本機床主拖動(dòng)采用開(kāi)關(guān)磁阻調速系統（SRD）或伺服系統，工作臺往復運動(dòng)可以實(shí)現無(wú)級調速，其寬大的調速范圍可滿(mǎn)足刨、銑、磨的各種速度要求。刀架進(jìn)給運動(dòng)有獨立進(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、組合導軌和齒條等。
1、多頭蝸桿拖動(dòng)高精度齒條，工作臺運動(dòng)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(guān)鍵件的回火、震動(dòng)時(shí)效、超音頻淬火等熱處理工藝，使機床精度更穩定、使用壽命更長(cháng)。
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 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. |
