The transmission accuracy and smoothness of gears ground on this machine will be improved tremendously.

二．機(jī)床的主要性能和結(jié)構(gòu)特點(diǎn)

   1．本機(jī)床由八個(gè)主要部件組成：床身，搖臺(tái)，砂輪架，床鞍；工件箱，主驅(qū)動(dòng)，床鞍進(jìn)給機(jī)構(gòu)，液壓傳動(dòng)系統(tǒng)。砂輪緊固在砂輪架主軸上，移動(dòng)砂輪架，砂輪在對(duì)工件的一定位置上可調(diào)整。工件緊固在裝入工件箱主軸的芯軸上，借助液壓夾緊夾頭緊固。在床鞍上回轉(zhuǎn)工件箱可實(shí)現(xiàn)被加工零件的根錐角，及調(diào)整工件箱水平位置來(lái)確定工件的輪位。此外，在某些情況下使床鞍對(duì)中心位置向前或向后移動(dòng)滿足床位要求。

   2．機(jī)床上裝有砂輪修整裝置。借助兩金剛筆（一支修齒形用，而另一支修砂輪的頂圓）注意所需要的過(guò)凹部倒圓半徑的值修整砂輪。

   3．機(jī)床還可通過(guò)機(jī)械機(jī)構(gòu)修正裝置加工鼓形齒頂及齒根修緣。機(jī)床能以數(shù)控程序自動(dòng)周期進(jìn)行工作，此時(shí)，除上，下工件外，全部工序都自動(dòng)進(jìn)行。

   4．本機(jī)床由五個(gè)傳動(dòng)軸組成，并采用德國(guó)西門(mén)子（SIEMENS）公司的828d數(shù)控系統(tǒng)實(shí)現(xiàn)（搖臺(tái)分度，工件箱分度及床鞍絲杠）3聯(lián)動(dòng)的運(yùn)動(dòng)控制，通過(guò)人性化磨削軟件包實(shí)現(xiàn)機(jī)床的自動(dòng)調(diào)整，磨削軟件操作簡(jiǎn)單，使用方便。

   5．機(jī)床加工齒的一邊，因此加工齒輪的另一面，則可通過(guò)旋轉(zhuǎn)搖臺(tái)實(shí)現(xiàn)。因?yàn)楸緳C(jī)床是剛性強(qiáng)，行程快的機(jī)床，在機(jī)床上可用現(xiàn)代化的磨削規(guī)范，并提供紙帶過(guò)濾，恒溫油箱（特殊訂貨），吸油霧機(jī)等配置。

II. MACHINE FEATURRES

1. The machine consists of the following major components: the machine bed, the cradle, the grinding wheel bracket, the workhead, the main drive, the sliding base feed mechanism and the hydraulic drive ystem. The grinding wheel is fastened on the spindle of the grinding wheel bracket. The grinding wheel position to the workpiece can be adjusted in a certain distance, by moving the grinding wheel bracket. The workpiece is chucked on the arbor which is mounted into the work spindle and fastened by means of a hydraulic chuck. The root angle of the workpiece to be ground can be adjusted by turning the workhead on the sliding base and the workhead setting will be determined by adjusting the horizontal position off the worrkhead. In addition, the sliding base must be moved forward or backward toward the central position under certain circumstances to satisfy the demａnd of the sliding base position.

2. A grinding wheel dresser is equipped on the machine, which has two diamond styluses (One is used for the tooth profile and the other is used for dressing the circumference of the grinding wheel.)

3. Crowned teeth and profile corrected teeth can be ground on this machine by the modifying device of the mechanical mechanism. With the exception of workpiece loading and unloading, all the machine operations are performed automatically in an automatic work cycle.

4. A SIEMENS 828D CNC control system is equipped for the machine, which has 5 drive axes and perform 3-axis simultaneous movements of the cradle indexing, the workhead indexing and the lead screw of the sliding base. Automatic machine setting ups can be made by means of the user-friendly grinding software package, which is of easy operation and convenient use.

5. The machine is designed for grinding one flank of the tooth and the other flank of the tooth can also  be ground rotating the cradle. Therefore, this is a rigid machine with faster grinding cycles. Modern grinding specifications can be adopted on this machine and paper filter, thermostatic oil tank (on special order), oil-mist exhauster, etc. will be available.
