Gear rolling machine ZH28/25 spline hobbing machine
Spline milling thread rolling machine knurling keys hydraulic
Gear hobbing machine, gear hobbing machine) is one of the most widely used in the gear processing machine tool machine tool, cutting straight teeth on gear hobbing machine can helical cylindrical gear, also can use machining worm gear sprocket hob by generating method processing straight tooth helical teeth and herringbone gear tooth cylindrical gear and worm gear processing machine tools that use the special hob can also processing spline and sprocket ordinary gear hobbing machine special tooth profile of workpiece machining accuracy for 7 ~ 6 (JB179-83), high precision gear hobbing machine is a 4 ~ 3 largest processing 15 meters in diameter
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.
