3How themachine works3.1Adjustment and fine tuning3.2.2 Cutting OP-WH.P and OP-WY.P keys3.1.1 Adjusting the cutting depthCalibration should be carried out every time the tracerpoint and milling cutter are changed.To adjust the tracer point and milling cutter, proceed asfollows:1 Insert the tracer point and the milling cutter into thecorresponding chucks, pushing them right in untilthey will go no further. In order to carry out the minimum movements in the adjustment operation, tighten the chuck so that the tracer point and milling cutterare fixed into position.2 Put two similar keys into the machine clamps tomake sure the tools are properly fixed into place.3 Remove the flexibility from the tracer point (turn theknob on the left). Rest the tracer point and themilling cutter on the keys located in the clamps.When you do this, the two red lights should comeon. If only one red light comes on, carry out adjustments with the part above the tracer point, untilboth red lights come on.3.1.2 Flexibility of the tracer pointThe tracer point can be located underneath theadjustment position, as this tool is equipped with aflexible movement. If the tracer point is in this position,during the cutting operation you gently insert the tracerpoint into each hole (perforation) on the original key,thereby facilitating the machining work of the millingcutter on the blank, without any vibration or movementtaking place, and therefore ensuring a really precisecopy of the key.The 2nd speed is used for hard metal tools.3.2 Cutting keys with the standard clampTo work safely when cutting keys, you must adhere to thefollowing rules:Work with dry hands.Make sure that the machine is earthed.Use protection goggles.The machine must be switched off and the red motorswitch off when securing and releasing the keys.3.2.1 Cutting SEA-1 keysPut the milling cutter and tracer points into place, F-1 / P-1(side) and F-3 / P-3 (blade grooves).The side dimples F-1 / P-1 are cut normally. But the groovesF-3 / P-3 have to be cut as follows:Place them at the same height using the adjustment lights,removing the flexibility from the tracer point. Thenlower the tracer point by five points (turn the tracerpoint adjuster to the right). Note: the five points youlower the tracer point depend on the pressure exertedby the operator, if you exert a lot of pressure the fivepoints will be increased. Insert into the groove. Lock themilling cutter and the tracer point in the groove with thelever on the right. Raise the tracer point a little so that itdoes not drag the key. Enter by the middle of the groovewithout touching the sides and enter from the right inthe second pass and exit from the left without exertingany pressure, just resting the tracer point. 1st speed. Seefigure 10Fit the keys tightly into the clamps against the bar insertedinto the groove in the clamp. Use tool no. 11 andsecure them at the same height using the adjustmentlights, removing the flexibility from the tracer point.Then lower the tracer point by five points (turn thetracer point adjuster to the right). Note: the five pointsyou lower the tracer point depends on the pressureexerted by the operator. If you exert a lot of force thefive points will be increased. Insert the tracer point andmilling cutter into the groove. Lock the milling cutterand the tracer point into the groove with the lever onthe right. Raise the tracer point a little, so as not todrag the key. It is best to carry out a roughing pass firstfollowed by another finishing pass, following the wholeprofile of the shape of the key. Machining is carried outin a downward direction, from the tip of the key to thehead. Use the side spring. 1st speed. See figure 113.2.3 ME-3.P and ME-4.P keysUse the AD-MM adapter (see drawing), tracer point and millingcutter no. 11. Position the adapter on the clamp. Position thetwo keys and place them at the same height. Place the tip upagainst the adapter and carry out the adjustment with thelights. Insert into the groove. Remove the flexibility from thetracer point and lock the milling cutter and tracer point in thegroove with the right-hand lever. Raise the tracer point a littleso that it does not drag the key. Make the first cut. Given thatthe keys are reversible, only turn the blank. Release the clamps,remove the key and put it back the other way around. Lockthe clamps and make the second cut.Use the side spring. 1st speed. See figure 123.2.4 JIS-4P keyUse the AD-MJ adapter (see drawing), tracer point andmilling cutter no. 11. Position the adapter on the clamp.Position the two keys, placing them up against the rotatingplate. Adjust the cutting depth of the two keys, removethe flexibility from the tracer point and make the first cut.Turn the keys to the other side of the adapter, carry out theprevious key positioning process and finish with the secondcut.See figure 133.2.5 Type FO-6P key (Ford)Place the adapters on the clamp. Use tool no. 22. Whenpositioning the key, make sure that it is really flat, so thatthe two cuts come out the same. Carry out adjustmentsusing the lights. Remove the flexibility from the tracerpoint. Insert the tracer point into the groove of one letter,lock the right with the right-hand lever and raise the tracerpoint slightly so that it does not touch the adapter and makethe cut. 1st speed.Reading the code of the original key:The original key has 6 cutting positions. For a correctreading to be made, you have to take the key in yourleft hand, with the blade of the key to the right of theblack plastic head, as shown in Figure no. 14.The 6 positions for cutting the key correspond to combinationsof 4 different heights that are indicated andnumbered below:11English
