MK2110B 数控内圆磨床

机床的主要特点 Main Characteristics

o机床床身采用优质铸件浇铸,刚性好,结构稳,变形小;
o机床采用床头箱固定在进给滑板上工件进给,砂轮作往复结构布局;
o工件进给滑板及砂轮工作台滑板采用高刚度十字交叉滚柱导轨;
o工件进给由伺服电机经联轴器带动高精度滚珠丝杆副来实现,进给和补偿为同一传动链,结构紧凑,精度高;
o砂轮工作台采用模块化设计,油缸驱动快趋、快进往复,磨削为砂轮高频率机械振荡,振荡速度变频调速,提高磨削效率。
o工件主轴采用整体套筒式主轴,刚性好,主轴轴承采用高精度成对轴承,回转精度高,稳定性好,主轴回转变采用频无级调速;
o采用超宽的工作台和进给滑板结构,提高机床的整体刚性;
o机床配有防水全封闭罩壳,观察窗保证长期观察清晰,耐油污并保证砂轮破碎后不飞溅伤人;
o机床采用后置电器箱和前置回转式操作台以及独立的循环启动按钮。电箱带热交换器,以及确保在高温期间正常运行;
o机床可据加工零件设计制作专用夹具;
o机床采用日本三菱PLC控制系统、伺服单元及主要电器控制元件,用户如有特殊要求可选用其他控制系统;
o机床磨削冷却和电主轴冷却分别采用冷却系统;电主轴冷却功能带断水保护。
o数控内圆磨床MK2110B是模块系列产品,可据用户需要制成:
单轴:数控进给+液压快趋+机械振荡往复
机床型号:MK2110B/1
双轴:数控进给+数控往复
机床型号:MK2110B


oThe machine bed adopts the casting piece with the features of good rigidity and small deformation.
oThe headstock is fixed on the feed slide for achieving work feed. The gri. wheel reciprocation is also used.
oWork feed guideway and gri. wheel worktable guidaway adopt the crossed roller type.
oWork feed can be performed by the servo motor through the coupling via high-precision ball leadscrew pair.
oThe oil cylinder is used to drive the worktable to achieved gap elimination and rapid advance reciprocation of workpiece.
oTable reciprocation movement can be achieved by mechanical oscillation which its reci. speed is adjusted by the freq.-conversion speed regulator.
oCartridge-type work spindle is used. The high-precision matched spindle bearing is adopted with the features of high rotating accuracy and good reliability.
oSuper-wide worktable and feed slide are used, thus improving good rigidity. It's totally encloscd with guards to prevent swarfs from splashing.
oThe rear-mounted electrical cabinet and front-mounted control cabinet are also used. The heat-exchanger in the electrical cabinet is also provided.
oThe special fixture can also be designed according to the machined workparts.
oMitsubishi PLC control system a& servo unit is adopted. Other control system can also be seleted for special order.
oThe grinding cooling system is adopted. Independent coolant tank can be used for cooling the electric spindle with water-break proiection.
oAccording to requirements of user, this machine can be designed as below: One-axis CNC feed + hyd. gap elm. + mechanical osci. reciprocation Machine model: MK2110B/I
Two-axis CNC feed + CNC reciprocation Machine model: MK2110B
