Accretech Roundness and Cylindrical Profile Measuring Instruments Rondcom 43C/43C-S/41C/31C Series

Product Code: Rondcom 43C/43C-S/41C/31C Categories: , Tags: , , , ,

Accretech Rondcom Series Compact Desktop Roundness Measuring Instruments with High-End Analysis Functions Offer Superior Cost Performance by MSP Metrology (M) Sdn Bhd from Accretech Japan.



Centering/Tilting/Leveling Support Functions (Patented)

Easily adjust eccentricity and tilt between the center of rotation and the center of the workpiece simply by adjusting the displacement to zero as indicated on the bar graph in the alignment display.

Semi-Automatic Measuring Function with Specification of Measuring Height

All Orientation Detector (Optional) May Be Provided

The detector expands the measuring range to ±1000µm and enbles measuring force and front travel (stylus drop) adjustment.

R-axis Scale for Small, High-Accuracy
Workpieces (R43C-S)

R41C Supports High Column: Z = 500 mm (Option)
