transmission.Dove tail-type slide: assuring that jumping, vibration, and wear will not happen during rolling process.

This machine adopts eccentricity feeding: Featuring easy operation and smart design.
