The RFMV80 CNC vertical machining center,
using linear rolling guide ways, is one in a family of RIFA built VMCs. The
machine has 7000 rpm spindle speed and 24m/min rapid traverses. The X, Y, Z
axis range is 800mm × 560mm ×600mm. A 1000mm×550mm T slotted table is included.
Features
1. The machine base, column, head and cross
slid carriage of the CNC vertical machining center are constructed from high
quality cast iron. The advanced machine construction, widened and fixed column
design provide added rigidity and durability. Finite element analysis
procedures are used to qualify the design.
2. Linear rolling guide ways are used for the X, Y and Z axis motions,
providing increased acceleration and deceleration rates.
3. Servos couple directly to the high precision ball screws of the CNC vertical
machining center, eliminating gears and preventing backlash and servo drag.
4. The pre tensioned ball screws provide increased rigidity and thermal
stability.
5. The spindle of the CNC vertical machining center is supported by six
precision class permanently lubricated bearings, which are true cartridge type
units. A refrigerated spindle cooling system circulates oil around the spindle
and bearings. This maintains constant temperatures across a range of ambient
and operating conditions. An encoder is mounted on the spindle, realizing rigid
tapping as well as accurate positioning.
6. A FANUC 0i MD control system is standard. MITSUBISHI control system is
optional.
