YK2632 CNC STRAIGHT BEVEL GEAR GRINDER

一．机床用途和使用范围

本机床用于大量或大批生产条件下磨削直径320毫米以内模数由1.5到8的直齿锥齿轮。磨齿机磨齿后的齿轮精度可稳定达到GB5级以上。该机床具有较高的加工柔性，良好的动力传动特性，稳定的运动精度和安全的操作性能，适用于加工精密机械，高精度减速机，精密仪器和军工高精度部件等中等规格的高精度直齿锥齿轮，能够显著提高加工后的齿轮传动精度及传动平稳性。

I. MACHINE APPLICATIONS

The machine is designed for grinding straight bevel gears of diameter up to 320mm and module of 1.5 – 8mm in mass production. Accuracy of gears ground on this machine can reach stably to Grade 5 of the GB Standard 。With better machining flexibility, excellent power transmission, stable moving accuracy and safe operating performance, it is suitable to grind middle-sized high precision straight bevel gears used for precision machineries, high precision speed reducers ，accurate instruments & military high precision parts. The transmission accuracy and smoothness of gears ground on this machine will be improved tremendously.

二．机床的主要性能和结构特点

   1．本机床由八个主要部件组成：床身，摇台，砂轮架，床鞍；工件箱，主驱动，床鞍进给机构，液压传动系统。砂轮紧固在砂轮架主轴上，移动砂轮架，砂轮在对工件的一定位置上可调整。工件紧固在装入工件箱主轴的芯轴上，借助液压夹紧夹头紧固。在床鞍上回转工件箱可实现被加工零件的根锥角，及调整工件箱水平位置来确定工件的轮位。此外，在某些情况下使床鞍对中心位置向前或向后移动满足床位要求。

   2．机床上装有砂轮修整装置。借助两金刚笔（一支修齿形用，而另一支修砂轮的顶圆）注意所需要的过凹部倒圆半径的值修整砂轮。

   3．机床还可通过机械机构修正装置加工鼓形齿顶及齿根修缘。机床能以数控程序自动周期进行工作，此时，除上，下工件外，全部工序都自动进行。

   4．本机床由五个传动轴组成，并采用德国西门子（SIEMENS）公司的828d数控系统实现（摇台分度，工件箱分度及床鞍丝杠）3联动的运动控制，通过人性化磨削软件包实现机床的自动调整，磨削软件操作简单，使用方便。

   5．机床加工齿的一边，因此加工齿轮的另一面，则可通过旋转摇台实现。因为本机床是刚性强，行程快的机床，在机床上可用现代化的磨削规范，并提供纸带过滤，恒温油箱（特殊订货），吸油雾机等配置。

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.
