CNC milling machine: The Ultimate FAQ Guide
Table of Contents
CNC milling machines are still the most common machine tool in the manufacture of metal parts. The most common milling machines are vertical machining centers and horizontal machining centers.
The range of vertical and horizontal CNC machining centers ranges from 3-axis CNC milling machines to 5-axis CNC milling machines. If you want to buy a CNC milling machine then this guide is for you.
1. What is a CNC milling machine？
CNC Milling Machines are incredibly useful pieces of machinery to both commercial and industrial production.
The aerospace industry, the medical industry and the electronics industry are all able to benefit from the products of CNC Milling , and what makes them so unique?
CNC stands for Computer Numerical Control milling.
This essentially means that the milling machine is moved and monitored by numerical computer control, rather than by hand.
CNC milling tools perform a machining process similar to drilling and cutting parts with incredible precision, and therefore leave no room for human error.
The process is an increasingly popular industrial solution since it can accommodate detailed sizes and shapes of all kinds of material.
2. What are the types of CNC milling machines？
There are many types of CNC milling machines, which can be divided into vertical CNC milling machines and horizontal CNC milling machines based on their structure and motion form.
3-axis CNC milling machines, 4-axis CNC milling machines and 5-axis CNC milling machines are distinguished by the number of axes.
These are the commonly used types of CNC milling machines in actual work.
3. How does a CNC Milling Machine work?
The main work of the CNC milling machine is milling and drilling. Of course, different types of CNC milling machines have different working forms.
The vertical CNC milling machine has the spindle vertically moving up and down while the CNC horizontal milling machine spindle is moving up and down horizontally.
4. What Is a Vertical Milling Machine?
The most common type of milling machine, a vertical milling machine features a vertically oriented spindle that holds, as well as rotates, the cutting tool against the stationary workpiece.
The spindle is capable of moving up and down — all while pressing against the workpiece to remove material.
There are actually two distinct types of vertical milling machines: turret milling machines and bed milling machines.
In a turret milling machine, the spindle and table can move perpendicular and parallel to the axis. In comparison, bed milling machines only move the table perpendicular to the axis.
Many manufacturing companies prefer turret milling machines because of their versatility.
They are able to perform a wider range of milling operations than bed milling machines, making them a smart investment for manufacturing companies.
5. What is a Horizontal Milling Machine?
Horizontal milling machines feature a similar design in which a spindle containing a rotating cutting tool presses against a workpiece to remove material from the workpiece.
With that said, horizontal milling machines differ from their vertical counterparts in several ways.
The biggest difference between these two types of milling machines is the orientation of the spindle.
With vertical milling machines, the spindle features a vertical orientation. With horizontal milling machines, the spindle features a horizontal orientation. In other words, horizontal milling machines mount the cutting tool on a horizontally oriented spindle that’s able to selectively remove material from the stationary workpiece.
Furthermore, horizontal milling machines usually feature different cutting tools than vertical milling machines.
While vertical milling machines usually have long and thin cutting tools, horizontal milling machines have shorter and thicker cutting tools.
Horizontal milling machines are able to perform heavier, deeper cuts than vertical milling machines. As a result, manufacturing companies often use them to cut grooves or slots into workpieces.
Hopefully, this gives you a better understanding of the differences between vertical milling machines and horizontal milling machines.
6. What is a 3-axis CNC milling machine?
Our most common CNC milling machine is usually a 3-axis CNC milling machine.
It is composed of 3 axes of motion, X, Y, and Z.
3-axis milling evolved from the practice of rotary filing, and is a milling process that operated on two axes, the X & Y axis.
In 3 axis machining, the workpiece remains still while the cutting tool moves along the three axes to mill the part.
3-axis machining still one of the most widely used techniques to create mechanical parts, and can be used for automatic/interactive operation, milling slots, drilling holes, and cutting sharp edges.
7. What is a 4-axis CNC milling machine?
4-axis CNC milling machine is evolved on the basis of three-axis
4-axis CNC milling machine includes four movable axes X, Y, Z, A
This adds a rotation about the X-axis, called the A-axis.
The spindle has 3 linear axes of movement (X-Y-Z), like in 3-axis machining, plus the A-axis occurs by rotation of the workpiece.
There are a few different arrangements for 4 axis machines, but typically they are of the ‘vertical machining’ type, where the spindle rotates about the Z axis.
8. What is a 5-axis CNC milling machine?
5-axis CNC milling machines, also called 5-axis machining centers, are generally divided into three types.
Head rotating type, table swing type, 3+2 type five-axis CNC milling machine.
A 5-axis CNC machine has two extra rotary axes which opens the door to an infinite number of machining possibilities.
The types of rotary axis include rotary axes A, B and C which rotates around the X-axis, Y-axis, and Z-axis respectively.
While these are three extra axes and not two, they’re still considered 5 axes in total.
The combination of the additional axes is machine dependent and can come in any combinations of AB, AC or BC.
9. What are the benefits of CNC milling machines？
You will find many of its benefits when using a CNC milling machine.
The following are the main advantages of using a CNC milling machine.
CNC milling machines can bring you higher processing efficiency, you do not need to be equipped with a worker for each milling machine like a manual milling machine. One worker can operate several CNC milling machines at the same time. The CNC milling machine is more efficient, which makes its return rate higher.
Master the operation of the CNC milling machine, you can realize mass production by making fixtures, and you can complete the processing of multiple products at one time.
The CNC milling machine is controlled by a CNC controller and is equipped with a servo motor, which enables the CNC milling machine to complete more precise processing.
10. What are the other names of CNC milling machines？
CNC milling machine is also called machining center, vertical CNC milling machine is also called vertical machining center (referred to as VMC or VMC machine), horizontal CNC milling machine is also called horizontal machining center (referred to as HMC or HMC machine), of course there are some details Sub-products such as tapping center, double-column machining center (also called gantry machining center).
11. What are the main components of a CNC Milling Machine?
CNC milling machine frame
The frame is the foundation of the CNC milling machine. All other core components of the CNC milling machine are installed on the frame. Different types of CNC milling machines have different frame structures. For example, the frame of a vertical CNC milling machine consists of two parts, one is a column and the other is a base.
The main shaft is one of the core components of a CNC milling machine. All processing tasks are completed by the rotation of the main shaft. The main shaft of a vertical CNC milling machine moves vertically up and down.
The main shaft of the horizontal CNC milling machine moves horizontally up and down.
There are different types of spindles, such as belt spindles, direct-drive spindles, built-in electric spindles, gear spindles, etc.
This is mainly different from its transmission method.
Lead screw and guide rail
Lead screw and guide rail are the core components of CNC milling machine movement.
Its quality affects the accuracy and running speed of the CNC milling machine.
The lead screws and guide rails used by TOPSTAR CNC milling machines are all made by German Rexroth.
We have established a good cooperative relationship before.
The servo system of the CNC milling machine includes a servo motor and a driver.
The power of the servo motor determines its torque.
The torque of the CNC milling machine affects the processing of the CNC milling machine.
At present, mainstream servo motors and drives are matched with CNC controllers, and the main brands are Fanuc, Mitsubishi, Heidenhain, Siemens and so on.
Automatic tool changer (ATC)
Automatic tool changer is the core equipment of CNC milling machine.
Although it is not necessary, it is very helpful for improving processing efficiency.
Avoid the need to frequently change tools in the actual machining process.
Different brands of CNC controllers have a greater impact on the accuracy of surface gloss.
The servo motors and drives of CNC milling machines are usually matched with CNC controllers.
At present, the most widely used CNC controllers are FANUC, Mitsubishi, Siemens, Heidenhain and SYNTEC.
The high-speed rotation of the CNC milling machine spindle will generate a lot of heat during the machining process.
This heat needs to be cooled by the cooling system.
Otherwise, running over temperature for a long time will cause damage to the spindle.
The cooling system is usually oil-cooled. The cooling oil is transferred to the spindle through the oil cooler to make it cool quickly.
The CNC milling machine will continuously move during work.
The lubrication system is to provide continuous lubrication for these movements to reduce the wear on the lead screw and guide rail.
The lubrication system will work intermittently according to the set time.
12. How much does a CNC Milling Machine cost?
Different types of CNC milling machines or CNC machining centers have different prices.
The price of a CNC milling machine is usually determined according to its processing range.
Generally, the larger the itinerary, the higher the price.
In addition, there are CNC controllers, automatic tool changers, spindle speeds, etc., which are all factors that affect the price of CNC milling machines.
13. How to choose a CNC milling machine?
Choosing the right CNC milling machine is a good issue.
Most novices do not know how to choose a CNC milling machine that suits them.
This very much depends on the following key considerations:
- What standard or application is the machine used for?
- How many axes will the machine have? 3 axis or 5 axis
- What is the size of the machine needed (depending on the machined part)?
- Do you need a pallet changer – automatic or manual?
