Who uses the KV 150 machine vice and for what
The KV 150 machine vice is a professional-grade vice distributed by Krollit.
Its place in the Bernardo range
The Bernardo KV 150 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 performance levels: to choose the right machine for your use case, you can consult the Bernardo catalog on Krollit or contact customer support for assistance with selection.
Krollit logistics and support
Shipping within 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 KV 150 machine vice for
The KV 150 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 production: rapid and repeatable clamping for production cycles.
Not suitable for: turning cylindrical workpieces (lathes require self-centering chucks, not milling vices).
Frequently asked questions
What is this KV 150 mm vice used for?
It is used for clamping workpieces during milling, drilling or planing operations on machine tools.
Bernardo KV vices have precision ground guides, hardened and replaceable jaws, a swivel base with a graduated scale. Professional quality for continuous use.
What does the 150 mm size indicate?
It indicates the jaw width (150 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 size of the workpiece. For workpieces >100 mm, choose 150 mm or larger vices.
Which machine is it mounted on?
It is mounted on universal milling machines, bench milling machines and machining centers with tables with standard DIN T-slots.
Check the weight of the vice against the table's load capacity. Bernardo {series or "PS/KV"} vices are sized for professional milling machines; for small bench milling machines, lightweight models (PTS 50, PGS 50) are needed.
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 parallelism check with a dial indicator.
Accumulated chips in the guides compromise parallelism accuracy. For intensive use with coolant, dry the vice at the end of the shift to prevent rust on the ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
