Best Practices in Hardness Test

Hardness testing, as applied to various materials, is a valuable mechanical procedure that has been in effect for over 250 years. The test gives critical details around the strength and the effectiveness of the material prior to production. It is an extensive procedure employed in many industries, particularly automotive, aeroscope and quality control, among others.

The Value of Good Practices in the Tests

Good practices are paramount to achieving accurate results, meaning that the right testing techniques must be followed. In a Rockwell test, for instance, which is considered the most accurate hardness testing method, adherence to standards cannot be overstated. Poor execution of the test can give wrong readings and eventually lead to the production of a substandard item. Factors such as the area of the item, the material, specimen thickness, test location, scale limitations and the homogeneity of the specimen must be accounted for.

Factors to Consider

Before starting off with your test, ensure that the specimen and the surface are smooth and clean. A test is critical to establish the level of components and the quality control of the material. The information gathered from the test verifies the structural integrity and heat treatment, meaning that good practices should be followed. Before testing, ensure that the area does not have too much vibration. Otherwise, the performance of the tester and the readings of the hardness could be affected.

Every hardness test is dictated by the microstructure of the specimen, such as the homogeneity, the condition, the material and the size of the parts to be tested. Whichever application you choose, ensure careful preparation and execution.

A wide range of machines for steel finishing

Steel finishing is a part of the production process. For this precise part of the production process, a high-quality deburring machine is essential. Q-fin Quality Finishing is specialized in deburring. We develop, build and sell machines for the deburring, grinding and edge rounding of all metal components. Our team of industrial experts have all the knowledge and the expertise to design deburring machine with A-component. We offer a wide range of machines for steel finishing.

High quality steel finishing becomes reality

As a manufacturer you are dealing regularly with burrs. This are small nodes on the steel. These burrs are caused by the force of the cutting machines and they can damage your equipment and the steel. Even invisible burrs can impede your materials, machines and products. These problems can easily being solved with one or our deburring machines, like the F1200.  With this machine high quality steel finishing becomes reality.

One of the best changes you made

Our deburring machines deburr steel components of all shapes. The machines can even smooth parts with invisible burrs. Using a deburring machine for steel finishing will be one of the best changes you made. Want to know more about steel finishing? Then don’t hesitate to contact us for more information.

Discover the 8 benefits of carbon fabric fiber

Did you know that carbon fabric fiber is used for many applications? Carbon fabric fiber has numerous benefits. We summed up just a few of the benefits of carbon fabric fiber.

Lightweight

Carbon fabric fiber has a low density and a high strength to weight ratio. Carbon fiber is though without getting bogged down like aluminium or steel. This makes it the perfect material for applications like cars or airliners.

High tensile strength

Carbon fabric fiber has a high tensile strength. It is one of the strongest fibers of all commercial reinforcing fibers.

Low Coefficient of Thermal Expansion (CTE)

Carbon fabric fiber has a low Coefficient of Thermal Expansion. This means that the shape will not change fast when it is exposed to heat.

Long durability

Compared to metal, carbon fabric fiber has superior fatigue properties. A component what is made of carbon fiber won’t wear out fast. Even if it’s used constantly.

Dampens sound

Carbon fabric fiber dampens sounds. The material absorbs sound waves and this makes it the perfect material for dampening noise.

Heat-resistant

Carbon fabric fiber has a low thermal conductivity.  This is why it is the best choice for applications where heat-resistant material is needed.

Flexibility

Carbon fabric fiber is known for the unique strength-to-weight ratio. Due to this property, it can be used for many applications. Carbon fiber can also be molded and shaped. This is not possible with traditional material like aluminium or steel.
