The basic requirements of CNC precision hardware parts processing mainly include the following aspects:

1. Dimensional accuracy: CNC machining can achieve high dimensional accuracy, typically meeting tolerance requirements of ± 0.01mm or smaller. This means that the dimensions of the processed parts should be very close to those on the design drawings to meet the precision requirements of precision hardware parts.

2. Surface roughness: CNC machining should be able to control the surface roughness of the parts to meet specific requirements. Usually, the surface roughness can reach Ra 0.8 μ M or smaller, sometimes even reaching Ra 0.4 μ Below m to ensure the smoothness and quality of the part surface.

3. Parallelism and perpendicularity: CNC machining needs to ensure the parallelism and perpendicularity of the parts, and ensure that the relationships between the various surfaces of the parts meet the requirements. This usually requires achieving parallelism and verticality requirements within 0.02mm to ensure the geometric accuracy and assembly performance of the parts.

In addition, there are some other technical requirements:

1. Proficient in various operations of CNC machine tools, including startup, shutdown, manual operation, program editing, error handling, etc., and understand the basic principles and operating procedures of CNC machining.

2. Master basic mathematical knowledge such as trigonometric functions, vector operations, coordinate systems, etc., in order to perform related mathematical calculations and image drawing.

3. Familiar with CAD/CAM software technology, able to proficiently master the usage of CAD/CAM software, create corresponding machining programs according to customer requirements or design drawings, and achieve automatic programming and optimization of machining paths.

4. Understand the knowledge of materials and cutting parameters, be familiar with the mechanical properties, machining difficulty, cutting force analysis of various materials, and be able to choose cutting parameters reasonably, such as cutting speed, feed rate, cutting depth, etc., to ensure machining efficiency and quality.

At the same time, CNC precision hardware parts processing also requires precise design drawings, high-quality raw materials, and a reasonable cost budget. Accurate design drawings are the foundation of processing, high-quality raw materials are the prerequisite for ensuring product quality, and reasonable cost budgeting helps to control production costs.

Overall, the basic requirements for CNC precision hardware parts processing cover multiple aspects such as precision, surface quality, geometric relationships, technical operations, and cost control. Meeting these requirements is crucial to ensuring product quality and production efficiency.
