5-Axis CNC Milling Precision Custom Components
Product introduction: Manufactured by precision CNC 5-axis linkage, this product is a bottom bracket of the pipeline type, with an extremely complicated shape and extremely high machining difficulties. It is not difficult for a common CNC milling factory with insufficient experience to make a blank of this product, but its extremely complicated shape leads to high machining difficulties. However, with 5-axis CNC milling in combination with its advanced and precision CNC milling center and skillful mechanical operation engineers, Yijin Hardware makes it very easy to perform machining for this precision custom 5-axis CNC milling part with high quality. Pressure casting is mentioned in this article, because it is required for the blank of this part, but this product is manufactured mostly by precision 5-axis CNC milling.
Product specifications: 800mm*200mm*140mm
casting aluminium. Pressure casting refers to a casting method of pouring molten alloy into the pressure chamber, filling in the cavity of a steel mould, and making the molten alloy solidify to form a casting part. Different from other casting methods, pressure casting features high pressure and high speed.
1.The molten metal fills in the cavity under high pressure and solidifies under higher pressure. Common pressure is within 15 – 100 MPa.
2.The molten metal fills in the cavity at a high speed of 10 – 50 m/s or even over 80 m/s (linear speed of import to the cavity from the flow gate – flow gate speed), so it takes a very short time to make the cavity full of molten metal, just about 0.01 – 0.2 s (depending on the casting part size).
Pressure casting is a precision casting method which produces pressure casting parts with very small dimensional tolerances and very high surface accuracy. In most cases, pressure castings parts can be directly assembled for application without further turning. Even threaded parts can be directly manufactured by pressure casting.
Machining Difficulties and Solutions of the Special-Shaped 5-Way Pipe
The biggest difficulty of this product is how to improve production efficiency. For CNC machining, this product dimensions (800*200*140) are very large and require long machining travels. From the perspective of product structure, there are a lot of irregular steps and cylindrical surfaces, as well as several positions inside, so a large amount of machining is required. Simply using ordinary CNC milling can neither do the job well nor guarantee quality. Besides, if only a single device is used, the machining of every part will take 48 hours. Such low efficiency is due to the use of solid sheet material for the blanks. Therefore, Yijin Hardware suggests that the product blank be manufactured by pressure casting and a machining allowance of 2 – 5 mm be reserved for each key dimensional position of the 5-way pipe and then custom CNC 5-axis linkage be performed directly for fine machining on the blank which has been pressure cast.
Purpose or application scope:
The bottom bracket is a pipe joint with five connection holes and mainly used for fluid or gas delivery. Different bottom brackets are made from different materials, depending on the medium. So, what’s the structure of a bottom bracket? What are its purpose and functions determined by its structure?
A metal 5-way pipe has a main pipe and branch pipes that are located on one side of the main pipe and perpendicular to and connected with it. A valve is set up at the corner of intersection between the main pipe outlet direction and each branch pipe outlet direction, with a round valve plate on it. The valve plate uses a structure of mutual sealing with the inner wall of the pipe cavity when the pipe cavity is closed. This simplifies pipeline setting and reduces the number of pipeline parts used, easy to operate and convenient for branch service and phased supply on each branch. Besides functions of a traditional 3-way pipe, the 5-way pipe provides the double position valve function. That is, either the main pipe or a branch pipe can be set to open or closed state, and the flow ratio between main pipe output and branch pipe output can be adjusted at will. All can be achieved by adjusting the angle of the valve plate in the pipe cavity.
