PT1 In-line Diameter Gage
Precise size control of small parts and spools at production rates.

The PT1 In-line Gage is a unique solution to a difficult problem - how to automate size control on automotive transmission spools and similar small, multi-diameter parts. The PT1 provides the accuracy and throughput, as well as the flexibility for changeover, that manufacturers of these parts have been looking for.

The gage station is mounted adjacent to the infeed grinder, turning center, or screw machine. Parts are fed from the machine output chute directly into the gage magazine. When a switch confirms that the part is located, it is pushed through the measuring zone located between the reference rails and the probe contacts.

As the part passes through, the D500 Gage Controller samples the probe data at high speed for each measured diameter. Special software resolves the dynamic data into accurate size values. These values are used for accept/reject decisions and are analyzed for trends to see if a machine compensation output is needed.

The PT1 has demonstrated dynamic repeatability of .0003mm (.000012") at throughput rates of 12-15 parts per minute.

The gage station can be reconfigured for different parts by adding, subtracting, or re-positioning probe units and spacers. Sets of probes and spacers can be pre-assembled off-line to provide quick-change capability.

The D500 Gage Controller provides a range of software methods for trend-based size control. The advanced IPC option (Intelligent Process Control) significantly outperforms all other compensation techniques, and can control a machine to its best possible operating capability.
