200/320 Series CNC cylindrical grinding machine is the kind of CNC cylindrical grinding with high-efficiency and high-precision, including cylindrical grinding,

and end face cylindrical grinding. 200 Series maximum machining diameter is 200mm, and the processing length contains 500 mmand 750 mm two specifications.

320 Series maximum machining diameter is 320mm, and the processing length contains 750mm,1000mm and 1500 mm three specifications.It is applicable to the

high efficiency grinding of mass cylinders’ excircles, shaft shoulders, and cones of multi journals. The CNC cylindrical grinding is controlled by two axis digital control

system. The machine owns the functions like automatic axial positioning, grinding wheel automatically cut-in, workbench automatically jump, automatic size

measurement, two-axis automatic dressing of the grinding wheel and automatically compensate for grinding wheel after the modification, wheel grinding with

constant linear velocity, and so on. The machine equipped with imported original CNC system.

精磨时选择适当的砂轮十分重要,针对模具钢材的高钒高钼状况,选用GD单晶刚玉砂轮比较适合,当加工硬质合金、淬火硬度高的材料时,优先采用有机粘结剂的金刚石砂轮,有机粘结剂砂轮自磨性好,磨出的工件粗糙度可达Ra0.2μm,近年来,随着新材料的应用,CBN(立方氮化硼)砂轮显示出十分好的加工效果,在数控成型磨床、坐标磨床、CNC内外圆磨床上精加工,效果优于其它种类砂轮。在磨削加工中,要注意及时修整砂轮,保持砂轮的锐利,当砂轮钝化后,会在工件表面滑擦、挤压,造成工件表面烧伤,强度降低。

φ500/φ630/φ800 系列数控外圆磨床采用后置移动结构形式，既砂轮架沿头架、尾架主轴中心线平行移动及砂轮架沿头架尾架主轴中

心线成垂直角前后移动；此结构形式减少了采用工作台移动的结构形式时，因工件重量的变化而造成工作台导轨的微量变化，从而影响工

件磨削精度的弊端；具有移动部件质量轻、质量变化小，运动部件惯性小，高效节能等优点。

φ500/φ630/φ800 series CNC Cylindrical Grinding Machine adopts the form of rear moving structure, both the sand wheel frame moves parallel along

the head frame and the tail frame spindle center line and the wheel frame moves forward and backward into the vertical angle along the tail frame spindle

center line. This structure form reduces the variation of the guide rail due to the change of the workpiece weight when the worktable is moved, which affects

the workpiece grinding precision. It has the advantages of light moving parts, small quality change, small inertia of moving parts, high efficiency and energy

saving.  

第一个是合理选择和修整砂轮,采用白刚玉的砂轮较好,它的性能硬而脆,且易产生新的切削刃,因此切削力小,磨削热较小,在粒度上使用中等粒度,如46~60目较好,在砂轮硬度上采用中软和软(ZR1、ZR2和R1、R2),即粗粒度、低硬度的砂轮,自励性好可降低切削热。精磨时选择适当的砂轮十分重要,针对模具钢材的高钒高钼状况,选用GD单晶刚玉砂轮比较适合,当加工硬质合金、淬火硬度高的材料时,优先采用有机粘结剂的金刚石砂轮,有机粘结剂砂轮自磨性好,磨出的工件粗糙度可达Ra0.2μm,近年来,随着新材料的应用,CBN(立方氮化硼)砂轮显示出十分好的加工效果,在数控成型磨床、坐标磨床、CNC内外圆磨床上精加工,效果优于其它种类砂轮。在磨削加工中,要注意及时修整砂轮,保持砂轮的锐利,当砂轮钝化后,会在工件表面滑擦、挤压,造成工件表面烧伤,强度降低。 机床工具行业39种：分三种情况，北京外圆磨床厂家直销,数控磨床，1.加工中心和数控的卧式车床、钻床、镗床、镗铣床、升降台式铣床、平面磨床、外圆磨床、齿轮加工机床、电加工机床、锻造或冲压机床、矫直机床、折弯机床、剪切机床、冲孔机床，协定税率都为5%，比我国现行税率9.7%，低4.7个百分点。2.非数控的车床、铣床、磨床、拉床、锯床、锻造或冲压机床，北京广宇大成数控机床有限公司,广宇大成数控机床,协定税率都为10%，北京外圆磨床厂家直销,磨床，北京外圆磨床厂家直销,高精度磨床，比我国现行税率12%，低2个百分点。3.工具、夹具、分度头及其他机床附件、金属成形加工机床零件、千分尺、卡尺及量规，协定税率都为5%，比我国现行税率低1~3个百分点。
