 Automatic Tool Changer An automatic tool changer often referred to as an ATC, is used to improve both the production and the tool carrying capacity of a computerised numerical control or CNC machine tool. It does this by allowing the machine to work with various different tools. As such it is part of the process to achieve full automation. General Description View fullsize A simple CNC machine will be made to work with a single tool. More complex machines are capable of working with larger numbers of tools. However, for a machine to use more tools an ATC must be provided. The array of tools are stored within a magazine which allows the machine to access a wider variety of them without the need for an operator. An automatic tool changer is generally comprised of a base, arms with a gripper, a tool holder and a support arm as well as the tool magazines. An ATC is capable of increasing the speed and accuracy as well as the reliability of a CNC machine but it does have certain require...

  Rugged crossovers, trucks, and SUV s  come in all types, sizes, and designs and are equipped with a variety of standard features and options. These adventure vehicles handle both on-road and off-road excursions with ease. The vehicle's portal gear axles provide high ground clearance. These vehicles are generally characterized by having large tyres with deep, open treads, a flexible suspension (high articulation), or even caterpillar tracks. Because of their versatility, several types of Motorsports involve racing off-road vehicles. OHVs are specifically designed for off-road use and can be enclosed or open air. Quad bikes, dirt bikes, dune buggies and other types of all-terrain vehicle (ATV) are often included as types of off highway vehicles, although their function is very different from a motor vehicle designed for industrial and farming use. ADVENTURE is powered by a low-consumption 2500cc diesel engine and configured as a 10-passenger vehicle...

  A  Coordinate Measuring Machine  is defined by the ability of its probe. As with CMMs, there are several types of probes available. There is the contact probe, which measures the workpieces by making contact with them. The non-contact probe that employs lasers or machine vision probes which scan with optical sensors. Contact probes are a more accurate way of measuring. However, the laser or machine vision probes are far quicker to use, while still holding a high degree of accuracy. There are also multi-sensor probes which combine both touch and optical scanning, giving the benefit of both types in one probe. Coordinate Measuring Machines: Contact Probes The two most common contact probes are Touch Trigger Probes and Analog Scanning Probes. Touch Trigger Probes: A touch trigger probe has a stylus that is attached to a bearing plate. This is then connected to pressure sensors inside the housing of the probe. Each time the probe makes contact with the workpiece, it generat...

  Open Coiled Helical Springs:  These helical springs are designed to resist compression, which is they are known as  compression springs . These springs are not wound tightly, and have a high pitch. This results in large spaces between the coils, which also makes the springs very recognizable. Hence, no two turns of a spring will lie on the same axis of the helix. The turns of these springs are located at inclined angles towards the helical axis. Some typical applications include ball point pens, valve assemblies in engines, car suspension systems, pogo sticks, etc. Closed Coiled Helical Springs:  Designed to resist stretching and twisting, these springs are also known as  tension/extension springs . These springs feature an eye or a hook at the end for attachment. These springs can endure stress caused by high torsion or bending. The coils are closely wound to each other, and lie on the same axis of the helix. The turns of this spring lie at 90 degrees to the ...

  A lathe is a tool that is used to rotate the material being worked on its axis to allow the performance of operations such as cutting, deformation and turning through the use of tools applied on the work-piece. For mass production, multi spindle lathes are preferred due to the fact that their production is as much as four to six times higher compared to what a single lathe machine can offer you. Their accuracy is also much higher and they save on a lot of time. Multi Spindle Automatic Lathe This type of machine has the ability to provide various types of operations which include boring holes, turning, chamfering, threading, grooving as well as drilling and this is done by moving the piece that is being worked on between six to eight positions in the machine. This tool can produce a very fast  cycle time  by dividing a single process to six or eight times, which enables you to complete a process fast and efficiently. This machine is much better than the single spindle la...

Law of Conservation of Energy Energy cannot be created or destroyed, but it can only change from one form to another. The law of conservation of energy  does not distinguish between valid and wasted  energy . The law neglects ‘losses’ from the closed system into the environment. In an energy conservation process, energy is transmitted from one or more forms to another form forms resulting in specific work, heat transfer and energy loss. In a closed system containing a certain quantity of matter and energy,  several energy  transformations may occur from one form to another. The total mass and energy in the closed system remain unchanged. Some examples of energy transformations: Turning on a car’s engine transforms the  chemical energy  in gasoline into the mechanical energy that powers the engine, with heat energy released as a by-product. Trees and plants transform radiant energy from sunlight into chemical energy in simple sugars through photosy...

  15 Greatest Motorcycle Brands | History & Facts It’s hard to say what it is, but motorcycles are impressive works of art and, at the same time, brilliant pieces of engineering. Since the first series production motorcycle in 1894, the two-wheeler has grabbed the attention of enthusiasts worldwide. Competition has only got more fierce through the years, with more motorcycle manufacturers trying to one-up against their rivals. The past century has seen the birth of numerous iconic motorcycle makers and their iconic products. It is hard to describe any one manufacturer as the greatest. Most motorcycle companies have had moments of triumph either in the market or on the racetrack. So we have compiled this list of 15 of the greatest motorcycle makers ever. Each of these companies has contributed to perfecting the art of motorcycle making in one way or the other. 1. Suzuki The brand Suzuki was founded in 1909, initially manufacturing silk weaving looms. Suzuki started building bike...
