Experiment 2:
Adopt the Shenyang CAK6150D of machine tool plant numerical control horizontal lathe to carry out machining, lubricated cooling adopts lathe to carry the cast-type liquid-supplying system, and nozzle is the universal water pipes of conventional plastics.The cast-type feed flow is that pure cutting fluid is supplied with non-compressed air.The NC300 stainless steel processing oil that cutting fluid adopts Lanonok Chemical (Guangzhou) Co., Ltd. to produce, and with the modification of neopelex saturated solution, both volume ratios are 9:1.For the charged influence of cutting fluid under the lubricated cooling condition of checking cast-type to machinability, at the plastic nozzle front end one contact electrode is set, contact electrode contacts with the liquid stream of nozzle ejection, makes NC300 oiliness cutting fluid charged.Used electrostatic high-pressure generator is an EST705-60 high precision high stability electrostatic high-pressure generator.

In this experiment, nozzle 12 is the induction electrode nozzle, with the cutting fluid ground connection in the liquid reserve tank of lubricating system with trace amount.Used electrostatic high-pressure generator is an EST705-60 high precision high stability electrostatic high-pressure generator.When the induction electrode nozzle applies high-pressure electrostatic, be the inventive method.As a comparison, when the induction electrode nozzle does not apply high-pressure electrostatic, can realize the not charged cutting fluid aerosol of routine micro lubricating turning method for processing.
Adopt the Shenyang CAK6150D of machine tool plant numerical control horizontal lathe to carry out machining, the technological parameter of described two kinds of method for turning sees the following form.
After 16 minutes, 32 minutes and 48 minutes, the surface roughness value Ra of workpiece is respectively 0.49 micron, 0.43 micron and 0.44 micron through described charged cutting fluid aerosol micro lubricating turning processing, processes after 48 minutes 84 microns of cutter wear of the tool flank amount VB values; After 16 minutes, 32 minutes and 48 minutes, the surface roughness value Ra of workpiece is respectively 0.56 micron, 0.69 micron and 0.82 micron through described not charged cutting fluid aerosol micro lubricating turning processing, processes after 48 minutes 114 microns of cutter wear of the tool flank amount VB values.Both compare, and after the present invention program's the charged cutting fluid aerosol micro lubricating machining, the surface roughness value of workpiece is littler, and cutter is more wear-resisting.
Experiment 4:
On the charged cutting fluid aerosol micro lubricating turning processing technology basis of experiment 3, change induction charging voltage V, be respectively 2000V, 5000V and 15000V, 48 minutes process times, other technological parameters are constant.Under 1000V, 5000V and the 15000V induced voltage through described charged cutting fluid aerosol micro lubricating turning processing after 48 minutes, the surface roughness value Ra of workpiece is respectively 0.71 micron, 0.56 micron and 0.79 micron, and cutter wear of the tool flank amount VB value is respectively 101 microns, 96 microns and 107 microns.
Induction charging voltage is preferably 1000V to 20000V.Induced voltage is low excessively, and the carrying capacity of cutting fluid is little; Induced voltage is too high, and the induction electrode edge produces the corona discharge phenomenon, and the induction that influences cutting fluid is charged.
Experiment 5:
On the cutting fluid aerosol micro lubricating turning processing technology basis of experiment 3, change cutting fluid mist flow L, be respectively 10mL/h, 60mL/h and 100mL/h, 48 minutes process times, other technological parameters are constant.Parallelly simultaneously carry out not charged cutting fluid aerosol micro lubricating turning processing contrast experiment, i.e. induction charging voltage 0V, the cutting fluid mist flow is respectively 10mL/h, 60mL/h and 100mL/h, and 48 minutes process times, other technological parameters are constant.
Under 10mL/h, 60mL/h and the 100mL/h flow through described charged cutting fluid aerosol micro lubricating turning processing after 48 minutes, the surface roughness value Ra of workpiece is respectively 0.70 micron, 0.51 micron and 0.62 micron, and cutter wear of the tool flank amount VB value is respectively 104 microns, 86 microns and 98 microns.
Under 10mL/h, 60mL/h and the 100mL/h flow through described not charged cutting fluid aerosol micro lubricating turning processing after 48 minutes, the surface roughness value Ra of workpiece is respectively 0.97 micron, 0.85 micron and 0.88 micron, and cutter wear of the tool flank amount VB value is respectively 122 microns, 116 microns and 119 microns.
This is because mist flow when low, and the charged aerosol amount that arrives at cutting zone is few, the lubricated cooling effect of influence; When mist flow is big, increase although arrive at the charged aerosol amount of cutting zone, the charge-mass ratio of cutting fluid reduces, and also influences the lubricated cooling effect of charged aerosol.Therefore, the cutting fluid flow is preferably 5mL/h to 150mL/h, to guarantee lubricated preferably cooling effect.
Change under the cutting fluid flow condition, with charged cutting fluid aerosol micro lubricating turning relatively, utilizes not charged cutting fluid aerosol micro lubricating turning processing after, the surface roughness value Ra of workpiece and cutter wear of the tool flank amount VB value be increase to some extent all.Therefore, utilize charged cutting fluid aerosol micro lubricating technology to have better lubricated cooling effect.
Experiment 6:
On the cutting fluid aerosol micro lubricating turning processing technology basis of experiment 3, change spray pressure P, be respectively 0.1MPa, 0.6MPa and 1.0MPa, 48 minutes process times, other technological parameters are constant.Parallelly simultaneously carry out not charged cutting fluid aerosol micro lubricating turning processing contrast experiment, i.e. induction charging voltage 0V, spray pressure is respectively 0.1MPa, 0.6MPa and 1.0MPa, and 48 minutes process times, other technological parameters are constant.
0.1MPa, under 0.6MPa and the 1.0MPa air pressure through described charged cutting fluid aerosol micro lubricating turning processing after 48 minutes, the surface roughness value Ra of workpiece is respectively 0.81 micron, 0.65 micron and 0.91 micron, and cutter wear of the tool flank amount VB value is respectively 111 microns, 96 microns and 120 microns.
0.1MPa, under 0.6MPa and the 1.0MPa air pressure through described not charged cutting fluid aerosol micro lubricating turning processing after 48 minutes, the surface roughness value Ra of workpiece is respectively 1.03 microns, 0.87 micron and 1.16 microns, and cutter wear of the tool flank amount VB value is respectively 127 microns, 119 microns and 132 microns.
This is because air pressure when low, and cutting drop grain diameter is big, and lubricant effect is poor, and compressed air to the cutting zone cooling effect also a little less than; When air pressure was high, although cutting drop grain diameter diminishes, the speed of aerosol increased, and is unfavorable for the absorption of drop in cutting region, and it is poor to influence lubricant effect.Therefore, compressed air air pressure is preferably 0.05MPa to 1.2MPa, to guarantee lubricated preferably cooling effect.
Change under the air pressure conditions, with charged cutting fluid aerosol micro lubricating turning relatively, utilizes not charged cutting fluid aerosol micro lubricating turning processing after, the surface roughness value Ra of workpiece and cutter wear of the tool flank amount VB value be increase to some extent all.Therefore, utilize charged cutting fluid aerosol micro lubricating technology to have better lubricated cooling effect.

Under 5000V, 15000V, 25000V and the 30000V voltage through described charged cutting fluid aerosol micro lubricating turning processing after 48 minutes, the surface roughness value Ra of workpiece is respectively 0.78 micron, 0.59 micron, 0.46 micron and 0.50 micron, and cutter wear of the tool flank amount VB value is respectively 109 microns, 95 microns, 87 microns and 89 microns.
Corona charging voltage is preferably 3000V to 30000V(and makes 35000V into).Near the air ionization deficiency brownout, corona electrode, the charged effect of influence cutting drop; Voltage increases, and electrode produces corona discharge, improves the charged effect of cutting drop; Corona voltage further increases, if smear metal is nearer apart from the corona nozzle when metal works separates, causes short circuit easily, and the electrostatic high-pressure generator overload quits work.
Experiment 8:
On the cutting fluid aerosol micro lubricating turning processing technology basis of experiment 3, adopt the contact charging mode charged to cutting fluid, voltage is respectively 5000V, 15000V, 25000V and 35000V, and 48 minutes process times, other technological parameters are constant.During contact charging aerosol micro lubricating, guarantee the insulation of aerosol generation systems.Under 5000V, 15000V, 25000V and the 35000V voltage through described charged cutting fluid aerosol micro lubricating turning processing after 48 minutes, the surface roughness value Ra of workpiece is respectively 0.58 micron, 0.51 micron, 0.47 micron and 0.48 micron, and cutter wear of the tool flank amount VB value is respectively 91 microns, 87 microns, 86 microns and 88 microns.
Contact charging voltage is preferably 2000V to 40000V.Brownout, the charged deficiency of cutting fluid.In 15000V to 35000V scope, the processing characteristics difference of contact charging aerosol micro lubricating is little.But owing to require the insulation of aerosol generation systems, security requirement improves during contact charging.
Cutting fluid flow and compressed air pneumatic parameter are equal to the lubricated processing of induction charging aerosol, narration no longer one by one substantially to the influence of lubricated processing of corona charging aerosol and the lubricated processing of contact charging aerosol.
