CNC machining parts for production emphasized precision, the elimination of internal waste, and the improvement of product quality and throughput, to enhance both the profit margin and customer satisfaction.  The market offers a diverse range of CNC machining products to meet different requirements.


Different Types of CNC Production Machining

CNC machining offers various options and CNC products to meet different production needs. Let's explore the different types and their features.


  • Low Volume CNC Machining

Low volume CNC machining refers to a CNC machining service that focuses on manufacturing small quantities of fully fabricated parts within a restricted range. Generally, this range is approximately 50 to 1000 pieces.

Currently, low volume CNC machining, also known as small-batch CNC machining, has gained popularity for several reasons:

  • It fills the gap between the production scales of prototypes and initial predictions.

  • It leads to cost reduction.

  • It enhances access to nascent markets.

  • It is highly suitable for products with short life cycles.

  • It simplifies the process of design modification.


  • High Volume CNC Machining

High volume CNC machining is employed for the mass production of substantial quantities of materials (exceeding 1000 parts) while ensuring the quality remains up to standard. It is the preferred process for numerous industries as they can obtain a large number of parts at a lower cost.

High volume CNC machining, also referred to as large-scale CNC machining, is in demand due to reduced labor requirements and lower prices.


  • Custom or Prototype CNC Machining

Custom or prototype CNC machining is commonly utilized in smaller quantities during the stage of new product development (NPD). The emergence of new CNC machining and custom manufacturing technologies has allowed customers to take advantage of CNC machining for prototyping. This implies that CNC-machined prototypes can be created earlier in the design process, offering functional prototypes that possess the same appearance, sensation, and functionality as the ultimate product.

Furthermore, CNC machining is a favored option for custom part manufacturing. The same contemporary advancements that render CNC machining a suitable choice for prototyping also make it a good fit for custom part manufacturing. CNC machining proves to be a cost-effective alternative for custom and prototype machined parts.


Benefits of Production Machining

  • Enhanced Production and Minimized Wastage

As both CNC production machining and CNC machine products rely more on machines and less on humans, there is greater production efficiency. For instance, an automated operation and comprehensive work guarantee higher efficiency. Additionally, due to advancements in the utilized software, the wastage of materials is minimized.

  • Reduced Labor Requirements

Both high and low volume CNC machining do not demand a significant amount of labor. This leads to a decrease in the expenditure on labor. Nevertheless, although this does not imply the complete elimination of labor, skilled employees are necessary to supervise each operation in every production process.

  • Increased Profitability

CNC machining is a production process that requires minimal monitoring. This is an attribute that both processes share. They both leverage the advantages of CNC machining to boost profits. There is a reduction in manual labor and costs due to the competitive pricing of the parts. However, high volume CNC machining experiences a more substantial increase because of the larger production scale.

Must Know Points for Outsourcing Production CNC Machining

Before outsourcing your project to a company similar to ours, there are several crucial aspects you should be familiar with. Here are three key elements that will equip you for the necessary operations in CNC manufacturing.


1. Design and Material Optimization

Obtaining an optimal design typically stems from comprehending how to effectively optimize the design of the available materials. The following are some tips on optimizing your parts design based on material properties:

  • Simplify the Design

Simplifying the part's CAD file during the design phase can assist you in circumventing unnecessary machining procedures. Optimization can also curtail the operation time and eliminate other drawbacks. Unnecessary components may result in additional machining, and it is advisable to eliminate them.

  • Select the Appropriate Wall Thickness

The parts you are fabricating will be subjected to pressure from the CNC machining tools. Hence, choosing the correct wall thickness for the parts is of paramount importance. It should neither be too thin as it could break easily, nor too thick as this might lead to tool hanging, deflection, and fracture.

  • Steer Clear of Small and Complex Text and Features

If your project demands markings and text, it is preferable to avoid using small ones. This is due to the increase in cost and the complexity involved in the machine's operation. Instead, opt for larger text or markings.

  • Employ Standard Hole Size

When drilling is necessary, it is better to utilize a standard hole size for seamless operations. This will save you time while guaranteeing high precision and accuracy.


2. Standard Production Process

Understanding the standard production processes utilized in CNC machining is manageable. To facilitate better comprehension, we have categorized the process of CNC production machining into four steps as elaborated below:

  • Design a CAD Model

The initial task is to create a CAD file. CAD files (Computer-Aided Design) can be in either 2D or 3D formats and can be achieved using CAD software. This software enables you to depict each part of the prospective product with the most precise technical specifications. During this process, it is essential to bear in mind that your workpiece significantly influences the feasibility of the design. Further details regarding this will be provided under the materials necessary for CNC production machining.

  • Convert the CAD File to a CNC Program

After designing the CAD file, the subsequent step is to input it into CNC software. The software's function is to analyze the CAD file to obtain the necessary programming codes required to run the operation.

In CNC machining, there are two types of codes. The G-code (Geometric code) operates geometrically, meaning it governs the machine's actions such as its movement, timing, and path. Conversely, the M-code is responsible for factors that control the CNC machine.

  • Setting up the CNC Machine

Preparing the CNC machine for the process constitutes setting it up. The configuration depends on whether you are employing a high or low-volume process. This encompasses various machines like the turning machine, milling machine, grinding machine, etc., utilized in the process. Moreover, any proficient company involved in CNC production machining must have a competent and skilled engineer overseeing the process.

  • Execute the Operation

After ensuring everything is in order and accordance with the plan, you can commence the operation. Once the program is initiated, it will control all the actions of the CNC machine and guide it to achieve the desired outcome.


3. Quantity and Lead Time

Another matter of significant concern in CNC manufacturing is the quantity and lead time. Most contemporary CNC machining companies can handle both low and high volume CNC machining. Nevertheless, the lead time is contingent upon the sophistication of the software, the updatedness of their machinery, and their operational capacity.

Achieving the best in terms of quantity and quality within a reasonable lead time involves understanding the process and identifying the company capable of providing it.
