1.The machineintegrates functions ofmilling, boring, drilling (drilling, expanding,reaming),tapping.
2.The international CNCnumerical control system is adopted.
3.It is suitable for processing oflarge parts, plate parts, disc parts, shell partsmolds and other precision parts.
4.Features of high precision, high speed, high flexibility and environmental protection.
5.The X-axis is supported by four rolling guide rails, and the Z-axis adopts a squareram structure constrained by four sides, with excellent machining rigidity.
6.Z-axis feed is driven by double motors and double screws, with betterinertiamatching and dynamic response.
7.It is widely used in the industries ofshipbuilding, power generation, heavymachinery,locomotive,textile machinery, printing machinery, moldmanufacturing,etc.
