How to install the workpiece in CNC milling machine processing?

When installing the workpiece, if you need to use a shim, a copper plate of a certain thickness (about 5mm) should be placed between the work surface of the machine tool and a thin copper sheet between the shim and the work table to prevent the CNC milling machine from processing the work surface and the workpiece Indentation occurs on the surface. When using the shim, pay attention to the shim and the fixing screw to be as low as possible, and the shim should be placed outside a certain area of the workpiece processing range to avoid the impact of the shim on the cutter head and tool chuck. Cause damage. When loading and unloading workpieces, please handle with care to minimize the frictional movement of the workpiece on the work surface. It is forbidden to drag the workpiece on the work surface of the machine tool with the corners of multiple workpieces (this will severely scratch the work surface of the machine tool and affect the processing surface of the CNC milling machine. Flatness); It is forbidden to place sleeves, screw wrenches, screws, rubber hammers, oilstones, files and other tools on the work surface of the machine tool to prevent damage to the work surface of the CNC milling machine.

Operation method of gantry milling: Before starting up, first check whether the lubricating oil is appropriate, whether the processing state of gantry milling machining center and CNC milling machine is normal, then turn on the power of the machine tool (when turning on the power of the machine tool, turn the knob from "Off" to "ON" ”Position), then turn on the power switch on the control panel and turn out the emergency stop button.

After starting up, the CNC milling machine first returns to the machining origin and the tool magazine returns to zero. For gantry milling machining center, first check whether the tool relative to the workpiece position is safe before the origin return, and then determine how to return to the origin (the machine tool can return to the zero position in the order of the axes respectively). Select ZeroReturn (machine origin return); select ArcManual position → press tool magazine Back to zero. Check the shift record to clarify today's tasks and precautions. For each workpiece, check whether the processing program is complete, whether the tools used are complete and intact, and the tools are numbered, and the tool number is written on the tool with a marker. Easy to check. Prepare the workpiece and fixture according to the programmer's requirements, and determine the method of clamping the workpiece (the working bottom surface should be smoothed with oil stone).
