Bespoke high precision multi axis positioning stages from Micromech:

Micromech has been working in partnership with Netherlands based company PM bearings for over six years. Together we have been providing micro and nanometric positioning systems to UK companies covering a wide range of industries.

Working with PM Bearings we strive to provide the optimum solution for precision positioning applications.

Core competence lies in the development, manufacture and integration of linear bearings, guidance systems, and mechatronic nano-positioning (vacuum) modules.

We have developed and produce bespoke systems for customers in the semiconductor, aerospace, medical and research industries as well as for the analytical and optical markets. In addition to our standard range of precision bearings and stages, over 50% of our products are custom designed and manufactured in-house.

Micro and nanopositioning using piezo:

PM BearingsThe demand for complex, high-precision linear systems is continually increasing worldwide. Specialists such as PM-Bearings therefore continue to develop in this area and create customised solutions in the field of piezo technology.

The design of each high-precision linear system or positioning table begins with the selection of the mechanical and electrical components that make up the final system.

There are many factors to be taken into consideration that influnce a system design and lead to the highest possible accuracy and repeatability. Factors include bearing type, materials and surface treatment, stiffness and stability of the system, encoder type, style of assembly, etc.

PM BearingsFurthermore, in order to design and build the optimum system it is essential to understand the environment in which the system is to ultimately work. Quite often measurements made during clean room assembly and test are found to deviate when the system is placed in its final operating location. When it comes to high accurate positioning stages, factors that apply outside a clean room environment are often overlooked.

PM BearingsYears of experience in the field of high precision positioning have taught PM-Bearings engineers the importance of environmental factors that must be considered during the design phase. Temperature of the working environment and the preload on the rails must be taken into account. Temperature differences (even body temperature) can cause deviations in high-precision systems affecting its characteristics.

The piezoelectric motors (an electro-mechanical drive system that converts the limited movement of a piezoelectric element into an unlimited translational motion) employed in a PM piezo positioning stage enable a backlash free linear motion with nanometer accuracy. The PM-Bearings Piezo positioning stages (available as plug-and-play) are equipped with an optical encoder with resolutions down to 10 nanometers.
