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 regarding cutting edge breakage and missing tool inserts.

Tool Form Measurement

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

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-dependant thermal behaviour of machining centres.

RunoutControl*

Rapid run-out monitoring in less than 1 second for highly productive machining centres.

* The technology cycle is available for selected controls.

MicroWearControl*

Fast monitoring of tool cutting edges for microbursts in a highly productive environment.

* The technology cycle is available for selected controls.

3D RadiusControl*

Recording of form error on tools with circular cutting edge geometry. Data basis for 3D tool radius compensation “3D-ToolComp” by Heidenhain.

* The technology cycle is available for selected controls.

ChamferControl*

Length, radius and angle measurement on tools with angular edges such as spot facers, engraving mills, etc.
