Let's take a closer look at the technical specifications of the stack door. The stacked door, also known as the quick-stack or high-speed stack door, is ideal for high-frequency logistics applications. Its segmented curtain design consists of aluminum wind-resistant rods, offering both strength and aesthetic appeal. The fabric curtain and window material can be easily replaced, allowing for quick maintenance and improved operational efficiency. Additionally, it provides excellent insect-proof and dust-proof performance, significantly enhancing the overall environmental quality.
**Technical Parameters:**
- **Appearance:** The door frame is made from high-strength anti-oxidation aluminum alloy (120×130mm), available in silver white, meeting the 6063-T6 standard. Alternatively, a cold-rolled steel plate with electrostatic spray coating is used for the frame (140×150mm) and door cover.
- **Power Performance:** Equipped with a German SEW brake motor, power range from 0.75 to 1.5KW, with a voltage supply of 220V/380V and a brake voltage of 220V.
- **Control System:** Features an imported microcomputer variable frequency control box with a Mitsubishi CPU for precise operation.
- **Control Voltage:** Operates on a safe low voltage of 24VDC.
- **Opening Speed:** Can open at 0.8–1.5m/s and close at 0.6–1.2m/s, with adjustable speed settings for different needs.
- **Curtain Material:** Made from imported high-density polyester fiber with surface coating treatment, thickness ranging from 0.8mm to 1.5mm, and available in multiple color options.
- **Tensile Strength:** Up to 5700/5100N/5cm, with tear resistance of 900/80N.
- **Fire Rating:** Meets the German standard MZD/NBL, classified as difficult to burn.
- **Operating Temperature:** Functions effectively between -10°C and +70°C, with special versions suitable for extreme cold down to -40°C.
- **Transparent Window:** Made from imported PVC transparent crystal soft board, 1.5mm thick, available in rectangular or oval shapes.
- **Wind-Resistant Material:** Aluminum alloy wind-resistant ribs, designed in a segmented structure for easy replacement.
- **Wind Resistance:** Capable of withstanding winds up to 9m/s under a 50Pa standard (3×3m).
- **Sealing Performance:** A U-shaped airbag cloth pocket at the bottom ensures tight contact with uneven floors, while double-side sealing at the top prevents dust and insects from entering.
- **Safety Features:** Includes standard infrared photoelectric protection, pressure airbag, warning lights, anti-collision columns, and a manual crank for power failure situations.

(1) Diamond pen dressing grinding wheel: According to the size of diamond particles and their distribution in the pen, diamond pens can be divided into several types, such as chain and powder. The alloy with strong bonding force is used as the bonding agent, so the diamond grinding wheel particles are not easy to fall off during use, so there is no need to repair the grinding process.
(2) Grinding wheel dressing by rolling method: Diamond grinding wheel dressing by rolling method. Grinding wheel drives the rolling wheel at the speed of 1~2m/s by reducing the speed
Made of, carbide or abrasive) rotary. The pressure of rolling wheel applied to grinding wheel is about 3~5MPa, grinding the surface of diamond grinding wheel
Make the abrasive particles fall off. The grinding wheel dressing by rolling method has better cutting performance and lower cost, but the surface roughness of the grinding part is rougher and rolling
Damage, short life, easy loss of precision. Therefore, this dressing method is mainly used for forming grinding with small batch size and low precision.
Green silicon carbide or ceramic white corundum is used for dressing. Dressing ring is the first choice for dressing diamond grinding wheel or CBN grinding wheel. It is sharp in dressing, not easy to remove sand and has high dressing efficiency.
