"DECKEL TYPE" Cutter grinder with 5C COLLETS

[Edwin Dirnbeck]

Every tool shop that I have worked at has had a soe deckel grinder. These were originally puchaces to grind single point cutters for the deckel
milling machine. Even tho the deckel mill was long gone the grinders are very handy . Nowdays they seem to be used for quick small cylinrical
grinding jobs. The thing that allways agravates me is the collets .They only go to about 5/8 inch and no thru hole.Now at last the chinese have
made a model that uses 5C COLLETS.If you search for U3 GRINDER, they appear. It looks like I could order one and have it delivered to ST LOUIS
for about $1000. My questions ,Has anyone used one of these and has anyone puchaced something this expensive direct from china.These are not
being sold on ebay or retail any where in USA. Some retailers are selling the NON 5C COLLET models.Thanks Edwin Dirnbeck

Northern Tool looks to have the same one in green for 629/shipped but has poor reviews & doesn't say anything abou 5c collets?

where someone stated:

Beware the U2 uses 3C collets and the U3 uses R8.

A few other points:
1. While I did see one add that claimed 5C that doesn't mean the person that wrote it knows one collet from another.
2. Even if it's 5C, if they use the threaded hole instead of the outer threads, you won't have through hole capability.
3. If items 1 and/or 2 are a problem, returning the unit to China for a refund may be a hassle.

I had thought about making up a new spindle for mine for alternate collets- but stumbled on a set of the buttress thread collets on ebay dirt cheap... never have used the darn thing, picked it out of the scrapheap as it just looked so sad laying in the mud- thankfully stumbled upon it before any critical surfaces rusted, after cleaning up, smooth as silk...1959, very well built/fitted little tiny machine

My cuttermaster uses 5c collets, pretty nice machine. And you can get them in the 1000 dollar range used. JR

While he may not own one, I recall Sir John was familiar with the Deckel type clones.

John never seemed to like these type grinders for general use.

Edwin, you mention use for cylindrical grinding small pieces, you mean turning the the collet manually?

I agree the could have a use in most every shop if equipped with 5C, round, square, hex, etc.

I would love to find a honest review about a machine like that. Watch y tube.
I bought the airless airbearing for this machine at a cleanout of a toolshop. New for 20 euros intended for grinding the helix of the endmill. It also has got a knob to lock at the 6 divisions.
Grinding the end of 2,3,6 lip endmills. What about 4 flute?!
Got it to copy the design to upgrade my single lip cutter grinder. This ciylindrical grinding relies on a collet chuck running on ballbearings. Yes turning it by hand.

About this attachment. Do not know which collets. Clearance between axle and body 0,05mm. Runout 0,05mm mesured without collets. With cheap collets who knows. Combine these 3, hohum. Relies on 2 o-rings to keep the clearance central. Axle is hardened to prevent upgrading to 4 lip grinding.
You can do better running a reamer through a block of cast iron and using a piece of ground drillrod.
I sincerly hope that this item i got from a batch of 20 pieces are leftovers because of poor quality, exchanged after complaints.
Looks the same as all the other item on the net but from the factory that uses baby blue paint

YES,turning the collet assembly manualy.Nice indexing and angle grinding a 45 degree or whatever, chamfering end mill.Relieving back end of taps if some stupid designer want a 1/4 -20 tapped hole 1 1/4 deep full thread.Real quick single point cutters. Making a bolt with a smaller size hex head or square head , not real precision but quick and fast setup. Also if you get an angled cup diamond grinding wheel for $50 ,it is great for touching up and altering carbide inserts freehand.Edwin Dirnbeck
