Masterpiece in the world #1
Laser tool measuring system capable of on-machine tool measurement and automatic detection of micro wear and breakage of rotary tools

Risk of declining machining accuracy caused by wear and breakage of tool tips

The continued use of worn or damaged tool tips can lead to various problems such as poor workpiece accuracy, tool breakage and declining productivity, even if the damage is slight. Measurement of tool tips requires detachment of tools from a machine, cleaning up of chips, and re-attachment of tools. They take some extra time and work, which can cause operation errors and machining accuracy errors. The automatic detection of micro wear and breakage of tools during machining has been a big issue to improve productivity. Wear of an R-shaped tip of a ball endmill, which are mostly used on 5-axis machines, is difficult to measure with a contact-type measuring system, so the demand has been high for a highly accurate non-contact type measuring system.

High-accuracy on-machine measurement of tools with a minimum diameter of 10 μm achieved by focused laser beam

The LaserControl Micro Compact NT, a laser tool measuring system by Blum, boasts the world’s highest accuracy. The company developed the product for the first time in the industry more than 25 years ago. The product is capable of measuring tool tips on a machine with laser beam and detecting micro wear and breakage without tools detached from machines in operation. Automatic measurement of tool tips can contribute to improvement in productivity. The LaserControl Micro Compact NT achieves measurement of tools with a minimum diameter of 10 μm by focused laser beam (BL105). Tools can be measured from the rotation speed, which also can solve machining accuracy issues caused by tool vibration.

The patented NT technology ensures stable measurement under a harsh environment inside the machine where coolant is used and chips are generated

The product achieves the highest degree of dust and water resistance protection level against mist, coolant and chips (IP68). The air-driven shutter mechanism and the air purge equipped at the laser receiving and transmitting section prevent coolant, powder dust and chips from entering a machine to ensure stable measurement under a harsh environment inside the machine.

The LaserControl Micro Compact NT enables measurement in microns by thermal displacement compensation to control heat inside a machine, the NT technology to achieve high-accuracy measurement under a severe environment, the original air blow system and special programs to support each functions.
