Six advantages of mirror spark machine

 Mirror spark machining is a very important equipment in the mold manufacturing industry. 

Each mold cannot be processed without its processing at the factory, and the mirror spark machine has an unshakable position in the mold manufacturing industry. 

Today I will tell you about it. Some advantages of mirror spark machine.

  • 1. There are two side repair procedures for mirror spark machine. The rectangular corner is a flat side restoration plan, and the round or multi-face ellipse uses a flat bottom side restoration plan. During the side repair process, the electrode moves toward the workpiece at a certain angle. At this time, the tool electrode moves from the middle to the outside, from top to bottom at the same time, and is automatically controlled by CNC, that is, the three-axis connecting rod. This type of movement is not easy to deposit carbon, easy to exhaust and exhaust, does not produce arcs, and has high production efficiency.
  • 2. The X-axis horizontal machining of the mirror spark machine has a high precision of closing the mold, and the productivity can be much higher than that of the Z-axis machining.
  • 3. The electrode can be used for rough and fine machining with a CNC EDM, which saves the manufacturing time and cost of the double electrode, saves the trouble caused by the correction of the fine machining electrode, and shortens the mold manufacturing time.
  • 4. The EDM machine tool adds special control to the control circuit. When an arc or false short circuit occurs, immediately cut off the pulse power supply and stop supplying power to the cavity. The electrode temperature will not continue to rise and the fire will be reduced.
  • 5. EDM adopts complete low-voltage pulse mode after high-voltage breakdown, with the same pulse width. Practice has proved that this pulse mode further reduces the wear of the tool electrode, the roughness and uniformity of the machined surface, and the wear of the tool electrode is very small.
  • 6. The self-appropriate function, that is, the self-appropriate lifting knife, is that when the discharge is more stable than the generated discharge, the cavity is not corroded and cleaned. When the discharge is greater than the discharge, the shape cavity is not etched, that is When the balance is broken and the balance or discharge is greater than the production, the lifting knife stops and the efficiency is improved.

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.
