机床的主要特点 Main Characteristics
• 机床导轨采用双V型预加负荷，高精度十字交叉滚柱滚动导轨，精度高，刚性好。
• 机床采用高速大功率电动砂轮轴，由静止变频器供电，能耗低，嗓音小。
• 进给机构采用三滚轮系统、液压控制、精度高。
• MD215A机床带有端磨装置，一次装夹可完成内孔及端面磨削，工件端面与内孔的垂直度。
• High precision preloaded dual-V cross rolling guideways are used to provide high accuracy good rigidity.
• Equipped with high speed and high power electric spindle powered by static frequency convertor,featuring low energy consumption and low noise.
• 3-roller system is used in feed mechanism which is controlled hyd raulically.thus providing high accuracy.
• Model MD215A Internal Grinders are also equipped with the endface grinding attachment, so that inner bore and endface grinding can be performed, thus guaranting perpendicula rity of work endface to bore.
