Who uses the 2-axis precision machine vise PTS 50 and for what
The 2-axis precision machine vise PTS 50 is a professional-grade vise distributed by Krollit.
Its place in the Bernardo range
The Bernardo 2-axis precision machine vise PTS 50 is part of the Bernardo vise 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 in selection.
Krollit logistics and support
Shipping 3-5 business 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 2-axis precision machine vise PTS 50 for
The 2-axis precision machine vise PTS 50 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: rapid and repeatable clamping for production cycles.
Not suitable for: turning cylindrical workpieces (lathes require self-centering chucks, not milling vises).
Frequently Asked Questions
How do you tilt a PTS vise?
The PTS 50 mm vise tilts on 2 axes (360° horizontal rotation + 90° vertical inclination) with graduated scales for angular positioning.
It allows complex angled machining (e.g., inclined holes, angular milling) without repositioning the workpiece. The double graduated scale allows for precise intermediate angles.
What does the 50 mm dimension indicate?
It indicates the jaw width (50 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 dimension: as a rule of thumb, the jaw width should be at least 70% of the workpiece size. For workpieces >100 mm, choose 50 mm vises or larger.
Which machine is it mounted on?
It is mounted on universal milling machines, benchtop milling machines, and machining centers with standard DIN T-slot tables.
Check the vise's weight against the table's capacity. Bernardo vises {series or "PS/KV"} are sized for professional milling machines; smaller benchtop milling machines require lightweight models (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 vise: after thousands of clamps, they may show nicks or deformation. Replacement is self-sufficient 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 checking of parallelism with a dial indicator.
Chips accumulated 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.
