Carl Zeiss Contour and surface SURFCOM CREST

Combined CNC reference machine for contour and surface measurements SURFCOM CREST The flagship for contour and surface measuring technology from ZEISS features high resolution and a laser-interferometric measuring system. SURFCOM CREST is often used in calibration labs.

Precise, universal, dynamic – SURFCOM CREST is setting new standards in accuracy and speed. The machine measures surface parameters and contours in one measuring run and impresses with its extremely good ratio between the measuring range and the resolution of 42,000,000:1.

This enables the SURFCOM CREST to measure the slightest surface roughness and contours across a very large range – all within a single measuring run. The SURFCOM CREST works in the Z axis using a laser interferometer as a measuring system, making it extremely precise. The measuring station features a linear drive, ensuring that it is significantly faster and with lower vibrations than measuring machines with traditional spindle drives. The swiveling linear X tracing driver also enables greater flexibility with slanted workpieces.

Measure roughness and contour in a single run Low measuring error in in the X direction: ± (0.2+L/1.000) µm; ± 0.4 µm at L=200 mm Tracing driver straightness error: 0.05 + (3L/10,000) µm; 0.11 µm/200 mm Measuring system (X axis): diffraction scale Measuring system (Z axis): laser interferometer for excellent precision Extremely good stylus system resolution: 0.31 nm/50 mm More universal and exact thanks to the outstanding ratio of the measuring range to resolution: 42,000,000:1 High travel speed of up to 200 mm/s 200 mm tracing driver with a patented, non-contact linear drive Swiveling X tracing driver of approx. ± 45° offers greater flexibility Long penetration depth for measuring deep workpiece components via a cylindrical stylus system Optional topography measurement Base: solid and attractively-priced FX version with integrated, active vibration damping that is suitable for production or a space-saving DX version

The SURFCOM CREST flexes its muscles where precision and throughput are vital: in the automotive technology, mechanical engineering and medical technology industries. For example: the SURFCOM CREST is ideal for lenses, precise bearings, drive spindles, rails, injectors, implants and precisely milled, ground, honed and lapped parts. This is why the SURFCOM CREST is often found in calibration labs.

ACCTee PRO

One software, one report
ACCTee PRO software features a number of software tools for checking surface parameters, contours and form features. All data for a workpiece are entered into the same document: measurement data, measuring conditions, analysis conditions, the CNC measuring program and the report layout. This makes it possible to export all relevant measurement data and graphics, e.g. roughness and contour data, in one report.

Easy Mode

In Easy Mode, the software guides the user step-by-step through all the main steps of a measurement: from selecting measuring conditions and stylus calibration all the way through the measurement.

Expert Mode – offline programming

The Expert Mode allows users to generate CNC programs away from the machine. This increases machine capacity considerably.

Automatic feature evaluation (Al function)

ACCTee PRO automatically recognizes basic features – point, line and circle. Depending on the selected feature, the program also shows a pre-selection of appropriate analysis functions.

Help functions

ACCTee PRO also contains an integrated help function that offers both contextbased explanations as well as an index and key word search. Furthermore, the software features mouse-over help with short explanations.

Self-diagnosis

In the event of an error, the software immediately provides the user with possible causes using images and short texts.

Playback function – CNC repeat measurement at the push of a button

ACCTee Pro offers time benefits of up to 40 % during the analysis because a repeat measurement can be initiated at the push of a button via the repeat function.

Simple re-evaluation

Re-evaluate without re-measuring: changes to the analysis settings and their impact are immediately visible (patented).

Easy plan/actual comparison

Measurement data and nominal profile (IGES and DXF) can be quickly compared using ACCTee PRO. The actual data are optimally aligned using the best fit set-up. An aspherical analysis function is available.

Patented edge function

Even when large part deviations in a serial measuring operation occur, the part is measured in the CNC operation. The real contour/edge is found and the real values are exported. False measurements, which occur with conventional methods, are not possible.

Tolerance analysis

ACCTee Pro can perform a tolerance analysis for individually selectable parameters. The results are shown as an OK/Not OK symbol in the report.

Export formats for statistical evaluation

Serial measurements can be exported and evaluated via the qs-STAT option or via Excel and CSV. ZEISS PiWeb offers comprehensive evaluation possibilities.

Standard functions

Thread analysis function: fast slope calculation at the push of a button Fourier analysis Result exported in Excel format Configurable calibration alarms for greater reliability Higher accuracy through patented calibration of the stylus tip geometry

Extension options

Dominant waviness Lead twist measurement Measuring recirculating ball screw Topography evaluation Patented automatic roundness evaluation on gear wheels Piston analysis Asphere measurement Thickness measurement

Graphic evaluation and documentation

Get a customized report quickly With just a few clicks, you can generate a report in ACCTee PRO that meets your needs. Graphic and numerical displays can be combined meaningfully. Change the filter and analysis settings without re-measuring: the new report is immediately generated automatically. Furthermore, photos of parts and company logos can be easily added to the report
