How Do Chips in the Tool Chuck Cause Defects?

In an ATC machining center, defects can be generated during ATC when chips get into the space between the tool taper and the main spindle. For years, machining centers have looked for a solution to this problem, which is particularly prevalent during high-speed cutting of aluminum.

Monitoring High-Speed Cutting of Aluminum

Because of shorter processing times, reductions in the amounts of coolants and other aluminum process demands, the frequency of chips getting into the tool taper during ATC is increasing. During high-speed cutting of aluminum in particular, a measurement instrument must be able to detect 100% of chip invasion into the tool taper so defects are not generated.

0.3 Second Measuring Time

An eddy-current sensor allows measurement in a mere 0.3 seconds (at 600 rpm). Since the measuring tool is selectable, measuring time is not affected by the cycle time. A dedicated run-out detection system algorithm (patent pending) calculates true run-out for detection capability that cannot be achieved by commercially available eddy sensors. All of this means that the system delivers precise, reliable detection in an automated line.

Low Cost, Integrated Type

By connecting a PC to this device, you can set up parameters and collect measurement data. This device need not be connected to a PC when performing regular measurement. All NC communication has been incorporated in to the OK/NG functions, which greatly reduces cost. Because of all of this, this system is being adopted by many machine tool manufacturers.
