How to check if the planer is safe?

The planer is one of the commonly used equipment in woodworking, and its safety performance is directly related to the life safety and production efficiency of the operator. In order to ensure the safe use of the planer, regular safety inspections are essential. Here are some key steps and points for checking whether the planer is safe:

1. Equipment inspection

1.1 Planer shaft inspection

Ensure that the planer shaft adopts a cylindrical design, and triangular or square planer shafts are prohibited

The radial runout of the planer shaft should be less than or equal to 0.03mm, and there should be no obvious vibration during operation

The surface of the knife groove on the planer shaft where the planer is installed should be flat and smooth without cracks

1.2 Press screw inspection
The press screw must be complete and intact. If damaged, it should be replaced in time, and it is strictly forbidden to continue to use it

1.3 Guide plate and adjustment mechanism inspection
The guide plate and guide plate adjustment mechanism should be intact, reliable, flexible and easy to use

1.4 Electrical safety inspection
Check whether there is short circuit protection and overload protection, and whether it is sensitive and reliable. The fuse meets the requirements and shall not be replaced arbitrarily
The machine tool shall be grounded (zero) and have a time-display mark

1.5 Transmission system inspection
The transmission system shall have a protective cover and shall not be removed when working

1.6 Dust collection device inspection
The dust collection device shall be effective to reduce the impact of dust on the working environment and operators

2. Behavior inspection
2.1 Safety of planer replacement
The power supply shall be cut off and a “no start” safety sign shall be set for each planer replacement

2.2 Machine tool fault handling
If the machine tool fails or the planer is blunt, the machine shall be stopped immediately and the power supply shall be cut off

2.3 Safety of chip removal channel cleaning
To clean the chip removal channel of the machine tool, the machine shall be stopped first, the power shall be cut off, and the knife shaft shall be completely stopped before proceeding. It is strictly forbidden to pick up wood chips with hands or feet

3. Working environment inspection
3.1 Machine tool installation environment
When the wood planer is installed outdoors, there shall be rain, sun and fire protection facilities
The area around the machine tool shall be spacious to ensure convenient and safe operation and maintenance

3.2 Lighting and material placement
Make full use of natural lighting, or set up artificial lighting
Material placement is neat and the path is unobstructed

By following the above inspection steps, you can effectively ensure the safe use of the planer and prevent accidents. Regular safety inspections are an important measure to maintain the performance of the planer and extend its service life, while also ensuring the safety of the operator.
