Spline hob is a commonly used tool in machining, which is used to process threads, gears and other parts. The grinding method is as follows:

1. Preparation: Check whether the blade of spline hob is sharp enough. If it is damaged or worn, it needs to be replaced.

2. Clamping the cutter: clamp the spline hob on a special fixture to ensure that the cutter is stable and can rotate.

3. Rough grinding of spline hob blade: rough grinding with grindstone or grinder, and machining the blade edge of the blade to make its taper meet the requirements.

4. Grinding the spline wheel type: grinding with a grinder, and the spline hob is matched with the spline wheel. According to the specifications of spline wheel, select the appropriate grinding head for accurate grinding.

5. Tooth profile finishing of spline hob: Fine grinding with special grinding wheel or grinding head to achieve the required spline tooth profile and size.

6. Inspection and dressing: After grinding, check with measuring tools to ensure that the size and tooth profile of spline hob meet the requirements. If necessary, make minor adjustments and trimming.

It should be noted that grinding spline hob requires certain professional knowledge and experience, and the operation is complicated. For individuals without relevant experience and equipment, it is recommended to send spline hobs to professional processing plants or mechanical maintenance centers for grinding. This can ensure the quality and accuracy of grinding.
