Measuring machines – find manufacturers and suppliers

Measuring machines, also known as coordinate measuring machines (CMMs), are precise instruments for the three-dimensional measurement of geometric properties of physical objects.

They are used in many industries to check the accuracy of components and ensure that they meet specifications.

Below you will find the types and functions of measuring machines, their areas of application and their advantages.

Types and functions of measuring machines:

1. Tactile coordinate measuring machines (CMM):
   Mode of operation: These measuring machines use a tactile probe that touches the object to capture accurate 3D coordinates.
   Application: Ideal for precise measurements of solid components, often in the automotive and engineering industries.
2. Optical measuring machines:
   Mode of operation: Use cameras or lasers to capture the dimensions of an object without contact.
   Application: Suitable for sensitive or flexible materials that could be deformed by tactile measurement. Widely used in the electronics and plastics industries.
3. Laser scanner:
   Mode of operation: Scanning the surface of an object with a laser beam to create a 3D model.
   Application: Commonly used in quality control and reverse engineering where detailed surface measurement is required.
4. Multi-sensor measuring machines:
   Mode of operation: Combine tactile and optical measurement methods to enable complex measurements in one pass.
   Application: Versatile in aerospace, automotive and other high-tech sectors where different measurement approaches are required.
5. Gantry measuring machines:
   Mode of operation: A special type of CMM designed especially for measuring large workpieces.
   Application: Used in industries where large, bulky parts such as aircraft components or tools need to be inspected.
6. Manual measuring machines:
   Mode of operation: Measurements are taken by manually guiding the probe head.
   Application: Often used in smaller workshops or for less complex measuring tasks where flexibility and lower costs are paramount.

Areas of application of measuring machines:

1. Automotive industry:
Component testing: Ensuring that engine components, body parts and other vehicle parts are within tolerances.
Quality control: Checking the conformity of prototypes with CAD models.

2. Aerospace industry:
Measurement of complex geometries: Precise measurement of aircraft parts, such as turbine blades, landing gear and fuselage sections.
Material testing: Examination of deformations or deviations after load tests.

3. Mechanical engineering:
Tool and mold making: Measurement and testing of molds and tools to ensure precision in production.
Component testing: Ensuring the dimensional accuracy of mechanical components such as gears, shafts and bearings.

4. Medical technology:
Medical device testing: Measuring implants, surgical instruments and prostheses to ensure they meet stringent quality requirements.

5. Electronics industry:
Measurement of micro components: High-precision measurement of small electronic components and printed circuit boards.
Assembly monitoring: Checking the alignment and positioning of components in complex electronic assemblies.

6. Packaging and plastics industry:
Mold measurement: Inspection of injection molds to ensure consistency in mass production.
Packaging inspection: Measurement of packaging and plastic parts for quality assurance.

Advantages of measuring machines:

• High precision: enable measurements with micrometer accuracy.
• Versatility: Can be used for a wide range of materials and shapes.
• Automation: Many measuring machines can be integrated into automated manufacturing processes to ensure continuous quality assurance.
• Data analysis: The data collected can be used to analyze and improve manufacturing processes.

Measuring machines are essential tools in the modern manufacturing and quality control environment. Their ability to perform precise and repeatable measurements makes them particularly valuable in industries where the highest levels of precision and reliability are required

Here are the key aspects to look out for when buying measuring machines.

When purchasing measuring machines (coordinate measuring machines, CMMs), there are several important factors that should be considered to ensure that the machine you choose meets the specific requirements of your application.

• Measurement accuracy and repeatability: Choose a measuring machine that meets the required accuracy requirements of your application.
• Measuring range and component size: The measuring range of the machine must be large enough to fully accommodate the largest components to be measured.
• Measuring method and technology: Decide whether a tactile probe, an optical system or a combination of both technologies (multi-sensor) is best suited to your application.
• 3D scanning: If you need to measure complex surfaces or free-form surfaces, a 3D laser scanner or similar system may be a better choice.
• Software and user-friendliness: The measurement software should be powerful and user-friendly at the same time. It should offer features such as CAD import, automatic feature recognition and reporting.
• Integration into existing systems: Make sure that the measuring machine can be integrated into your existing manufacturing and quality control systems. Make sure that the machine has the appropriate interfaces and communication protocols.
• Robustness and environmental requirements: Consider the environmental conditions in which the machine will be used, such as temperature, humidity and dust. Some machines require air-conditioned rooms to meet their specifications. Pay attention to the quality of the construction and the materials used.
• Maintenance and calibration: Choose a machine that is easy to maintain and where wearing parts can be easily replaced. check how often the machine needs to be calibrated and whether this needs to be done on site or by the manufacturer.
• Certifications and standards: Make sure the machine complies with relevant industry standards and norms, such as ISO standards for measuring machines.

Choosing the right measuring machine depends on the specific requirements of the application, including the size, complexity and material properties of the parts to be measured.
