Who is the Machine vice with wide arch FJ 125 for
The machine vice with wide arch FJ 125 is recommended for the following professional profiles:
-
Mechanical workshops and milling operators: secure clamping of parts during milling and drilling on machine tools.
-
Production departments with series processing: quick and repeatable clamping for production cycles.
Not suitable for: turning cylindrical parts (lathes require self-centering chucks, not milling machine vices).
Frequently Asked Questions
What is a wide arch vice?
The FJ 125 mm vice has a particularly wide opening between the jaws (more than double the jaw width) for large workpieces or irregular shapes.
Recommended for clamping molds, cases, large mechanical parts that would not be clamped in a standard vice. Compromise: slightly lower precision than PS/KV of the same width.
What does the 125 mm size indicate?
It indicates the width of the jaws (125 mm), the characteristic dimension of the vice. The clamping width (maximum opening) varies according to 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 parts >100 mm, choose 125 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 capacity. Bernardo vices {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 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 autonomous with dedicated fixing screws. Krollit supplies 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 parallelism check 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.
