The Worlds First Dual Load Controlled Tribometer

Irvine CA, February 28, 2018 – The Nanovea T2000 is the worlds first dual load controlled Tribometer providing vertical force oscillation at frequencies up to 150Hz. It combines advanced pneumatic technology with a state of the art linear electromagnetic stage to provide controlled loading from 1mN to 2000N during rotative and linear testing. Pneumatic is used from 5 to 2000N offering multiple advantages compared with age old spring/motor technologies used on other systems. With spring/motor technologies, the load sensor is typically placed behind the spring. This means that it is not measuring the actual variation of load applied on the surface during the test. The T2000 measures the load by a direct connection between the ball holder and the actual load cell. This ensures that the load measured is actually the load applied on the surface. The linear electromagnetic loading system of the T2000 can apply a vertical force of 0.2 to 20N at frequencies up to 150Hz. As an example, the normal load can be increased from 0 to100N with the pneumatic technology and then the linear motor can vary the load from 90 to 110N and up to 150 times per second. This gives the unique capability of superposing a control fatigue or vibration level to the main constant force applied by the pneumatic system. This electromagnetic linear stage can also apply directly very low loads from 1mN to 5N to complete the full range.

Now the World’s Leading Micro Mechanical Testing

Irvine CA, January 31, 2018 – Now the world’s leading micro mechanical testing. Automatic, accurate and fast hardness and elastic modulus results obtained from depth versus load data are truly a giant leap compared to traditional hardness testers. This past century technology was based on visual inspection when accurate depth sensors were not available. Therefore, today there is absolutely no advantage with using outdated traditional hardness testers. The Nanovea CB500 with Micro Module is faster, easier, more accurate particularly at low loads and more repeatable. Testing can be performed on any material including very elastic material or on surfaces where identifying the indent is challenging. Not only providing hardness and elastic modulus but also a wide range of testing such as creep, stress-strain curves, yield strength, fatigue, fracture toughness, scratch and marring resistance, plastic/elastic deformation, wear rate and friction coefficient.

Precision Machined Part Inspection With 3D Profilometry

Precision machined parts manufacturing calls for stringent inspection to ensure product quality and repeatable production standards. The 3D surface inspection of the part compared to CAD model is essential to verify part tolerance and machine quality. Moreover, during the service time, wear and tear of the parts may create surface defects such as scratches, dents and cracks. The part needs to be replaced when the deviation from the required specification is over the tolerance limit. Unlike a touch probe technique, the Nanovea ST400 Profilometer performs 3D surface measurement without touching, making it possible to precisely scan parts with a complex shape at a high speed.

Mechanical Properties of Hydrogel using Nanoindentation

In this application, the Nanovea Mechanical Tester, in Nanoindentation mode, is used to study the hardness, elastic modulus and creep mechanical properties of a Hydrogel sample. In this case a sample of Hydrogel can simply be placed on a glass slide due to the softness and low load being used to test; testing could also be preformed while in liquid. For this soft material a 3mm spherical tip will be used. This is to give good information on the Hydrogel and not on surface properties that might be different. This can be studied using a shaper Berkovich tip.

Fresnel Lens Dimension Measurement Using 3D Profilometry

A Fresnel lens is extensively employed in industry, such as automobile, lighthouses, solar energy and optical landing system for aircraft carriers. The inexpensive production of Fresnel lenses can be completed by molding or stamping them out of transparent plastic. The service quality of the Fresnel lenses mostly depends on the precision and surface quality of the concentric rings lenses. Unlike a touch probe technique, the Nanovea Profilometer performs 3D surface measurement of the sample without touching, avoiding the risk of making new scratches during the surface measurement. The chromatic confocal technique is ideal for precise scan of a complex shape, such as lenses of different geometry.

Tribology Study of Dental Dog Treat Friction

Flavored dental treats have been demonstrated as an effective, comfortable and easy to use method for dog dental cleaning. The Flavorful and chewy dental treats make teeth and gums cleaning an enjoyable procedure. During the chewing mechanical actions, the dental treat creates friction against the surface of the teeth to remove tartar and bacteria films. A reliable tribology study is needed to quantitatively compare the effectiveness of dog dental treats of different surface texture and roughness, and to provide insight of the correlation of the surface roughness, texture and friction to facilitate the R&D and quality control of the dental treat production.

Flatness Measurement of Screen Using Fast 3D Profilometry

Flatness measurement is an important geometric surface quality in the manufacture of precision parts and assemblies. Flatness of the surface plays a vital role in the end use of the product. For example, the parts that are connected in an air-tight or liquid-tight manner across a surface area require stringent surface conditions of superior flatness at the contact face. Flatness of the screen is critical to the functionality and aesthetics of electronic devices such as cellphones, pads and laptops. Any imperfection of the screen flatness can create negative user impression and experience of the product.

Microindentation Mapping on Glass

Microindentation mapping has proven to be a critical tool for surface mechanics related studies. Fracture has typically been evaluated by measuring the dimension of the cracks of the indent, and the use of acoustic emission during testing has been an overlooked and valuable tool. Microindentation with the measurement of Acoustic Emissions (AE) provides a reliable and user-friendly method to track the fracture behavior and intensity during loading and unloading process.
