YK2632 CNC Straight Bevel Gear Grinder

YK2632 CNC STRAIGHT BEVEL GEAR GRINDER

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.

 

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.
