The hardware of sliding doors (also known as sliding doors and sliding doors) is structurally similar regardless of the brand. However, from the hardware and other accessories, it can reflect the grades and differences. Often the hardware and accessories used in the brand sliding door are more expensive. On the contrary, the cheaper the sliding door is in the hardware. Places that are neglected are used a bit more.

The main structure of the sliding door:

Vertical frame, upper rail, lower rail, upper horizontal frame, lower horizontal frame, sub-bar, upper and lower pulley, core plate, anti-collision bar, positioner

Main material of sliding door material:

Stainless steel, aluminum, other alloys, now in addition to the low-end sliding door brand is still using stainless steel as a frame, almost all use aluminum, or alloy.

Surface treatment:

Paint finish, galvanized (chrome), PVC cladding, natural veneer veneer

Main specifications of sliding door materials:

Up and down rail 6 m / root, up and down horizontal / middle spacer 4.88 m / root, mullion 4.88 / root

Glass: 1830mm*2400mm 1600mm*2400mm

Wave board: length 2440mm width 130mm

Cabinet board: 1220*2440

Sliding door aluminum category

GB aluminum: high-quality aluminum ingots are made by adding certain components of magnesium. Taking high-quality aluminum, which is often used as the sliding door frame, as an example, the aluminum alloy with the aluminum grade of 5019 should have a chemical content of magnesium above 4.5% according to national standards. It has strong hardness, good toughness and is not easy to be oxidized. long lasting.

Non-standard aluminum: Made of waste recycled aluminum, the aluminum alloy has poor toughness, insufficient hardness, easy deformation, cracking and oxidation, and short service life.

Main indicators of the quality of sliding door profiles

1. Profile aluminum: Whether to use the national standard aluminum, directly determine the product quality and cost / many of the current market use non-standard recycled aluminum, the appearance of the ordinary consumer can not be discerned after treatment.

2, wall thickness (cross section): must choose a product with a cross-cut thickness of 1.2MM or more.

The minimum nominal wall thickness of doors and window profiles shall not be less than 1.20 mm, and the minimum measured wall thickness of aluminum alloy profiles for outer and outer windows shall comply with the provisions of GB/T 8478 and GB/T 8479, respectively.

3, surface treatment: whether the paint surface is smooth, whether the PVC sample has foaming and peeling phenomenon.

Sliding door pulley:

The sliding wheel is one of the most important components of the sliding door, which directly determines the service life and sliding effect of the sliding door. The good sliding door brand will not be taken lightly on the sliding wheel. The quality of the sliding wheel mainly depends on the bearing of the sliding pulley. And the quality of the rim material. At present, good sliding door brands will use large bearing wheels and resistance nylon wheels.

CBN Cutting Discs

CBN abrasive is mainly used for steel parts, such as high speed steel, die steel, 45 steel, etc., can be made into electroplating CBN, resin CBN, sintered CBN. Can be made into grinding wheel, cutting pieces, grinding head. Abrasive sharp, high temperature resistance, good thermal stability, wear resistance. The hardness of CBN is higher than that of ordinary abrasives and the ability to maintain shape is one of the main characteristics of high performance abrasives. CBN is very resistant to pressure. CBN has good thermal conductivity and can achieve cold cutting during grinding.

strong wear resistance, long life

The grinding ratio of CBN wheel can reach 3500-5500, which is 100 times higher than that of ordinary corundum wheel and 3-5 times higher than that of diamond wheel.

environmental protection, no pollution, energy saving and consumption reduction

No too much powder dust.

High work efficiency and good comprehensive economic benefits

The grinding is sharp, the grinding force is small, the dressing cycle of CBN wheel is long, the dressing amount is less, and the replacement time is long. Long service cycle, high grinding ratio, can obtain better economy, good shape retention in use, do not need to change and trim grinding wheel often, save working hours, improve working conditions, is conducive to machining operation.

Cubic boron nitride is not suitable for grinding hard metals and non-metallic materials. At high grinding temperature, CBN will react with alkaline aqueous solution. CBN grinding wheel will decompose in alkaline solution at 300℃, and can decompose in trace amount in boiling water, which will destroy the crystal shape of grinding grains. Therefore, oily coolant should be used instead of water-based coolant during grinding.
