YCM's DCV2018A-5AX Machining Center Features Stable Construction for Aerospace Work
YCM’s DCV2018A-5AX machining center, part of the Aero series, is designed to provide high speed and efficiency for aerospace applications.
YCM’s DCV2018A-5AX machining center, part of the Aero series, is designed for aerospace applications. The double-column, multi-axis VMC features an HSK-A63 spindle with speeds ranging to 18,000 rpm and offering 94 hp (70 kW). The linear axes provide rapid traverse rates of 1,181-ipm (30 m/min.). A Z-axis direct-drive motor with no counter balance provides responsive, precise, and backlash-free movement that improves surface finish, the company says. The direct-coupled drive on the X axis provides faster acceleration. The 78.8" × 59" (2,000 × 1,500-mm) table has an 8,800-lb (4,000-kg) load capacity. Options include a 120-tool automatic toolchanger as well a 250-mm Z-axis riser.
A reinforced double-column structure reduces vibration for better surface finish and extended tool life. The internal double-A-type ribbed-bed design offers full support for the table, distributing the force evenly. Roller linear guideways on all three axes and multiple oversized slider blocks improve cutting characteristics, the company says. The Y axis is designed with a large span in horizontal and vertical directions in order to withstand the headstock weight and machining forces.
The five-axis universal head is equipped with a direct-drive motor with resolution of 0.001 degree. The machine also features cross roller bearings capable of accommodating bearing loads in every direction. A Heidenhain encoder is standard for positioning the B- and C-axis headstock. Additional features include a pneumatic positioning clamping system, over-travel protection and a B-axis anti-drop function in case of power outage.
A manufacturer that is distinctive for its attention to in-cycle machining productivity describes its efforts to obtain efficiency improvements outside of the machining cycle. The shop’s primary tool is a simple, daily, graphical recap that illustrates when each machine tool was and was not making parts.
Finally there is an alternative to ballnose endmills for finishing 3D parts. The combination of finishing tools shaped to provide more cutting surface and a CAM system with the ability to apply them on a five-axis machining center can dramatically reduce finishing cycle times while delivering better surface finishes.
With so many choices in five-axis machining technology, how do you know which is best for your shop? First, consider the parts. Then, look at existing processes and potential five-axis benefits.
