    FP2NC z axis shudder and fault when using rapids

    Sounds like you are provoking the Z axis overload clutch. Clutch might need adjustment or you have developed higher than normal friction. Ways or lube could be an issue. Could try cycling the axis over full travel while cycling the lube pump. Should feel lube oil on the inside faces of the...

    FP2NC z axis shudder and fault when using rapids

    When you say “it faults” exactly are the indications? Error code, E stop? Does it make any noise, maybe a sort of machine gun sound? Does it happen going both directions(up/down) ? Cheers Ross

    How to diagnose rapid traverse on an FP2?

    There is some confusion with the way the pin is installed,perhaps the previous owner got it wrong. Pins should have a head at one end. The pin should be installed in the small hole of the outer sleeve, and retained by the clip. The large hole (opposite) is there to make removal of a shorn pin...

    FP2NC z axis shudder and fault when using rapids

    I would check the max voltage that you get on the servo control input when doing rapids. (Input X31:1 and X31:2) My guess is that the Z servo is running too fast, likely being fed more than 10v at rapid. As a quick check, try swapping the Z axis cards ( both amplifier and regulator) from the...

    Precision Boring Head

    Nice collection, don’t see a corner milling attachment or angle milling head. Do you have the high frequency grinding spindle units with the high frequency power supply to go with that grinding head? Having to have that “Uber rare” riser is reason enough to go for the FP 2 let alone the higher...

    Looking to move into an industrial machine, and looking for the right machine for the job. Seeking people smarter than I to help guide me.

    Don’t have specific suggestions for a machine, my work requirements and choice is quite different. However you need to put your shop in order ahead of any machine choice. Don’t short change the power. If this is a real business and not a hobby then you need real power. If your business grows...

    Compound Rest Repair

    Would not be putting enough heat into that casting to braze repair that broken section. Think your idea of inserting a steel plate and holding with recessed flat head Allen’s is a good solution. Fit the plate somewhat proud of the base surface and finish the entire top on the surface grinder...

    Fixturing an Optical Extender Tube on a Lathe

    Turn a spud that fits with clearance on the 12mm thread minor diameter. Face flat, make long enough to bottom on the inner step. Drill and tap for 5/16 or 1/4 thread. Slide part on spud use bolt and washer to hold part against inner shoulder. Tighten bolt lightly, tap part around till it runs...

    Precision Boring Head

    I don’t think changing the driven gear on the boring head requires changing any other gears. That driven gear is afaik mounted at the end of an input shaft that drives the head spindle and feed. The gear does not mesh with any other gear other than the drive gear in the “Y” slide, so no mesh...

    Be prepared to pay! Not seen that FP1 riser sell for cheap! If your need is time sensitive Singer is likely your best chance! Cheers Ross

    So I just bought a Ruhla FUW 250/IV

    I would look into repairing the original setup. Most likely some issues with the power supply for the DC motors. Staying original has advantage that the motors are integrated and already fit. DC motors also provide better stall power than AC. Likely will have better power than a conversion, plus...

    Precision Boring Head

    Think the answer is that head was originally purchased from the factory as part of an order for an FP1 that included that precision boring head. Note tag is stamped with the FP 1’s serial number. In all cases that anyone has ever seen ,save one instance, FP1’s all require the 2125-100 (FP1)...

    Deckel FP2 Quill Stiff

    A lap will increase the ID is the quill if it has any effect at all, so you need a way to compensate for the change. Obvious solution is oversize rolling elements. Shops that do this work on a regular basis have stocks of stepped sized needles allowing test assembly to verify final assembly. On...

    Deckel FP2 Quill Stiff

    Replacing the spindle bearings may be problematic. Deckel spindles do not have replaceable inner or outer races for the spindles. Needles run directly on the ground surface of the spindle (OD) and the ground surface of the quill (ID). To account for manufacturing tolerances the clearance between...

    Deckel FP3NC inspection / setup

    Can’t really tell about the way gauling as the area of worst effect is always covered be the vertical slide is all the way up or down. The problem can be nullified, have done so on your machines big brother (FP4NC). Do a search if you want more info. Doing a retrofit here is not like converting...

    Dialog 4 upgrade

    Remember that programs in “Dialog” appear on screen left to right. The < > keys allow paging from block to block. There are also instances where you need to select to the right or left such as in mode 13 when setting for the file transfer values. Also don’t forget that in parameter programming...
