Port Wheel Lathe Machine

CSK8015/8011-[CNC] CNC wheel lathe is suitable for the CNC machining and repairing of the wheel sets of various types of vehicles (EMUs, subway trains, urban rail vehicles) with a gauge of 1435 mm after the wheel sets are dropped. Including machining and repairing of wheel tread, wheel flange, inner rim surface, an axle-mounted brake disc (inner/outer side), wheel-mounted brake disc (inner/outer side), and it has functions of automatic detection and measurement of wheel size, Measurement data transmission, and printing.

Functional Description

● The wheel lathe has the function of automatic wheelset size measurement before and after the wheelset machining, which can automatically measure the wheelset diameter, wheel flange thickness, wheel flange height, tread profile shape, wheel flange width, radial runout of the tread rolling circle, wheelset inner distance, the axial runout of the inner end face of the rim, QR values, etc.; The measurement data is automatically saved, exported, and uploaded by the CNC system.
● The wheelset drive mode of CSK8015/8011-CNC wheel lathe adopts of friction transmission
● It has safety protection and working environment protection function.
● It has a self-diagnosis of machine failure and related information display function.
● The wheel lathe adopts a through-type structure and a double tool holder machining method.
● The lathe is also equipped with a wheel stop device for the wheelset to enter the machine tool and a wheeling (pushing wheel) mechanism for the wheelset to roll out of the machine tool.
