Toolroom Use V Blocks Precision Vee Blocks for Design Processing Clamping & Runout Checking Work


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:

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: What kinds of workpieces can be clamped on these V‑blocks?
A: Perfect for round bar stock, tubular goods and various shaft parts. Workpieces sit evenly against both V‑faces, clamping force is well distributed without workpiece shifting.


Q2: Do V‑blocks need regular maintenance?
A: To keep long‑term accuracy, periodic inspection is required. Keep contact surfaces clean, avoid heavy impact and scratches on ground reference faces. Proper maintenance will extend service life.


Q3: What is the difference between matched‑pair V‑blocks and single V‑block?
A: Matched‑pair V‑blocks are machined as a set to ensure parallelism and height consistency. When supporting long shafts or tubular parts, paired units maintain stable coaxiality; single V‑block cannot satisfy such measuring and clamping demands.
