The PS 75 precision machine vice is a professional vice distributed by Krollit.
Its place in the Bernardo range
The Bernardo PS 75 precision machine vice is part of the Bernardo vice range, distributed in Italy by Krollit since 2007. The Bernardo range includes models of various categories and performances: to choose the right machine for your use case, you can consult the Bernardo catalogue on Krollit or contact customer support for selection assistance.
Krollit logistics and support
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 PS 75 precision machine vice for
The PS 75 precision 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: fast and repeatable clamping for production cycles.
Not suitable for: turning cylindrical workpieces (lathes require self-centring chucks, not milling machine vices).
Frequently asked questions
What is this PS 75 mm vice used for?
It is used for clamping workpieces during milling, drilling or planing operations on machine tools.
Bernardo PS vices have precision ground guides, hardened and replaceable jaws, and a swivel base with a graduated scale. Professional quality for continuous use.
What does the 75 mm size indicate?
It indicates the jaw width (75 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 workpiece size. For workpieces >100 mm, choose vices 75 mm or larger.
Which machine is it mounted on?
It is mounted on universal milling machines, bench milling machines and machining centres with standard DIN T-slot tables.
Check the weight of the vice against the table's capacity. Bernardo {series or "PS/KV"} vices are sized for professional milling machines; small bench milling machines require lighter models (PTS 50, PGS 50).
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 vice: after thousands of clamps, they may show indentations or deformations. Replacement is independent using the dedicated fixing screws. Krollit supplies original replacement jaws.
How is accuracy 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 accuracy. 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.
