Hi,
Was having some trouble with my old home made vise, so I decided to buy a new one.
I have a Seig SX2.7 milling machine, and a 4" (100mm) seemed a little too big, and at 16kg, too heavy.
I found an 80mm (3"+a bit) and bought it.
Unboxing seems to be the rage for electronic gear, so thought I would "unbox my vise"
Took 16 days to arrive from East Coast USA to Melbourne Australia - quite a tour of the world:
Box seemed to have survived the journey OK, but was a little mashed up.
Inside, the expected accessories were there:
A booklet that identified it as a "QM16 ACCU_LOCK PRECISION MACHINE VISE".
A handle, and several sets of bolts, nuts, and keys.
Only a minimum amount of foam was used:
There was no way this foam was going to survive intact.
Fortunately there seems to be no damage to the contents.
A better look at the vise:
The vise appears reasonably well made.
It was rather grimy, and the bottom needed a little cleaning up.
The handle fits on a hex shaft - unfortunately it is NOT a standard size at about 11.5mm.
Other parts:
It comes with a swivel base. This seems to be a lower quality casting, but OK. I'm not likely to use it too much. Vise is held onto base with 2 bots as seen already attached to the base.
A pair of ground back bolts are supplied to use as Tee nuts.
Also supplied are a pair of keys and screws.
My mill has 12mm slots, and the supplied accessories fit perfectly.
A little weakness:
As identified by "Eddie the Grouch", a problem with these vises is that the shoulder on the screw isn't large enough to support the whole back of the bearing. This puts quite a strain on the bearing shell and it will eventually break.
At some point I'll fit an extra washer or two to provide some extra support.
I have NOT checked the bearing type and size, nor have I looked for the hemi-sphere needed to operate properly. These are a job for another time - rainy day maybe.
After a little cleaning up thought I would do some basic measurements:
- As best as I could measure the base was flat to less than 0.025mm (0.001").
- With the keys fitted and the vise dropped into a slot, the vise was square to within 0.05mm (0.002"). This made it very easy to tram.
- The fixed jaw does not seem to be very square with the base. This may be due to home I was trying to measure it, or maybe it isn't very square.
- In going from no load to tightly clamping something, the fixed jaw moves by less than 0.01mm (0.0004"). My old vise had 0.2mm movement so it is quite an improvement.
Overall I'm very happy with it, and it looks great on my mill:
