Fourteen advantages of mirror spark machine when working

 The mirror spark machine has such a abbreviation as "specializing in all kinds of difficult and complicated tools." 

This sentence proves that this spark machine is not better than the spark machine, because its different structure makes its processing method different, and it can process a variety of difficult For molds, especially some molds that need to be polished, the mirror spark machine can directly save this step, which is also one of its advantages.

  • 1. Mirror EDM can realize the vertical angle of the workpiece, which cannot be realized by grinding, and the grinding must have an R angle;
  • 2. There is no great cutting force, so the machine is smaller in size and lighter in weight, and there is no need to install it on the basis;
  • 3. Any material can be processed, like some hard, soft and high melting point materials;
  • 4. Electrical machining does not require cutting force, the processed material will not be deformed, and the machining accuracy is guaranteed;
  • 5. Reduce the influence of small heat during processing, reduce the heat-affected layer and the quality of the workpiece after high processing;
  • 6. An electrical discharge machining tool whose electrodeless material is harder than the workpiece material, and the tool electrode is easy to manufacture;
  • 7. EDM can process high hardness workpieces. Generally speaking, harder objects are processed with hard tools, and harder workpieces are processed with soft electrodes;
  • 8. EDM is a non-contact machining, the tool electrode is not in contact with the workpiece, and compared with other machining methods, it will not cause hard damage to the workpiece;
  • 9. The loss of mirror spark machine is small;
  • 10. It saves labor costs and does not need to save time and process mold polishing to reduce personnel and improve efficiency;
  • 11. Save material cost, only use one electrode;
  • 12. The processing effect is good, the spindle lifting tool speed is greater than 6M/Min;
  • 13. The price of external processing is much higher than that of ordinary spark machines;
  • 14. Advanced detection technology.

PTJ RFQ

What Is PTJ?
PTJ adopts flexible manufacturing methods to help our customers to control the product cost but best quality guranteed. Some frequently used machining processes include CNC milling, CNC turning, precision grinding, EDM machining, laser cutting, welding, CNC punching, sheet metal stamping, profile extrusion, die casting, forging, and more. Most of the custom precision cnc machining china parts and plastic machining components we made are related to automation machines, robotics, medical devices, fiber optics, aerospace/aircraft, test and measurement, sensors, telecom components, scientific devices, audio equipments, bicycles, boats, camera, cars, drones, electronic enclosures, front panels, furniture and architecture hardware, lighting, motorcycles, scooters, utv, jeeps, trucks, sports equipments, machinery, music instruments, and so on.
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.
