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 SUPER HEAVY PLANER MILLING/GRINDING MACHINES
Main transmission of this series products adopts SRD or servo system,wide range of speed change(stepless is possible) 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 between light & heavy-duty machines, and the material is cast iron (≥HT250),so the machine is with better stability & accuracy retentivity. |
