1、 Reason for the gear hobbing machine not returning the blade

1. Poor fit between the cutting tool and the workpiece

When using a gear hobbing machine, if the tool does not fit well with the workpiece, it is likely to cause the phenomenon of not retracting the tool. 

Because when the tool and workpiece are not properly matched, the cutting force will increase, causing the gear hobbing machine to be unable to cut and naturally unable to retract the tool.

2. Gear hobbing machine malfunction

When the gear hobbing machine malfunctions, it may also lead to the phenomenon of not returning the tool. 

This type of malfunction may be caused by poor machine structural design or poor wear of machine components. In this case, it is necessary to repair the machine and replace parts.

2、 Non retraction processing method for gear hobbing machine

1. Adjust the tool

When the phenomenon of non retraction occurs, the problem can be alleviated by adjusting the tool. The specific method is to increase the reamer and rake angle, 

which can reduce the cutting force of gear hobbing and prevent the phenomenon of non retraction.

2. Check if the machine is malfunctioning

When the gear hobbing machine fails to retract the blade, it is necessary to check whether the machine is malfunctioning. 

If the failure to return the blade is caused by a machine malfunction, it is necessary to repair the machine and replace damaged components.

3. Adjust process parameters

When using a gear hobbing machine, different process parameters can have an impact on the phenomenon of no tool return. 

Therefore, the phenomenon of no tool return can be alleviated by adjusting the process parameters. Specifically, the cutting depth and cutting speed 

can be appropriately increased to reduce the cutting force of gear hobbing and prevent the phenomenon of tool failure.

4. Enhance maintenance and upkeep

The service life and performance of a gear hobbing machine are closely related to daily maintenance and upkeep.

 Therefore, in order to ensure the smooth operation of the gear hobbing machine, it is necessary to strengthen daily maintenance and upkeep. Including: 

regular cleaning and lubrication of the machine, maintaining smooth operation of the machine, regular inspection of machine wear and replacement of parts, etc.

As an important metal processing machine, the gear hobbing machine needs to be promptly inspected and solved when encountering the problem of not returning the tool during use. 

This article introduces the reasons and solutions for the gear hobbing machine not returning the blade, hoping to be helpful to readers. 

At the same time, in order to ensure the normal use of the machine and extend its lifespan, it is recommended to strengthen the daily maintenance of the machine.
