Diagnosis of chatter marks
Diagnosis of chatter marks in turning, milling, drilling and grinding
The assessment of chatter problems begins with the manufactured component. A correct diagnosis of the causes is a prerequisite for targeted improvement measures. Vibration waves have to be analyzed seperately from interference waves which can occur when making several simultaneous cuts or can arise because of special rotary to oscillating frequency ratios or because of coupled oscillatory movements. Our experience over 15 years with over 1000 cases using advanced vibration and surface-measuring techniques qualify us as specialists in the detection and classification of chatter problems.
Surface examples
The following practical examples show how vibrations can affect workpiece quality in different processes (milling / drilling / turning / grinding). We would be pleased to support you in analyzing the causes of your specific vibration problem.
