OKK VM940R VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a work table measuring 90.6" x 37" with X, Y, and Z travels of 81.10", 37.00", and 32.30" respectively, accommodating large workpieces and versatile machining tasks. The machine offers rapid traverse rates of 787 IPM on X and Y axes, and 630 IPM on the Z axis, with a maximum cutting feed rate of 787 IPM, enabling high-efficiency material removal. It is equipped with a robust 35 HP spindle motor capable of speeds up to 12,000 RPM. The spindle uses a CAT#50 taper, known for its rigidity and suitability for heavy-duty machining, ensuring stable tool holding under high cutting forces. Spindle nose to table clearance ranges from 7.9" to 40.2", allowing flexibility for varying workpiece sizes. Tool handling is facilitated by a 40-tool side-mount magazine with a rapid 2.9-second tool change time, enhancing productivity. The machine supports advanced coolant systems including a 30 HP chip blaster coolant system with thru-spindle coolant delivery and an air blow nozzle designed for dry cutting, promoting effective chip evacuation and thermal management. Chip removal is efficiently managed by an integrated chip conveyor system. Precision and automation are enhanced by a Renishaw OMP60 probe for part setup and in-process measurement, supporting high accuracy and repeatability. This configuration makes the machine suitable for demanding metal cutting operations, including aerospace, mold making, and other high-precision manufacturing environments.
