MACHINE CONSTRUCTION:self-carrying construction of machine top unit, which is used for mounting of all, machining units, the indexing drum and absorbing of the machining energyThe strong machine base carries the top unit, however without absorbing machining forces. The index drum RTHV 800-240 with HIRTH-spur gear is of large dimension. The drum indexing is done hydraulically with double-swivel drive resp. oil motor, free of backlash, indexing precision +/- 0,01 mm, indexing time approx. 3,5 sec.Drum clamping during the machining. Double indexing possible.At present the machine is equipped/tooled up for the machining of small eccentric shafts with a length of approx. 225 mmChucking diameter 22,5/ 32,5 mmcycle time realized approx. 1 min.The machine is equipped with an automatic loading and off-loading attachment FELSOMAT. The machine has worked on a VW-drive shaft-no. 030 145424/G 40 resp. no. 030 145434/G 60.The loading/offloading unit consists of:-feeding conveyor-delivery conveyor-linear unit-swiveling unit-short stroke slide-parallel gripper tong-swivel moduleclamping stroke of gripper tong approx. 5 mmradial stroke of gripper unit for pick-up resp. off-loading of work piece and/or loading of work piece into the chucksapprox. 250 mmFor pick-up of the work pieces, the index drum is equipped with hydraulic operated 2-jaw-chucks make RÖHM No. OW-414029.Chuck-diameter 300 mmpiston stroke 58 mmstroke per jaw 33,5 mmoperating pressure 40 bartotal clamping force 2800 DaNwork pieces are automatically loaded into the chucks through the gripper system. The work pieces are clamped in vertical position.The various machining stations are equipped with different machining units on different positions.Position 1 : vertical machining unit, operating from top to bottomPosition 2 : radial unit, 90 degree angle positionPosition 3 : vertical machining unit, operating from bottom to topThe position and kind of available machining unit can be seen from the enclosed arrangement drawing.The various units are suitable for:-turning and drilling operation-deep hole drilling operation-thread cutting operation-CNC turning operationMachining unit PEHT 60/140: Station 1.1, 1.3, 8.1 and 8.3Station 1.1 and 8.1 with additional centrifugal ring, 1.3, 8.1 and 8.3 additional with labyrinth ventilation, spindle sealing.Station 8.3 with centrifugal ring, adapter for center and center make RÖHM.spindle speeds approx. 700 - 2000 rpmdrive capacity approx. 4 kWStation 1.1 and 1.3 additional with tool breakage control.Turning and drilling unit PEHT 80/180 on station 2.1 and 2.3pick-up-diameter of adjustable sleeve 36 mmwork stroke 180 mmspindle speeds upto max. 3200 rpmdrive capacity 4 kWUnits equipped with internal coolant supply, centrifugal ring and station 2.1 additional with intermediate stop.Quill unit PEMT 25/180 MC - station 2.2 and 3.2:with CNC control SIEMENS 810With these units, drilling; reaming and sinking operations are possible.
