"1" Hitachi Seiki HT20S2 CNC lathe is equipped with automatic measurement tool compensation function, first select the tool number to be measured, and go to the position, you can manually enter the tool number and execute it in MDI mode, so that you want to measure When the tool number reaches the position, the measuring device that automatically measures the tool compensation is opened, and the x and z directions of the tool are respectively touched by the hand wheel to the corresponding measuring head. After encountering, the buzzer will make a sound and it will automatically compensate the measured tool. Enter OFSET, then close the measuring device (note that the hand cannot touch the measuring head to avoid misoperation), reselect the tool number to be measured and repeat the above procedure to measure the measured tool once.
"2"WILLMINW203 It is a turning center with auxiliary measuring tool compensation. It is a straight row knife loading. The table of the loading knife is the same as that of the vertical machining center. The tool is mounted on the table in a flat row (special knife The frame and turret-type tool holder are two concepts. When the knife is opened, the pneumatic switch is opened so that the knife-fixing device can be extended. The knife-setting projector is installed and the power supply is plugged in (the projector is the machine's own). Align the tool to be measured with the center line of the projector, select the tool number to be input twice in OFSET to complete the tool X, Z compensation input, select another tool to repeat the above process and measure the rest of the tool . {Note: The straight-line type tool has no tool number, and the tool number must be set by oneself. If T1 is set to input the tool compensation, it will be automatically processed according to the set T1 compensation plus/minus at the time of processing.}
The advantages of the above automatic and auxiliary measurement tool compensation methods are convenient, and the error is basically within the range.
Automatic knife setting method for two CNC lathes
The tool compensation of the general CNC lathe is two kinds of commonly used after the input of the measurement and after the direct test cutting the surface of the workpiece after calculation. Now I introduce the use of CNC lathes with automatic tool compensation:
