Different Types of CNC Machines: Best Computer Numerical Control Types & Advantages (2020)
Types of CNC Machines!!CNC machining is a vital part of many industries, such as aerospace, medical, automotive, and mining. Davenport Machine brings 100 years of innovation to each project, so every client has a product that meets their specifications and industry standards. So here you will get to know all about CNC machine types.
What is CNC Machines?
CNC Machines(or Computer Numerical Control) machine is an electro-mechanical device that uses computer programming inputs to operate machine shop tools. CNC machining is one common way to create prototypes (the other method being 3D printing).
While there are advantages to both, CNC is faster and stronger as it involves creating something new out of an already solid material. CNC machine programming offers many production advantages over previous methods of machining and is an indispensable tool across many industries.

How Do CNC Machines Work?
- Running on a set of prescribed digital instructions, Types of CNC Machines use computer files to execute a project. These digital instructions are created in either Computer-Aided Design (CAD) or Computer-Aided Manufacturing (CAM) files.
- Once the program is uploaded, an operator runs a test program, often referred to as “cutting the air.” This trial run is an important first step to verifying both speed and tool position because any discrepancies can result in damage to the machine or the part being created.
- To maximize efficiency, CNC Machines combine multiple tools into common cells or units. They produce the desired end product by removing material from the original stock source. This results in a stronger, more durable finished product.
How Many Types of CNC Machines:
Types of CNC Machines
Conventional Technologies Types of CNC Machines
Drills CNC Machine Types and Uses
These operate by spinning a drill bit and cutting it into a block of stock material.
Lathes Types of CNC Machines
These are the opposite of drills. They spin the stock material against the drill bit instead of spinning the bit and cutting it into the block.
Milling Machines Types and Uses
These use revolving cutting tools to remove material from the block. They are the most common type of CNC machine used today.
This highly specialized technology is common in special cases for mass production that use a certain type of material.
Examples of these types of CNC Machines technology include water-jet cutting, plasma cutting machines, and laser cutting machines.
DIFFERENT Types of CNC Machines CENTERS –
For a layman to understand which type of machining center is available to choose from, we can say that there are primarily three types-
- 3 Axis – one can process a profile from TOP, FRONT, and BACK – X, Y, and Z-axis
- 4 Axis – one can process a profile from TOP, FRONT, BACK and any angle from FRONT to BACK – X, Y, Z and A-axis
- 5 Axis means one can process a profile from TOP, FRONT, BACK, any angle from FRONT to BACK and LEFT to RIGHT – X, Y, Z, A, and C axis. In addition, a 5 Axis machine can do cutting, notching, and process from the bottom of the profile too.
USAGE OF CNC Machines IN FENESTRATION INDUSTRY-
Doors and Windows Classification of CNC Machine–
- The average height of Doors is 2.1m. In some cases, it may be 2.4m. In the case of sliding doors, the width could go up to 4.5m. Windows are usually between 1.5m to 1.8m.
- A machine should be able to process a minimum of 1.5m and a maximum of 3.5m with a possibility to machine longer if required by rotation of the profile.
- Machining of lock slots, keyhole, locking points, water drainage slots, can be done on both 3 Axis and 4 Axis machines.
- General Floor to Floor height is around 3.5m. In some cases, it could go up to 4.5m. The minimum processing length in the case of facades is 3.5m and to reduce loading and unloading time, a 2 station machine is advisable.
- Machining of holes for transom fixing, pressure equalization slots, notching at bottom incase of unitized profiles.
POINTERS TO CHOOSE A Types of CNC Machines
- Production Capacity
- Maximum processing length
- Processing Speed – Travel speed in X, Y, and Z gives an indication of the speed of processing.
- Spindle – Aluminium processing requires a minimum of 12,000 rpm. Higher speed offers a better finish. Processing of thicker profiles may require high power spindles.
- Shuttle/Oscillating operation – The machine is longer with 2 stations. The machine will process Station A and then move to Station B. The operator can change the profile in Station A. This will save the time of loading and unloading. It is useful for Unitized facades. Station A can process Male Mullions. Station B can process Female Mullions.
- Compatibility with software / future connections to window production software
- Training and Service.
Components of a CNC Machines System
Numerical control is described as a technique to control various functions of a machine tool with an input. CNC is a microprocessor-based system, the heart, and the brain of a CNC machine. Following are some of the components of different types of CNC Machines system:
- The central processing unit (CPU)
- Input devices
- Machine control panel
- Programmable logic controller (PLC)
- Servo-control unit
- Display unit
A serial communication port is often utilized to transfer data from a computer to a CNC Machines. There are international standards established for serial communications.
The CPU is where a CNC Machines system is controlled. It receives the data stored in the memory as a part program. The data is then decoded and modified into position control and velocity control signals. It oversees the movement of the spindle or control axis. An action is rectified if it does not match the programmed data. The speed control unit works in a harmonious way with the CPU for the movement of the machine axes.
Classification of CNC Machine systems can be applied to a broad range of industrial applications. Following are some of the industries where Machines is used:
- Metal fabrication
- Electrical discharge machining
Advantages of Different Types of CNC Machines
