Archimdes spiral cam and equant shape could be machined by vertically installed CNC rotary table Spin table (Oprional) is designed for rotary workpiece with non-linear generatrix Large power grinding head is provided for heavy grinding. Carbide miller(max. diameter 10) could be mounted on grinding head for light milling. Max. milling depth is 0.3mm. 主 要 特 点 当采用下列附件时可以扩大加工范围： 使用45角度板可以磨削内外球面（不超过半个球 面） 。 使用磨槽附件可以磨削键槽及尺寸大于4040(长宽) mm的方孔。 使用可调角度板可以利用圆柱砂轮磨削锥孔。 使用圆弧砂轮修整器可以修整磨槽附件的砂轮，供成 形磨削及外轮廓的磨削。 使用数控转台，在卧式安装时，可用来加工鼓形凸轮， 在立式安装时可用来加工阿基米德螺旋线凸轮及等分 图形等。 使用自旋工作台(特殊订货附件)，可用来加工母线为非 直线的回转体零件。 机床备有低速大功率磨头，可进行强力磨削，当在该 磨头上装上硬质合金铣刀(最大铣刀直径为10)可进行 轻微的铣削工作.最大切削深度为0.3mm。 Main features 机床MK2945C第0008号 Y轴 定位精度双向Au=5.7m 重复定位精度R=1.2m 机床定位 精度检测采用国家标准J JB B/ /T T6 66 60 02 2- -9 93 3 ( (等同于 V VD DI I 3 34 44 41 1) ) Positioning accuracy is measured as per ISO standard JB/T6602-93 (similar to VDI 3441) 机床MK2945C第0008号 轴 定位精度双向Au=3.2m 重复定位精度R=1.7m 定位精度检测曲线图 Curve of positioning accuracy 导轨 整机及附件设计时考虑以湿磨为主，这样可以减少粉尘污染，同 时也有利于磨削陶瓷零件。机床定位精度检测采用JB/T6602-93标准 （等同于VDI3441) These machines together with their attach-ments are designed for wet grinding operation mainly to eliminate dust-pollution,and is also helpful for ceramic material grinding. 环 保 Environment protecting MK2945C MK2945C MK4280总体布局为双柱定梁龙门式机床。床身为刚性极好的箱式结构。主 柱在横梁上左右移动，主轴箱沿立柱导轨可以作上下移动。床身和横梁的刚性 极好，保证了X、Y、Z轴的高定位精度。 机床的Z轴与U轴联动进行锥度磨削，操作更方便。Z轴采用电 器伺服控制，因此具有反向精度高的特点。 Double column, fixed beam gantry structure. Box type machine bed with excellent rigidity. Column moves along fixed beam and headstock move up/down along column guide-way. Good rigidity of machine bed and beam ensure high positioning accuracy of X, Y-axis. Z and U axis could be simultaneously controlled to perform taper grinding. Z-axis is servo controlled and features high reverse accuracy. 机 床 结 构Structure 结构特点 Features 机床床身、立柱、滑动工作台均采用高质量的密烘铸铁， 套筒支承采用特制的自循环直线 滚动轴承，轻便、灵活、精度保持长久 A self-cycling linear rolling bearing is for the quill support to feature light and sensitive movement, and to keep long-lasting accuracy. 主轴 套筒 Spindle and Quill “U轴”采用本公司专利结构。可自动修正、 自动补偿砂轮。 U-axis construction is our patent design with automatic wheel dressing and compensation U 轴 U-axis 主轴轴线热稳定装置 Thermal stablilzer for spindle axes NINGJIANG MACHINE TOOLS 立柱采用整体箱式结构，具有最佳热对称性和结构稳定性。 立柱内部设有平衡磨头箱的两只并联气缸，保证了磨头 箱移动可靠、灵敏，同时也延长了W向导轨的使用寿命。 Machine body,column and sliding worktable are made of high quality meehanite metal,and a one-piece box column design features optimal thermal-symmetry and structural stability. Two parallel cylinders builtin the column are for balancing spindle housing to ensure its movement reliability and sensitivity,and meantime extend service life of W axis guideway. “C轴”为跟踪轴，操作者只需照看一下进刀，而无需 刀具半径补偿和刀具偏置。因此，调整方便。利用“C轴” 功能，操作者可在机床上对所磨削的工作进行检测。 C-axis is a follow-up axis which can provide convenient operation as no tool compenstion and tool radius offset are needed ,and only wheel feed is taken care of.With C-axis function, the ground workpiece can be measured directly on the machine. 轴 C-axis 立卧两用回转工作台用于磨削凸轮、叶片等回转体 零件。 由于Z轴采用伺服电机控制，磨轮下反向点精度为 0.05mm，因此可以磨削台阶或盲孔。 （MK2932B除外） 。 H/V rotary table is used to grind such rotary parts as cams and blades. Tolerance on down reversing point is within 0.05mm because servo-motor is used to control Z-asis, so shoulders and blind holes can be ground on the machine (except Model MK2932B). 轴 (选购) A-axis(opt.)
