What is a lathe with variable speed?

Cortex, which is a machine used to produce parts for other machines, is considered to be the oldest machine. This ability to reliably reproduce machines was one of the technologies of industrial revolution. One key to this reproducibility is to check the speed of the lathe. Basically, all lathes must have the means to change the spindle speed. Variable speed lathe refers to those lathes that have modern and accurate means to control the spindle speed.

The spindle is a device that holds a piece to be processed. It is a axis around which a piece rotates. The spindle speed is critical because it affects torque or power applied to the cutting action. Low speed generally applies more torque. The revolution per minute (RPM) is one measure of spindle speed.

The rate of section is related to the spindle speed, but is also a factor in the diameter of the work. A piece of larger diameter will have a greater cutting speed, as a longer Řezhway has been traveled in one reVoluci of the work. The hardness of the material is also a consideration. Harder materials require more cutting forces and therefore lower speeds. Due to the need for significantly different speeds, a lathe with variable speed for a particular type of material such as wood or metal will be determined.

leg -driven lathes such as pottery wheel, frequency control and foot force on the foot pump. Small trace lathes can use a simple three -stage engine and can limit speed settings to several final levels. Earlier lathe industrial variable speeds used a number of belts and flaps, including conical pulleys, to change the speed of the spindle.

Variable speeds in direct drive engines are achieved using gears or pulleys. This type of lathe with variable speed will usually have spindle speeds that are multiples, such as eight, 12, 16 and 24 times Base RPM. Changing the deceptions is to the displayOna more speed options. The gears and pulleys can be set manually or more often by dialing and levers similar to a 10 -speed or 21 -speed wheel converter.

Infinite variety of speed is available using AC motors (AC) with an infinitely variable speed transfer or newer electronic controls. Electronic variable speed control is often combined with variable speed to increase the operating range. Variable speed lathe, including electronic controls, will often be integrated into the ability to maintain a constant cutting speed, as the diameter of the piece changes, either as it is carved or its length.
