Its place in the Bernardo range
The Bernardo Wide-Arch Machine Vice FJ 150 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 catalog on Krollit or contact customer support for selection assistance.
Krollit logistics and support
Shipping 3-5 business days from Krollit warehouse for spare parts and accessories. Customer assistance 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 Wide-Arch Machine Vice FJ 150 for?
The wide-arch machine vice fj 150 is recommended for the following professional profiles:
-
Mechanical workshops and milling operators: secure clamping of workpieces during milling and drilling on machine tools.
-
Production departments with serial processing: fast 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 a wide-arch vice?
The FJ 150 mm vice has a particularly wide jaw opening (more than double the jaw width) for large workpieces or irregular shapes.
Recommended for clamping molds, casings, large mechanical parts that would not be clamped in a standard vice. Compromise: slightly less precision than a PS/KV of the same width.
What does the 150 mm dimension 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 workpiece size. For pieces >100 mm, choose 150 mm vices or larger.
Which machine is it mounted on?
It is mounted on universal milling machines, bench milling machines, and machining centers with standard DIN T-slot tables.
Check the weight of the vice against the table's load capacity. Bernardo vices {series or "PS/KV"} are sized for professional milling machines; lighter models are needed for small bench milling machines (PTS 50, PGS 50).
Are the jaws replaceable?
Yes, the jaws are hardened, ground, and completely replaceable. This is a significant 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 autonomous with the 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.
Accumulated chips 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.
