How CNC Precision Machining Works

After activating the CNC system, the product file will be programmed into the software and assigned to the corresponding tools and machinery. These tools and machinery will perform the specified cutting tasks. The CNC machining process includes the following stages:
– Design CAD Model
– Convert CAD file to CNC program
– Prepare CNC machine and tools
– CNC Machining operations

Main Processes Of CNC Machining

– Frezare CNC: Use a multi-point rotating tool to remove material from the workpiece. Basic mills consist of a 3-axis system (X, Y and Z), which is still one of the most popular and widely used machining processes. In 3-axis machining, the workpiece remains fixed, and the rotating tool cuts along the x, y, and z axes. Meanwhile, most newer mills can accommodate two additional axis, 4-axis CNC machining and 5-axis CNC machining have higher versatility, and they are often used in the production of high-precision parts.

– Strunjire CNC: Use a single-point cutting tools to remove material from the rotating workpiece. In CNC turning, the CNC machine, typically a lathe or turning machine, feeds the cutting tool in a linear motion along the surface of the rotating workpiece, removing material around the circumference until the desired diameter is achieved. Most CNC lathes consist of two axis, X and Z.

 

Features of CNC Machining

Advantages:

Fast and Repeatable

Quick removal of large amounts of metal material,
parts ready as fast as 1 day

Precizie

High-precision tolerances ranging from +/-0.005″ –
0.01″, depending on customer specs.

Gamă largă de materiale

Choose from over 50 metal and plastic materials.

 

Drawbacks

Structure Limits

Interlocking and hollowed structure is difficult to be machined with CNC.

Scalable Volume

CNC Machining has scalable volumes for
production of 1-100,000 parts.

Custom Surface Finishes

Suitable for many different kinds of substrates,
make your parts just the same as real products.

Cost Saving

Low investment in tooling and preparation costs,
economical for parts with simple structure.

 

 

Scale Effect

The unit cost and lead time will not be reduced as much as injection molded parts.

Manufacturing Process of precision machining tech

  • Design and Programming: Begin with CAD design and CAM programming to define the part’s specifications and machining operations.
  • Material Selection and Setup: Choose the appropriate material and set up the CNC machine with the necessary tools.
  • Machining Operations: Execute the programmed instructions to cut, mill, and shape the material into the desired part.
  • Controlul calității: Conduct thorough checks during and after machining to ensure dimensional accuracy and surface quality.
  • Finisare si inspectie: Apply finishing operations as needed and perform final inspection to verify the part meets specifications before packaging and delivery.

  • Nu oferim servicii de proiectare. Sunteți responsabil pentru trimiterea desenelor CAD 2D și 3D, iar apoi vă putem oferi o revizuire Design for Manufacturing la primirea comenzii. trimite desenul tău și începe azi
  • Dacă nu aveți desene, ne puteți trimite direct mostre și vă vom ajuta să finalizați desenele.

În comparație cu alți furnizori chinezi, prețurile noastre sunt mai mici, dar nu cele mai mici. Dar oferim cele mai înalte niveluri de calitate, răspuns rapid și rezultate profesionale. și de aceea atât de mulți clienți cooperează cu noi, în comparație cu prețul, au nevoie de un partener de încredere pentru a evita pierderile grave cauzate de post-vânzare enervantă sau chiar problemele de a nu găsi pe nimeni.

  • Odată ce comanda dvs. este confirmată, vom efectua o revizuire completă a Design for Manufacturing (DFM) pentru a sublinia orice probleme despre care inginerii noștri consideră că ar putea afecta calitatea pieselor dumneavoastră.
  • Fiecare lot de mărfuri trebuie să aibă asigurarea primului articol (FAA) și apoi inspecții IPQC de mai multe ori, rapoarte de inspecție finală înainte de expediere.

Garantăm materialele și manopera noastră pe baza termenilor comenzii inițiale și a informațiilor furnizate de dumneavoastră. Orice dispută bazată pe o decizie subiectivă va fi adusă la cunoștința conducerii, care va acționa cu bună-credință pentru a vă oferi deplină satisfacție.
