FAQs About CNC Machining Services
Check out some of the frequently asked questions about CNC machining parts and some facts about YIJIN Hardware
Chinas top custom CNC machining parts manufacturer.
1. What is CNC machining?
CNC (Computer Numerical Control) services, also known as CNC machining, are widely used in the manufacturing process across different industries.
An experienced operator usually uses a specialized machine tool to program a set of operations according to your part design.
The control system of the CNC machine allows the tool to perform the set operations and movements so that the final parts can meet your specific requirements.
2. How much does the CNC machining service cost?
The CNC machining cost depends on many factors and varies among different situations.
The material is a big factor. The machining difficulties can vary greatly depending on the materials you choose, which will affect the CNC machining cost.
The design complexity also makes a difference in the CNC machining cost.
It’s easy to understand that the more complex the design is, the more machining process is required and the higher the price will be.
Other factors such as market fluctuation and the order quantity can also affect the final quotation.
If you want to know the CNC machining cost for your project, send us a message and you will receive a quotation with manufacturing advice within 24 hours.
3. What are the major types of CNC machining?
There is a wide range of CNC machining services. YIJIN Hardware covers the most popular types that can support most of your CNC machining designs and projects, including the following:
- CNC Turning Services
- CNC Milling Services
- CNC Boring Services
- CNC Drilling Services
Other precision CNC machining services are also available on demand. Contact us to discuss details and get an instant quote.
4. What is a CNC machining center?
CNC machining center is basically an automated machine tool with a programmed control system.
Based on the position of the spindle, CNC machining centers can be divided into vertical, horizontal, gantry, and universal types.
Vertical CNC Machining Center:
The vertical CNC machining center usually adopts the column structure in fixed positions and a rectangular worktable.
There are usually three linear motion coordinates (X, Y, and Z axes) on the worktable although a fourth axis (A) can also be installed.
The vertical CNC machining center has a compact and simple structure with a lower price tag.
It’s easy to operate, observe the operations during the machining process, and debug the program if anything goes wrong.
This type of machining center is suitable for creating plates, sleeves, and plate parts.
However, the large parts with tall height can not be handled with a vertical CNC machining center due to the column’s height restrictions and its tool change mechanism.
Horizontal CNC Machining Center:
The horizontal CNC machining center adopts movable columns and the headstock between the two columns moves up and down along the guide rail during the manufacturing process.
There are usually three motion directions: Axis X moves between the left and right sides, axis Z moves between front and back, and axis Z moves between the up and down.
A fourth axis A can also be installed on the worktable just like the vertical CNC machining center.
The horizontal CNC machining center is often used for manufacturing spiral wires and cylindrical cams.
It’s not that easy to observe the debug program, test the pin cutting, monitor the manufacturing process, and clamp and measure parts.
However, it’s easy to discharge pins during the process.
Compared with the vertical CNC machining center, the horizontal types feature a more complicated structure that takes up larger space and leads to a higher price.
Gantry CNC Machining Center:
In most cases, the gantry CNC machining center features a vertical spindle, an ATC system and replaceable spindle head accessories.
The system is very functional and can be used for multiple purposes with a single machine.
This type of CNC machining center is suitable for parts of large sizes.
Universal CNC Machining Center:
The universal CNC machining center is a five-sided machining center. It features the functions of both the vertical and horizontal CNC machining center types.
When a workpiece is clamped, all sides, excluding the mounting surface, can be completed at one time.
There are basically two types of universal CNC machining centers:
1) The one that can work as a vertical or horizontal CNC machining center with the spindle being able to rotate 90°
2) The worktable rotates 90° with the workpiece and the spindle remains in the same direction
5. How to choose a reliable CNC machining service provider?
Choosing a reliable CNC machining manufacturer is crucial to get high-quality parts as desired.
There are several things you need to take into consideration when searching for the best CNC machining service provider:
1. Reputation
A good reputation means the CNC machining company is striving for customer satisfaction with quality products and after-sales service.
Always check out the comments from its previous customers to decide whether to work with the CNC machining service provider.
2. Product Quality
The quality of CNC machining parts is the top consideration for your purchase.
A reliable CNC machining manufacturer should listen to customers’ voices and produce the parts strictly according to the client’s requirements.
At YIJIN Hardware, you can even configure the models and the guide rails to meet your specific accuracy requirements.
3. After-Sales Service
Good after-sales service doesn’t mean the products are problematic. It shows that the CNC machining manufacturer is reliable, so you can always find support if anything goes wrong.
YIJIN Hardware has a very efficient and professional after-sales team that handles your issues in a timely manner.
Besides that, a follow-up is carried out after purchase and service to make sure you are satisfied with the CNC machining parts.
4. Qualitifications & Certifications
There are a lot of CNC machining manufacturers on the Internet and the information can be dazzling.
Be sure to check out their qualifications and certifications (preferably revealed by third parties) before you place the order.
If you are shopping online, pay attention to the store’s rate, customer reviews, and the age of the store, which greatly reflects whether the CNC machining supplier can be trusted or not.
Choosing a satisfying CNC machining service provider requires extensive research and comparison.
If it’s possible, you can make a field trip to select the best company for your project.
