Selection of screw tap
The method of cutting internal threads (nuts), although generally using lathes or screws to tap the teeth, is almost always using screws to tap the teeth when the diameter is small and there is a lot of production.
Reasonable selection of cutting tool materials for aluminum piston machining
The quality of tool material performance is a fundamental factor affecting the surface quality, cutting efficiency, and tool life of machining. When cutting, the cutting part of the tool is directly responsible for the cutting work. The cutting performance of cutting tools mostly depends on the materials that make up the cutting part of the tool, the geometric parameters of the cutting part, and the reasonable selection and design of the tool structure. The level of cutting productivity and tool durability, the amount of tool consumption and processing cost, the quality of processing accuracy and surface quality, etc., largely depend on the reasonable selection of tool materials. The correct selection of cutting tool materials is one of the important aspects of designing and selecting cutting tools.
Forecast of global CBN abrasive market demand trend
A report published by Global Industry Analysis in early 2009 predicted that by 2012, the global market demand for cubic boron nitride (CBN) abrasives would reach $194 million, with an average compound annual growth rate (CAGR) of 3.6% between 2008 and 2012. Among them, the Asia Pacific region has the fastest growth in demand for CBN abrasives, with a CAGR of 5.2% during this period. Japan is the main regional market for CBN abrasives, The expected market demand for 2008 is $42.2 million.
