China CMM Fixture Suppliers - 108-Piece Flexible Fixture Set for Accurate Measurement Support from Factory
What is the primary function of a CMM fixture?
The primary function of a CMM fixture is to securely hold and precisely position workpieces on the measuring machine's workbench, preventing movement or deformation during the probing process to ensure highly accurate inspection results.
How do CMM fixtures prevent part deformation?
CMM fixtures are designed to apply optimal, controlled clamping forces and provide multi-point support. This guarantees that even delicate, thin-walled, or complex parts remain structurally undistorted while being measured.
Can these fixtures be adjusted for different component shapes?
Yes, modular CMM fixtures are highly adjustable. They feature components like standard pins, stop blocks, and clamps that can be repositioned to accommodate various geometries, dimensions, and custom configurations.
Why is correct positioning essential in coordinate measurement?
Correct positioning ensures that the coordinate system of the workpiece aligns accurately with the measuring machine's axes. This minimizes setup errors and ensures that geometric tolerances are measured from the correct datums.
What materials are typically used for CMM fixtures?
CMM fixtures are commonly constructed from lightweight, durable, and dimensionally stable materials such as anodized aluminum, hard-coated steel, and non-marring plastics to prevent scratching the measured components.
