Krollit Logistics and Support
Shipping 3-5 business 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 the VH 125 hydraulic machine vise is for
The VH 125 hydraulic machine vise is recommended for the following professional profiles:
-
Machine shops and millers: secure clamping of workpieces during milling and drilling on machine tools.
-
Production departments with series processing: rapid and repeatable clamping for production cycles.
Not suitable for: turning cylindrical parts (lathes require self-centering chucks, not milling machine vises).

Frequently Asked Questions
How does a hydraulic vise work?
The VH 125 mm vise 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 models 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 125 mm dimension indicate?
It indicates the jaw width (125 mm), the characteristic dimension of the vise. 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 pieces >100 mm, choose 125 mm vises or larger.
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 vises are particularly suitable for CNC centers where clamping repeatability is critical. The 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 vise: after thousands of clamps, they may show indentations or deformations. Replacement is autonomous using dedicated fixing screws. Krollit supplies original replacement jaws.
How is precision 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 precision. For intensive use with coolant, dry the vise at the end of the shift to prevent rust on ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
