Dec. 10, 2020New CMM Expands and Enhances HPM’s Quality System

Receiving high-quality parts is one of the critical factors that HPM customers look for when choosing a partner. To meet our customers’ needs and to further expand our inspection capabilities, we recently purchased an advanced quality inspection system – a Zeiss CONTURA coordinate measuring machine (CMM). This purchase demonstrates our on-going commitment to continual improvement in process and quality.


Our customers are increasingly designing parts with tighter tolerances, and many have incorporated their own advanced CMMs. This purchase will provide increased accuracy with tight tolerance parts and provide continuity between our measurements and our customers’.

The Zeiss CONTURA is equipped with a multi-application sensor system, which provides tactile and optical measurement on a single machine. The tactile sensors allow us to obtain a high level of accuracy and contact angle flexibility, either through point-by-point measurement or scanning measurements. Optical measurement is useful for quickly measuring complex shapes, such as to ensure processes are in spec, and for reverse engineering.

It has a workspace size of 900mm x 1800mm x 800mm (35 in x 70 in x 31 in), allowing us to measure larger parts with the same accuracy and efficiency. A singular set up with vertical and horizontal measurement, 3D measurement, and an articulating head with a+/-180 degrees tilt range, the CMM allows us to measure multidirectional axes without moving the part, ensuring a more accurate measurement.   It also offers programmable repeat evaluation, which ensures that each part in a multi-part study, for example, is measured exactly the same.

The CMM software offers some of the most widely used geometric dimensioning and tolerance (GD&T) tools: true position and concentricity. The GD&T true position tolerance, sometimes referred to as just tolerance, tells us how far a feature location can be from its ‘true position.’ Concentricity provides a tolerance for the coaxiality of two cylinders’ axes. This would be used, for example, if there are two holes on opposite sides of a component and the centers are expected to be on the same axis.

The software has reporting capabilities, giving us the ability to provide additional data to our customers.

The ZEISS CONTURA marries maximum flexibility and maximum precision, allowing us to meet our customer’s needs as technological advances lend themselves to tighter tolerances and more complex geometries. At HPM, our commitment to process and quality is strong.
