How to choose the right CNC machining material？
The materials are wrong, all in vain! In order to produce satisfactory products, the choice of materials is the most basic step and the most critical step. CNC machining can choose a lot of materials, including metal materials, non-metallic materials and composite materials.
Common metal materials include steel, aluminum alloy, copper alloy, stainless steel and so on. Non-metallic materials are engineering plastics, nylon, bakelite, epoxy resin and so on. Composite materials are fiber reinforced plastic, carbon fiber reinforced epoxy resin, glass fiber reinforced aluminum and so on.
Different materials have different physical and mechanical properties, and the correct selection of the right material is critical to the performance, accuracy and durability of the part. Starting from my own experience, this article will share with you how to choose low cost and suitable materials among many processing materials.
First, we need to determine the end use of the product and its parts. For example, medical equipment needs to be disinfected, lunch boxes need to be heated in the microwave oven, bearings, gears, etc., need to be used for load-bearing and multiple rotational friction.
After determining the use, starting from the actual application needs of the product, the use of the product is investigated, and its technical requirements and environmental requirements are analyzed, and these needs are transformed into the characteristics of the material. For example, parts of medical equipment may have to withstand the extreme heat of an autoclave; Bearings, gears and other materials have requirements for wear resistance, tensile strength and compressive strength. Mainly can be analyzed from the following points:
01 Environmental Requirements
Analyze the actual use scenario and environment of the product; For example: What is the long-term working temperature of the product, the highest/lowest working temperature, respectively, belonging to high temperature or low temperature? Are there UV protection requirements indoors or outdoors? Is it in a dry environment or a humid, corrosive environment? Etc.
02 Technical Requirements
According to the technical requirements of the product, the required capabilities are analyzed, which can cover a range of application-related factors. Such as: the product needs to have conductive, insulating or anti-static which of the capabilities? Is heat dissipation, thermal conductivity, or flame retardant required? Do you need exposure to chemical solvents? Etc.
03 Physical Performance requirements
Analyze the required physical properties of the part based on the intended use of the product and the environment in which it will be used. For parts subjected to high stress or wear, factors such as strength, toughness and wear resistance are critical; For parts exposed to high temperatures for a long time, good thermal stability is required.
04 Appearance and surface treatment requirements
The market acceptance of the product depends largely on the appearance, the color and transparency of different materials are different, the finish and the corresponding surface treatment are also different. Therefore, according to the aesthetic requirements of the product, the processing materials should be selected.
05 Processing performance considerations
The machining properties of the material will affect the manufacturing process and accuracy of the part. For example, although stainless steel is rust resistant and corrosion resistant, its hardness is high, and it is easy to wear the tool during processing, resulting in very high processing costs, and it is not a good material to process. The plastic hardness is low, but it is easy to soften and deform during the heating process, and the stability is poor, which needs to be selected according to actual needs.
Because the actual application requirements of the product are composed of a number of contents, there may be multiple materials that meet the application requirements of a product; Or the situation where the optimal selection of different application requirements corresponds to different materials; We may end up with several materials that meet our specific requirements. Therefore, once the desired material properties are clearly defined, the remaining selection step is to search for the material that best matches those properties.
The selection of candidate materials begins with a review of material properties data, of course, it is not possible to investigate thousands of applied materials, and there is no need to do so. We can start from the material category, and first decide whether we need metal materials, non-metallic materials or composite materials. Then the previous analysis results, corresponding to the material characteristics, narrow the selection of candidate materials. Finally, the material cost information is used to select the most suitable material for the product from a number of candidate materials.
At present, Honscn has selected and launched a number of materials suitable for processing, which have been a popular choice for our customers.
Introduction to the properties of metal materials
Metallic materials refer to materials with properties such as luster, ductility, easy conduction and heat transfer. Its performance is mainly divided into four aspects, namely: mechanical properties, chemical properties, physical properties, process properties. These properties determine the scope of application of the material and the rationality of the application, which is an important reference for us to choose metal materials.The following will introduce two types of metal materials, aluminum alloy and copper alloy, which have different mechanical properties and processing characteristics.
There are more than 1000 aluminum alloy grades registered in the world, each brand name and meaning are different, different grades of aluminum alloy in hardness, strength, processability, decoration, corrosion resistance, weldability and other mechanical properties and chemical properties there are obvious differences, each has its strengths and weaknesses.
hardness
Hardness refers to its ability to resist scratches or indentations. It has a direct relationship with the chemical composition of the alloy, and different states have different effects on the hardness of aluminum. The hardness directly affects the cutting speed and the type of tool material that can be used in CNC machining.
From the highest hardness that can be achieved, 7 series > 2 series > 6 series > 5 series > 3 series > 1 series.
intensity
Strength refers to its ability to resist deformation and fracture, commonly used indicators include yield strength, tensile strength and so on.
It is an important factor that must be considered in product design, especially when aluminum alloy components are used as structural parts, the appropriate alloy should be selected according to the pressure under.
There is a positive relationship between hardness and strength: the strength of pure aluminum is the lowest, and the strength of 2 series and 7 series heat-treated alloys is the highest.
density
Density refers to its mass per unit volume and is often used to calculate the weight of a material.
Density is an important factor for a variety of different applications. Depending on the application, the density of aluminum will have a significant impact on how it is used. For example, lightweight, high-strength aluminum is ideal for construction and industrial applications.
The density of aluminum is about 2700kg/m³, and the density value of different types of aluminum alloy does not change much.
Corrosion resistance
Corrosion resistance refers to its ability to resist corrosion when in contact with other substances. It includes chemical corrosion resistance, electrochemical corrosion resistance, stress corrosion resistance and other properties.
Corrosion resistance selection principle should be based on its use occasion, high-strength alloy used in a corrosive environment, must use a variety of anti-corrosion composite materials.
In general, the corrosion resistance of series 1 pure aluminum is the best, series 5 performs well, followed by series 3 and 6, and series 2 and 7 are poor.
processability
The machinability includes formability and machinability. Because formability is related to the state, after selecting the grade of aluminum alloy, it is also necessary to consider the strength range of each state, usually high strength materials are not easy to form.
If the aluminum is to be bent, drawn, deep drawing and other forming processes, the formability of the fully annealed material is the best, and on the contrary, the formability of the heat-treated material is the worst.
The machinability of aluminum alloy has a great relationship with the alloy composition, usually higher strength aluminum alloy machinability is better, on the contrary, low strength machinability is poor.
For molds, mechanical parts and other products that need to be cut, the machinability of aluminum alloy is an important consideration.
Welding and bending properties
Most aluminum alloys are welded without problems. In particular, some 5 series aluminum alloys are specially designed for welding considerations; Relatively speaking, some 2 series and 7 series aluminum alloys are more difficult to weld.
In addition, the 5 series aluminum alloy is also the most suitable for bending a class of aluminum alloy products.
Decorative property
When aluminum is applied to decoration or some specific occasions, its surface needs to be processed to obtain the corresponding color and surface organization. This situation requires us to focus on the decorative properties of materials.
Aluminum surface treatment options include anodizing and spraying. In general, materials with good corrosion resistance have excellent surface treatment properties.
Other characteristics
In addition to the above characteristics, there are electrical conductivity, wear resistance, heat resistance and other properties, we need to consider more in the selection of materials.
Orichalcum
Brass is an alloy of copper and zinc. Brass with different mechanical properties can be obtained by changing the content of zinc in brass. The higher the content of zinc in brass, the higher its strength and slightly lower plasticity.
The zinc content of the brass used in the industry does not exceed 45%, and the zinc content will be brittle and make the alloy performance worse. Adding 1% tin to brass can significantly improve the resistance of brass to seawater and Marine atmosphere corrosion, so it is called "navy brass".
Tin can improve the machinability of brass. Lead brass is commonly referred to as easy to cut national standard copper. The main purpose of adding lead is to improve the machinability and wear resistance, and lead has little effect on the strength of brass. Carving copper is also a kind of lead brass.
Most brasses have good color, processability, ductility, and are easy to electroplate or paint.
Red copper
Copper is pure copper, also known as red copper, has good electrical and thermal conductivity, excellent plasticity, easy hot pressing and cold pressure processing, can be made into plates, rods, tubes, wires, strips, foil and other copper.
A large number of products that require good electrical conductivity such as electrocorroded copper and conductive bars for the manufacture of EDM, magnetic instruments and instruments that must be resistant to magnetic interference, such as compass and aviation instruments.
No matter what kind of material, a single model basically can not meet all the performance requirements of a product at the same time, and it is not necessary. We should set the priority of various performance according to the performance requirements of the product, the use of the environment, the processing process and other factors, reasonable selection of materials, and reasonable control of costs under the premise of ensuring performance.

Why CNC machining stands out?
Previous machines which were known as numerical control machines (NC) located their positions via G-codes. These G-codes were manipulated manually by the user unlike in CNC machining whereby this task is computerized. In the most recent versions known as the parametric program, logical commands have been fixed in a manner that they can work together with these G-codes. This modified version allows users to regulate and manipulate system parameters effortlessly.
Benefits of using CNC machines:
The improvement in technology used in the manufacturing of these machines has brought about a number of benefits.
These include the following:
- There is improved speed, accuracy, productivity and efficiency of tasks - They significantly reduce the incidents of accidents since computerized systems minimize the contact between the tools and the user. This makes the metalworking process a more comfortable undertaking.
CNC Milling Machines:
CNC milling machines function by using a computerized system to transmit signals to a stepper motor controller. This system instructs the stepper motor on the direction to follow and the number of steps it is supposed to take. The motor is linked to the drive mechanism of the mill in the X, Y and Z axes. Some CNC milling machines are known to utilize a servo motor as a replacement for the stepper motor. They have below mentioned advantages:
- Metals can be cut at higher rates - Servo motors have a feedback loop which enables the machine to accurately resume to its initial position.
How to find the best CNC milling machines?
These machines have become essential in very many facets of life especially in the running of our businesses. The purchasing of this machines entail that you have to find the right kind of supplier or dealer. The following are tips to assist you in identifying the most ideal place where the machines can be obtained from:
- Check the quality of the milling machine. Visit online forums to get information on the available brands in the market and the most reliable brands according to customer reviews.
- Choose a supplier or dealer with professional staff and highly skilled personnel to repair your milling machine if it breaks down - If you are looking for a cost cutting option, some suppliers deal with second hand milling machines so, pursue such options.
Maintaining your CNC milling machine:
Once you have your milling machine purchased, some important tips can be followed to keep it in top condition. These machines are usually maintained by a set up process. This includes the below procedures:
- Wipe the table to the T-holder to keep it free it from fragments and rust.
- Place its vise down and tighten it with bolts. Straighten the vices using an indicator - Place every tool into collects and ensure they are safely locked.
- Set the collets into the changer of the tool as per to the manual of the machine.
- Confirm if the machine "knows" where it ought to stop. This is to guarantee that the machine makes an accurate cut. - Set the spindle on the zero point then ignite the machine again on the X and Y axes - Next, locate the Z point by lowering the spindle to the top of material. This point will be used as a reference in cutting other materials.
This simple setting up process guarantees that the CNC machining machine works efficiently for years on end. This process is to be repeated whenever the machine is heavily used.
Yesterday, the share prices of SKP and Tecnic climbed to all-time highs of 71 sen and RM5.08, respectively, before both stocks were suspended, "pending a material announcement".
It is learnt that the merger and acquisition exercise could involve cash and the issuance of new SKP shares.
Gan and his family own about 67% in SKP and 69% in Tecnic, formerly known as STS Tecnic Bhd.
"It's a move that the Gan family has been looking at for some time to create an entity with economies of scale. A merger can be synergistic for the two companies, which can lead to accretive earnings going forward," said a source.
SKP, which has been on expansion mode over the past few years, is in the business of manufacturing plastic parts and components, contract manufacturing, precision mould making, the sub-assembly of electronic and electrical equipment and other secondary processes.
For the financial year ended March 31, 2013 (FY13), British electrical appliance brand Dyson contributed 55% to SKP's total sales.
According to SKP's website, its other clients include Hewlett-Packard, Sharp, Flextronics and Pioneer.
Tecnic, meanwhile, is involved in plastic moulding design and fabrication, plastic injection and blow moulding for the automotive, electrical and electronic sectors as well as industrial consumable products. It counts Valeo, Sharp, Panasonic, Denso, Suzuki, Proton and Perodua as its clients.
SKP and Tecnic had cash and cash equivalents of RM19.4mil and RM25.7mil, respectively, as at June 30. However, SKP has seen a higher trading volume in recent months, while Tecnic is a relatively tightly held stock.
In an earlier note, RHB Research said SKP could achieve a two-year earnings compounded annual growth rate of 57.9% on the back of a 75% expansion in capacity to cater to increasing orders from Dyson.
SKP has a new plant in Senai, Johor, which is slated for completion next month and achieve full-scale operations by FY17, Kenanga Research said in a separate report.
The research house noted that SKP's stronger order-book, underpinned by orders from Dyson to manufacture two new product lines for vacuum cleaners and fans, will provide earnings visibility for the next few years.
"The new products are next-generation appliances that will be able to fetch higher margins and contribute to the group's earnings. We understand that a major part of the group's new plant will cater to the production of the two new products," it added.
SKP jumped 10.5 sen to 71 sen, with 38.37 million shares being traded.
Tecnic rose 31 sen, or 6.5%, to RM5.08, with 219,500 shares changing hands.
