Distributed by CNC Systems, Vision Wide’s SF series bridge mills feature additional Y-axis options of 47", 63" and 78". The X-axis selection ranges from 80" to 162" and the Z axis measures 31.5". The narrower Y-axis machine has roller linear ways on the X and Y axes for faster feed and rapid traverse rates. It also features a rigid Z axis with boxway construction.
Options include a 6,000-rpm, 35-hp spindle with a two-speed headstock; a 10,000-rpm direct-drive spindle that is directly coupled to the spindle motor for additional rigidity, acceleration and deceleration; and a 20,000-rpm direct-drive spindle for mold and die applications.
The machines are equipped with a 40-tool ATC and a fast cam-type ATC that changes tools in 3 sec. Other features include full coolant-through-spindle capability (300 psi), a spindle chiller and ballscrew support systems on machines 160" (4 m).
The bridge mills feature a heavy-duty casting; large supporting columns; a cross beam; a step square beam; and a saddle. The table is ground for accuracy and longevity. The Z axis has a self-aligning, twin hydraulic counter-balance system that ensures high speed movement without excessive loads on the axis and motor, the company says.
Other features include a Fanuc 18i MB control; spindle and gear box cooling; independent lube in the X, Y and Z axes; a full splash guard; an air blast through spindle; and flood coolant.
You know how to machine metals, but what about plastic machining? More specifically, glass-fiber-reinforced plastic? This machine shop has it figured out.
... not to mention grinding with air. Thanks to high speed spindles powered by shop air, this job shop expands the work its VMCs can do.
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.
