Dirty board
Refers to some of the floor paint, giving a dirty "gray" feeling, and some even the footprints are clearly visible. To prevent this from happening, it is important to pay attention to the fact that the surface of the board after polishing is kept clean.
Insects
In order to prevent worms, the first choice is to purchase floors that have been produced through a steam kiln jet steaming process. Although the price is relatively expensive, all the eggs in the wood have been killed; the second is to carefully select the keel, and there are wormholes or bark. Do not use it.
Quilting
Some floors were floored for a few days and there was a large gap between the slats. This is mostly related to the high moisture content before the laying of the floor, and it shrinks due to the high temperature or air drying in the room. Note that the moisture content of the floor prior to laying should be between 8% and 13%, and oiling should be done in time after laying.
sound
Because of the poor quality of floor laying, people will make a buzzing noise when walking on the floor. To this end, we must pay attention to the keel and the ground. The nail between the floor and the keel must be firm, and the number and length of the nails should be appropriate. At the same time, it is necessary to prevent the quantity and length from being appropriate. At the same time, to prevent the keel spacing is too large or the moisture content is too high, otherwise drying and shrinkage after laying will also have a certain impact.
Drum
To ensure that the floor does not play drums,
Pay attention to three points:
First, if the living room is in a humid environment, it is advisable to lay a moistureproof floor;
2. Immediately after the completion of the civil engineering project, solid wood flooring cannot be laid;
Third, when laying, the moisture content of the floor can not be less than 6%. This is mainly because the solid wood floor is not caused by the normal drying process, so the plastic can be laid under the floor during installation. In addition, the floor is placed in the room to be laid two days in advance so that the wood can adapt to the temperature of the room and it can also prevent warping.

1.cylindrical milling cutter
Used for processing flat surfaces on horizontal milling machines. Cutter teeth are distributed on the circumference of the milling cutter, and are divided into straight teeth and spiral teeth according to tooth shape. According to the number of teeth and coarse teeth and two kinds of fine teeth. The helical tooth rough tooth milling cutter has fewer teeth, high tooth strength and large chip space, which is suitable for rough machining. Fine-tooth milling cutters are suitable for finishing.
2. face milling cutter
Also known as disc milling cutter, used for vertical milling machine, end milling machine or gantry milling machine processing plane, end face and circumference have cutter teeth, also have coarse teeth and fine teeth. The structure has three kinds: integral type, insert type and transferable type.
3. End milling cutter
Used for processing grooves and step surface, knife teeth in the circumference and end face, can not work along the axial feed. When the end mill has end teeth through the center, axial feed can be provided.
4. Three-side edge milling cutter
Used for processing all kinds of grooves and steps, its two sides and circumference are provided with cutter teeth.
5. Angle milling cutter
For milling grooves at a certain Angle, there are two kinds of single Angle and double Angle milling cutters.
6.Saw Blade milling cutter
Used for machining deep grooves and cutting off workpieces, there are more cutter teeth on the circumference. In order to reduce the friction during milling, there are 15 '~1° auxiliary Angle on both sides of the cutter teeth. In addition, there are keyway milling cutters, dovetail slot milling cutters, T - shaped slot milling cutters and various forms of milling cutters.
