DESCRIPTION OF MACHINE COMPONENTS4-002 Description of individual assembly componentsMultipress machine frame Illustration 4-002-031 Right frame plate2 Left frame plate3 Upper frame plate4 Star knob to determine setting for material thickness5 Automatic position indicator for workpiece thickness6 Knurled screw to set the material thickness; 1 turn = 1 mm7 Control knob to set compressed air adjustment. Lift the knob to set. Turn clockwise to increase thepressure. After the compressed air is adjusted as desired, press the knob down again to 5.5 to 6 bar.8 Compressed air gauge9 Regulating valve for setting the vertical feeding speed10 Regulating valve for setting the vertical operating speed11 Upper travel limit for the bore head; the handle is parallel – only drilling is possible.The bore head goes up only about 70 mm after the drilling process. If the handle is slanted to the front,drilling and inserting are both possible. The bore head goes completely up after the drilling process iscompleted.12 Control panel13 Regulating valve for setting the horizontal operating speed14 The nameplate which states the model, machine number, year manufactured, electric voltage,compressed air15 Guide bars for the vertical movement of the vertical bore head16 The safety depth stop prevents the unintentional drilling of the machine table even if the depthadjustment is set wrong.17 Upper support pedestal for the vertical bore head18 Lower support pedestal for the vertical bore head19 Depth stop for the vertical bore head20 Front support pedestal for the machine frameMotor support for the Multipress vertical bore head Illustration 4-002-041 Right frame plate for the motor support2 Fastening screws for the insertion die arm3 Locking pin to pivot the gearbox through 90˚4 Cover plate for motor support5 Electric motor6 Insertion die arm7 Handle to swing the insertion die arm down8 Stop for downward swing of insertion die arm9 Locking screw insertion die arm’s fixing screw10 Gearbox bolster plate, capacity to pivot 90˚11 Vertical gearbox, according to customer’s specifications12 Back gearbox cover13 Gearbox spindles into which the quick-change drill chucks are inserted14 Actuating pin for the depth control gauge15 Pneumatic valve for the depth control gauge16 Receptacle for the dust collection deviceThe star in your cabinet27
