Merlin valve seat grinder and fuel injector lapping machine

[Nick Clarke 1Participant @nickclarke1]

 

 

Hi there

 Has anyone come across a machine like this before? (see photo) It has 3 crompton motors, 1 to drive the grinding head, 1 to drive the workhead and 1 to drive the lapping plate. The workhead on my example has 2 pratt burnard 5 inch scroll chucks mounted on it and swivrls on a mounting that is graduated in degrees. This assembly can bev moved longitudally along the bed via a leadscrew. the grinding head has 2 wheels (one on each end) and moves across the bed. It also has a coolant system supplied by a gearwheel type pump.

The machine is of 1970's vintage and is in perfect condition. I have a notion to convert it to another use, any ideas? the photos are scanned from the manual, I will post better ones when I get my camera fixed.

Set up refurbing fuel injectors Nick, the price they charge for a “Replacement injector” makes it viable in these recessionary times. Last saw one used 45 years ago when we used to REPAIR  things.

Many thanks, however,I wouldn’t have a clue how to start, instruction manual a bit vague in
places.

With the various drives and motions available to you I’d have thought you could have sharpened or made just about any cutters on it and given them a mirror finish to precise size on the lapping plate. Should also be able to do cylindrical grinding probably  small scale surface grinding as well.

Thanks for your suggestions, I shall have a go, as a relative newcomer to this hobby I will need to do some research into tool and cutter making
