There are several installation methods for finger joint milling cutters. What are the characteristics?

The face milling cutter has 2 or 4 cutting edges, and the number of mounting plate milling cutters depends on the width (vertical type) or thickness (horizontal type) of the workpiece. According to the cutting edge position,

a. The edge of the adjacent chip milling cutter coincides (type I);

b. The cutting edges of adjacent chip milling cutters are perpendicular to each other (Type II);

c. The cutting edge of a set of milling cutters is helically staggered (type III);

These three types of tooling have different cutting resistance and command processing accuracy. In the form of the type I tool, since the coincident blades simultaneously participate in the cutting and leave the workpiece at the same time, each set of cutting edges is cut at the same time every time the milling cutter rotates, so the cutting force also changes periodically, the cutting vibration and the cutting noise are large, and the cutting is performed. The resistance is also large, but the command processing accuracy is high. In the type II tooling type, each time the milling cutter rotates, the cutting edge of each set of milling cutters is reduced by half compared with the type I. Therefore, the cutting force of the milling cutter is reduced, and the cutting vibration and cutting noise are also reduced. In the form of type III knives, the cutting edges that participate in milling cut one by one and leave the workpiece one by one. The workpiece has good smoothness, low vibration, high surface finish, and the durability of the tool is higher than that of the two types of knives. From the perspective of cutting resistance, the cutting resistance of type I is the largest, and the vibration and cutting noise generated by the cutter shaft are also the largest when cutting, while the cutting resistance, vibration and noise of type III are the smallest. From the perspective of command processing accuracy, the type I command processing has the highest precision, while the type III has the lowest precision. In actual production, in order to reduce the vibration of the power load, two types of tooling methods, type III or type II, are generally used.

The Outport Stopper For I.V Fluid Bag is based on the polycarbonate joint formed by injection molding process, comprising of the injection‐purpose halogenated butyl rubber stopper and aluminum‐plastic composite cap. Among which, the material for polycarbonate joint is the imported medical‐level polycarbonate, complying with the FDA rules; the aluminum‐plastic composite cap is produced by using the imported top‐quality aluminum strip; the injection‐purpose halogenated butyl rubber stopper can be chosen to use the well‐known domestic product or imported product on the request of user.

The infusion stopper is produced in the clean plant, with the partial part reaching to Class 100 under the Class 10,000 background. The main working procedures, such as the injection molding and the cleaning, riveting, inspection, wash, assembly and etc., are designed and processed as per the cleanliness requirements at the partial level of Class 100, which passes the GMP on‐site certification and complies with the cleanliness requirements of high capacity injection medicine.

The main production equipments, test and inspection instruments of infusion stopper have already reached to the international level and are advanced at home. Meanwhile, the full production process is conducted the strict control and management, and making product free of plasticizing agent, loading agent and lubricating agent, and free of absorption or transfer when contacting with liquid medicine, neither the pyrogen and soluble matter, thence such equipment may ensure the product quality.

The outport stopper for I.V fluid bag is mainly used for double‐hose non‐PVC software bag.
