摘要
數(shù)控加工中心是目前世界上產量最高、應用最廣泛的數(shù)控機床之一。它的綜合加工能力較強，工件一次裝夾后能完成較多的加工內容，加工精度較高，就中等加工難度的批量工件，其效率是普通設備的5～10倍，特別是它能完成許多普通設備不能完成的加工，對形狀較復雜，精度要求高的單件加工或中小批量多品種生產更為適用。
JCS-018型立式加工中心是一種工序高度集中，自動化程度高的機電一體化設備。工件在一次裝夾后，可連續(xù)地進行銑，鉆，鏜，鉸，攻螺紋等多種工序的加工。該機床適用于小型板件，盤件，殼體件，模具和箱體件等復雜零件的多品種，小批量加工。??主軸是主軸箱的重要組成部分。它的結構尺寸和形狀、制造精度、材料及其熱處理，對主軸箱的工作性能有很大的影響。為了提高主軸的剛度和便于安裝，將JCS—018立式加工中心的主軸設計成階梯圓柱形，前端外徑大，后端外徑小，為實現(xiàn)更換刀具時能自動夾緊，主軸內部設計成空心。
Z向工作臺的設計主要是對滾珠絲杠和直線導軌的設計，在計算設計過程要通過剛度，扭矩和載荷等條件來選擇相應的零件型號和尺寸。BF-3系統(tǒng)是功能比較簡單的標準型數(shù)控系統(tǒng)。該系統(tǒng)采用8086微處理器芯片，8284時鐘發(fā)生器，總線控制器8288，中斷控制器8259，串行接口8251A，可編程計時器8253，ROM，RAM以及緩沖器，譯碼器等電路，此外還有一些專用芯片。

Abstract
CNC Machining Center is the world's highest yield, the most widely used one of CNC machine tools. It's comprehensive processing ability, the workpiece can be completed after a single setup process more content, higher precision, the difficulty to medium batch processing jobs, and its efficiency is the common equipment 5 to 10 times, in particular, it can be completed many common processing equipment can not be completed on more complex shapes, high precision single piece or small batch processing of many varieties produce more applicable. JCS-018 Vertical Machining Center is a highly centralized process, a high degree of automation, electromechanical integration equipment. After the workpiece in a fixture can be continuously milling, drilling, boring, reaming, tapping and other machining processes. The machine is suitable for small plates, plate pieces, shell parts, molds and complex parts such as cabinet fittings and more variety, small batch processing. Spindle is an important part of the headstock. Size and shape of its structure, manufacturing precision, material and heat treatment, the performance of the work of the headstock has a great influence. In order to improve the stiffness of the spindle and easy to install, the JCS-018 vertical machining center spindle designed to step cylindrical, large diameter front end, back-end small diameter, for the realization of the tool can automatically replace the clamp, the spindle into the interior design hollow. Z key to the design table is the design of ball screw and linear guide rail, through the design process in the calculation of stiffness, torque and load conditions to select the appropriate type and size of parts. BF-3 system is a relatively simple function of the standard CNC system. The system uses 8086 microprocessor chip, 8284 clock generator, bus controller 8288, interrupt controller 8259, serial interface 8251A, programmable timer 8253, ROM, RAM, and buffers, decoders and other circuits, in addition to There are some special chips.
