Built-in Type ATC Run-Out D System

Aluminum high-speed cutting process monitoring device

  • Sudden machining defects.
  • Aren't they being caused by chips in the tool chuck?

Features

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.
