1, the material must go to the formal place to buy, avoid greed, cheap, quality is more secure. (The main material rejects 10% or 80%. 2. The panel determines the appearance of the furniture. Therefore, the principle of purchasing is the same as above. The appearance panel with 30% of the panel number should be more expensive. The use of blood is necessary.
3. There is also a white panel used for the inner surface of the furniture. The price is relatively cheap and the quality is not too high. The cost is about 30 to 50 yuan per sheet. The procurement principle is the same as above. The interior surface of the furniture is required to be affixed as far as possible.
4, a small amount of 5 PCT board is used for ceilings and algae wells, lighter weight, relatively cheaper prices, but also to choose a good material, the poor easily deformed by moisture. The principle of procurement is the same as above.
5, wood binder contains harmful substances formaldehyde, you can buy smear installed formaldehyde scavenger, construction workers require a day in advance at the incision in the wood, the effect is ideal. If the wood is still odor after the decoration is completed, you can purchase the formaldehyde scavenger used in the spray. Pineapple and tea can also absorb odors, but they cannot decompose or neutralize the toxicity of formaldehyde.
6, furniture made with 12 PCT board is the foundation, the structure is reasonable and durable. The door panels and the exterior-facing panels determine whether the furniture looks good. Therefore, the selection of materials is very important. It is better to buy them together with the woodworking masters. You choose the location and talk about the prices. He picks the goods. The same applies to paint. At noon, remember that the master woodworker eats fast food. This ritual is still necessary.
7, the various lines inside the wood is also inexhaustible price, door line, wood line width, thickness and material determines the price, in principle, the more expensive as possible. Because these things are used on the surface, stingy can not.
8, in general, the rough room needs to install the door and door frame. You can buy it here and you can talk about it by yourself. It's cheaper to do it yourself, because the woodworker wants to make this money. Most of the contractors will separate prices from the doors and frames to maximize their profits. This trick must be seen. The general 1000/door is almost the same, with the door framed. Good luck is words and loose-leaf pages, door touches and door locks. However, these three hardware are best bought by themselves and the quality is more assured. It is also possible for both parties to negotiate the price range and deduct 1,000 yuan from the purchase.
9. The hinged leaflet is installed at the woodworking stage. It is related to whether the opening and closing of the door is smooth or not. It is not possible to save about 30 yuan. One pair can be installed on one door. The door is installed in an inconspicuous place. It can also be installed on the top of the door if necessary. The difference between expensive and cheap is not much, but the hand feels a lot different, or buy expensive. The door lock determines the grade of the door, and it is the most important (not necessarily high-grade), and it is recommended that it be reloaded at the end and it is easy to damage it. The style of the door lock can be based on personal preference, and the average shopping mall is cheaper than the professional market price.
10. Before the panel is affixed to the furniture, it is necessary to use a varnish brush once, be regarded as letting the paint moisten the film attached on the panel (a few millimeters thick), after the preliminary treated panel is attached to the 12 PCT board, Repeatedly brushed paint many times. Brush painting is delicate, the direction of the brush has to pay attention to the speed; the construction of the environment is also required, the air can not have too many sundries; brushed paint in principle should be in situ dry, should not move; drying process paint The flow and tension also affect the final appearance. The best solution is to use air jets instead of brushes, but the amount of paint will double since then. Because labor will also double, workers will generally tell you how bad air spray is.
11. Picking a variety of cabinet door handles is also a very important task. The quality of the furniture is determined by the quality of the handles. It is a crowning touch. Low-grade handles will ruin the style of the entire furniture. The appropriate handles will enhance the furniture. The overall quality, so we must not check. Before picking the handles, you should solicit the opinions of the carpenters to understand the approximate style, size and exact number of handles. The principle of selection is not the price and appearance of the handle, but whether it matches the furniture style. The budget here is 500 to 1000 is normal.
12. After the carpentry is done, keep a small amount of paint. Subsequent construction will surely damage some paint and it will be repaired with these remaining materials. "Don't be good, don't do it."
Single-Row Deep Groove Ball Bearings
Pressed Steel Cages
Single-row deep groove ball bearings are the most common type of rolling bearings. Their use is very widespread.
In addition to open type bearings, these bearings often have steel shields or rubber seals installed on one or both sides and are prelubricated with grease. Also, snap rings are sometimes used on the periphery. As to cages, pressed steel ones are the most common.
For big deep groove ball bearings, machined brass cages are used.
Machined cages are also used for high speed applications.
Extra Small Ball Bearings and Miniature Ball Bearings
Miniature and instrument ball bearings can be divided into two basic types, deep groove and angular contact. The first (deep groove) can be further divided into the following five classes depending on their design details:
Standard type
Flanged outer ring
Extended inner ring
Expanded type in which one ring has a radial thickness that is larger than normal compared with the bearing width.
Thin section type in which both rings are extra thin in the radial direction. They can also be classified as: open, shielded, or sealed.
Maximum-Type Ball Bearings
Maximum-Type ball Bearings contain a larger number of balls than normal deep groove ball bearings because of filling slots in the inner and outer rings. Because of their filling slots, they are not suitable for applications with high axial loads. types of bearings have boundary dimensions equal to those of single-row deep groove ball bearings of Series 6200 and 6300 respectively. Besides the open type, ZZ type shielded bearings are also available. When using these bearings, it is important for the filling slot in the outer ring to be outside of the loaded zone as much as possible. Their cages are pressed steel.
