Krollit Logistics and Support
Shipping within 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 is the VH 150 hydraulic machine vise for?
The VH 150 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 production: 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 150 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 vises 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 150 mm dimension indicate?
It indicates the jaw width (150 mm), which is 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 practical rule, the jaw width should be at least 70% of the size of the workpiece. For pieces >100 mm, choose 150 mm or larger vises.
Which machine is it mounted on?
It can be 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. Constant hydraulic force eliminates variations due to operator strength.
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 vise: after thousands of clamps, they may show indentations or deformations. Replacement is self-contained with dedicated fastening screws. Krollit provides 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 vise at the end of the shift to prevent rust on ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
