What are the NC gantry milling suitable for external processing ?
分为横梁固定、横梁靠定位块锁定分段升降和横梁任意升降三种类型，滑枕从结构上可分为开式和闭式两种型式。 The gantry is composed of a beam and two columns. The external machining of CNC gantry milling is divided into three types: beam fixed, beam locked by positioning block, segmented lifting, and beam free lifting. The ram can be divided into open type and closed type. Two types.
The open structure of the ram is clamped on the headstock by the pressure plate. The cross section of the ram is large. The closed structure of the ram is clamped in the headstock. The cross section of the ram is small, and the basic type of the tool magazine is changed. There are three types: tower type, drum type and chain length type.
数控系统供应商很多，按照不同的需求系统品牌和型号有不同的选择。 Large and complex parts usually require a lot of attachment heads. The attachment heads are custom designed according to the processing requirements of the workpiece. They are generally divided into right-angle heads, extended heads, special angle heads, etc. There are many suppliers of CNC machining systems for CNC gantry milling , according to different needs. There are different options for system make and model.
The accuracy of the machine tool refers to the original size of the machine tool under the condition of no external load. It is usually expressed by the deviation between its reverse side and the ideal state. The smaller the error, the higher the accuracy. The gantry machining center refers to the spindle axis. The machining center is perpendicular to the workbench. The overall structure is a portal frame, which is composed of double columns and top beams, with a beam in the middle.
尤其适用于加工大型工件和形状复杂的工件，有定梁式、动梁式、动柱式、天车式也有以上复合形式的多类龙门加工中心，加工的特性、能力、针对的产品加工用途也不完全一样。 CNC gantry milling is especially suitable for processing large workpieces and complex shaped workpieces. There are fixed beam type, moving beam type, moving column type, and overhead crane type. There are many types of gantry machining centers with the above composite forms. Processing characteristics, capabilities, Targeted product processing applications are not exactly the same.
