Cylinder Body Planing Bed Technical Parameters
A cylinder body planing bed is a type of specialized machine tool used for processing flat surfaces on large cylinder bodies, such as steam locomotives and single-cylinder engines. The machine utilizes a combination of horizontal and vertical spindles that are gradually fed down on the workpiece in order to achieve a flat and level surface throughout the entire cylinder body.
The level of accuracy achieved by the machine tool is dependent upon several different parameters including the size of the cutting tool, the speed of the spindles, and the type of material being cut. Cylinder body planing beds are typically capable of cutting materials with a machinable hardness of Rc 40 or higher, at speeds of up to 1,560 rpm.
When utilizing the right parameters, cutting a cylinder body accurately and flatly can usually be accomplished in two to three passes. The first pass is carried out at a feed rate of 0.040” per rev and a spindle speed of 500 rpm. This is followed by a second pass at a feed rate of 0.020” per rev and a spindle speed of 1,000 rpm.
Finally, the third pass is carried out at a feed rate of 0.010” per rev and a spindle speed of 1,560 rpm. Each pass should progressively provide a more accurate and square surface, culminating in a uniformly level finished product.
When machining steel or cast iron cylinder bodies with a cylinder body planing bed, a cutting depth of up to 0.090” can be achieved at a 0.010”/rev feed rate. This is done by using a carbide cutting blade with a top tip rake angle of 10 degrees and a side rake angle of 8 degrees.
The cutting blade should also be held at an axial rake angle of 10 degrees and a radial rake angle of 2.5 degrees. Finally, the proper coolant should be used to ensure an even cut and reduce the risk of damaging the cutting edge.
An example of a standard cylinder body planing bed is the TA-15 series manufactured by Yamada Machine Tools. This machine utilizes a 5 horsepower, 7 inch diamer spindle, a 7.5 inch vertical stroke, and a maximum cutting capacity of 5 inches. It also has a precision digital readout and a centralized operating control panel for easy operation.
The TA-15 series is capable of machining components with a Rc hardness of up to 40 and at a spindle speed of up to 1,560 rpm. It is ideal for machining flat surfaces on large cylinder bodies and is capable of cutting material up to 5 inches thick.
Overall, cylinder body planing beds are an important type of machine tool in the manufacturing and engineering industries. They are capable of producing flat, level surfaces on large cylinder bodies with a high level of accuracy and consistency. This accuracy is achieved through a combination of a variety of parameters, including the size of the cutting tool, the speed of the spindles, and the type of material being cut. With the right parameters, the cylinder body planing bed can produce a uniformly level surface that is both aesthetic and functional.
