Optimization Methods for Surface Roughness in Precision Machining
In fields such as precision mechanical machining, CNC (Computer Numerical Control) precision machining, and medical component machining, surface roughness is one of the key indicators for measuring product quality. A smooth surface not only enhances the aesthetic appearance of the product but, more importantly, improves its performance and service life. So, how can surface roughness be effectively optimized in precision machining? Rational Selection of Cutting Parameters Cutting parameters have a direct impact on surface roughness.Cutting speed is the primary consideration. In CNC machining, appropriately increasing the cutting speed can reduce fluctuations in cutting force, thereby lowering surface roughness. For example, when machining aluminum alloy parts, a higher cutting […]
CNC Machining of Pipe Threads: An Efficient Technical Solution in the Field of Precision Connection
Pipe threads are the core structure for connecting pipeline systems, and their machining quality directly determines the tightness, pressure-bearing capacity, and service life of pipelines. Against the backdrop of the manufacturing industry’s transformation toward precision and efficiency, CNC machining of pipe threads, with its standardized and automated technical characteristics, has gradually become the mainstream choice for pipe thread production across various industries. This article will objectively analyze the core value of CNC pipe thread machining from three dimensions: technical definition, application scenarios, and process advantages. CNC machining of pipe threads refers to a technical method that uses a Computer Numerical Control (CNC) system combined with specialized CNC machining equipment […]
Robot Experience Stores Blossom Everywhere: A Commercial Revolution Moving from Labs to a New Ecosystem
Not long ago, the scenario of an embodied intelligent robot—capable of walking, operating tools, and communicating—integrating into daily life was exclusive to science fiction works. Today, as robot experience stores open “like bamboo shoots after rain” across the country, this scene seems to be accelerating its transition from the screen to reality. Global’s First Robot 4S Store Opens On August 8, 2025, the world’s first robot 4S store officially opened. The biggest difference from an automotive 4S store is that this is not a display space for a single brand, but an aggregation area for robots. By creating an integrated model of “scenario experience—on-the-spot sales—service delivery”, it paints […]
Jiefa Technology’s Self-Developed Chip Achieves Mass Production Application in OBC Scenarios for the First Time
Joint R&D Breakthrough AC7840 MCU Enters OBC Mass ProductionRecently, GAC Group’s first new energy vehicle equipped with a fully independently designed chip – the Haobo GT-Climbing Edition – officially rolled off the production line in Guangzhou. The On-Board Charger (OBC) platform installed in this vehicle was jointly developed by three parties: GAC, Zhejiang Fute, and Jiefa Technology (a subsidiary of NavInfo). Among them, Jiefa Technology’s self-developed automotive-grade MCU (AC7840) has achieved mass production application in OBC scenarios for the first time, marking a major breakthrough for domestic chips in the core “three-electric systems” (electric motor, battery, and electronic control) of automobiles. Core Specifications & Dual-Safety Advantages of AC7840According […]
Inspection and Testing Promote Industrial Upgrading! 12 Key Projects Pass Acceptance
Recently, the State Administration for Market Regulation organized the acceptance of the second batch of 12 key projects under the Initiative for Inspection and Testing to Promote Industrial Optimization and Upgrading, and all projects have met the predetermined goals and requirements. These 12 projects focus on the “dual tracks” of tackling key problems in strategic emerging industries and improving the quality of traditional industries. They have made targeted efforts in emerging fields such as integrated circuits, high-end equipment, low-altitude economy, energy conservation and environmental protection, as well as traditional people’s livelihood fields including agricultural products and rail transit. By breaking through a number of key inspection and testing technology […]
