機場捷運車輪車床功能簡介 Introduction to the TIAA MRT Wheel Lathe Equipment
車輪車床整體配置。

車輪車床設備配置於青埔機廠主維修工廠之輪軸工場,主要功能為電聯車及工程車之車輪組踏面、煞車碟之加工,係以車輪組滾入、滾出方式操作的地面車輪車床。設備由機床、導軌、兩個尾座、舉升―驅動系統、量測頭的刀具鞍座、頂心液壓缸、輪組對心元件、鐵屑引導系統、傾斜式軌道平台、潤滑系統、控制面板、液壓動力單元、電力與控制系統、鐵屑輸送帶、灰塵過濾系統所組成。
車輪車床配備先進的CNC控制及量測系統,CNC控制系統具有無段變速進給系統,可調整縱向、橫向進給率、自動顯示刀具位置、故障診斷、車輪輪廓更換及重新書寫程式等功能,充分顯現CNC控制系統之精密加工能力。量測系統則可量測車輪輪緣高度、輪緣厚度及車輪半徑,亦可記錄加工時間、車號、轉向架號碼、操作者代號及加工前、後車輪對的踏面幾何尺寸,並可完整輸出報表。另因採乾式切削方式(無切削液),以設計簡單、可靠的刀具夾持,且同一刀具可加工車削不同車輪輪廓,使其切削程序達到高生產力及低車削成本。此外,並具有故障排除容易、維修成本低、人性化安全操作界面等,以及可長時間操作使用等優點,可有效達成維修作業要求。

The wheel lathe equipment is distributed in the wheel-axle workshop in Chingpu Depot. The main function of this equipment is to process the wheelset tread and brake discs of EMUs and construction carts by rolling the wheelset to operate the surface wheel lathe. Components of the wheel lathe includes machine tool, guideways, tailstocks, elevating-driving systems device, saddles with positioning-measuring heads, crossing cylinders, centring units of wheelset, chips chute system, inclined rail platform, hydraulic power pack, electrification control system, swarf conveyor and dust & fume exhaust.
The wheel lathe is equipped with the latest CNC and measurement systems. The precise processing capabilities of the CNC system which comprises a continuous variable inlet compartment includes adjusting longitudinal and transverse inlet rate, auto-display of cutting position, error diagnosis and wheel profile replacement and reprogramming functions. On the other hand, the measurement system can not only measure wheel rim height, thickness and wheel radius but export reports containing processed time, train numbers, bogie numbers, operator codes and before & after geometric dimensions of wheel treads. Furthermore, by adopting the dry machining method that utilizes simplified and reliable cutters with no cutting fluid produced in the process, advantages of high productivity with low cost can be achieved. Besides, this method has further advantages including allowing various wheel profiles to be reconditioned by the same set of cutters, easy troubleshooting, low maintenance costs and user-friendly interface which will fulfill comprehensive maintenance demands.
