What is the main purpose of cnc processing?

In the era we live in, the efficiency of many different machines instead of manual work to complete this kind of work will be greatly improved, so let's now take a look at what is the main purpose of cnc processing?

 

1. Cnc machining is responsible for the operation, cnc machining maintenance and daily maintenance of the machining center machine tool, and is familiar with the performance and basic structure of the machining Shop center group machine tool;

 

2. The cnc processing is subject to the production arrangement for product trial production and mass production, and the products are processed according to the requirements of the drawings to ensure product quality;

 

3. Cnc machining process can understand the drawings and related process technical documents, assist in the analysis, processing and resolution of quality problems, and propose improvement plans;

 

4. The cnc processing department actively cooperated with the quality inspection department, and notified its supervisor in time if the quantity was found to be inaccurate, and the FQA inspection department would proofread it;

 

5. The cnc processing and technical departments coordinate to deal with Technical application problems, actively provide relevant plans, and deal with on-site problems in a timely manner;

 

6. For cnc processing, fill in the documents and materials of the processing center machine tools and products as required, and make production operation records and cnc processing equipment maintenance records;

 

7. The cnc process Introduction completes other quality management system work and actively assists in the completion of the work of related departments; completes other tasks assigned by the superior.

 

Extended information:

 

Compared with ordinary machine tools, CNC machine tools have the following characteristics:

 

High processing precision and stable processing quality;

 

Multi-coordinate linkage can be carried out, and Autometal parts with complex shapes can be processed;

 

When Tailored machining parts are changed, generally only the NC program needs to be changed, which can save production preparation time;

 

The machine tool itself has high precision, large CNC sheet metal machining rigidity, can choose a favorable processing amount, and high productivity (generally 3~5 times of ordinary machine tools);

 

The machine tool has a high degree of automation, which can reduce labor intensity;

 

The requirements for the quality of the operators are higher, and the technical requirements for the maintenance personnel are higher.

 

working principle

 

CNC machine tools generally consist of the following Building parts:

 

The host, which is the main body of the CNC machine tool, includes the machine body, CNC machining column, CNC machining spindle, CNC machining feed mechanism and other mechanical components. It is a Medical parts used to complete various cutting processes.

 

The numerical control device is the core of the numerical control machine tool, including hardware (printed circuit board, cnc processing CRT display, cnc processing key box, cnc processing paper tape reader, etc.) and corresponding software for inputting Prototype parts programs and completing the input Information storage, cnc processing data conversion, cnc processing interpolation calculation and realization of various control functions.

 

The driving device, which is the driving part of the CNC machine tool actuator, includes a spindle drive unit, a cnc processing feed unit, a cnc processing spindle motor and a feed motor, etc. It realizes the spindle and feed drive through the electric or Electronic parts servo system under the control of the numerical co

 

 

ntrol device. When several feeds are linked, it can complete positioning, cnc processing straight line, cnc processing plane curve and space curve processing.

 

Auxiliary devices, some necessary supporting Mobile parts

 

 

 

 

of index-controlled machine tools to ensure the operation of CNC machine tools, such as cooling, CNC machining chip removal, CNC machining lubrication, CNC machining lighting, CNC machining monitoring, etc. It includes hydraulic and pneumatic devices, cnc machining chip removal device, cnc machining exchange table, cnc alloy machining CNC turntable and CNC indexing head, as well as cutting tools and monitoring and testing devices.

 

Programming and other ancillary equipment can be used to program aluminum parts, cnc processing and storage, etc. outside the machine.

 

use

 

Numerical control CNC Lathing are mainly used for large-scale machining of parts, and their processing methods include turning outer circle, boring, turning plane and so on. Programs can be written, suitable for mass production, and the production process has a high degree of automation.

 

Since the Massachusetts Institute of Technology developed the world's first CNC machine tool in 1952, CNC machine tools have been widely used in the manufacturing industries, especially in automobiles, CNC processing, aerospace, CNC processing, and military industries. Both hardware and software have developed rapidly.

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.
