Who is the hydraulic vice for MSB 320 V / VL / VC for
The hydraulic vice for MSB 320 V / VL / VC 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-centring chucks, not milling machine vices).
Frequently Asked Questions
How does a hydraulic vice work?
The 320 mm vice uses a hydraulic cylinder inserted into the screw with a pressure multiplier, ensuring constant clamping without operator fatigue.
The hydraulic system allows clamping force up to 5500 kg on CHV with little manual effort. For series production and CNC centres, it is the standard choice to reduce operator fatigue and improve repeatability.
What does the 320 mm size indicate?
It indicates the jaw width (320 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 size of the workpiece. For workpieces >100 mm, choose 320 mm or larger vices.
Which machine does it mount on?
It mounts on universal milling machines and vertical CNC machining centres with standard DIN T-slot tables.
Hydraulic vices are particularly suitable for CNC centres where clamping repeatability is critical. Constant hydraulic force eliminates variations due to operator force.
Are the jaws replaceable?
Yes, the jaws are hardened, ground, and fully 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 accuracy maintained?
Regular cleaning of guides and jaws, application of a light oil film on sliding parts every 50 hours of use, periodic checking of parallelism with a dial indicator.
Chips accumulated in the guides compromise parallelism accuracy. For intensive use with coolant, dry the vice at the end of the shift to prevent rust on the ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
