Product Details
PCD V Blocks DETAILS:
PCD (Polycrystalline Diamond)
V-blocks are precision metrology tools designed for holding and inspecting
cylindrical workpieces, particularly in applications involving abrasive
materials or requiring high wear resistance. These blocks are commonly used in
industries such as aerospace, automotive, and electronics for tasks like
marking centers, checking concentricity, and supporting cylindrical components
during machining or inspection processes.

Key Features of PCD V-Blocks
- Material Composition:
PCD V-blocks are constructed from a composite of fine diamond crystals and
a metal binder, offering exceptional hardness and wear resistance.
- Applications:
Ideal for holding and inspecting cylindrical work pieces made of hard
materials, such as ceramic, carbide, or composites, during operations like
grinding, milling, and inspection.
- Design:
Typically, PCD V-blocks feature a 90° vee groove, precision-ground
surfaces, and may come with integrated clamps or magnetic bases for secure
holding.
????
Grades and Accuracy
PCD V-blocks are available in
various grades, which determine their precision:
- Grade 0:
Highest precision, with a parallelism tolerance of ±0.008 mm. Suitable for
applications requiring extremely high accuracy.
- Grade 1:
Good accuracy with a tolerance of ±0.016 mm, suitable for most industrial
applications.
- Grade 3:
Lower precision with a tolerance of ±0.064 mm, adequate for applications
where ultra-high precision is not critical.
????
Common Applications
- Marking Centers:
Aligning cylindrical work pieces to mark their centerlines accurately.
- Checking Concentricity: Verifying the alignment of cylindrical parts to
ensure they are concentric.
- Supporting Components:
Providing stable support for cylindrical parts during machining or
inspection processes.
- Inspection of Runout and Circularity: Assessing the roundness and straightness of
cylindrical parts.

Frequently Asked Questions (FAQ)
- What is a PCD V-block?
- A PCD V-block is a precision tool used to hold and
inspect cylindrical workpieces, made from a composite of fine diamond
crystals and a metal binder, offering exceptional hardness and wear
resistance.
- What materials are PCD V-blocks suitable for?
- PCD V-blocks are ideal for holding and inspecting
cylindrical workpieces made of hard materials such as ceramic, carbide,
or composites.
- What is the purpose of the vee groove in a V-block?
- The vee groove, typically at a 90° angle, is designed
to securely hold cylindrical parts, ensuring stability during marking,
machining, or inspection processes.
- How do I choose the right grade of PCD V-block?
- Select the grade based on the required precision for
your application. Grade 0 offers the highest precision, while Grade 3 is
suitable for less critical applications.
- Can PCD V-block be used for both marking and
inspection?
- Yes, PCD V-blocks are versatile tools used for both
marking centers and inspecting cylindrical work pieces for concentricity
and roundness.
- Are PCD V-blocks available with clamps or magnetic
bases?
- Yes, many PCD V-blocks come with integrated clamps or
magnetic bases to secure the workpiece during operations.
- What is the typical tolerance for PCD V-blocks?
- The tolerance varies by grade: Grade 0 has a tolerance
of ±0.008 mm, Grade 1 ±0.016 mm, and Grade 3 ±0.064 mm.
- How should PCD V-blocks be maintained?
- Regularly inspect for wear or damage, keep surfaces
clean and free from debris, and store in a dry, protected environment to
maintain accuracy.
- Can PCD V-blocks be used for non-cylindrical parts?
- PCD V-blocks are specifically designed for cylindrical
parts; for non-cylindrical parts, other fixtures or supports should be
used.
- Where can I purchase PCD V-blocks?
- PCD V-blocks can be sourced from specialized tool
manufacturers and suppliers, such as JD Diamond Tools.
