Portable CMMs have become the most popular shop floor measurement tool in the world and for good reason. Portable CMMs or PCMMs are highly portable, inexpensive, highly accurate and incredibly rugged, making it the number one measuring instrument for a modern manufacturing facility. The CMM software allows multiple part setups to be integrated together to produce one inspection program.
At CMMXYZ, we’re proud to be a leading metrology solutions provider specializing in portable CMM arms and portable CMM machines. As North America’s coordinate measuring experts, we help clients understand the importance of high-quality metrology equipment and how it translates to a more efficient and accurate production process.
Portable CMMs offer a unique ability to accurately and intricately measure even the most complex geometric objects. Their measurement capabilities are more flexible and convenient and can be adapted to any shop floor.
We offer a selection of new and used portable coordinate measuring equipment designed to stream your operations, improve production practices, and generate reliable on-site measurements.

Hexagon’s innovative Absolute Arm is the lightest, most flexible, and most accurate portable coordinate measuring machine on the market, featuring proprietary absolute encoders and reliable, high-performance laser scanners.
The AS1 Laser Scanner is the flagship 3D scanning sensor and is used with the Absolute Arm 7-Axis system. It features innovative blue-laser light and systematic high-intelligence noise elimination.
The Absolute Arm 7-Axis provides optimal freedom of movement with high-end 3D scanning and digitization capabilities and strong carbon-fibre construction. This portable CMM arm can withstand even the toughest environments.
The Absolute Arm 6-Axis is known as the most effective portable coordinate measuring machine for CMM probing applications and includes configurable grip shapes and sizes for maximized convenience.
A portable coordinate measuring machine is a device that’s used to collect data points from the surface of a geometric object. The difference between a portable CMM and a bridge CMM or gantry CMM is its ability to be transported to various areas of a shop floor and can collect data from different types of parts and at various angles.
An optical CMM is a non-contact measuring machine that uses images to perform its measurements. Using image processing technology, an optical CMM can perform automatic measurements that are equally fast and accurate.
A portable coordinate measuring machine measures the surface of a geometric object using a measuring arm — also referred to as an articulating arm.
With each point of contact, portable CMM arms collect 3D coordinates or measuring points, which are then compared to CAD models through computer-aided inspection. This ensures whether or not the measured part meets current quality standards.
These lightweight and convenient measuring machines can accurately gather data points from different angles of a specific part and can be used for additional purposes, including rapid prototyping and reverse engineering.
There are several reasons why manufacturers and shop floor operators use portable CMMs and CMM arms to streamline their production and operation processes, including:
At CMMXYZ, we work with manufacturers and shop floor operators across North America to achieve greater efficiency and accuracy within their production process. We offer a selection of quality new and used metrology equipment, including portable CMM machines, to suit every industry and every measuring need.
Six-axis arms are used for hard probing, whereas seven-axis arms are required when additional articulation is needed for specialized probing or a laser scanner.
Six-axis portable arm with a solid probe will deliver accuracies between 15 to 20 µm, whereas armed with a laser scanning probe precisions vary but are generally within the 50 µm range.
Getting the best precision from a portable arm does require experience but for the most part, it is a very subjective measuring device and is dependent on the stability of the machine and the experience of the operator.
The current standard is ISO 10360-12 with the scanning accuracy according to ISO 10360. This must be performed by an ISO 17025 certified Laboratory.
There are three primary manufacturers of portable CMM arms — Faro, Hexagon (formerly ROMER), and Kreon.
Each machine offers a unique set of features and benefits, and can be tailored to meet your metrology needs. Our specialists will take you through our selection of new and used equipment so you can better determine which CMM manufacturer is right for your business.
Portable arms may be moved around the job to be measured, this process is generally termed as leapfrogging. The operator may accomplish this by selecting data points on each surface to be measured that can be acquired in the new position.
Although both pieces of equipment are designed to digitize objects, there are distinct differences between portable machines and 3D scanners.
Portable CMM machines are designed to collect data swiftly, simply by using the machine’s probe to make contact with the object. This type of equipment is ideal for scanning objects with hard edges, including sheet metals, in addition to reflective, dark, or shiny parts.
3D Scanners, on the other hand, are non-contact tools that capture an image of an object, which collects more data points. It is often used to measure complex surfaces, although, unlike a portable coordinate measuring machine, using a 3D scanner is more time-consuming.
While both machines are used to measure and collect data points, there are important differences to note when deciding whether a portable or fixed CMM is right for you.
A portable CMM can be transported around the shop floor with ease and is typically used for large-scale inspections, rapid prototyping, and reverse engineering. This type of machine produces accurate measurements in controlled environments and is often a more cost-effective option than its counterparts.
A fixed CMM, on the other hand, is often best suited for projects that require collecting measurements of oversized parts in a more automated manner. Depending on the degree of automation, a fixed machine repeating inspections at a high volume with ideal cycle times is more efficient. In most cases, this type of equipment is more costly than a portable CMM or a portable CMM arm.
If you’re considering purchasing a portable coordinate measuring machine, there are several specifications and factors to be aware of before purchasing any metrology equipment.
Level of Accuracy
Understanding your accuracy requirements will ensure you purchase a machine that meets your current needs and avoid overspending on equipment.
The Measured Part
A portable CMM is designated by its working volume. Select a machine that is capable of measuring your desired parts and can handle any complex surfaces.
Your desired end results will ultimately determine which CMM is best suited to your needs. If you’re performing an inspection, your requirements will likely vary from machines that are tailored for reverse engineering. This will also help ensure you don’t spend money on additional software you don’t need.
