The spark machine fails? How did it happen

 EDM is a kind of mold processing equipment, which is mainly suitable for testing equipment of various cables and sparks below 25mm. This equipment adopts high-voltage form, and the design is sufficiently advanced, compact and stable, but its output is stable, and the sensitivity is high enough. It is more convenient to install and use, so under what circumstances is the spark machine prone to failure?

In order to facilitate the installation and use, the DC spark machine has three structural forms: the integrated structure is compact, the sensor head, and the display controller support component as a whole, has the characteristics of compact structure and easy installation. Among them, the distributed control type is mainly used. Extrusion line, high frequency of the foam core, coaxial signal line, twisted pair line detection and other places. Split structure, where the bracket detection head is in the production line, and the display controller uses an industry standard 19-inch rack of the tray/dual desktop type, or directly to the standard configuration control cabinet to centrally control the production test line, or it can be placed on the table , But the detection head needs to be connected to the display with a dedicated cable.


Because during processing and production, the materials close to the wire products on the production line will gradually heat up. If we put the grounding cable in the electrode of high-frequency voltage for a while, the contact surface will heat up obviously, and this heat can help break down the wire. Where the insulation is thin, otherwise the wire will pass through the research electrode without being detected. The result analysis will cause the subsequent spark test and high voltage insulation performance test data to be invalid.

For Surface Finishes
Thanks to our mature supplier management and continuously experience accumulation. Now we have very stable surface finish suppliers to assist us to do different surface finishes with stable and excellent quality. Some Frequently used surface finishes are Anodizing, Oxide, Nickel Plating, Chrome Plating, Gold / Silver Plating, Powder Coating, Zinc Plating, PVD Coating, Passivation, Heat Treatment, Electrochemical machining, Brushing, Polishing, Sandblasting, etc.
General Tolerance of Equipments
1. CNC Milling tolerance: +/-0.01mm
2. CNC turning tolerance: +/-0.01mm
3. Precision grinding tolerance: +/-0.005mm
4. EDM machining tolerance: +/-0.005mm
How to Control Quality?
1. Inspection by machinist himself who is responsible for a specific part machining.
2. First article part inspection by QA.
3. IPQC patrol inspection during production.
4. PQC inspection before shipping according to ISO9001 sampling inspection standard for large quantity production. And for small quantity, 100% full inspection.
5. Material Certificates and outgoing inspection reports could be provided.
Our CNC machine and swiss machining shop sets full and advanced inspection instruments such as CMM, projector, height instrument, industrial microscope, micrometer, calipers, thread gauges, pin gauges, block gauges, etc. so as to inspect all details on drawings and confirm quality is good and issue the ourgoing reports accordingly.
How to Start Working with Our Company?
1) Sending detailed RFQ with 2D and 3D drawings to through email to info@pintejin.com. General drawing formats like PDF/ STEP/IGES/X_T etc are accepted.
2) We check and confirm about materials, surface finish and quantiy, and evaluate. If any question, our sales engineer would double check with customers until everything is clear. We will quote accordingly if we are ok to make the parts with best quality. If no question and everything is clear, we send quotation with best prices within 24 hours. Our sales engineer team is online for 7/24 for offering customers the best cnc machining services.
3) We recommend to start from few pcs prototypes for approval at the beginning. If nothing wrong after customer’s test and approval, then we proceed to volume cnc manufacturing.
Some Tips for Customers
a. We accept Paypal payment of small amount payment for samples or small batch orders for building mutual trust at the beginning. General payment terms is 30% by wire transfer, and balance before shipping.
b. Delivery time for few pcs samples are generally 5 to 7 days, and 15 to 25 days for volume production. If the order quantity was too big, we would check and confirm delivery time sepertely.
c. Our company has concrete promise to all customers that if any quality problem caused by our factory, we would remake all parts for free or send money back.
Safe Packing Methods to Prevent Goods from Damage during Transportation
Due to long distance transportation to overseas countries, safe and strong packing is very important to gurantee the parts to be in good conditions when arriving at customer’s hand. We choose different packing materials according to different parts and quantity. Some commonly used packing materials are pp/bubble bag, oil paper, foam, blister tray, 5 layer carton, wood box, etc. See below some packing pictures.
