产品详细说明

MKG28系列数控高精度立式万能磨床采用西门子交流伺服驱动,五轴控制,两两联动,可用于大中型回转体类零件的精密加工,如高圆度、高尺寸精度的精密主轴套筒;适用于大中型零件的精密加工,如高同心精度和高垂直精度的大型轴承的内外套圈;高平行精度的隔圈;大中型内外轮廓曲线的加工。

MKG28 series high-accuracy numerical-controlled universal vertical grinder is driven by Siemens alternate current servomotor and controlled by five axes of which every two is simultaneously. The grinder can be used in precision finishing of large or medium parts of rotation, such as precision shaft sleeve of high roundness and accuracy, such as large and high precision bearing ring, and high parallelism spacer, as well as machining of large and medium internal and external profile curve.

l 机床采用立式布局,便于大中型工件的装卡与找正。

l 采用西门子840D数控系统,五轴控制,两两联动;

l The vertical machine makes it easy for mount and alignment of large or medium workpieces.

l Siemens 840D Numerical Control System works with five axes and every two axes is simultaneously.

l 采用专利技术的静压回转工作台,具有高精度.高刚性.高承载力.高定位精度.长使用寿命等特点.径向跳动和轴向窜动≤1μ;工作台外沿1米处端面跳动≤1μ;该工作台具有C轴数控分度功能,由大功率力矩电机直接驱动,配备德国海德汉精密圆光删,实现角度闭环控制,可对零件内外轮廓曲线进行加工,重复定位精度达到1角秒;

l The patented hydrostatic rotary table has high precision, high rigidity, high capacity, high positioning accuracy and long service life. Radial and axial runout are equal to or less than 1μ, the face runout at the maximum diameter is equal to or less than 1μ. In order to possess the c-axis CNC dividing function, the worktable is directly driven by a torque motor with large moment, and it is equipped with Heidenhain high-precision radial grating to realize the closed-loop control and could to machine internal and external curves of parts with 1 arc second of repeat location accuracy.

l 砂轮主轴采用专利技术的动静压主轴,具有高精度.高刚性.高加工效率.长使用寿命等特点,主轴的径向跳动和轴向窜动≤1μ;

l 该机床加工工件圆度≤1μ,实测为≤0.5-0.7μ;加工工件表面光洁度Ra≤0.1μ,实测为Ra≤0.08μ.该加工精度达到甚至已超过国际同类产品

l The grinding wheel spindle has patented hydrodynamic-static bearing, having high precision, rigidity, machining efficiency and long service life, and its radial and axial runout are equal to or less than 1μ.

l Roundness of manufacturing workpiece should be equal to or less than 1μ and actual measurement be equal to 0.5-0.7μ; surface finish of manufacturing workpiece should be equal to or less than 0.1μ and actual measurement be equal to 0.08μ. The machining accuracy has reached even surpassed that of similar products at home and abroad.

l 该机床一次装夹可以实现零件上的内圆表面、外圆表面、端面、内外台阶面、内外锥面、内外曲线表面等的精密加工。

l 机床可选配车削附件,可对零件里孔.外圆.端面进行精密车削,去除过多的余量,提高机床的工作效率.

l 机床可选配铣床附件,可对零件进行复合加工.

l The precision machining of inner surface, outer surface, end surface, internal and external step surface, internal and external conical surface and internal and external curve surface of parts through one chuck.

l Turning accessories can be equipped optionally with a single point tool to turn inner hole, external cylinder and end surface to get rid of overfull margins and improve working efficiency

l Milling accessories can be equipped optionally with a cutter to fulfill composite machining of parts.

l 配备意大利进口电控永磁吸盘,吸力可调。装卸工件无需扳手,按钮控制,加工完毕自动退磁。显著地提高了机床的利用率并改善了工人的劳动条件。

l 整体结构设计及配置符合国家环保及节能的标准

l 机床主轴系统配有进口消除空程装置,有效提高机床加工效率.

l 机床采用控温大流量和两级过滤冷却系统,保证机床加工中热稳定性及加工精度.

l The machine is also equipped with an electrical- permanent magnetic chuck, imported from Italy, and its suction is adjustable. No spanner is needed when loading and unloading the workpieces, you just need to press the button. The chuck can demagnetize automatically after machining completed. These characters can improve utilization rate of the machine tool and working conditions of workers.
