1、Answer The CNC machining process is a computer-controlled manufacturing method where pre-programmed software dictates tool movements to shape raw materials (e.g., metal, plastic, wood). It involves steps like design (CAD), programming (CAM), material…
1、Answer No, CNC (Computer Numerical Control) is not limited to metal. It can machine a wide range of materials, including plastics (e.g., ABS, PEEK), woods (hardwoods, composites), foams (polystyrene, urethane), ceramics, graphite, composites (carbon fiber, fiberglass), and…
1、Answer People use CNC (Computer Numerical Control) for high-precision, repeatable, and efficient manufacturing of complex parts. It automates machining processes (e.g., milling, turning, drilling) using computer programs, reducing human error, increasing production…
1、Answer The minimum thickness for machining aluminum typically ranges from 0.5–1 mm (0.02–0.04 in) for most CNC milling/turning operations, but can go lower (e.g., 0.1–0.3 mm) with specialized techniques (e.g., micro-machining, wire EDM) or soft…
1、Answer The cheapest aluminium alloys for machining are 1100 (99% pure aluminium) and 3003 (aluminium-manganese alloy). 1100 has the lowest material cost (~$2–$3/kg) due to minimal alloying elements, while 3003 offers slightly better…
1、Answer The hardest materials for CNC machining are tungsten carbide (hardness up to 90 HRC), titanium alloys (e.g., Ti-6Al-4V with high toughness), and advanced ceramics (e.g., silicon carbide, hardness 2500 HV). They demand…
1、Answer The best aluminum alloy for CNC machining is 6061-T6, valued for its balanced performance: moderate strength (tensile strength ≥310MPa), excellent machinability (low tool wear), and good compatibility with surface treatments…
1、Answer The choice between 3D printing and injection molding should be based on production scale, design complexity, and cost goals: Give priority to 3D printing: If the demand is for…
1、Answer There is no absolute superiority; it depends on requirements: 3D printing is better for: Low-volume production (<500 pieces), complex curved/hollow structures (e.g., aerospace engine blades), and customized personalization…
1、Answer The core reasons for the high cost of injection molding include: High mold costs: Molds need to be made of high – strength steel (such as H13 die steel)…
