Automated unloading by metallic conveyor belt
Modern CNC control technology is used by U-Jin Tech Corp both for automatic material transport and in cases where high accuracy is required. Due to the position measuring devices known from CNC milling machines, the length tolerance of the components can be maintained more accurately than with conventional hydraulic machines. It is even possible to bring the spindle to a standstill in a given position so that the two eyes of a drive shaft can be positioned at an angle to each other.
The two spindles of these machines are driven by servo motors that allow the angular position of their motor shaft to be controlled, as well as the speed of rotation and acceleration, since they are equipped with position sensors. If the spindles are controlled in the same way as CNC-controlled servo motors, angular accuracies of ±0.5° can be achieved, e.g. at both ends of a cardan shaft.
Angularly aligned Ends of a propshaft
Friction welded universal joints
Heavy Duty driveshaft for high-torque transmission
The machine series is primarily designed for the friction welding of cardan shafts in the automotive industry, which is expressed by the letter P for propshaft.
CNC 12DF-D Double Spindle Machine with 12 t Force
Friction welded small diameter drive shaft
Friction welded large diameter drive shaft
CNC 12DF-D friction welding machine for drive shafts
This machine series is primarily designed for the friction welding of axially symmetrical drive shafts in automotive engineering, which is expressed by the letter D for driveshaft. With these components, exact length tolerances have to be maintained, but the end pieces do not have to be aligned at the a specific angle to each other.
