First Class high quality CNC Machine tool Manufacturing technology

In the machining process of CNC machine tools processing non-standard equipment parts, problems such as sticky knives, burning knives, and broken knives often occur, resulting in gnawing of titanium alloy parts, resulting in out-of-tolerance or scrapping of titanium alloy parts. In order to solve the problem of such weldments, the characteristics of titanium alloy materials, machining and cutting characteristics, the selection of tool materials, the processing characteristics of milling, and the coolant are analyzed, so as to improve the pass rate of titanium alloy parts and control the product quality of parts. In order to better control the quality of products, we must first control the cutting parameters of non-standard equipment parts, understand and master the processing characteristics of materials.

The air-bearing spindle also has the advantages of good dynamic characteristics, long accuracy life, no vibration, and a rigidity/load that is commensurate with the conditions of use. However, careful work needs to be done in terms of spindle stiffness, heat generation and maintenance. In order to achieve the air bearing spindle with nano-level rotation accuracy, in addition to the shape accuracy of the shaft and shaft sleeve of the air bearing reaching 0.15~0.2μm, and then achieving it through the homogenization of the air film, it is also necessary to maintain the uniformity of the gas flowing out of the air supply hole. The number of air supply holes, distribution accuracy, inclination angle to the shaft, convex and concave bearing, cylindricity, surface roughness, etc., all affect the uniformity of air flow on the bearing surface. The uneven airflow is the direct cause of small vibrations, which affects the rotation accuracy. To improve the condition of the air supply system, the bearing material should be porous material.

The increasingly widespread application of CNC machine tool non-standard equipment parts processing has promoted the development of cutting technology focusing on efficient turning of titanium alloys. For shops that regularly machine titanium parts, especially large and expensive aerospace components, the 50% increase in productivity is worth the investment in dedicated tool chucks and machines fitted with high-pressure cooling. In order to reduce the cutting temperature, reduce the resulting crater wear, and ultimately be able to use higher feed rates and longer tool life; It is a high-pressure coolant with a special form. Not only does this coolant have high pressures, but it also exhibits a very precise laminar jet pattern that creates a "water wedge" between the chip and the rake face of the insert to hold up the chip and minimize its contact with the rake face, thus avoiding crater wear.
