Universal Cutter Grinder
Some of the modifications to the typical asian Deckel SO clone...
- Changed out the stock motor for a Consew CS1000 (same as on my
- added the thumb screw stop to allow any angle
- made holders to fit the 3/4" R-8 collet
- used the old Iguaging DRO had laying around (have new standard SPC
type scale/head that will replace it). Ok for this application since
it's reset a lot anyway.
I added a plate that locks to the
spindle just behind the wheel. This drives the slide for the DRO. The
DRO head mounts to the body; the display is mounted on standoffs and
- cut the enclosure back for added clearance of the work head
- milled the top of the spindle down for clearance from the wheel so as
bigger angles of the work head assembly
- added an additional stop screw for tilting in the other direction
- added a 12V transformer to allow normal MR16 LED lamps
- fabbed a better flute guide for grinding flutes using a small
indicator holder - see
The little plate with the pin in it sets the collet adapters to 0
The wheel is a weird 15A9 Borazon (I use mostly HSS in the shop). Have
some Borazon dish and diamonds too. I like metal wheels...
Have the mill and drill attachement - have yet to mod those...
This thing's pretty cool once you get used to it....
Consew Motor upgrade:
Variable speed is
great for various grinding things I do:
I was able to just
fit the pot, stop switch and Consew Display PCB in a small Rad Shack
Since I had to add
a filter/frame I figured I'd put the mains switch there:
I was able to
stuff the Motor and Driver in the cavity:

Flute Guide for Endmill Grinding
The funky screwdriver-like thing they supply for use as a flute guide
leaves much to be desired. I wanted something that was easy to
position, and allowed a small adjustment for the secondary relief.
The photo below shows the stock flute guide and the one I designed.
Used one of the small
indicator holders from LMS . I replaced the stock thumbwheel with
one I had on the knurling tool I replaced a while back (the stock
knuring tool knob is a bit big for use near the chuck on the lathe),
gives a bit more torque.
The point holder is threaded so i can easily back it off after I grind
the primary side relief. I used the original indicator holder's
for locking the point thread.
