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.

At the heart of the RHM modular reaming system is the Kennametal Short Taper (KST) coupling system.
Similar to the KM system, the KST system can provide conical contact at the same time, making the tool's runout error less than 3μm, achieving high rigidity connection. The reamer handle and the two drive planes in the body provide uniform torque transfer, allowing the tool to use higher cutting speeds and greater feed rates. There are two clamping options to choose from. The radial clamping system is designed for quick change of the reaming head on the machine; the axial clamping system is an economical clamping system thanks to the clamping screw with differential pitch and the included parts Less, so it provides less drive torque. Both clamping systems are easy to operate.
The reaming head consists of two versions: one is a straight groove type for blind hole reaming; the other is a spiral groove type for through hole reaming and can be applied to two different clamping systems. Standard products for both types of reamers are internally cooled. Since the reaming head adopts unequal groove distances, the occurrence of resonance phenomenon can be reduced, and the straightness of the holes and the consistency of the apertures can be improved. The grinding angle is ground and ground to extend tool life and improve the quality of the hole wall surface and hole. The material of the cutter head is made of cemented carbide or cermet. The reaming head is available in diameters from 20 to 42 mm and can be customised in special sizes. The body type includes straight shank type, HSK type and SIF guide joint type, and the length of the cutter body is 3 times and 5 times of the diameter range of each reamer.
Kennametal launches RHM modular reaming system
Kennametal said its newly developed RHM modular reaming system further enhances the flexibility of high-speed reaming. The system features a high-precision, interchangeable reamer that reduces tooling time and downtime.
