本机床主拖动采用开关磁阻调速系统(SRD),工作台往复运动可以实现无级调速,其宽大的调速范围可满足刨、铣、磨的各种速度要求。刀架进给运动有独立进给箱,使进刀更均匀,可以加工各种材质的平面、斜面、T型槽、组合导轨和齿条等。
1、多头蜗杆拖动高精度齿条,工作台运动更平稳。
2、独立的工作台润滑系统,使工作台在各种速度下都能得到充分润滑。
3、床身、立柱等关键件的回火、震动时效、超音频淬火等热处理工艺,使机床精度更稳定、使用寿命更长。
4、机床床身、立柱、横梁和工作台根据重型机床参数设计,材料采用HT250以上铸铁铸造,使机床具有更好的稳定性和精度保持性。
BXM20 SERIES OF HEAVY-DUTY PLANER-TYPE
PLANING/MILLING/GRINDING MACHINES
The main transmission of this series products adopt SRD,wide range of stepless speed change of the table’s movement of can satisfy the requirements of planing/milling/grinding at different speed, independent spindle feeding box enables more balanced feedinging to process plane/inclined plane/T slot/combined guideway/rack,etc.
1.To drag high-precision rack with 9-head worm to realize more stable table movement.
2.To get enough lubrication of table at any speed with independent lubrication system.
3.The adoption of heat-treatment techniques like drawing the temper off/quiver-ageing/hyperacoustic quenching on key parts as the machine body/column enables more stable accuracy and longer working life.
4.Machine body/column/beam/table are designed according to the parameters of heavy-duty machines, and the material is cast iron (≥HT250),so the machine is with better stability & accuracy retentivity.
