Yes, Austrian GFM Company was established in 1945, located in Stail, Austria. Since its establishment, it has been committed to the development and application of rotary forging precision forging machine, which has been widely used in various fields all over the world. Its skk series precision forging machine has been used on more than 60 automobile shafts (especially hollow shafts) in the world/KLOC-0. The hollow shaft of DCT gearbox has been successfully applied to German Volkswagen DSG and South Korea Hyundai DCT hollow shaft.

The process scheme is rotary forging and hollow forging, which has no loss of chip drilling materials, greatly reducing material loss and strengthening the structure and performance of the shaft; The process scheme is simple, with few production equipment and leading technology in the world. Short production beat; Ideal material particle flow; The material is molded, so there is no material loss and the material utilization rate is improved; Reduce mold changing time; Automation reduces downtime; Reduce the number of handlers;

Brief introduction of GFM skk precision forging press

Skk series machine tools were developed by GFM Company on the basis of its famous SX precision forging machine tool. It represents the development direction of the only rotary forging machine in GFM world. China is represented by Shanghai Xuhui Trading Co., Ltd..

Compared with the past:

The design is more compact

Longer service life

The equipment is stronger

Diversified (flexible) production capacity is stronger

Low maintenance cost

There are no basic requirements.

The principle of forging hollow shaft;

The forging die is used for high-frequency forging, the hollow blank and the mandrel rotate synchronously and move axially, the position of the forging die is controlled by CNC program, and the complex shape outside the forging and the high surface accuracy forging are forged, and the mandrel realizes the high-precision forming of the complex shape inside the hollow shaft.
