كيفية تحقيق Microlder CNC Machining؟

1. FOUSTER FOURNAY من أدوات الجهاز عالي الدقة

• هياكل صلبة متعددة المحاور: تجمع أدوات الآلة الخمسة المحاور (مثل النموذج الألماني المتطور الذي توفره JS) بين الأدلة الخطية والمحامل الخزفية لتقليل الاحتكاك ؛ تتكون الأسرة من مركبات الجرانيت أو البوليمر لقمع الاهتزاز وضمان الاستقرار الحراري على المدى الطويل (± 0.002 درجة مئوية/ساعة).
• Ultra-hard tool and coating technology
  • Tool material selection: Single crystal diamond (PCD), cubic boron nitride (CBN) or ceramic tool preference, hardness in HV8000 or above, suitable for hard materials such as hard alloy, ceramics.
  • Nanocoating process: Diamond coating or titanium nitride coating is formed on tool surface by physical vapor deposition or chemical vapor deposition to reduce friction coefficient and extend service life 5-10 times.

  3.Environmental control and process stability

  • Thermostatic constant humidity workshop: Temperature controlled at 20±0.5°C, humidity maintained at 40%-60% to reduce the impact of thermal expansion and shrinkage of materials on accuracy.
  • Air purification system: use of HEPA filter (filtration efficiency 0.3 μm >99.97%) to avoid dust pollution on workpiece surfaces.

  4.Optimizing Digital Process Parameters

  • Cutting parameters match: Micro-cutting strategies, such as machining silicon wafers with diamond cutters with feed speed less than 0.01mm/r and cutting depth less than 1 μm, avoid tool chipping.
  • Adaptive control system: Real-time monitoring of cutting force, vibration and temperature, dynamic adjustment of spindle speed and feed speed through PID algorithm to ensure processing stability.

  5.Special materials and surface treatment processes

  • Ultraprecision grinding and polishing: The surface surface roughness Ra <0.01 μm mirror level) was achieved by chemical mechanical polishing (CMP) or elastic emission processing (EEM).
  • Special material adaptation: For superhard materials such as sapphire and silicon carbide, EDM is combined with CNC grinding.

  

  How does JS company solve the problems of tool wear and thermal deformation when processing difficult to cut materials such as titanium alloys?

  Titanium alloy is known as the king of hard cutting materials because of its high hardness, toughness and poor thermal conductivity. Through the following innovative technologies, JS company systematically solves the problem of tool wear and thermal deformation,and achieved high efficiency and precision cnc machining:

  1.Stiffness enhancement and thermal deformation control of machine tools

  • High rigidity bed frame design: The combination of marble base and polymer concrete structure improves the stiffness of the machine tool by 300% and effectively suppresses vibration induced by cutting force (e.g. amplitude < 0.01mm during titanium alloy milling).
  • Intelligent thermal compensation system: Real-time monitoring of temperature change of spindle and guide rail of machine tool spindle, dynamic compensation of thermal displacement errors by closed-loop control algorithm, guarantee titanium alloy lathe machining and milling accuracy ±0.005 mm.

  2.Professional Tools and Cutting process optimization

  • Superhard tool material: CBN (cubic boron nitride) coated tools and PCD (polycrystalline diamond) tools were developed independently according to the characteristics of titanium alloy, with hardness at HV8000 or above, high temperature resistance increased by 50%, and tool service life increased by 3-5 times.
  • High-pressure cooling technology: In milling and lathe machining, 20MPa high-pressure coolant is injected directly into the cutting area of the tool, which can take away more than 80% of the cutting heat and avoid the phenomenon of high-temperature bonding (chip accumulation) of titanium alloy.

  3. Grinding machining special solution

  • Slow feed strong grinding: Titanium alloy precision parts (such as aviation fasteners) use ultra-hard grinding wheels (such as ceramics combined with CBN grinding wheels) and low speed high feed strategies, with a single grinding depth up to 0.2mm and a 40% efficiency increase.
  • Electrolytic on-line finishing (ELID) technology: In grinding process,the grinding wheel is dynamically trimmed by electrolytic action to maintain sharpness of the grinding wheel, so that the surface roughness the grinding wheel is controlled to be less than 0.4 μm.

  4.JS company's technical verification and case studies

  • Aircraft titanium alloy blade processing: Combining high pressure cooling with CBN cutters, the single-knife cutting length is more than 500 meters and the surface integrity reaches Ra<0.8 μm, satisfying the stringent requirements of aviation engines.
  • Mass production of Medical titanium alloy implants: Micro lubrication (MQL) technology is used instead of traditional cutting fluids, reducing processing costs by 60% while avoiding the risk of material hydrogen embrittlement of the material.
