Cardan drive shaft has become a standard tool for many types of industries. There are basically two types of cardan drives shaft available for use: Those made from chrome plated stainless steel and those made from cast iron.
The design involves two pairs of teeth on the outer surface of the shaft. One pair on each side of the core are used to provide the cutting edges. These teeth are attached to a cap at the bottom of the shaft and the cap is fixed to the die.
In most cases, the two-piece set-up is considered more favorable than the more traditional three-piece set-up. When two teeth on one side of the shaft are on the same plane as the adjacent teeth on the other side, they are known as interlocked. When the opposite is true, they are considered different.
When the proper precautions are taken, interlocking is not necessary. It is possible to use one side of the shaft without interlocking the second side. The two side designs are best for applications requiring precision and accuracy.
The two-piece set-up of the cardan drives shaft is preferable for industrial and precision industries that require precision. The interlocking results in the same cutting capabilities of the same size and shape of steel. The one piece shafts can also be used with single or dual carbide abrasive systems. Using the standard carbide system provides additional adhesion between the grinding surface and the face of the product.
When the width of the die is increased, the cross-cutting systems have a greater surface area to which the abrasive will adhere. This increases the adhesion and reduces the overall surface area of the material being ground. This increases the speed of the process which causes the cuts to be done faster.
The speed and precision required to produce high performance in the production of products such as jet engine parts, aluminum and steel alloys, welders, and precision metal stampings, are important aspects of working with the shaft. The shafts are made for applications where fast cutting capabilities are necessary, but the level of precision and accuracy is not acceptable.
For high performance applications, where these two characteristics are acceptable, precision and accuracy are required. The higher the feed rate, the less the blades will "wiggle" when working. If the blades are not spinning fast enough during the grinding process, the abrasive will not stay on the surface of the product.
The finer the material being ground, the greater the speeds must be in order to maintain a fine finish. It is also important to use high quality carbide and diamond tools. High quality cutting tools allow for very precise cutting and do not lose their edge over time.
Metals that are ground with the high quality diamond centers require additional use of a die to complete the final step of grinding. These operations eliminate the need for repeated machining operations. With high quality dies, precise straight cuts are possible.
Metals that are ground with high quality dies are desirable because they require an additional step to complete the final step of the process. Precision and accuracy are achieved and the end product is made to exact specifications.
There are some industries that require direct contact with the product to ensure the production of the finished item is accurate. That is the case with the international trade industry. When the product is needed to be "grounded" or finished, it is required to have a die that has interlocking capability and enough detail to meet the requirements of the industries that require it.
