How does the wood cnc cut machine set the knife?

The coordinate system of the screw-disc tool changing machining center is determined after the engraving machine leaves the factory, but the installation position of the work piece within the machining size range of the machine tool is arbitrary. On the knife. ATC automatic cnc router can be divided into manual tool setting and automatic tool setting. Automatic tool setting machine is generally equipped with tool magazine, row tool changer or disc tool changer. The automatic tool setting instrument is controlled by software to automatically adjust the initial position of the tool and the position of the engraved work piece. Manual tool setting requires the operator to manually adjust the position of the work piece with the tool setting block.

Simply put, tool setting is to tell the CNC engraving machine where the work piece is clamped on the worktable, which is achieved by determining the position of the tool setting point in the machine tool coordinate system. The tool setting point is the reference point used to determine the position of the work piece coordinate system in the machine tool coordinate system after the work piece is positioned and clamped on the machine tool. In order to ensure the correct processing, when compiling the program, the correct point should be set reasonably. Generally speaking, the tool setting point of the CNC router wood cutting machineryshould be selected on the origin of the work piece coordinate system, which is conducive to ensuring the tool setting accuracy and reducing the tool setting error. The tool setting point or tool setting reference point can also be set on the fixture positioning element, so that the positioning element can be used as the tool setting reference for tool setting, which is beneficial to the accuracy of the work piece coordinate system position during batch processing.

The accuracy of the tool setting will directly affect the machining accuracy. Therefore, the tool setting operation must be careful, and the tool setting method must be adapted to the machining accuracy requirements of the parts. When the machining accuracy of the parts is high, the dial indicator can be used to find the correct tool. Using this method for knife setting requires a longer time each time and is less efficient. Many CNC machining centers currently use new methods such as optical or electronic devices to reduce formulas and improve accuracy.

When the CNC water pump wood cutting machine is processing different plates, attention should be paid to the screening of the strength of the lower knife and the power of the spindle. For solid wood engraving, attention should be paid to the thickness, hardness and other characteristics of the solid wood. For harder ones, use a spindle with a higher power, generally above 3kw, and for a softer one, use a spindle with less power; when carving ordinary wood, the lower knife should be deep, because The female groove is deep; when processing plywood, the lower knife must be slow, and the lower knife should not be deep, because the plywood itself is relatively thin.
