A Magnetic V-Block helps maintain the position of round workpieces during measurement and workshop operations. Compared with a standard mechanical V-block, a magnetic V-block offers an additional magnetic holding function, making it useful for setups where stable positioning and convenient workpiece handling are important.
It combines V-shaped support with magnetic retention, providing a practical workholding option for suitable ferromagnetic workpieces.
Hanxin provides Magnetic V-Blocks for positioning and holding cylindrical workpieces during precision inspection, marking and grinding operations. Featuring a 90-degree V-groove and a magnetic operating mechanism, this measuring tool combines V-shaped workpiece support with magnetic retention for suitable ferromagnetic components.
Hanxin's Magnetic V-Block features a precision-machined V-shaped supporting surface and a side-mounted operating lever. Different dimensional specifications are available to accommodate various workpiece sizes and inspection requirements.
The main working feature of a Magnetic V-Block is its combination of a V-shaped supporting surface and magnetic workholding functionality.
90-Degree V-Groove Design
The 90-degree V-groove provides a defined seating area for cylindrical workpieces. When a round component is placed in the V-shaped groove, the two inclined contact surfaces help establish its position relative to the block's reference surfaces.
Magnetic Workholding Mechanism
Unlike a standard V-block that relies on mechanical support and an external clamping arrangement, a Magnetic V-Block incorporates a magnetic holding function for magnetically responsive workpieces. Magnetic retention can reduce the need for separate mechanical clamping in suitable setups and provide better access to the workpiece surface during certain measuring and marking operations.
Hanxin's Magnetic V-Block is designed with a 90-degree V-groove and precision reference surfaces. The available dimensional specifications cover different block sizes for cylindrical workpiece positioning.

Magnetic V-Blocks are used in precision measurement, workpiece positioning and metalworking operations involving cylindrical components. Their V-shaped support and magnetic holding function make them suitable for several workshop applications.
1. Precision Inspection and Measurement
A Magnetic V-Block provides support for cylindrical workpieces during dimensional inspection. Shafts, round bars and other suitable components can be positioned in the V-groove for checking alignment, runout and other geometric characteristics with appropriate measuring instruments.
2. Grinding Operations
During suitable grinding setups, a magnetic V-block can help hold cylindrical workpieces in position while providing access to the exposed surfaces.
3. Marking and Scribing
Magnetic V-Blocks can support round metal components during center marking, line marking and layout work. By retaining the workpiece in a defined V-shaped position, the magnetic V-block helps reduce unwanted movement during marking operations and makes it easier to access the exposed workpiece surfaces.
4. Cylindrical Workpiece Positioning
In mechanical workshops, shafts, cylindrical bars and similar components often require stable positioning during inspection and preparation processes.
Both Magnetic V-Blocks and standard V-blocks are used to support cylindrical workpieces. However, their workholding methods differ.
| Comparison | Magnetic V-Block | Standard V-Block |
|---|---|---|
| Main Structure | V-shaped supporting surface with magnetic mechanism | V-shaped supporting surface |
| Workpiece Holding | Magnetic retention for suitable materials | Mechanical support with an appropriate clamping arrangement |
| Positioning Method | V-shaped positioning combined with magnetic holding | V-shaped mechanical support |
| Workpiece Material | Magnetically responsive materials | Materials compatible with the supporting and clamping setup |
| Typical Applications | Inspection, marking and suitable grinding setups | Inspection, marking, positioning and machining setups |
| Clamping Arrangement | Magnetic mechanism | External mechanical clamping when required |
A Magnetic V-Block is useful when magnetic retention can simplify workpiece positioning. A standard cast iron V-block remains a practical choice when mechanical support and conventional clamping are preferred. For more options, explore Hanxin's Cast Iron V-Blocks product.
