Before installing the spark machine, check whether there are these potential factors in the area

 EDM is a kind of mechanical equipment used for processing. It is mostly suitable for the processing and production of other special materials such as metal and machinery. 

EDM is mainly through two methods of discharge and electro-erosion treatment, using two-level pulse and electric erosion produced by discharge To remove the island electricity material.

Please pay attention to the following matters before installing the mirror spark machine:

  • 1. In order to ensure the accuracy of the spark machine, the allowable ground vibration is 40 decibels. When the vibration exceeds this range, it is necessary to excite the anti-vibration or vibration machine to a smaller place for the infrastructure project.
  • 2. The spark machine should be placed in a place with less dust because the grinder, sandblasting machine and other equipment will produce metal particle dust, which is easy to accumulate on the circuit board and cause machine tool failure. The metal particle dust can also easily cause the spark machine screw and guide rail to wear.
  • 3. The operating environment temperature should be controlled between 15-30°, and the humidity should not be higher than 75%. Finishing should try to ensure a constant temperature, and humidity is generally maintained at about 50%. In the absence of air conditioning, direct sunlight and air blowing should also be avoided.
  • 4. When the spark machine is placed in an environment without acid and other chemically corrosive gases, the harsh gas environment will have a certain impact on the transmission mechanism of the machine tool.
  • 5. Three-phase power supply 380V±10%, no neutral; grounding resistance <1Ω; and current protection power switch should not be shared with other equipment.
  • 6. The installation site of spark machine tools should be equipped with fire safety equipment.
  • 7. Electromagnetic interference may occur in the electrical processing system. Keep away from TV and radio as much as possible.

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.
