Clearance dogs actual it is the frequency conversion speed that point to. Frequency conversion principle is such: Obtain voltage of a sampling by discharge clearance, go controlling a frequency and voltage to be close to the oscillator of linear change with this voltage, the operation that the pulse that it outputs regards controller as directly and feed are opened stop signal, this came true to be opposite by clearance voltage the control of feed speed. What say normally dog the extent range that degree of tightness changes that sampling voltage that offers to the oscillator artificially namely. Dog adjusting the basiccest principle is the treatment to gain stability, want to stabilize only, speed, bright and clean degree have assure. Because the automata range of frequency conversion circuit is very big, be in usually, it is very not important that the frequency conversion on face plate adjusts located position, put where to be able to be machined. But efficiency of the cut below certain and specific situation and quality, still have major concern with frequency conversion high speed. The method of timing is: Arteries and veins of make choice of between wide, arteries and veins, after throwing a number of pipe, observing the volmeter of clock and ammeter, the adjustment of frequency conversion speed can make the indication of the watch fluctuant inside certain limits, in that paragraph of limits with lesser electric current, those who adjust along with move the meeting is more acute, adjust toward quick way can have a paragraph slower, park is slow the boundary with delicacy is relatively appropriate. Also can saying is tone go to slightly again when the position that machines normally to not quite acute already Dan Shangneng callback a bit. This is the average data that point to, normal thickness. A few righter special material or exceed thick treatment, criterion frequency conversion is adjusted due specific aim. Be like the material of low electrical conductivity, divide outside raising amplitude of high frequency source, still should start sampling voltage rises, make dog become loose. The treatment of big ply, also should make frequency conversion rate a bit a few slower, would rather appear a few sky carry pulse, also should give out to clean clearance adequately and restore the time of insulation. Had dogged to tighten, the meeting on certain level makes discharge clearance decrescent, the black and white stripe of plating Fu becomes shallow, but it is black and white color merely shallow, bright and clean spend and had done not have. Because corrode hole and inverting stripe are same, it is easier short circuit only just. If filar pine or tension not divide evenly, cause exceed feed after that long short circuit, bright and clean degree, efficiency was done not have. Dog the treatment that clearance affected line cut machine tool directly, dog space is too little, appear easily cut short circuit, cut has streak. Dog too loose, do not dog to reach the designated position, cut is not stable. Anyhow, in process of line cut cut, had adjusted dog clearance, very important. At present treasure Ma numerical control, the BMXP that roll out controls a system, to the treatment of groovy height, want VF to choose only " 0 " the system will be automatic according to cut circumstance adjustment dogs, realized intelligence to change.
