CX300-40数控机床特点：
1.床脚整体结构一体化设计制造，采用树脂砂铸造，经时效处理变形小，具有很高的稳定性和刚性;
2.采用线轨，导向性和刚性更好，精度及精度保持性较好;
3.采用全封闭式防护罩，极大的延长机床各配件的使用寿命，确保机床的高精度;
4.主轴采用主轴单元并经过动平衡处理,提高主轴转速和改善加工
零件的粗糙度。
1. The overall structure of the bed foot is designed and manufactured in anintegrated manner, using resin sａnd casting, with small deformation afteraging treatment, and high stability and rigidity;
2. The use of linear rails has better guidance and rigidity, and better accuracyａnd precision retention;
3. Fully enclosed protective cover is adopted to greatly extend the servicelife of various parts of the machine tool and ensure the high precision of themachine tool;
4. The main shaft adopts the main shaft unit and undergoes dynamic balancetreatment to increase the speed of the main shaft and improve theroughness of the processed parts.
