About ZEISS and Accretech
For more than 20 years ZEISS has worked with the Japanese metrology mogul Accretech, the leading provider of surface, contour and form measuring machines. This partnership delivers you the highest quality, innovative solutions and a global service network for surface form and geometry equipment.
Whether you need surface finish, roundness, or contour measurements, ZEISS/Accretech has the right solution for your application. Recent product innovations and enhancements put advanced technology in users hands that is easy to operate and more reliable than ever. Combining new electro mechanical achievements with our maturing ACCTee-Pro software make ZEISS/Accretech the best choice for precision metrology solutions.
NEX profilometers and surface finish measuring instruments from Accretech and ZEISS range from entry level hand held units to full CNC measuring solutions.
Evaluation of roundness, cylindricity and run-out demand high precision. These form testers are built with ultra-accurate rotary tables and liner R axis scales.
For surface, contour and form measurements, there is one software that covers everything: ACCTee PRO.
Contour Tracing and Analysis
NEX contour and profile measuring instruments from Accretech and ZEISS have several new features. Both Accretech’s general purpose and high accuracy detectors gives you best in class accuracy with temperature correction. Accuracy is guaranteed between 15 and 25 degrees C. You will also find expanded Z measuring range at +/- 30mm (60mm total) travel allowing both downward and upward measurement. To help with that Accretech has an improved carbon fiber stylus holder for up and down measurement. And a new safety system will protect the NEX drive in the event of a collision with workpiece or fixturing.
Linear Drives from Accretech
Accretech and ZEISS were the first to use linear drives. Now all of the NEX line machines come with an advanced “Precision Linear Motor Digital Tracing Driver” in either the standard 100mm travel or optional 200mm travel.
What is a linear drive? To start with, a conventional systems uses a mechanical ball screw drive with a motor, encoder and linear scale. Control response of repetitive back and forth motion is limited when determining very fine resolution movement. Accretech linear drives address that weakness by combining a linear motor and a scale for high response and precise positioning without backlash. Liner drives also reduce system harmonics or vibrations. Response, positioning and reduced vibraton are key characteristics in precision instruments like the ZEISS CONTOURECORD and SURFCOM NEX series.
Accretech linear drives also allow you to manually position a probe with ultra fine detail. Since they are not mechanical, you do not need to worry about maintenance issues like lubrication or grease. If those are not enough reasons, then consider the increased travel speed which will reduce your inspection times.
