  3. The measurements of the duplicate keys are not correct

    Check that the depth and lateral adjustment are well executed on the machine. Check the adjustment section of the user manual. Ensure that the two keys are positioned in the same way in the vice, either using the stops with the positioner or using the end stops on the keys. The probe and the cutter have the same angle, so it is very important to always use original JMA cutter and probe parts.

  4. The sizes of the duplicate keys are not correct even though the depth adjustment has been carefully executed. there is a difference between the head and tip of the key.

    Check that the vices are flat on their slide position, there are no chips interfering with their support. Check whether the key support is correct and there are no chips on the back of the key or inside the vice making the key not rest properly. Check that the support surface of the key on the vice is correct. Heavy duty use over a long period of time may cause the vice to wear out. In this case, replace the vice. The replacement of the vice is done in pairs to ensure proper alignment.
