Shipping 3-5 working days from Krollit warehouse for spare parts and accessories. Customer support in Italian available for technical documentation and compatibility verification with the reference machine. Krollit has been an official distributor since 2007.
Who is the VH 100 hydraulic machine vice for?
The VH 100 hydraulic 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 vices).

Frequently asked questions
How does a hydraulic vice work?
The VH 100 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 of up to 5500 kg on CHV with little manual effort. For series production and CNC centers, it is the standard choice to reduce operator fatigue and improve repeatability.
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 practical rule, the jaw width should be at least 70% of the size of the workpiece. For workpieces >100 mm, choose vices of 100 mm or more.
Which machine is it mounted on?
It is mounted on universal milling machines and vertical CNC machining centers with standard DIN T-slot tables.
Hydraulic vices are particularly suitable for CNC centers where clamping repeatability is critical. Constant hydraulic force eliminates variations due to operator strength.
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 the 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 checking of parallelism 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.
