The mechanical linkage can become quite elaborate, as it evenly distributes force from one pressurized air cylinder to 8 or 12 wheels. The piston is connected through mechanical linkage to brake shoes that can rub on the train wheels, using the resulting friction to slow the train. In the air brake's simplest form, called the straight air system, compressed air pushes on a piston in a cylinder. Overview Straight air brake A comparatively simple brake linkage A subsequent reduction or loss of air pressure causes each car to apply its brakes, using the compressed air stored in its reservoirs. Full air pressure causes each car to release the brakes. The Westinghouse system uses air pressure to charge air reservoirs (tanks) on each car. In various forms, it has been nearly universally adopted. The Westinghouse Air Brake Company was subsequently organized to manufacture and sell Westinghouse's invention. Modern trains rely upon a fail-safe air brake system that is based upon a design patented by George Westinghouse on April 13, 1869.

You should choose the spindle power according to the materials that you need to machine.įor machining wood, plastic, laminate, or aluminum with cutters up to 5mm, the spindle with 0.8 kW power and 24,000 rpm is sufficient.įor using cutters up to 8mm you would need a 1kW spindle, for cutters up to 12mm, a 3.3kW spindle, and for cutters up to 16mm, you should have a 5.6 kW spindle.įor steel, you should choose a lower rpm spindle (15,000 to 18,000 rpm) and a 3.3 kW spindle for cutters up to 10mm, a 5.6 kW spindle for cutters up to 12mm, a 7 kW spindle for cutters up to 16mm, and a 10 kW spindle for cutters up to 20mm.The examples and perspective in this article may not represent a worldwide view of the subject. Horsepower refers to the amount of work being done. Spindle power is the value of torque multiplied by rotational speed. However, it does not mean that the spindle is always running at these revolutions. Since there is minimal physical manipulation, operators can achieve greater expertise in just a few months.ĥ×10 CNC Routers are highly efficient, cost-effective, and reduce waste, which in turn increase production capacity.Ĭhoosing the right spindle is extremely important.ĭepending on your professional use, you can choose from a wide range of spindle revolutions and power. These routers can produce hundreds of pieces that are exactly the same and are ideal for companies that emphasize quality assurance. 5×10 CNC Routers eliminate waste caused by human error, producing thousands of identical pieces without wastage. Standard routers do not have the precision of a 5×10 router, and hence there is a constant threat of errors in workpieces. However, a 5×10 CNC Router can create such pieces with ease. Some of these benefits include:Ĭreating large pieces like stair risers is difficult with standard routers, especially in terms of accuracy. A 5×10 CNC Router offers incredible accuracy at a high rate of speed and many other benefits.
