Shipping 3-5 working days from Krollit warehouse for spare parts and accessories. Customer assistance in Italian available for technical documentation and compatibility verification with the reference machine. Krollit has been an official distributor since 2007.
Who is the Machine Vice KV 125 for
The KV 125 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: rapid 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 this KV 125 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, and a swivel base with a graduated scale. Professional quality for continuous use.
What does the 125 mm size indicate?
It indicates the jaw width (125 mm), the characteristic dimension of the vice. 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 rule of thumb, the jaw width should be at least 70% of the workpiece size. For workpieces >100 mm, choose 125 mm or larger vices.
Which machine is it mounted on?
It is mounted on universal milling machines, bench milling machines and machining centers with standard DIN T-slotted 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; for small bench milling machines, lightweight models are needed (PTS 50, PGS 50).
Are the jaws replaceable?
Yes, the jaws are hardened, ground, and fully 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 fastening 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.
