FG Series Double-Column Type Vertical Machining Center
Model：FG-2220 / 2720 / 3220 / 4220L (LG)
To produce a high rigid machine tool, it needs to start from rigorous requirement of a small screw. With over 30 years of design and manufacturing experience, Chi-Fa's FG series double column machining center has been developed and manufactured in-house throughout the entire machine. Only with this way, we can fully understand how to optimize combination and running for the thousands of parts on a large machine tool, that also allow us to build the optimum machine structure.

Description
ㆍZ-axis is a box way design and sliding surfaces are precisely scraped to ensure the service life of the slide ways. The box ways and the ram are one-piece fabricated to achieve no clearance between the slideways and the saddle. This feature is normally requested by a high end machine.
ㆍClass C3 Ball Screws on Three Axes: Ball screws have been pre-tensioned to ensure machining accuracy under heavy loading condition for a long time.
ㆍTable, Spindle Head & Saddle: Manufactured from high quality Meehanite cast iron, they feature ultra high rigidity, excellent absorbing capacity and wear-resistance.
ㆍBase, Beam & Column: These structural parts are manufactured with multi-walls with internal rib, welded by high strength steel plates with tempered and stress-elieved. With the meticulous design, various structural parts will provide the best possible vibration absorbing performance and rigidity.
