High Precision 5-Axis Machining Center
January 1, 2020
The new Akira Seiki 5AX-AC650-5 vertical machining center (VMC) has been added to the company's high precision VMC lineup. It incorporates a large 19.67" diameter trunnion rotary table with an A-axis range of 120 +30° and a C-axis range of 360°. The rotary table's maximum load is 450 lbs. with a maximum part size of 21.0" by 14.0" (diameter x height).
The 5AX-AC650-5 has axes travels of 31.7" x 23.2" x 22.1" (XYZ). It is powered by a 30 HP, 12,000 RPM spindle with an optional 15,000 RPM spindle. The automatic side mount tool changer has 28 tool positions with an option for 36 tools. The standard 4 +1 axis configuration can be upgraded to a true simultaneous 5-axis configuration, utilizing either the Mitsubishi 830 or FANUC CNC controls. Rapid traverse rates are 1,500 IPM (X, Y, Z). The maximum cutting feedrates are up to 800 IPM (XYZ). "The 5AX-AC650-5 is extremely accurate with positioning accuracies of .00016 and repeatability of .00008 (XYZ axes)," said a company spokesperson.
Other key features include:
- Mitsubishi 830 or FANUC CNC controls with high speed look ahead, color LCD and rigid tap
- High torque digital drives with AC brushless motors (Mitsubishi or FANUC drives)
- A long nose spindle design is used to keep the headstock clear of specialized work fixtures and to allow cutting of intricate cavity configurations
- The tool changer is of the reliable side mount arm type for fast chip free tool changes
- Precision ground linear ways provide high speed machining with enhanced finishes
- Fully enclosed sheet metal guards aid in containment of chips and coolant
- Heavily ribbed Meehanite castings are utilized on bed, column and saddle to provide high rigidity for high speed cutting, high accuracy and longevity with optimal thermal stability.
