How to select a good finishing edm hole drilling machine?

There are two types of edm hole drilling machine processing: CNC and Manual processing. CNC Drill EDM can generally use translation processing, while manual hole popper edm cannot perform translation processing. The size after machining is determined by the current of finishing. The processing hole diameter is ∮0.3-∮3mm. Generally, translation processing is not required in roughing, and the electrode scaling is 0.15-0.3mm on one side. It has good electrical conductivity, fast processing speed, and can save discharge time. The price is generally one-tenth of that of copper material. When determining the amount of electrode scaling, it should be selected reasonably according to the processed product. The spindle lift has a fast up and down function. The x, y and z axes of the table are equipped with digital display devices. In terms of use, in addition to the hole processing of the workpiece, it includes the small hole processing of aircraft parts or engines that can use heat and wear resistance in the processing of small parts, the processing of various nozzles, porous perforation processing in molds, high Precision electronic parts molds, etc., all need to rely on full numerical control or edm hole drilling machine with intelligent error correction function to achieve.

Taking the following measures will improve the finish of the edm hole drilling machine to a certain extent:

• Appropriately reduce the pulse width and peak current, that is, reduce the size of the pit.

• The guide wheel and bearing maintain good precision and smooth operation, reduce jitter, and keep the displacement of the electrode movement track to a minimum.

• The working fluid is definitely beneficial to the perforation efficiency of the EDM.

• Add a splint to the upper and lower sides of the workpiece that is too thin, so that the reversing stripes are buffered within the range of the splint.

• Stable XY motion, good follow-up fidelity, and non-blocking crawling are also more important.

• Maintain stable and loose frequency conversion tracking.

• The edm hole drilling machine should re-perforate or perforate multiple times with an appropriate amount. In the case of a small amount, sweep the perforated surface once, which will have a beneficial effect on dimensional accuracy and smoothness. Continuous sweeping three times will reverse the stripes. Basically, as long as the repeated positioning accuracy of the machine tool is high, the finish of the perforated surface of Sammlite Machinery Drill EDM Factory’s edm hole drilling machine will be improved by one to two orders of magnitude, and it will not take too much time.
