Camshaft Types There are two noteworthy kinds of camshafts: Flat Type and Roller Cams. Level Tappet (lifters) are in most V8’s and actually have what resembles a level base where the cam projection contacts the tappet (lifter). Lifters are not in reality level on the contact surface. They do have a slight bend, however, it’s difficult to see. Roller Cams…
AIR GAUGING UNIT – HOW IT WORKS
HISTORY: For decades air gauging units have been used for dimensional measurements. They have been applied in many technological processes, especially in the systems of in-process manufacturing control or any type of production environment. They were initially invented in France before the Second World War by a carburetor company that was looking for a more reliable method of measuring its…
HIGH-SPEED LASER MICROMETERS
High-speed laser micrometers are non-contact measuring instruments that have a high scanning rate and are highly accurate. They help to inspect small, fragile workpieces at a high temperature, even while they are in motion or are vibrating. HISTORY: Laser micrometers are devices that are widely used for taking a precise measurement of components in not only mechanical engineering but also…
Importance of calibration in Leak Testing
Calibration is one of the many ways to achieve a precision in leak testing. Internal calibration delivers the desired results for the most leak testing applications since the leak detector properly tunes to helium and correctly reports the leak it sees. However, accuracy is influenced by numerous factors, most of which are not in control of the leak detector and…
Leak Testing For Marine And Coastal Accommodation
Marine industry and its offshore platforms including both fixed and mobile consider safety as its number one priority. One of the biggest safety issues on board is that the living quarter demands a positive pressure while the operation and especially during an emergency situation. If we see the average common safety rule, it clearly states that leak testing must be…
Laser Welding Applications Broadening Possibilities
The utilization of the lasers for welding has proved its worth since the last 35 years in the selected applications. In spite of being high in the capital cost, the precise, highly intense heat source makes the laser as a perfect choice around the tight tolerances, close fit-ups, and thin materials. Lasers produce less distortion comparatively, on a few applications…
Laser Marking In Fibre
Laser marking is nothing different than burning the leaves with a magnifying glass. We burn the leaves with magnifying glass simply by placing a lens over the leaf at the focal point of the lens; here the lens collects the sunlight. The collected sunlight then focuses on the leaf and concentrate the sunlight on the small spot of the leaf.…
Dual Axis Scanning Laser Micrometers
Dual axis, which is also called as dual-plane models, makes the measurements from the two different angles or viewpoints. The two measurement axes are perpendicular and coplanar to each other. The product that is to be measured is placed perpendicularly to the measurement field. To measure the diameter, ovality, and position of the product micrometer is typically used. Considering the…
Torque Test System
A torque testing system is specifically the range of capacity id from utilized as a device for the quality control test or to calibrate the torque controlled tools. This comprises of electronic torque wrenches, click torque wrenches, and dial torque wrenches, electric screwdrivers, pulse tools and many more. The Torque Testing involves measuring the amount of torque that is being…
Titanium Helium Leak Detection
Helium is one of the best-suited choices to find the leaks because it is non-toxic, inert, non-condensable, non-flammable and is present in the atmosphere in the trace amounts (5 ppm). Since the atomic size of the helium is small it easily passes through the leaks. Hydrogen is the only molecule smaller than helium. Hydrogen is not used in leak detection…
