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

Monitoring of tools for broken or missing cutting edges.

Tool Form Measurement

Setting and monitoring of tools with circular cutting edge geometry in length, radius and cutting edge radius.

Tool Form Monitoring

Monitoring for cracks or wear by scanning the tool cutting edges.

Wear compensation

Compensation of tool wear using measurements between the machining steps. The wear value is stored as an additive correction value in the tool offset memory.

Temperature compensation

Compensation of the temperature-dependent thermal behaviour of machining centres.

Spindle Control

Recording and documentation of spindle wear for preventive maintenance
