Who is the BM 125 drilling machine vice for
The BM 125 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: rapid 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 drill press vise used for?
The BM 125 mm vise is sized for drill presses and drilling machines, with reduced weight and T-slots for quick table mounting.
Drill press vises are lighter than milling vises (less rigidity in the guides, but sufficient for the lower torque of drilling). The BM series is for drill presses, with a swivel base.
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 workpieces >100 mm, choose 125 mm or larger vises.
Which machine is it mounted on?
It is mounted on drill presses and bench drilling machines with a standard table.
Check for the presence of T-slots on the drill table. Milling machines require precision vises (ilgili, KV, PHV), not drilling machine vises.
Are the jaws replaceable?
Yes, the jaws are hardened, ground, and fully replaceable. This is a significant 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 independent using the dedicated fastening screws. Krollit provides original replacement jaws.
How is accuracy maintained?
Regular cleaning of guides and jaws, application of a light oil film on sliding parts every 50 hours of use, periodic parallelism check with a dial indicator.
Chips accumulated in the guides compromise parallelism accuracy. 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.
