本機床主拖動采用開關磁阻調速系統（SRD），工作臺往復運動可以實現無級調速，其寬大的調速范圍可滿足刨、銑、磨的各種速度要求。刀架進給運動有獨立進給箱，使進刀更均勻，可以加工各種材質的平面、斜面、T型槽、組合導軌和齒條等。
1、多頭蝸桿拖動高精度齒條，工作臺運動更平穩。
2、獨立的工作臺潤滑系統，使工作臺在各種速度下都能得到充分潤滑。
3、床身、立柱等關鍵件的回火、震動時效、超音頻淬火等熱處理工藝，使機床精度更穩定、使用壽命更長。
4、機床床身、立柱、橫梁和工作臺根據重型機床參數設計，材料采用HT250以上鑄鐵鑄造，使機床具有更好的穩定性和精度保持性。
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.
