本機(jī)床的萬能性好，適合大批量生產(chǎn)粗、精加工中、重型卡車、礦山機(jī)械、工程機(jī)械、船舶齒輪。

本機(jī)床采用西門子828D數(shù)控系統(tǒng)和交流數(shù)字伺服系統(tǒng)，具有三個(gè)數(shù)控軸：工件（Y軸）、搖臺（X）軸、床鞍（Z軸），可實(shí)現(xiàn)三軸聯(lián)動，刀具主軸（S軸）采用交流變頻調(diào)速，使機(jī)床無需改變?nèi)魏螔燧喛蓪?shí)現(xiàn)切削運(yùn)動，操作更方便，柔性強(qiáng)，使只具有機(jī)械銑齒機(jī)操作調(diào)整經(jīng)驗(yàn)的人員能將常用的YT2250（或Y225）、Y2280等機(jī)床調(diào)整卡的有關(guān)參數(shù)轉(zhuǎn)換為本機(jī)床的相應(yīng)參數(shù)使用。

二．機(jī)床主要特點(diǎn)：

采用交流變頻電機(jī)作主驅(qū)動動力源，而搖臺和工件主軸都由伺服電機(jī)驅(qū)動，床鞍進(jìn)給由伺服電機(jī)通過滾珠絲杠驅(qū)動，簡化了傳統(tǒng)的機(jī)械結(jié)構(gòu)，無需更換掛輪減少了機(jī)床調(diào)整時(shí)間，縮短了傳動鏈，不但提高了機(jī)床精度，而且使操作更為準(zhǔn)確、方便。本機(jī)床可配置安全防護(hù)罩和自動排屑器。機(jī)床的密封電氣控制柜可配置空調(diào)。

Ⅰ. Applications of Machine

  Model YKD2280 machine is a precision CNC Spiral Bevel Gear Generator, which is designed for roughing and finishing Spiral Bevel Gears and Hypoid Gears and Equidepth gears of the Gleason system with the diameter up to 800mm and module 15mm.

  On this machine, the cutter is mounted on the cradle (circular guideway). The integral structure is rigid, highly accurate and working stably. The cradle-type gear cutting machine, which is also possible for hard surfacing, is durable and the service life will be several dozens of years under normal operating conditions.

  The machine is with universal features and it is suitable for roughing and finishing, in mass production, gears used for medium & heavy load trucks, mining machineries, construction machineries and shipbuilding industry.

  The machine is equipped with a CNC control system 828D (SIEMENS) and designed to operate as a three-axis machine, i.e. cradle rotation (X axis), work spindle rotation (Y axis) and sliding base movement (Z axis) being simultaneously controlled by the CNC control system to cut gears. The rotation of cutter spindle (S axis) is controlled by an A.C. frequency-variable motor for its stepless control. Therefore, no change gears will be used on the machine for cutting gears. The machine operation is easy and flexible.  The clients who have the conventional machines can convert the machine settings used for YT2250 (or Y225) and Y2280 machines into the machine settings for the YKD2280 machine.

Ⅱ. Main Features of Machine        

  An A.C. frequency-variable motor is used as a main driving power source while the cradle rotation and work spindle rotation are driven by the servo motors. The sliding base movement is driven by a servo motor through a ball screw.  All of these features of the machine are for the purpose of simplifying the conventional mechanical structure, reducing the machine setup time and shortening the transmission train because of the change gears elimination.  In this case, not only the machine accuracy is increased, but also the operation is easy and convenient.  Safety guards and an automatical chip conveyor may be provided on the machine. The machine is equipped with a sealed electrical cabinet which is with an air conditioner.

Ⅲ. Power Supply: 380V, 50 HZ

Ⅳ. Main Electrical Parameters:

   A.C. Frequency-variable Motor (main drive)        15KW, 1500rpm

   Servo Motors (cradle & workhead)                42NM, 1500rpm

   Servo Motor (sliding base movement)             23NM, 2000rpm
