| Task | We need high-precision milling. But high-accuracy milling requires measuring the actual tool diameter.And diameter corrections take time. |
| Point | The corner radius of Evolution type uses the tool centerline as its datum independent of the tool diameter. This allows high-accuracy milling compared to conventional tools, even when using nominal diameters. *The |

Portable Surface Roughness Tester
The auto-set unit* enables measurements to be made with a single button push, saving you time and increasing work efficiency.
|
The auto-set function safely controls descent of the detector, eliminating the possibility of operator error causing damage to the stylus. |
Auto-set unit* 178-010 This unit automatically completes a full measurement cycle of stylus contact, measurement, stylus retraction and detector auto-return from just one button push (stylus retraction and detector auto-return can be switched on and off by operating the drive unit).

Verification of geometrical tolerances, including roundness, is a must in today's quality-conscious environment.
Roundness measuring machines with the ability to perform product verification in conformity with ISO, JIS and other standards are indispensable to any quality control system that aspires to implementing high-grade quality assurance. Heightened awareness of production quality and higher quality goods will help enhance your corporate image with the buying public.
Roundness verification attempted using basic measuring tools involves the following drawbacks.
• Measurement is not conducted by a radiusmethod conforming to the standards, forwhich a reference axis is necessary.
• Measurement verification that meets theaccuracy required by the drawings cannot beperformed.
• Recorded profiles cannot be obtained.
Three-point method using an indicator and V-block has better resolution but is not sensitive to common lobing conditions.
• Reduction
