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 .

Precautions for the use of calliper

Calliper has a variety of measuring modes, easy to operate, durable, versatile and low cost, can be said to be the most common measuring tool in the tool box. However, there are a lot of matters needing attention to the correct use of calipers. Let's start with the error factors that affect the measurement results.

 

Error component

When measuring with calipers, there are many factors that cause errors, such as parallax, error caused by structure not in accordance with Abbe principle, thermal expansion caused by temperature difference between calipers and workpieces, and so on. In addition, because the caliper has no constant pressure device, it is difficult to grasp the appropriate and uniform force measurement when measuring, which is another factor causing errors.

The structure of calipers does not conform to Abbe's principle

 

The structure of calipers doesn't conform to Abbe's principle

The reading number axis and measuring axis of calipers do not conform to Abbe principle because of different axes, so when using calipers, the root or tip of the claw is used to measure, there will be a risk of increasing the measurement error. When measuring, it should be noted that the measured workpiece should be as close to the ruler body as possible (reading number axis).

 

Read the parallax of the scale

Look directly at the cursor scale when checking that it is aligned with the main scale divider.

The difference height between the vernier and the main ruler scale surface is easy to cause reading error. As shown in the figure below, if the cursor scale is viewed from an oblique direction, the error shown in the figure ΔX will result. To avoid this effect, the JIS specification states that the step height (H) should not be greater than 0.3mm.

 

 

Bending of datum end face

The bending of the ruler that guides the ruler to slide will result in an error as shown in the figure below, which can be expressed by the same calculation formula as the error that does not conform to Abbe's principle.

 

Assume that the deformation caused by bending of the guide ruler is 0.01mm/50mm, and the tip of the outside diameter is 40mm to calculate:f=40mm×0.01÷50=0.008mm

 

The relationship between measurement and temperature

The body of the caliper is generally made of stainless steel, which has the same thermal expansion coefficient (10.2±1)×10-6/K as the iron metal. The influence of the material of the measured object, room temperature and the temperature of the workpiece on the measurement should be considered when measuring.

 

Precautions in operation

The calipers are very sharp, so the instrument must be handled with care to avoid personal injury.

Avoid damaging the scale of the digital caliper. Do not encode the identification number or leave other information with the electric pen.

Maintenance of sliding surfaces and measuring surfaces

Before using calipers, wipe away dust and dirt on sliding and measuring surfaces with a soft, dry cloth.

 

Check and calibrate the origin before use

Clip a clean piece of paper between your outer PAWS and slowly pull it out. Close the caliper and make sure the vernier scale (or display) is set to zero before using the caliper. When using digital calipers, reset the battery after replacing it (zero button).

Operation after use

After using the caliper, wipe off the water and oil thoroughly. Then, lightly smear with anti-rust oil and let dry before storing. Waterproof calipers, in order to prevent the occurrence of rust after use, also need to wipe the water calipers.

 

Storage Precautions

Avoid direct sunlight, high temperature, low temperature and store in high humidity. If digital calipers are not used for more than three months, remove the battery before storage. Do not allow the outside measuring claw of the caliper to be completely closed during storage.
