BLUM standard measuring cycles

The measuring cycles for BLUM laser measuring systems can be used to measure and monitor over 90 % of all conventional cutting tools. The measuring cycles are available for many conventional controls. Your local BLUM-representative will gladly inform you about the range of features for your control.

Tool Breakage Detection

Non-contact breakage detection of centric tools such as drills, mills, engraving tools, taps and reamers.

Tool Setting

Non-contact tool setting in length and radius at nominal speed including compensation of dynamic spindle drift at high rotational speeds.

Single Cutting Edge Monitoring
