In the world of precision machining, precision is like a shining pearl, which determines the quality and value of the product. So, what exactly is precision in precision machining?
Precision in precision machining is the ultimate pursuit of the accuracy of the geometric parameters of parts, covering three key dimensions: dimensional accuracy, shape accuracy and position accuracy.
Dimensional accuracy requires that the deviation between the actual size of the part and the designed size be strictly controlled within a very small range. Taking micromachining as an example, when manufacturing tiny electronic components or medical device parts, the dimensional error may be measured in microns or even nanometers. For example, in the chip manufacturing process, the width deviation of the circuit line must be very small, otherwise it will affect the performance and function of the chip. When performing this type of precision machining, Airy Precision Machinery uses high-precision measuring instruments, such as laser interferometers, to monitor and feedback the dimensions during the machining process in real time to ensure that the dimensions of each part can accurately meet the design requirements.
Shape accuracy is about the fit between the shape of the part and the ideal shape. For flat parts, the flatness requirement is extremely high. In the processing of optical lenses, the surface of the lens needs to achieve extremely high flatness to ensure the refraction and focusing accuracy of light when it passes through. Airui Precision Machinery uses advanced grinding and polishing technology, combined with the high-stability motion control of ultra-precision machine tools, to control the surface shape error of the lens within a very small range, so that the lens can present excellent optical performance. For rotating parts, such as shafts, the shape accuracy indicators such as roundness and cylindricity are of utmost importance. Airui Precision Machinery optimizes turning and milling processes, and selects suitable tools and cutting parameters to ensure that the shape accuracy of shaft parts meets the stringent requirements of industries such as high-end equipment manufacturing.
Position accuracy focuses on the accuracy of the relative position between the various features of the parts. In the processing of precision parts in the aerospace field, such as the connection holes between the blades and the hub of an aircraft engine, the position accuracy is directly related to the assembly accuracy and overall performance of the engine. With its advanced multi-axis linkage machining center, Airui Precision Machinery can accurately control the motion trajectory of the tool in space to ensure that the position tolerance between each feature reaches the minimum value. When processing complex molds, the position accuracy between the core and the cavity determines the quality and precision of the molded product. Airy Precision Machinery makes the position accuracy error of the mold close to zero through rigorous programming and processing process control, thereby producing high-precision molded products.
It is not easy to achieve high precision in precision machining, which depends on many factors. The first is high-precision machining equipment. Airy Precision Machinery has introduced and independently developed a series of ultra-precision machine tools. These machine tools have high-rigidity structures, high-precision spindles and feed systems, and advanced CNC systems, which can provide a stable and accurate motion platform for precision machining. Secondly, the selection and use of tools are crucial. Superhard material tools, special coating tools, etc. are widely used, and the sharpness of the cutting edge, wear resistance and other characteristics of the tools are strictly screened and tested. Furthermore, the control of the processing environment is also indispensable. A stable temperature, humidity and cleanliness environment can reduce adverse effects such as thermal deformation and material expansion caused by humidity. Airy Precision Machinery has created excellent environmental conditions for precision machining by building a constant temperature and humidity processing workshop and using air purification equipment.
Airui Precision Machinery has always been at the forefront of the industry in terms of precision machining accuracy control. Its professional technical team constantly explores and innovates machining processes, and continuously improves machining accuracy by optimizing machining parameters, improving tool path planning and other methods. At the same time, the company has established a complete quality management system, from raw material inspection to monitoring of each machining process, to high-precision inspection of finished products, to ensure that every precision part delivered represents the industry's top precision level, providing a solid precision guarantee for the development of high-end manufacturing, and has won an excellent reputation and widespread trust in many fields such as aerospace, medical, and electronics.
In short, precision in precision machining is a combination of profound art and rigorous science. The unremitting exploration and innovation of industry pioneers such as Airui Precision Machinery in this field are driving precision machining to a higher precision peak.
