Transducer and Interface Modules

The detection of missing or broken tools helps to insure that the proper machining is being performed. Detection of tool wear and damage can help improve surface finish and tolerances.

The TECHNA-CHECK® (TC) systems detect the electrical power currently used by the spindle drive for the machining process or the vibrations sampled with an accelerometer and compare the work cycle with a given reference image.

• The effective power of a good tool can be programmed as reference profile. The limit values for the respective error state can be defined by parameters. A blunt or worn out tool requires more power for running a machining process the output curve reaches the wear limit (> Worn).
• If a tool breaks peak power is reached for a short time (> Break).
• If there is no tool the power consumption drops to the idle power value of the spindle and falls below the value assigned for “missing tool” (> Missing).

The configuration or parameters can be executed via the user interface on the unit of the system or from a PC. For this purpose a Windows-based software is available with which the adjustment and setting of the parameters can be easily modified at any time and which provides additional diagnostic and statistical functions.
