CNC Machining FAQs
1. What is CNC Machining?

CNC (Computer Numerical Control) Machining is a subtractive manufacturing method, which adopts computerized devices to remove the extra materials from the blank and complete required tasks with CNC machine tools, to produce the final designed CNC machining parts. The machine tool, blade material, speed and feed, blade angle, cutting parameters, coolant, workpiece material, and more factors will affect the quality of the CNC machining service.

2. How does CNC Machining work?

The CNC machining process generates the final part through the subtraction of material. CNC machines are run by digital computers that control the movement of the equipment. The process of CNC machining will go through:

- Load the CAD (Computer Aided Design) file into CAM (Computer Aided Manufacturing) software.

- Determine tool paths based on the part geometry.

- CAM software creates digital instructions or G-Code tells the machine what to do and how to do it.

- CNC machines execute the operations as the programming language.

3. What’s the difference between CNC machining and conventional machining?

- Cost. Conventional machining is often less expensive, more cost-effective, and more efficient for smaller jobs. CNC machining is more expensive for little work, but it is more efficient and cost-effective for larger jobs.

- Production. The final conventionally machined product's quality is mostly determined by the machine technician's or operator's skills and talents. Geometry is encoded into the software in CNC machining, reducing the risk of human error in the quality equation.

- Repeatability. Because it is impossible to guarantee a high level of part consistency due to the human factor, traditional machining is best suited for short production runs or a single unit. Because machines are controlled by computer commands, it is simple to create similar parts or components, making CNC machining ideal for the mass production of exceedingly consistent things.

- Requirements. Each machine requires a separate operator, and directing the tools necessitates a large degree of specialist involvement. To make a variety of items, operators of conventional machining must have extensive knowledge, talents, and experience. Because the CNC process requires minimal operator involvement, a single operator may run numerous machines with a high degree of accuracy and precision, lowering labor costs.

4. What industries use CNC machining or CNC parts?

CNC machining offers parts, components, and products for almost all industries, typical applications are including automotive, aerospace, electronics, agriculture, food, medical, oil and gas, military, marine, household goods, semiconductor, consumer, etc.

5. Why use CNC machining?

CNC machining is a profitable manufacturing method for precision components, it brings plenty of advantages.

- Minimize the material waste

- Avoid human errors and defects

- Higher accuracy and more efficient production

- Mitigate the possibility of accidents

- Bring down the manufacturing cost

- Decreases the energy losses

6. What are the standard tolerances of CNC machining?

± 0.005"or 0.13mm is the standard tolerance for machined metal parts,and+/-0.010" is common for plastic parts. The specific tolerance is depending on the material and drawing. We can discuss tight tolerances based on your drawing.

7. How much does CNC machining cost?

When you start a project, you should know the cost of the CNC machining service needed. In short, the CNC machining cost is determined by the material, part size, machine type, design complexity, quantity, etc. Below are some typical machining costs in different conditions.

- 3-axis CNC Turning: 20$ per hour

- 3-axis CNC Milling: 20$ to 30$ per hour

- 4-axis or 5-axis CNC Milling: 35$ to 50$

- Aluminum 6061: $25 per block

- Stainless steel 304: $90 per block

- ABS: $17 per block

- Nylon 6: $30 per block

In addition, there are also additional costs that need to be included in the total cost, such as the surface treatment or post-processing cost when the part require special surface finishing service, and shipment cost, especially for a large amount of parts or large-sized products.

How do you know the CNC machining cost? We have a particular system to calculate the cost of machined parts quickly from a CAD file, if you want to know the price of components, you can go to our online quoting page, and upload your CAD drawing to get an instant CNC machining quote. Our quote is completely free and supports multiple formats, just simply drag your 3D file to the correct place and leave your custom requirements, and you can find how much your custom part cost with CNC service.

8.How to reduce the cost of CNC machined parts?

To reduce or save CNC machining costs, you can start with those factors that affect the cost.

- Choose the right material within your budget. For example, aluminum is one of the cheapest metals to machine and it is the proper material for many industries.

- Optimize your design. The drawing features will affect the machining time and difficulty, choosing the right wall thickness, radii, and other features will save time and cost.

- Reduce complexity. The more complex the part is, the more expensive it will be.

- Consider the size of the workpiece. The less material you use, the lower the cost will be.

- Set-up costs. Reduce the number of part rotations or repositioning needed to minimize the set-up cost.

- Tolerances. Only use tight tolerance when it is essential.

- Reduce surface treatment. Too many surface finishes will inevitably increase the total price.

9. What is CNC Machining Center?

When it comes to the equipment for CNC machining services, you should understand the machining center. A CNC machining center is primarily an advanced CNC manufacturing machine tool that based on a computer-controlled automation system, can perform a variety of machining operations with high precision, to modify the shape of the workpiece or part to be machined. There are two types of machines. One of them featured in the material to be processed is fixed, attached and stationary to the machine, while the cutting tool moving to work, which is suitable for square or rectangle shapes, another type is reverse, the part is rotating while the tool remains static, allows to mechanize other types of pieces. For example, the common CNC milling machines with an automatic tool changer, a table that clamps the workpiece in place, and an enclosure are classified into the CNC machining center. The spindle orientation is its most fundamental defining characteristic. According to the number of axes, there are 3-axis/4-axis/5-axis machines.

10. What are the different types of CNC machines

You can choose a variety of different CNC machines according to your budget, material and part to be processed.

- CNC lathe machines

- CNC milling machines

- CNC drilling machines

- CNC routers

- CNC plasma cutting machines

- CNC laser cutting machines

- CNC waterjet cutting machines

- CNC electrical discharge machines
