The MicroMet precision sine bar with a 200 mm roller center distance is a metrological tool designed for extremely accurate angle setting and verification in precision machining operations. This type of equipment is widely used in mechanical workshops, grinding departments and quality control laboratories where precise and repeatable angular adjustment is required.

The sine bar is manufactured from hardened, normalized and precision ground steel, ensuring excellent dimensional stability and perfectly parallel surfaces. These characteristics are essential to guarantee reliable results during angle setting and measurement operations.

Its operating principle is based on the use of gauge blocks placed under one of the sine bar rollers. By adjusting the height of the gauge blocks, the desired angle can be obtained with very high precision according to the trigonometric relationship between the height and the roller center distance. This method is widely used in grinding operations and metrological inspections due to its high accuracy and repeatability.

The 200 mm roller center distance, ground with a precision of 0.005 mm, ensures high accuracy when determining angles. The surface parallelism of ±0.004 mm guarantees excellent stability during machining or inspection operations.

Thanks to its precision design, the MicroMet sine bar is particularly suitable for precision grinding, dimensional inspection, toolmaking, high-accuracy machining and industrial metrology applications.

This tool provides a reliable solution for technicians, engineers and operators who require precise and repeatable angular adjustments during machining and geometric inspection tasks.
