What is the cause of cutting wear on precision nc lathe tools

With the development of modern science and technology, the development of CNC machine tools and greatly promote the progress of cutting technology.With the continuous improvement of production technology requirements, as well as the trend of automation is approaching, the material of the tool began to change, by titanium alloy, carbon fiber composite material, super heat resistant alloy and other new materials made of the tool constantly appear, so that the quality of the tool is constantly improved, the reliability of the tool, precision;Life expectancy and other key factors have also been greatly developed and improved.Wenzhou CNC lathe equipment manufacturers, especially like a high speed vertical machining center, the requirements of the cutter is more stringent.

The wear pattern of the tool in mechanical processing, the tool will be lost after the use of time, the specific manifestations of wear mainly include the following three forms:

Consumption occurring under mechanical action, such as abrasive wear or blade breakage;

Adhesion and diffusion caused by high heat generated during cutting;

The cutting edge eroded by the chemical material is softened and melted.

The cause of mechanical wear is in the cutting of difficult to machining materials, because the tool is easy to wear, almost all the difficult to machining materials have the characteristics of low thermal conductivity, affecting the cutting tool material binder in the high temperature state of binder strength.These three loss patterns can be analyzed one by one.Accelerated tool wear.

Due to the high temperature of the tool caused by wear in high toughness, high hardness material cutting, cutting edge temperature generally increased, this will lead to tool wear.In particular, when cutting short pieces of scrap workpiece, high-end CNC lathe equipment manufacturers cutting edge near the crescent wear, the tool in a very short time wear.

Chemical raw materials of the wear for the cutting tool, the composition of the material of some special and specific situation and produce wonderful chemical reaction process material composition, tool coating fall off, even as other chemicals, the generation of this kind of phenomenon will accelerate, customized CNC lathe tool caving blade wear equipment manufacturer, and so on and so forth.
