Who the UMS 100 universal machine vice is for
The UMS 100 universal machine vice is recommended for the following professional profiles:
-
Mechanical workshops and millers: secure clamping of workpieces during milling and drilling on machine tools.
-
Production departments with series processing: quick and repeatable clamping for production cycles.
Not suitable for: turning cylindrical workpieces (lathes require self-centering chucks, not milling machine vises).

Frequently Asked Questions
What does the swivel jaw of the UMS do?
The UMS 100 mm has a swivel fixed jaw with prisms of different shapes, chosen according to the workpiece to be machined (cylindrical, hexagonal, irregular).
Practical for workshops that work on differently shaped workpieces: a single vice covers multiple types. The prism jaws are hardened and ground for durability.
What does the 100 mm dimension indicate?
It indicates the jaw width (100 mm), the characteristic dimension of the vice. The clamping width (maximum opening) varies depending on the model: typically 50-105 mm for PS/KV, 105-240 mm for VH/CHV.
To choose the size: as a rule of thumb, the jaw width should be at least 70% of the workpiece size. For workpieces >100 mm, choose 100 mm vices or larger.
Which machine is it mounted on?
It is mounted on universal milling machines, bench milling machines, and machining centers with tables with standard DIN T-slots.
Check the weight of the vice against the table's capacity. Bernardo vices {series or "PS/KV"} are sized for professional milling machines; smaller bench milling machines require lighter models (PTS 50, PGS 50).
Are the jaws replaceable?
Yes, the jaws are hardened, ground, and completely replaceable. This is an important advantage for long-term maintenance.
The jaws are the wear point of the vice: after thousands of clamps, they may show indentations or deformations. Replacement is autonomous with dedicated fixing screws. Krollit supplies original replacement jaws.
How is precision maintained?
Regular cleaning of guides and jaws, application of a light layer of oil on sliding parts every 50 hours of use, periodic parallelism check with a dial indicator.
Chips accumulated in the guides compromise parallelism precision. For intensive use with coolant, dry the vice at the end of the shift to prevent rust on ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
