CNC Parts Selection To Ensure Durability In The Material

Zhong Bang and Intermac CNC parts have various applications in the industries. All CNC machines follow the same general steps to produce parts with the only difference in the application of the required parts. Therefore, it is necessary to analyze the environment where you will employ the CNC parts. For instance, if an environment is susceptible to corrosion and you choose mild steel for manufacturing, your product will degrade in no time. Therefore, the correct selection of parts in CNC is extremely crucial to provide durability to the manufactured product.

This article provides complete detail of the parts and materials that will help you figure out what parts you need to CNC machine your products.

Introduction To Zhong Bang and Intermac CNC Parts And Machining

CNC machining has become the most dominant manufacturing technique in today’s world. This technique ensures the highest accuracy in its manufactured parts. Therefore, Zhong Bang and intermac CNC parts find extensive use in major industries like aerospace, defense, military, and medical. These industries require parts with maximum precision and no other technique provides accuracy in its parts like CNC. CNC works on the principles of robotics and performs all the operations with automation. It involves the least human intervention hence reduced the chances of error and defects in the Zhong Bang and intermac CNC parts.

CNC is a subtractive manufacturing technique that involves the removal of material in the form of chips. This automation makes it distinctive from the 3D printing and injection molding that requires material addition to fabricate final products. The cutting tool rotates over the material in multiple axes and hence removes the material.

Working Principle Behind The CNC parts

CNC manufactures interface CNC parts on CAM/CAD basis. Computer-aided manufacturing brings automation to the process and contains the design requirements provided by the clients. The CAD interprets the requirements and converts the information to G-code which is the machine language understood by CNC. The CAD operates the CNC and instructs the machine regarding its movement, speed, and rotation of the cutting tool. Hence, the cutting tool runs over the workpiece and with the instructions provided by the computer, separates the final product.

The Zhong Bang CNC parts do not require human intervention. The operation is completely automatic and produces several parts in a short duration. The major CNC tools include milling, turning, and drilling and each of them has its specifications and applications. However, one does not need to change the entire equipment to perform several operations as a single CNC machine is enough to perform all the operations.

General Rules To Select CNC Parts

CNC machining is capable of producing parts with several different materials like metals, plastic, etc. With its widespread accessibility, it becomes difficult to select the right  CNC parts that your product will need. The difference in specifications, applications, and properties can make it difficult for the manufacturer to select the right  CNC parts. Here we will discuss the general steps to follow while selecting CNC parts.

Requirements Of The Final Product

Before you start selecting the Zhong Bang and  intermac CNC parts, analyze the requirements of the final workpiece. For instance, consider the environments where you will be using the parts and the stresses it will have to bear. The mechanical stresses include the polishing and grinding of the final material. Therefore, you should analyze if your part will be able to bear the stresses. The thermal stresses include the heat load due to mechanical operations. Hence, you need to consider all the aspects of the environment and conditions where you will be using the parts.

Alternate Materials

It is not a good idea to arrange only the parts you think you will be needing. Candidate materials play their role in these circumstances. They have similar properties to the parts you require with different specifications. In this way, you will have better choices to decide what material will exactly suit your part.

Most Common Materials To Build  CNC Parts

The material selection to producing Zhong Bang and intermac CNC parts plays a vital role in the manufacturing. Selecting a part that will not be able to adjust to the required environment can result in financial loss. For instance, if the material you use is corrosive and you are employing the CNC part in an open atmosphere, then all your efforts and money will go in vain. Therefore, selecting the right material will help you save time and money.


CNC machining extensively uses Aluminium due to its great electrical and thermal conductivity. It is one of the most economical materials and is therefore highly preferred for prototype making and design. The metal has adequate machinability and can bear stresses with its great tensile strength. One of its alloy 6082 is one of the most widely used alloys. Another aluminum alloy i.e. Aluminium 7975 can bear extreme stresses in the aerospace sector with its high tensile strength compared to steel.

Aluminum 5083 shows excellent resistance to seawater conditions and therefore can be CNC machined to produce marine parts.

Stainless Steel Parts

Stainless Steel is one of the most common alloys that finds extensive use in industries. It shows excellent resistance to corrosion and extremely ductile i.e. can spread into sheets. One can perform several operations including welding, polishing, machining, etc with great convenience on stainless steel. Stainless Steel 304 shows the highest resistance to corrosion in most environments. On the other hand, stainless Steel 316 finds extensive use in harsh saline environments like seawater.

CNC machining on another alloy i.e. Stainless Steel 2205 duplex can make parts that will resist high-pressure effects in the Oil and Gas sector. If you want to make CNC Intermac Parts for turbines, you can choose stainless Steel 17-4.

Mild Steel

If you think the environment where you will employ the CNC part is not corrosive, you can employ mild steel as it will save you cost. The most common mild steel alloy is 1018 that shows great strength to machinability, toughness, and hardness. For industrial and construction purposes, you can use mild steel A36.


Other than metals, one can machine several plastics on the CNC. CNC machining uses plastics as they have low density and are lightweight. The ABS plastic finds extensive use for prototyping injection molding.

Nylon is another key material that shows high resistance to chemical abrasion and has excellent mechanical properties.

Polycarbonate is another form of plastic that shows better properties in contrast to ABS. The Delrin shows high machinability among all the plastics. It shows excellent stiffness and precision and can withstand high temperatures.

Other materials that can be CNC machined include Teflon. It shows excellent resistance to high temperatures. High-density polyethylene is another lightweight plastic. CNC techniques use HDPE to manufacture piping systems.

When you select plastics as materials for your CNC always make sure that it is preferable to use plastic only in lightweight applications. When you want to CNC machine apart for a harsh environment i.e. Hardness, high-resistance, temperature, etc, use metals. Most plastics are famous as they are ideal for prototyping.


To sum up, the CNC parts differ in manufacturing as their application depends on the environment where they would be employed. However, the generic steps remain the same. Therefore, as discussed in the article one needs to analyze the properties of the parts according to the specifications and applications of the final product.
