Christmas tree cutter, also known as steam turbine blade milling cutter or cutting edge cutter, because of its appearance like a Christmas tree, it is also commonly known as the "Christmas tree cutter."

Christmas tree cutter is a milling cutter, is the steam turbine root groove processing efficient processing tool.

Blade is the turbine "heart", is the turbine in the most important parts. It directly plays the steam or gas heat into mechanical energy role. The processing quality of the blade directly affects the operation efficiency and reliability of the unit, and the quality and life of the blade are closely related to the processing mode of the blade. Therefore, the processing of the blade of the turbine work quality and production economy have a great impact. There are many kinds of leaves, but all kinds of leaves are mainly composed of two main parts, namely the steam pipe part and the assembly part of the composition.

The part of the fitting surface is also called the leaf root part, which makes the blade safe and reliable, accurately and reasonably fixed on the impeller to ensure the normal operation of the channel part. The structure and accuracy of the fitting part are therefore determined by the nature, size, accuracy requirements and the nature and size of the stress applied to the duct. Due to the role, size, form and work of the various types of blade channel parts, the structure of the assembly part is also very large. Typical leaves and leaves are shown below:

Turbine blade processing mainly includes the processing and assembly of the steam pipe part of the root processing. "Christmas tree cutter", its unrivaled tool edge design, unique cutting angle and super composite coating greatly improve the processing efficiency, while extending the tool life, reducing processing costs, has made world-class turbine blade manufacturing Business benefits.
