High Accuracy 0.005mm High Stability V Blocks Jigs Fixtures for Mechanical Design Machining Workpiece Alignment & Inspection
Description:
V-Blocks are professional work holding fixtures that enable operators to securely locate and clamp workpieces for machining and inspection operations. The base, side faces and V contact surfaces are fully precision ground, offering stable, reliable and repeatable reference planes to guarantee consistent machining and measuring results.
To maintain long-term accuracy, V-Blocks require periodic inspection. Our V blocks are fully heat treated and precision machined, ensuring stable performance as dependable workshop holding tools.
The signature V-shaped dual contact surfaces firmly support components including round bar, tubular goods and shaft parts. Workpieces rest evenly against both faces of the V profile, which evenly distributes clamping pressure. This uniform force distribution locks the workpiece in a fixed position for precise milling, grinding, layout marking and runout testing.
Each matched-pair V Block is constructed from premium-grade steel, hardened to HRC 55–62 for superior wear resistance. Featuring a standard 90° V-angle and supplied with matching clamping brackets, our metric and inch specification V-blocks achieve high accuracy up to 0.005 mm (0.0002 inch).
Quick Detail:
1. Used for layout, machining and inspection jobs.
2. Made of high-quality steel and HRC55-62 hardness.

Product Highlights:
1.Precision Ground Reference Surfaces
Base, side faces and V contact surfaces are fully precision machined, providing stable, repeatable reference
planes for layout, machining and inspection tasks.
2.Optimized V-Shaped Clamping Design
Standard 90° dual V contact faces evenly distribute clamping force, firmly securing round bars, shafts and tubular
workpieces in fixed position during testing and processing.
3.High Hardness & Long Service Life
Constructed from premium steel and heat-treated to HRC 55–62, delivering outstanding wear resistance for
long-term heavy workshop usage.
4.Supplied as Matched Pairs with Clamps
Complete set includes paired V-blocks and matching clamping brackets. Metric and inch dimension specifications
cover a wide range of workpiece sizes.
5.Wide Application for Precision Metrology
Perfect work holding fixture for shaft runout testing, petroleum tubing inspection, layout marking, grinding, milling and
quality control in machinery & metrology labs.
Applications:
Securely clamp cylindrical workpieces for milling, grinding and light cutting processes. The evenly distributed clamping
force prevents workpiece shifting during processing, helping operators obtain consistent machining dimension accuracy.
FAQ:
Q1: Why precision ground surfaces matter for V‑blocks?
A: The base, side faces and V contact surfaces are fully precision ground. They create stable and repeatable reference planes, which guarantee consistent machining and measuring results for layout, machining and inspection work.
Q2: Do they come as matched pairs and include clamps?
A: Yes. They are supplied as matched‑pair V‑blocks together with matching clamping brackets. Metric and inch specifications are available to fit different workpiece sizes.
Q3: What accuracy level can these V‑blocks reach?
A: Our precision steel V‑blocks achieve high accuracy up to 0.005 mm (0.0002 inch), meeting strict precision requirements for metrology and high‑precision machining.
