What is a contour measuring device?

A contour measuring device is a high-precision measuring instrument used in industrial production and quality assurance. It is used for the precise measurement and assessment of surface contours, i.e. the shapes and structures of components or products.

Contour measuring devices play an essential role in quality control and product development. They help to ensure accuracy and compliance with industry standards.

The advantages of a contour measuring device

A contour measuring device offers numerous advantages. First of all, it enables high-precision measurement of surface contours. This is particularly important in industrial sectors where the slightest deviations have a significant impact on product performance. 

Another advantage is the ability to perform fast and repeatable measurements. This consistency ensures consistent product quality and helps to reduce rejects and rework, resulting in significant cost savings.

Contour measuring machines are also generally somewhat easier to operate than other machines because intuitive controls and software enable efficient measurement and data evaluation. The process not only saves time, but also improves working conditions for staff.

Applications of contour measuring devices

Contour measuring devices are used in numerous industrial sectors. Their precise measuring functions are more important than ever in the automotive industry, aerospace, medical technology and many other sectors.

In the automotive industry, for example, contour measuring devices are used to check the contours of engine components, transmission parts and other components. Their precise measurements ensure that all parts fit together perfectly during assembly and guarantee optimum performance.

In the aerospace industry, contour measuring devices are used to check the surface contours of aircraft and spacecraft parts. The technical requirements here are particularly high, as even the smallest deviations can have serious consequences.

Contour measuring devices are also of great importance in medical technology. They are used to measure and check medical devices and implants to ensure the safety and effectiveness of these products.

Use in measuring laboratories

Measuring laboratories are another area in which contour measuring devices play an important role. Here, they are used to measure and check components and products under controlled conditions.

In a measuring laboratory, a contour measuring device can help to achieve accurate and repeatable measurement of complex contours. This is often necessary to ensure that products meet certain quality standards or legal requirements.

In addition, measuring laboratories are often confronted with a variety of different components and product types. Flexible contour measuring devices are able to measure a wide range of surface structures and specific shapes, making them an indispensable tool in these areas.

High-precision contour measuring devices

High-precision contour measuring devices are specialized instruments designed for particularly demanding measuring tasks . They can measure surface contours with high accuracy of a few micrometers or even nanometers.

These high-precision devices use the latest technologies to ensure maximum measurement accuracy. They are often equipped with advanced sensors that offer a very fine resolution and use specialized software for data evaluation.

High-precision contour measuring devices are essential in areas where extremely accurate measurements are required, such as microelectronics, precision mechanics or medical technology. Here, even the smallest contour deviations can have a significant impact on the performance and reliability of the products.

Investing in a highly accurate contour measuring device can offer significant benefits, including improved product quality, reduced waste and improved quality assurance effectiveness.

Flexible contour measuring device

A flexible contour measuring device is an adaptive measuring instrument capable of measuring a variety of surface contours. The device is designed so that it can be adjusted to different product types and shapes, making it an extremely versatile tool in quality control and product development.

Flexibility is particularly relevant in industries where products are constantly being developed and improved. A flexible contour measuring device enables manufacturers to react quickly to changes in product design while ensuring compliance with quality standards.

Most flexible contour measuring devices have user-friendly software that makes it easy for users to make changes to the measurement parameters without much difficulty. This can be particularly useful when developing new products or when adjustments need to be made to existing products.

Electronic shape determination of contour measuring devices

Electronic form and roughness determination is an advanced function of many contour measuring devices. It makes it possible to measure both the exact shape and the surface roughness of an object with high precision.

The shape of an object can have a strong influence on its function. Deviations in the shape of engine parts, for example, can lead to a loss of performance or even damage. This is why precise measurement and monitoring of the shape is of absolute importance in many branches of industry.

The roughness of a surface, on the other hand, can influence aspects such as friction, wear, adhesion and even the aesthetic appearance. Contour measuring devices that can perform roughness measurement therefore offer additional benefits.

Modern contour measuring devices that perform electronic form and roughness measurements use advanced sensor technology and specialized software to achieve precise and repeatable measurements. The process enables comprehensive surface characterization, leading to better quality control and ultimately improved end products.

Measurement of surface structures, grooves and tooth shapes

Contour measuring devices are able to accurately determine the shape of various surface structures, including grooves and other special shapes. This capability is particularly important in industries where such structures play a role in the function of a product.

Grooves can play a crucial role in lubrication in engine or transmission parts, among others, and thus influence the service life and performance of the part. Accurate measurement of the groove shape is therefore crucial to ensure that they fulfill their purpose.

Other special shapes, such as threads or tooth shapes, are also important in various applications. A contour measuring device that is able to accurately measure such structures can help to ensure the quality and functionality of the end product.

Types of contour measuring devices 

There are various types of contour measuring devices, which differ according to their measuring functions and applications. Here are some of the most common:

  • Contact contour measuring devices: This type of device uses a physical probe that moves over the surface of the object to be measured. This method is also known as the stylus method or 2D stylus method. It is particularly useful for measuring simple contours and usually offers high accuracy.

  • Optical contour measuring devices: With these devices, the contour is determined using optical methods such as laser scanning or white light interferometry. They are particularly suitable for measuring complex or sensitive contours that could be damaged by physical contact.

  • 3D contour measuring devices: These devices are able to perform three-dimensional contour measurements. They are particularly suitable for measuring complex geometries and can often measure surface roughness and shape accuracy at the same time.

Choosing the right type of contour measuring device depends on the specific application and the user's requirements. In many cases, the combination of different measuring methods can be the best solution to perform a comprehensive and accurate contour measurement.
