Krollit Logistics and Support
Shipping 3-5 business days from Krollit warehouse for spare parts and accessories. Customer support in Italian is available for technical documentation and compatibility verification with the reference machine. Krollit has been an official distributor since 2007.
Who is the PHV 250 high-pressure hydraulic vice for?
The PHV 250 high-pressure hydraulic 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: fast and repeatable clamping for production cycles.
Not suitable for: turning cylindrical parts (self-centering chucks are needed for lathes, not milling machine vises).

Frequently Asked Questions
What does the PHV's rotary table do?
The PHV 250 mm has a 360° swivel base with a graduated scale, allowing horizontal machining at any angle without repositioning the workpiece.
The PHV is a high-pressure precision vice, suitable for series production on universal milling machines. The precise rotation allows for repeatable angular milling.
What does the 250 mm dimension indicate?
It indicates the jaw width (250 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 dimension: as a practical rule, the jaw width should be at least 70% of the workpiece dimension. For workpieces >100 mm, choose 250 mm or larger vises.
On which machine is it mounted?
It is mounted on universal milling machines, bench milling machines, and machining centers with standard DIN T-slotted tables.
Check the weight of the vice against the table's load capacity. Bernardo vises {series or "PS/KV"} are sized for professional milling machines; for small bench milling machines, lightweight models are needed (PTS 50, PGS 50).
Are the jaws replaceable?
Yes, the jaws are hardened, ground, and fully replaceable. This is a significant advantage for long-term maintenance.
The jaws are the wear point of the vice: after thousands of clamps, they can show indentations or deformations. Replacement is autonomous with the dedicated fixing screws. Krollit provides 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 vice at the end of the shift to prevent rust on ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
