What is a CMM?

The term CMM stands for Coordinate Measuring Machine.
It's a precision measuring instrument used in manufacturing and quality control to measure the physical geometry of an object.

How they work

A probe (contact or non-contact) touches or scans the surface of a part.
The machine records X, Y, Z coordinates in 3D space.
Software compares the measured data to a CAD model or blueprint to check for dimensional accuracy, tolerances, and defects.

Common types of CMM

Bridge CMM – Most common, with a moving bridge over a fixed table.
Horizontal Arm CMM – Ideal for large parts (e.g., car bodies).
Gantry CMM – For very large/heavy components.
Inline CMM - Specifically designs production environments to reduce manufacturing time.

Cost of ownership

The initial expense of a CMM is only part of its lifecycle cost. Superior build quality delivers higher reliability and greater performance enabling more throughput, thereby reducing the total cost of ownership. Key features to consider are:

High build quality and performance.
A solid upgrade path in probe technology.
Advanced software technology.
Ongoing support and training..

Why would I need a CMM

Coordinate measuring machines (CMMs) turns quality control into a competitive edge. Unlike inconsistent handheld methods, it delivers micron-level accuracy on every part, catching defects before they reach customers. As designs grow complex, CMMs measure intricate features like threads, bores and sculpted surfaces that manual tools can’t reliably verify, eliminating rework and scrap.

Our systems integrate into your workflow, enabling real-time inspection without slowing production. Automation cuts labor, reduces errors, and supports 100% checks in high-volume lines, boosting first-pass yields and customer trust. With intuitive software, expert training, and responsive support, CMMs help you meet rising standards effortlessly. In precision manufacturing, quality defines success — investment in a CMM can secure your reputation and profitability.
