Material Selection and Procurement: We partner with high-quality aluminum alloy material suppliers to ensure excellent mechanical properties and corrosion resistance of the raw materials. Upon material arrival, we conduct rigorous quality inspections, including compositional analysis, hardness testing, etc., to ensure that the material quality meets the requirements for CNC machining. CNC Machining Process Planning: In response to the design requirements for the tattoo pen casing, we develop precise machining routes and tool selection strategies. We carefully consider CNC machining challenges and process flaws, conducting comprehensive process simulations and analyses to ensure optimal surface finishes and precise machining dimensions throughout the CNC machining process. CNC Machining Process Control: We enforce stringent control over the machining process, monitoring and recording every step along the way. Particularly in precision machining processes such as milling, turning, and drilling, we enhance control over process parameters such as machining temperature and cutting speeds to ensure the stability of product quality. Our meticulous attention to detail ensures consistently high-quality results. Quality Inspection and Measurement: Following the completion of CNC machining for parts, we conduct comprehensive dimensional measurements and visual inspections. Equipped with advanced coordinate measuring machines and optical measuring instruments, we accurately inspect the dimensions and appearance of the parts to ensure that product quality meets requirements. Our commitment to precise inspection guarantees the quality of our products.
