AXM-210 Axle Measurement Station

The Simmons Axle Measurement System (AXM-210) automatically measures the wheel seat diameter of a railway axle to provide data to the wheel boring machine(s) when cutting wheel bores for making a wheel set. The machine eliminates the chance of human errors and closes the feedback loop in the Simmons automated mount cell process. It measures the diameter of both wheel seats simultaneously, producing a maximum cycle time of 2 minutes (excluding axle loading and unloading).

The AXM-210 can also function as a standalone machine and the measurement results can be stored to a database hosted locally on the machine or hosted remotely on the customer’s server.
