What are the advantages of CNC machining of radiator parts?

For friends who have been in contact with the radiator component industry, they often see or hear "CNC machining", but too much exposure does not necessarily mean that many people understand. In fact, many questions are still about CNC machining. What are the advantages? Let's take a closer look. CNC machining is an index-controlled machine tool machining, which is a method of using digital information to control the machining process. Traditional mechanical processing is done manually by machine tools. During processing, the mechanical cutter is shaken to cut metal, and the accuracy is measured with calipers and other tools. However, traditional artificial intelligence processing is far from being able to meet the needs of production development. Therefore, the emergence of CNC machining provides the possibility for the standardization, precision and efficiency of mechanical product processing. The CNC machining process in the radiator component industry also shines. The

Investment Casting Materials and Manufacturing Process

Mold material The performance of the molding material should not only ensure the convenient production of investment molds with accurate dimensions and high surface finish, good strength and light weight, but also create conditions for the manufacture of mold shells and good castings. Molding materials are generally formulated with waxes, natural resins and plastics (synthetic resins). All mold materials mainly prepared with wax materials are called wax-based mold materials, and their melting point is low, 60~70 ° C; all mold materials mainly prepared with natural resins are called resin-based mold materials, with a slightly higher melting point, about 70 °C. ~120℃. invest-casting.com   Precision Investment Castings China prototype company service include :  High Quality Investment Casting Parts Custom , Lost Wax Investment Casting Sand Casting , Lost Foam Casting , Gravity Casting , Die Casting , Graphite Casting , Casting Moldsmanufacturers .

알루미늄 합금 다이캐스팅의 단점을 해결하는 것이 편리합니다!

알루미늄 합금 다이캐스팅은 현재 현재의 전자제품 , 자동차 , 생활필수품 등 많은 산업과 분야에서 널리 사용되고 있습니다 . 그러나 알루미늄 합금 다이캐스팅에서 자주 발생하는 몇 가지 결함 및 해결 방법은 다음과 같습니다 .   알루미늄 합금 다이캐스팅   1. 불순물   알루미늄 합금 다이 캐스팅의 불순물 문제는 주로 특정 온도에서 알루미늄 , 규소 및 다량의 철 , 망간 , 크롬 및 기타 화합물을 포함하는 결정립과 일부 산화물로 구성됩니다 .   해결책 : 알루미늄 잉곳의 조성을 엄격하게 제어하고 , 제련로의 난로를 정기적으로 청소하고 , 정기적으로 슬래그를 처리하면 문제를 해결할 수 있습니다 .   2. 구강 문제   다공성은 다이캐스팅 부품의 내부 또는 표면에 나타나는 다양한 크기의 구멍을 말하며 , 이는 다이캐스팅 부품의 경도 부족으로 이어져 표면의 외관에 영향을 줍니다 .   Solution: 적절한 정제제를 사용하여 모공을 처리하고 , 공정을 조정하고 , 저속을 적절하게 줄이고 , 이형제가 너무 많이 분사되어 모공 문제가 해결되지 않는지 확인하십시오 .   3. 균열 문제   균열은 알루미늄 합금 다이캐스팅의 매트릭스가 파괴되고 , 외력의 작용에 따라 확장되는 경향이 있는 선형 또는 기타 라인인 기다란 틈이 형성되는 것을 의미합니다 .   솔루션 : 합금 조성을 올바르게 제어하고 , 냉각수 회로를 늘리고 , 알루미늄 합금 다이캐스팅의 구조를 변경하고 , 사출 위치를 변경하거나 증가시키면 해결할 수 있습니다 .

Analysis of Machining, Technologies and Structural Materials for Shaft Parts

1. Analysis of the structure, material and process of shaft parts

(1.)Function and structure of shaft parts

Shafts are used to support transmission parts and transmit torque or movement. The shaft needs to bear the load during work to ensure a certain degree of rotation accuracy. The machining surface of shaft parts usually has inner and outer cylindrical surfaces, inner and outer conical surfaces, step planes and end planes, as well as threads, splines, keyways and grooves.

 

(2. )Materials and blanks of shaft parts

The materials of shaft parts generally include carbon structural steel and alloy structural steel

The blanks of shaft parts include round bars, forgings, and steel castings.

 

(3.) Analysis on the processing technology of shaft parts

①The common axis is the radial design benchmark for each rotating surface. For shafts with high accuracy requirements, the axis of the center holes at both ends can be used as the radial machining datum; for shafts with low accuracy requirements and for rough machining, the outer circular surface can be used as the machining datum

 

②Machining in the order of rough turning→semi-finishing turning→finishing turning, the shafts with high precision requirements should be arranged for grinding.

 

③The spline, keyway, and thread processing on the shaft are arranged after turning and before cutting; for the shaft that needs to be quenched, the thread processing is placed after surface quenching

 

④When the shaft blanks are forgings, normalizing treatment should be arranged, and important shaft parts should undergo multiple heat treatments

 

Typical process of shaft parts

2.Analysis of gear shaft processing technology

(1.)Analysis of parts

 

(2.)Blank selection

 

(3.)Division of processing stages: divided into three stages: roughing, semi-finishing, and finishing

<1>Roughing stage: flush the end face, punch the center hole, and rough the outer circle

<2>Semi-finishing stage: semi-finishing turning, finishing each external circle, threading, keyway milling, gear milling

<3>Finishing stage: study the center hole, rough/finish two outer circles of 20, taper 1:10 truncated cone/30 gear top circle

 

(4.)Benchmark selection: rough turning adopts the outer surface and the center hole as positioning benchmarks, and adopts "one clamp and one top" turning,Two center holes are used as positioning reference when finishing turning and grinding

 

(5.)Heat treatment process: the quenching and tempering process is placed after the rough turning process and before the semi-finishing process; the gear quenching is before the grinding process

 

(6.)The processing process of single-piece and small-batch production
