Bridgeport V1320's Dual Y-Axis Bearings Increase Surface Quality
Hardinge has added the V1320 to Bridgeport’s V series of vertical machining centers. The machine is designed for high capacity and performance in the aerospace, automotive and energy markets. Among the machine’s features are dual Y-axis ballscrews said to promote surface quality and roundness accuracy, acceleration, reduced vibration, and increased tool life.
With a 15" Mitsubishi M80 Color LCD touchscreen, users can pinch to zoom in and out, scroll through screens, move popup windows on the screen, or drag with a single finger. The M80 also comes with two 32-GB SD card slots for memory expansion, USB program running and high-accuracy modes.
The V1320’s oversized, 45-mm double-nut ballscrews are fixed and pre-tensioned. The large, 45-mm linear guideways are supported by six trucks on the X and Z axes.The Y axis has dual 40-mm ballscrews.
The machine has a Big Plus, 40-taper, 12,000-rpm direct-drive spindle powered by a dual-wound Mitsubishi spindle motor. A quad set of 70-mm angular contact bearings and a 60-mm rear taper roller bearing provide thermal stability, radial and axial stiffness, and high accuracy as well as 900 kg tool retention force for aggressive cutting applications.
You know how to machine metals, but what about plastic machining? More specifically, glass-fiber-reinforced plastic? This machine shop has it figured out.
Lockheed Martin’s precision machining of composite skin sections for the F-35 provides part of the reason why this plane saves money for U.S. taxpayers. That machining makes the plane compelling in ways that have led other countries to take up some of the cost. Here is a look at a high-value, highly engineered machining process for the Joint Strike Fighter aircraft.
While aluminum molds are commonly used to create prototypes or to serve as stopgap bridge tooling, they are starting to receive greater attention for production work. This shop’s approach to creating aluminum molds in one day to three weeks is the same for each of these situations.
