Features:
1. Basic parts made of cast iron in high quality & high strength， high pressure molding for large parts enables machine in good rigidity，good aseismicity & good precision retaining ability.
2. Gantry type frame structure，mobile table，compact structure of whole machine，scientific layout，elegant appearance.
3. Heavy duty linear rolling guide-way in axis X/Y with advantage of big load，high precision. Hard guide-way in Z，self-poise system of symmetrical double oil cylinder in spindle box ensures rigidity & precision of feeding in Z.
4. Famous high speed spindle unit，speed change mechanism of it fits strong cutting at low speed.
5. Widely used in fine machining in industries like molding industry，automobile industry，aerospace industry，engine industry，packing industry，textile industry and so on. Fit for machining requirements on procedures such as milling，boring，drilling，tapping，etc.
