There are peaks and valleys with small spacing on the surface of the part, and the micro-geometric characteristics formed by it are called surface roughness. When CNC machining parts, it is formed due to the tool marks left by the tool on the surface of the part and the plastic deformation of the surface metal when CNC cutting and splitting.
تعد معايرة أدوات أدوات آلة CNC مهارة مهمة في التصنيع. تحدد دقة إعداد الأداة دقة تصنيع الجزء, وتؤثر كفاءة أداة المعايرة بشكل مباشر على كفاءة تصنيع الجزء. يعد إعداد الأداة مهمًا جدًا لعمليات معالجة الأدوات الآلية.
The reaming method is shown in Figure 7-4, and the reaming allowance (D-d) can be consulted in the table. The form of the reamer varies with the diameter. The diameter of Φ10~Φ32 is a taper shank reamer, as shown in Figure 7-5a. The diameter of Φ25~Φ80 is a sleeve type reaming drill, as shown in Figure 7-5b.
Single-edge boring tool boring has the following characteristics:
(1) The adaptability of boring is strong. Boring can be carried out on the basis of drilling, casting and forging holes. A wide range of achievable dimensional tolerance levels and surface roughness values;
Reaming is a finishing method for holes on the basis of semi-finishing (reaming or semi-finishing boring). The size tolerance of the reaming hole can reach IT9~IT6, and the surface roughness value can reach Ra3.2~0.2μm.
من أجل تلبية احتياجات الآلات المختلفة للعملاء, توفر شركة Methods Machine Tool نموذجين من آلات Nakamura Tome المجهزة بالمحور B. تم تصميم الأداة الآلية STW-40 مع مبدل الأدوات الأوتوماتيكي القياسي ذو 40 محطة لمعالجة الأجزاء الكبيرة والثقيلة. مثل: المسبوكات والمطروقات, ويمكن معالجة قطع العمل حتى 17 بوصة في القطر. لكن, in response to customer needs, Methods Machine Tool Company can now provide a smaller model of B-axis machine tools, namely NTJ (B-axis turret).
Mechanical surface treatment of parts
It mainly includes wire brush roller polishing method and shot peening method. The polishing method is that the brush roller is driven by the motor, and the brush roller rotates at a high speed on the upper and lower surfaces of the strip in the direction opposite to the movement of the rolling piece to remove the oxide scale. The brushed iron oxide scale is washed away with a closed circulating cooling water washing system.
What is the cost of CNC machining? man-hour Quote for CNC machining of different materials (معدن, بلاستيك).
أولاً, CNC machining costs will vary significantly due to the different CNC machining parts you are doing. Before placing an order, it is necessary to check the overall budget of your project. You must consider several aspects that affect the cost of CNC machining.
CNC machining parts refers to a process method that uses information and digital devices to control the movement of parts and cutters to process parts on a CNC machine. It is an effective way to solve variable rapid prototyping components, small batch parts, complex shaped parts and high precision CNC machining components and achieve high efficiency parts.
