本機(jī)床主拖動(dòng)采用開(kāi)關(guān)磁阻調(diào)速系統(tǒng)（SRD）或伺服系統(tǒng)，工作臺(tái)往復(fù)運(yùn)動(dòng)可以實(shí)現(xiàn)無(wú)級(jí)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(jìn)給運(yùn)動(dòng)有獨(dú)立進(jìn)給箱，使進(jìn)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(dòng)高精度齒條，工作臺(tái)運(yùn)動(dòng)更平穩(wěn)。
2、獨(dú)立的工作臺(tái)潤(rùn)滑系統(tǒng)，使工作臺(tái)在各種速度下都能得到充分潤(rùn)滑。
3、床身、立柱等關(guān)鍵件的回火、震動(dòng)時(shí)效、超音頻淬火等熱處理工藝，使機(jī)床精度更穩(wěn)定、使用壽命更長(zhǎng)。
4、機(jī)床床身、立柱、橫梁和工作臺(tái)根據(jù)重型機(jī)床參數(shù)設(shè)計(jì)，材料采用HT250以上鑄鐵鑄造，使機(jī)床具有更好的穩(wěn)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.
