Embodiment 1
[0024] Adopt processing equipment of the present invention to carry out such as Figure 4 The ultra-precision machining of the workpiece shown in (a), the workpiece material is glass ceramics, the specific processing process is as follows:
[0025](1) Since the workpiece material is glass-ceramic, the compound processing method of ultrasonic-assisted grinding is used for processing this material. Using industrial computer programming to control the processing process;
[0026] (2) First, rough machining the workpiece, select an electroformed diamond grinding head with a grain size of W120, and fix it on the front end of the spindle of the machine tool (such as image 3 shown).
[0027] (3) Fix the unprocessed workpiece blank on figure 1 On the precision air flotation workbench shown (such as figure 1 shown).
[0028] (4) The processing parameters are set as: spindle speed 3000rpm, knife penetration 0.1mm, ultrasonic vibration frequency 25kHZ, cooling method water cooling,...
Embodiment 2
[0033] Carry out such as by processing equipment and processing method of the present invention Figure 4 The ultra-precision machining of the workpiece shown in (b), the workpiece material is hard alloy, the specific processing process is as follows:
[0034] (1) Since the workpiece material is cemented carbide, the composite processing method of ultrasonic-electric discharge-milling-grinding is used for processing this material. Using industrial computer programming to control the processing process;
[0035] (2) Fix the unprocessed workpiece blank on figure 1 On the precision air flotation workbench shown (such as figure 1 shown).
[0036] (3) Firstly, the workpiece is roughly machined, and the brass electrode is fixed on the tool handle at the front end of the spindle, and the electrode (+) and workpiece (-) are respectively connected to an external power supply (such as image 3 shown).
[0037] (4) The processing parameters are set as: EDM voltage 150V, pulse width / ...
