本機床主拖動采用開關(guān)磁阻調(diào)速系統(tǒng)（SRD），工作臺往復(fù)運動可以實現(xiàn)無級調(diào)速，其寬大的調(diào)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(zhì)的平面、斜面、T型槽、組合導(dǎo)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(wěn)。

2、獨立的工作臺潤滑系統(tǒng)，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(guān)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(wěn)定、使用壽命更長。

4、機床床身、立柱、橫梁和工作臺根據(jù)重型機床參數(shù)設(shè)計，材料采用HT250以上鑄鐵鑄造，使機床具有更好的穩(wěn)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 adopts SRD,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.
