Embodiment Construction
[0046] Such as figure 1 with figure 2 The processing system shown includes a microcomputer, a controller, a micro-feed compensation device, a walking board, a lathe guide rail, an inductance micrometer, a dual-frequency laser interferometer, an outer diameter detection device and shaft parts, and the Z axis is parallel to the processing guide rail , X-axis and Z-axis are perpendicular to the horizontal direction, the CNC lathe is 180CCN CNC lathe, the positioning error of the machine tool is 2μm, and the Z-axis of the CNC lathe is commonly used for strokes of 400mm to 190mm for shaft processing.
[0047] Step 1. Install the beam splitter of the dual-frequency laser interferometer on the extended end of the micro-feed compensation device, and fix the mirror on the machine tool. The CNC lathe moves along the Z guide rail at a constant speed from the coordinate 400mm to 190mm, and stops for 10 minutes at intervals of 10mm. Seconds, after the machine tool and the measuring syste...
