The Simmons Wheel Turning Center (WTC-250) is a robust wheel borer for boring and machining railway wheels in high production wheel shops. The machine structure consists of mineral polymer composite castings for maximum rigidity and vibration absorbing properties.
The bridge straddles the wheel while cutting for optimal stiffness. Front-to-back motion is achieved by dual ball screws and dual absolute linear encoders. The ram is carried in box ways and fitted with a heavy-duty quick change tool interface. An automatic tool changer provides for redundancy and increased productivity. Single point tooling supplies considerable flexibility. The integrated measurement system allows for pre-machining workpiece measuring and user-selectable degrees of post-machining part verification.
The WTC-250 is also available as an "mc" version that additionally provides live tooling for drill and tap and/or oil hole drilling, bringing those functionalities into one versatile machine.
The Siemens CNC control is provided with a Simmons HMI utilizing railway wheel shop terminology, eliminating the need for operators to learn typical machine tool programming language. The system easily interfaces with other systems to receive wheel and axle information; it will additionally store production and dimensional results as desired.
