Equipment inspection

The two gear shift levers on the gearbox should be interlocked, and only when one lever is in the center position can the other lever be moved.

The hydraulic buffering mechanism should be able to provide buffering for the reset of the tool holder.

The worktable should ensure smooth movement of the blade, and the assembly and adjustment of the blade mechanism should be coordinated with the reciprocating motion of the gear hobbing machine plug.

The assembly and adjustment of the automatic radial feed mechanism should be correct. 

When the gear hobbing tool is inserted into the processed gear to the required depth, the radial feed should automatically disengage, and the counting device of the machine tool should automatically start

After the workpiece rotates once, the stopper collides with the endpoint switch, causing the machine tool to stop working.

The triangular tape protective cover and hanging wheel cover should be complete and intact, and there should be no automatic opening phenomenon.

The protective cover set on the bed should be intact.

Special tools for cleaning chips should be available

The work site should be equipped with chip and coolant protection devices.

2. Behavior check

Conduct a comprehensive inspection of the protective devices for the mechanical and electrical control handles of the equipment, 

as well as the commonly used tools and measuring instruments on duty, to ensure that they are in good condition, and lubricate them according to regulations.

When fixing the gear hobbing cutter to the spindle, it must be securely fastened to prevent loosening.

The processing of gear blanks must be securely fastened and stabilized, while corresponding pads should be placed at the bottom to ensure that the cutting tool has a certain amount of clearance

When processing several blank parts at the same time, it is necessary to ensure good contact between each end face and no debris in the middle.

T-slot screws must comply with standards, otherwise they cannot be used.

During the operation of the equipment, it is prohibited to change the speed, and attention should be paid to changing the two positions of the handle. 

When one handle is in the working position, the other handle must be in the middle position, otherwise it cannot be started.

When processing cast iron, the cooling pump switch should be turned off.

The operator is not allowed to adjust the clearance of the gear hobbing cutter on their own. When making quick adjustments, the gear hanging wheel must be disengaged.

Adjust the working stroke length of the gear cutter reasonably according to the tooth width, and be careful not to hit the chuck with the gear cutter.

After adjusting the itinerary, manually travel several times to confirm safety before starting work.
