Who the Quick-Release Vise SP 55 is for
The quick-release vise SP 55 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 serial processing: fast and repeatable clamping for production cycles.
Not suitable for: turning cylindrical parts (lathes require self-centering chucks, not milling machine vises).
Frequently Asked Questions
What is a quick-release vise?
The SP 55 mm quick-release vise is a lever-operated quick-clamping vise, for fast operations that do not require maximum precision.
Practical for small series production, installations, and tests. It does not replace a precision vise for milling, but it is recommended where clamping speed is needed.
What does the 55 mm dimension indicate?
It indicates the jaw width (55 mm), the characteristic dimension of the vise. The clamping width (maximum opening) varies by model: typically 50-105 mm for PS/KV, 105-240 mm for VH/CHV.
To choose the size: as a practical rule, the jaw width should be at least 70% of the workpiece size. For workpieces >100 mm, choose 55 mm or larger vises.
On which machine can it be mounted?
It can be mounted on universal milling machines, bench milling machines, and machining centers with standard DIN T-slot tables.
Check the weight of the vise against the table's capacity. Bernardo vises {series or "PS/KV"} are sized for professional milling machines; for small bench milling machines, lighter 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 vise: after thousands of clamping operations, they may show indentations or deformations. Replacement is self-sufficient 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 checking of parallelism with a dial indicator.
Accumulated chips in the guides compromise parallelism precision. For intensive use with coolant, dry the vise at the end of the shift to prevent rust on ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
