How Do You Test the Quality of Cermet Turning Inserts

Cermets are advanced cutting materials that are widely used in machining applications, specifically in turning processes. These materials have become increasingly popular due to their excellent wear resistance and high cutting speeds. However, the quality of cermets can vary, and it is essential to test the inserts to ensure they meet the required standards.

One of the primary factors to consider when testing the quality of cermet turning inserts is the composition of the material. Cermets are typically composed of a ceramic matrix and a metal binder phase. The composition of these components determines the performance characteristics of the insert, such as hardness, toughness, and wear resistance.

To test the composition, various techniques can be employed, including spectroscopy and microscopy. Spectroscopy can provide information about the chemical composition of the material, while microscopy can reveal the microstructure and distribution of the different phases. These tests can help ensure that the cermet SEHT Insert inserts are made from the desired composition and meet the required specifications.

Another critical aspect to test is the physical and mechanical properties of the cermet inserts. These properties include hardness, toughness, and thermal conductivity. Hardness is a measure of the material's resistance to indentation, while toughness relates to its ability to absorb energy without fracturing. Thermal conductivity is important to ensure that the heat generated during machining is adequately dissipated.

There are several methods to test the physical and mechanical properties of cermet inserts. Hardness can be measured using a hardness tester, which applies a known load and measures the depth or size of the resulting indentation. Toughness can be evaluated through impact tests, WCMT Insert where a known amount of energy is applied to a notched sample, and the resistance to fracture is measured. Thermal conductivity can be determined using specialized equipment that measures the flow of heat through the material.

Furthermore, the cutting performance of cermet turning inserts can be assessed through machining tests. These tests involve using the inserts in an actual turning process and measuring performance indicators such as cutting speed, tool life, and surface finish. Machining tests provide valuable information about the wear resistance, chip formation, and overall performance of the inserts.

In addition to conducting these physical and mechanical tests, it is essential to ensure that the cermet turning inserts meet the required dimensional tolerances. These tolerances include parameters such as insert size, tip radius, and cutting edge angle. Dimensional accuracy is crucial to ensure proper fit and performance when using the inserts in a turning operation.

The quality of cermet turning inserts can also be tested through visual inspection. This involves examining the inserts for any defects such as cracks, chips, or uneven surfaces. Visual inspection can be done using specialized equipment, including microscopes and digital imaging systems.

In conclusion, testing the quality of cermet turning inserts is essential to ensure their performance and reliability in machining processes. By conducting tests on composition, physical and mechanical properties, cutting performance, dimensional accuracy, and visual inspection, manufacturers can ensure that the inserts meet the required standards and deliver consistent results in turning operations.

5 Necessary Aspects of Aluminum Rapid Prototyping


Posted on: Aug 1, 2023| By Candy, WayKen Marketing Manager

What is Aluminum Rapid Prototyping?

The modern design factors and marketing realities Cast Iron Inserts push the engineers and companies to come up with their finished products by spending the least possible time and budget during the design phase. In order to achieve this feat, rapid prototyping is used to fulfill these market demands. Aluminum rapid prototyping comprises two distinctive techniques. The additive prototyping and subtractive prototyping. Additive aluminum prototyping, especially CNC aluminum is the process under which the virtual 3D designs are used to build up the prototype via depositing aluminum layers. The prototypes are built from bottom up. Laser-sintering and 3D printing are best-known examples of additive rapid prototyping.

Subtractive aluminum prototyping is the process via which prototypes are built through repetitive cutting of the material from a solid block of Cutting Inserts aluminum. Under this process, prototypes are made from top to bottom. Subtractive prototyping is done via CNC machining which includes milling, turning, milling and other standard machining processes.

Subtractive rapid prototyping is said to be faster, economical and better as compared to its counterparts. And why not your company goes for it as compared to laser-sintering, 3D printing and other available techniques in the market.

A brief about aluminum and its alloys

Aluminum is said to exhibit low density but higher strength, the strength that surpasses that of high-quality steel. It also has excellent plasticity, high resistance to corrosion as well as exceptional electroplating and welding characteristics. Aluminum being relatively cheap and abundant in nature reduces the overhead cost due to faulty production or prototypes wasted due to bad design. It can also be easily recycled which further aids in cheaper manufacturing. This material also has high toughness and less deformation after manufacturing, making it an ideal material to be used by many companies for prototyping purposes.

How is Aluminum Rapid Prototyping Carried Out?

As discussed earlier, there are a number of traditional and modern ways to have your prototype come into existence. Here we will be discussing the CNC manufacturing technique for Aluminum rapid prototyping.

Depending on what sort of machine you are using for the CNC of prototype, determines what process you have to carry out for effective aluminum prototyping. Generally, you have to feed in the system with a CAD product design and have it converted to vectors so that the machine can read off the coordinates. Once the file is uploaded and the vectors are traced, the tool and the tool path are selected to cut the block into shape. It can be a .75-inch core box bit or .25-inch v-bit. Along with the cutting depth for the aluminum prototyping, the speed of cutting can also be altered.

Once the tool, its speed and the depth are selected, the toolpath is then fed to the CNC machine. You can either cut outside the vectors, inside the vectors or trace the vectors. The method of cutting varies drastically and is based upon the machinist, the machine and the design complexity. The vectors are then converted to G-code and the centre of the block is determined. The CNC router is jogged right at the centre of the block and touches the face of it. This point is set and termed as absolute zero. The CNC machine then reads off the G-code and starts the prototyping process.

When machining aluminum, one of the biggest failure modes that exist is its flakes adhering to the cutting edge of the tool. This degrades the cutting ability which adversely affects the prototyping output. The cutting tool and material coating on the tool, both are carefully selected in order to reduce the chances of aluminum build up on the cutting tool.
