(Incl. Tax: €164.70)
The MicroMet precision sine bar with 100 mm roller spacing is designed for accurate angle setting and verification in precision machining and dimensional inspection operations. Manufactured from hardened, normalized and precision-ground steel, it provides excellent dimensional stability and perfectly parallel surfaces. Used together with gauge blocks, it enables extremely precise angular adjustments during grinding and metrology tasks. With 0.0035 mm roller spacing accuracy and ±0.003 mm parallelism, it is ideal for surface grinding machines, precision workshops and quality control applications.
The MicroMet precision sine bar with a 100 mm roller center distance is a metrological tool designed for the accurate setting and verification of angles in precision machining operations. This type of equipment is widely used in grinding departments, mechanical workshops and quality control laboratories where precise and repeatable angular positioning is required.
The sine bar is manufactured from hardened, normalized and precision-ground steel, ensuring excellent dimensional stability and perfectly parallel surfaces. This construction guarantees reliable results during both machining operations and metrological inspection activities.
Its operating principle is based on the use of gauge blocks positioned under one of the rollers of the sine bar. By adjusting the height of the gauge blocks, the desired angle can be achieved with very high accuracy according to the trigonometric relationship between the block height and the roller center distance. This method is widely recognized as one of the most precise techniques for angle setting in grinding and inspection processes.
The 100 mm roller center distance, ground with a precision of 0.0035 mm, allows extremely accurate angular positioning. The surface parallelism of ±0.003 mm ensures excellent stability during machining or measurement 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.
