DB-VISE-SC-01

Precision self-centring machine vise

Name: Precision self-centring machine vise
Brand: Dongben Workholding
SKU: DB-VISE-SC-01
Availability: InStock

Jaws close symmetrically, so the datum stays in the middle of the travel.

Self-centringPrecision viseHRC 58–62 jaws

A self-centring vise for milling, drilling and grinding where the part is best located about its own centre line: shafts, symmetric blocks, square bosses, small housings. Both jaws move, so the part does not shift towards the fixed jaw as the screw advances.

Used as a stand-alone workholding on a T-slotted table, or bolted onto a hydraulic tombstone or a pallet as the cheap, replaceable front end of a larger set-up.

How it is built

Really self-centring

Both jaws are driven from the same screw, so the part centre stays within 0.01 mm of the vise centre. Cheap vises move one jaw only and pretend to centre.

Hardened where it wears

Jaws are hardened to HRC 58–62 and ground; the body is not hardened, so it can be re-machined and re-pinned instead of thrown away.

Prismatic jaws for round work

For shafts and tubes, V jaws are supplied matched to the diameter band, which is far more rigid than clamping a round part between flat jaws.

Questions

Is it really self-centring, or just a synchronised screw?

Both jaws travel on a common screw thread of opposite hand, so the geometric centre of the opening stays fixed. We state the centre repeatability in the drawing; if a supplier cannot state it, the vise is only approximately centring.

Can it be used on a magnetic chuck?

No. It is bolted down through the base. For grinding, we supply a low-profile base with the bolt pattern matched to your table.

What accuracy should I expect after years of use?

Jaw parallelism is maintained by regrinding the jaws, which are replaceable and cheap. The body does not normally need rework unless it has been crashed.

Do you supply spare jaws?

Yes, one spare set is included in the crate, and further sets are catalogue items.
