Diprofile machine

[Tractor manParticipant @tractorman]

Hi all.
Having moved home and workshop I’m still not making anything yet. But I did pick up a diprofile classic machine file today and wondered if anyone has any experience with this tool. It’s complete and operational but I could do with a manual or instructions on how to set the stroke etc. Hoping it will be useful for filing small parts. Cheers mick

If you do a search on Google for "diprofil manual" you will find just what you need.

Hi Mike thanks for the tip. I have found the uk supplier and hopefully they will be able to provide a manual. They have the full range of files and hones so I will buy some in and report back on the performance. New machines cost almost ?900 so my barain from the used tool dealer is well worth it. Mick

I have put a couple of photos of the diprofile machine in my albums. I stripped and cleaned it last night and dug out my flexible drive dentist drill to see if it would fit the coupling on the diprofile. Success! It runs like a mini sewing machine, driving a file or hone back and forth. The kit also includes a mini saw blade holder and a carbide scraper which achieves the same results as hand scraping but in miniature and without the elbow grease. Looking forward to playing with it now. Mick

There is one on ebay from Bulgaria at 238 plus 95 postage! Wow I paid 40 pounds for mine. True it needed servicing and some new files but it’s the bargain of the year.

Hi I have four diprofil hand pieces. they are a smaller version and fit my pendent motor flexible shaft. Three have a set filing stroke length 0.5mm 1mm and 1.5mm the other has an adjustable side to side sweeping action. All came from Febay at less than £40 each. I have found they work best for me with ceramic stones and small Diamond files run at about 10,000 rpm

Hi Adam. Those sound like the mini lapping heads which are much smaller than the classic machine. They are still excellent pieces of kit. The classic has a stroke of between 1 and 6mm so quite a bit of grunt for filing.
I have put some more pics in my album to show the accessories and some examples of work from the manual. Mick

What? no pics of the innards when you stripped it? What mechanism does it use to produce the reciprocating motion and is there any vibration damping? Seems like a simple enough project.

Quite a usefull tool I also have one' but it's air driven from my compressor as opposed to a mechanical drive, not sure which is the best. probably not a lot in it.

[Tractor manParticipant @tractorman]

I didon’t think to take ant exploded views. The mechanism is a simple shaft driven eccentric running on bearings which drives a connecting rod mounted on a ball joint to the reciprocating head. No vibration damping evident in the mechanism.
The work head is mounted on a sleeve so that it can rotate freely whilst being operated to allow the user to control the direction of the file or hone keeping it in flat contact with the work.mick

We used them in the toolroom at Ferranti's some years ago on both plastic injection moulding tools and diecasting dies making smaller items.

From memory for fine finishing including lapping, polishing, removing blemishes, increasing the draw in dies etc.
