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:
1. Used for layout, machining and inspection jobs.
2. Made of high-quality steel and HRC55-62 hardness.
3. 90° V-Angles.

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.
