What tools are used for CNC lathe processing?
CNC lathe processing includes diamond tools, tool arc detection device, cutting fluid, chip device and so on. Diamond tool on the processing error of the influencing factors are the arc shape of the tool, the radius of the arc and the blade waviness (waviness) and so on. In general, the diamond tool will be trimmed into a circular arc shape, and by the tool detection device to detect its arc radius and center, the test results into the controller, the tool radius compensation for turning. If the arc of the tool is not round or the radius of the arc and the center of the error, it will cause the workpiece shape error. The edge of the blade will affect the surface roughness of the workpiece. The center of the tool arc, the movement to the set of the cutting center point, with the workpiece spindle rotation axis position and height consistent; if not consistent, in addition to the shape error will produce, but also in the workpiece center residual bump (commonly known as the navel ).
CNC cutting machine processing, often supply cutting fluid to reduce the cutting point temperature and take away the chip. Most of the diamond turning to the oil mist supply cutting fluid (high pressure air jet cutting oil). So the nozzle angle and oil, gas flow and speed will affect the cooling and chip removal effect. The most common situation is the accumulation of chips on the diamond blade, and the surface of the material being cut friction, and then the workpiece surface roughness caused a great impact. In order to avoid the production process of cutting or even chip cutting situation, can be added chip device. The principle of the chip device is the use of high-pressure air into the chip tube, so that a vacuum. The use of chip device will make the cutting point near the air generated disturbance, while the chip tube will also be due to gas flow and vibration, resulting in machine vibration and affect the surface roughness of the workpiece. Therefore, in the use of chip set device in addition to pay attention to chip effect, but also need to be careful of the impact of air disturbance and vibration.
