Interestingly, Neos started with only 3 people, and only 30 people so far. In just 5-6 years, it has developed into a star in the parallel machine tool industry.
The "Inverted Vehicle" of the V100 three-bar parallel mechanism exhibited by the US branch of Index Germany (that is, the spindle and the workpiece move on the X and Z axes, and the tool does not move, and the tool can be converted back, but no linear motion is performed. The vertical lathe, which is known as the "inverted car" in China, uses a parallel machine tool for the lathe, which is very clever. This is because:
One of the biggest weaknesses of a parallel mechanism is the low effective utilization of space. Therefore, the range of the spindle platform should be small, and the lathe is not like the machining center. The moving range of the workpiece relative to the tool is small, so the V100 is compact.
2 lathes generally only need two degrees of freedom (X and Y axis). The three-bar mechanism can now obtain three degrees of freedom of X, Y, Z, and also one degree of freedom, which can be used for automatic loading and unloading.
In order to increase the rigidity, the index adopts a double-rod structure with two rods acting as a rod, which can also be called a three-double rod structure, which is similar to the structure of the Tianjin No. 1 Machine Tool Plant.
The V100 is fitted with a 5-inch chuck. The electric spindle rotates at 8000r/min, the power is 26.48kW.X, the Y and Z strokes are 450mm, 150mm and 175mm respectively. It can automatically load and unload and sell for 175,000 US dollars. It is said to have sold 5 units in Europe. The V100 may be the world's first parallel mechanism lathe.
Hexel Corporation of the United States has used a six-bar parallel structure as a separate component for turret milling machines. This upgrades low-cost conventional milling machines to 5-axis simultaneous milling machines. The table diameter is 710mm.X, the Y stroke range is 305mm diameter circle, Z axis is 178mm, A axis is ±25μm, the maximum feed rate is 5.1m/min, weighs 91kg, and the price is USD 7900 (including control software). It is said that 200 units will be produced in 2001.
In addition, the aforementioned Z3 composite spindle head may be the first example of a parallel mechanism for small parts of machine tools.

Industrial sectional doors are the most durable and longest lasting doors to ensure circulation at the areas of the factory entrance and exit of goods, loading and unloading areas.
The body of sectional door is forming by 40 mm sandwich panels. These panels provides sound and heat insulation due to the intense doped polyurethane insulation was injected between galvanized steel sheet. (50 kg/m3).
Industrial sectional door systems provide space-saving with opening parallel to the ceiling.Any opening can be used clearly . and produces in accordance with the transition range and the height in the factory buildings or warehouses.
Doors is working sliding by be the most appropriate the gap between the top level of the gate with a ceiling height within the side rasils. The door can be mounted in different ways according to the gap distance (standard, low, highlift and vertical track systems).
Industrial sectional doors can easily be opened automaticly by 230-380 V-AC/50 Hz electric motor or manualy thanks to torsion spring system that balances the weight of the door.The galvanized springs are made to be durable of 25.000 door cycles.Motor with emergency chain All the drive systems have a mechanical back-up system fitted to the reduction gearbox of the electric motor, so that the sectional door can be opened if the power fails. The reduction gearbox can then be powered using the chain.
