本機床主拖動采用開關磁阻調速系統（SRD）或伺服系統，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 HEAVY GANTRY PLANER MILLING MACHINES

Main transmission of this series products adopts SRD or servo system,wide range of stepless speed change of the table's movement satisfies the requirements of planing/milling/grinding at different speed, independent spindle feeding box enables more balanced feeding 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.
