TECHNICAL DETAILS

Process description
Step 1: Manual placement of bars on the bar magazine
Step 2: Automatic feeding of the bar and sawing off the workpiece
Step 3: Robot takes the workpiece from the sawing clamp and transfers it to the clamping device of rotary transfer machine 1 (station 1)

Rotary transfer machine 1 (machining clamping 1)
Station 2: Contour milling left and right
Station 3: Contour milling top
Station 4: Slot milling (2x), drilling Ø 6.5 mm (4x)
Station 5: Drilling Ø 5 mm (4x), thread M6 (2x), slot milling 20 × 5 mm, drilling Ø 7.5 mm (2x)
Station 6: Transfer to second machine

Rotary transfer machine 2 (machining clamping 2)
Station 1: Robot takes part from station 6 of machine 1 and places it in the clamping device of the second rotary transfer machine
Station 2: Contour milling bottom
Station 3: Slot milling (2x)
Station 4: Contour milling bottom (2x)
Station 1 (again): Unloading onto conveyor belt
