Against the backdrop of accelerated precision and automation in global high-end manufacturing, sheet metal fabrication and CNC machining—as two cornerstone technologies for metal component production—continue to drive innovation across automotive, electronics, aerospace, and energy industries. Though often mentioned together, they exhibit fundamental differences in process principles, application scenarios, and technical approaches. This article systematically outlines their distinctions and provides an in-depth overview of current mainstream metal processing service types.   一、Process Essence: Forming vs. Cutting Sheet metal fabrication uses thin metal sheets (typically 0.5–6mm thick) as raw material. It achieves part shaping through non-cutting methods such as shearing, punching, bending, and welding, with its core principle being “forming.” Its advantages include high efficiency, low cost, and suitability for mass-producing structural components like cabinets, enclosures, and brackets. CNC machining, however, is a subtractive manufacturing process. It employs high-precision machine tools to perform three-dimensional cutting on metal blocks, bars, or thick plates, achieving complex geometries by removing material. Emphasizing “precision” and “complexity,” it is widely used in aerospace, medical devices, precision in

In the field of metal processing and manufacturing, copper alloys have long held a significant position due to their excellent electrical conductivity, corrosion resistance, and machinability. Among these, brass and bronze are the two most frequently mentioned materials. Many assume they are simply “one yellow, one blue,” but in actual engineering applications, their compositions, mechanical properties, processing difficulties, and even costs differ greatly. Choosing the wrong material can result in increased tool wear and reduced production efficiency at best, and at worst, lead to premature part failure or even safety incidents.   一、Different Chemical Compositions The core distinction between brass and bronze lies in their base alloy elements, which determine their fundamental performance differences. For example: Brass is copper-based with zinc as the primary additive, offering superior ductility and plasticity for easier machining and forming;

In sectors with urgent lightweighting demands—such as aerospace and new energy vehicles—aluminum alloys have become critical materials. However, their high-precision CNC milling processes present significant challenges, often leading to reduced yield rates and uncontrolled costs. Industry experts note this is a systemic engineering endeavor involving materials, processes, and equipment. The core challenges and cutting-edge countermeasures are outlined below: 1. Thermal Deformation Challenge Manifestation: Significant localized temperature rise during high-speed cutting causes warping in thin-walled, large-surface workpieces. Strategy: Implement minimum quantity lubrication (MQL) or low-temperature cooling; optimize tool paths by adopting layered symmetrical machining; incorporate thermal compensation algorithms.   2. Residual Stress Release Challenge Manifestation: Internal stresses redistribute after rough machining, causing springback deformation upon clamping removal. Strategy: Implement a “rough machining → stress aging → finish machining” process sequence; apply vibration stress aging technology; utilize finite element simulation to predict and optimize machining order.   3. Tool Clogging and Build-Up Edge Challenge Manifestation: Aluminum chips readily adhere to tools, causing surface roughness and dimensional fluctuations. Strategy: Select low-friction tools like diamond-coated inserts; employ high-speed, high-feed shear-type cutting; strictly monitor tool life.   4. Insufficient Rigidi

一、Four Primary Causes of Post-CNC Deformation in Plastic Parts Compared to metals, plastics exhibit more sensitive physical properties and reactions during machining, making them more prone to deformation. Technical experts identify the following four key factors: Plastic Thermal Expansion Coefficient Far Exceeds Metal Plastic typically exhibits a thermal expansion coefficient 3–8 times higher than metal. During CNC milling, friction between the tool and material generates significant heat, causing localized temperatures to rapidly rise to 60–80°C. If heat cannot dissipate promptly, it leads to irregular plastic expansion. Uneven cooling and contraction after machining then cause warping or bending deformation. Insufficient Release of Internal Plastic Stress During injection molding, uneven cooling of plastic blanks can leave residual “internal stress” within molecular chains. Without proper pre-treatment before machining, CNC milling removes surface material, causing rapid stress release and resulting in “s
