Magnetic V-Block INSIZE Pryzma PPSM 45 (model 6890-702)

Magnetic V-Block INSIZE Pryzma PPSM 45 is a precision work-holding accessory designed to secure round and cylindrical parts during inspection, marking, grinding and machining operations. The unit combines a V-shaped cradle with an integrated magnetic base that fixes workpieces firmly in the groove, enabling stable positioning and repeatable alignment for measuring and processing tasks in workshops and metrology labs.

Advantages

The magnetic V-block provides reliable magnetic clamping that reduces the need for mechanical fixtures and speeds up setup. Its V-groove geometry centers shafts, rods and pins for accurate inspection and machining. The compact design supports easy placement on surface plates, machine tables or inspection benches, and its stable hold minimizes part movement during measurement or cutting operations.

Suitable for

• Inspection and dimensional measurement of cylindrical parts
• Marking, scribing and layout work on shafts and rods
• Light grinding and machining of small round components
• Repeatable alignment tasks in workshop and metrology environments

Key specifications

• V-groove for secure seating of round and cylindrical workpieces
• Integrated magnetic base for stable clamping without additional fixtures
• Compact form factor for use on surface plates, benches and machine tables
• Suitable for small to medium-diameter shafts, rods and pins

How to use

Place the magnetic V-block on a clean, flat reference surface or machine table and ensure the magnet is engaged according to the device’s control (on/off or rotating contact). Position the cylindrical workpiece into the V-groove so it rests evenly on both faces. Verify alignment with measuring instruments such as dial indicators or height gauges before performing inspection, marking or machining. Disengage the magnetic hold when removing or repositioning the part to avoid disturbing the setup.

Usage recommendations

Keep contact surfaces and the V-groove clean and free of chips, coolant or oil to maintain reliable magnetic contact and consistent positioning. Use appropriate personal protective equipment and follow machine tool safety procedures when performing grinding or machining operations while the part is magnetically clamped.
