The anodizing process thickens the hard oxide layer of aluminum. At the same time, parts can be dyed iridescent (thus becoming beautiful parts), or become harder and more wear-resistant.
Anodization is an electrochemical process. It’s been a long time. Its first iteration was born in 1923 and was called the Bengough-Stuart process at the time to protect seaplane components from corrosion. Four years later, a competitive process was patented. Since then, it has become the de facto standard for protecting and beautifying aluminum parts (especially machined and smaller sheet metal parts). Using some form of acid as the electrolyte, all the above components send current through the workpiece (anode) to a series of aluminum strips (cathode) nearby. An acid bath, and color all the pigments (if needed) through the dyeing process after anodization.
Spline milling is one of the processes in which grooves are processed into a large amount of raw materials to produce spline teeth. The following steps outline the process of spline milling:
Load the raw material block to be the spline shaft into the indexing fixture of the milling equipment.
According to the width of the required spline, install the side cutter on the shank of the assembly equipment, and insert the spacer and the spacer between them.
The spindle is mounted on the main shaft of the milling machine, and the milling cutter is placed in the center above the material that will become the spline shaft.
The spline is cut into the shaft through a process called “span milling”. The indexing fixture keeps the shaft of the spline stable while the rotary milling cutter cuts grooves along its length. Depending on the depth of the spline, it may be necessary to perform multiple machining along the same groove. Multiple passes also help to ensure the uniformity of the entire spline.
How to cut the spline on the shaft?
Spline milling is one of several processes of spline cutting, which is the process of machining teeth into internal or external splines. Spline cutting can be used to create intermeshed shafts, gears and other mechanical components, and allows power to be transmitted throughout the mechanical system.
There are four main spline cutting techniques:
