Who is the BMI 125 industrial drilling machine vice for
The BMI 125 industrial drilling 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 serial processing: quick and repeatable clamping for production cycles.
Not suitable for: turning cylindrical parts (lathes require self-centering chucks, not milling vices).
Frequently Asked Questions
What is a drilling machine vice for?
The BMI 125 mm vice is sized for pillar drills and drilling machines, with reduced weight and T-slots for quick fastening to the table.
Drilling machine vices are lighter than milling vices (less rigidity in the guides, but sufficient for the lower torque of drilling). The BMI series is for industrial drilling machines.
What does the 125 mm dimension indicate?
It indicates the jaw width (125 mm). The clamping width is generally equal to or slightly greater than the jaw width.
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 125 mm or larger vices.
Which machine is it mounted on?
It is mounted on pillar drills and bench drills with a standard table.
Check for the presence of T-slots on the drill table. Milling machines require precision vices (PS, KV, PHV), not drilling vices.
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 can show indentations or deformations. Replacement is self-managed 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 vice at the end of the shift to prevent rust on ground parts. Acceptable parallelism tolerance: 0.02-0.05 mm over the length.
