Makino’s F series VMCs are designed to provide stiffness and rigidity for chatter-free cutting; agility for high-speed/hard-milling; and accuracy for tight tolerance blends and matches typical of complex, 3D contoured geometry associated with die/mold and medical production.
The machine’s axis configuration has no overhangs. Other features include large castings; 8-mm, fine-pitch ballscrews; and 0.05-micron scale feedback.
The series consists of two models: the F3 and the F5. The smaller F3 features X-, Y- and Z-axis travels of 25.6", 19.7" and 17.7", respectively, a 33.5" × 19.7" table and a maximum workpiece size of 33.5" × 19.7" × 17.7". The larger F5 features X-, Y- and Z-axis travels of 35.4", 19.7" and 17.7", respectively, a 39.4" × 19.7" table and a maximum workpiece size of 39.4" × 19.7" × 17.7". Both have a table load capacity of 1,432 lbs and a 30-tool magazine.
The 20,000-rpm, HSK-63A spindle incorporates the company’s patented core-cooling, under-race and jacket spindle temperature control system. The two-range spindle is designed for stiffness and rigidity at lower ranges for roughing operations, as well as chatter-free use of small tools at high rpm for production of small details and fine features.
The series utilizes the Professional 5 control. According to the company, the control blends a Windows CE graphical user interface (GUI); touchscreen selection; user-friendly, efficient, PC-like capability for data management and editing; and the networking and storage capability of a data center.
The machine is also equipped with the company’s Super Geometric Intelligence (SGI.4) software, which is designed for high-feed, tight-tolerance machining of complex, 3D contoured shapes that involve continuous, tiny blocks of NC data.
