Three automatic processing methods of EDM

 The use of EDM can be processed faster and with high accuracy. Automation equipment is also its unique highlight, but how to realize the automation of EDM? 

There are several ways? Let me introduce you.

  • 1. Automatic tool change device. The acquisition of a simple tool changer requires only increased cost, but it can continue until all electrodes on the turntable are used.
  • 2. Although the cost of purchasing EDM is slightly higher, the return is higher. The ordinary one can only carry 10-20 chucks, while the EDM machine can operate about 50 chucks. The ordinary number comes from the design of the equipment, while the latter is different.
  • 3. The electric spark can automatically change the guiding device. However, if two or more different types of electrodes are required to process the workpiece, this automation is particularly important, because different types of electrodes require different guide rails to match different diameter sizes. More importantly, the work that the operator needs to do can now be done through the tool converter, which can free the operator to do more valuable and high-value-added work, making the entire process more valuable. The important thing here is not that more time is needed, because this system can make workers more efficient.

The design of EDM is numerically controlled or computer controlled, and the operation is very simple. Some processing plants are still shy to talk about automation, or because of fear of the technology itself, others worry that if two machine tools are turned off at the same time, the whole process is likely to be interrupted. 

This kind of downtime is a hidden danger for many factories, especially those that want to keep up with the demands of customers in the current industry and supply them in time. However, we will avoid this form of shutdown, and there is no need to turn to a process engineer or engineering company to automate the process, and you only need to cooperate with the EDM machine tool or machine supplier to adjust a set of programs based on the operation of the EDM machine tool.

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.
