10 Best CNC Machines in 2024

CNC machines revolutionized part manufacturing, improving productivity by increasing accuracy and material compatibility. Technological advancement, however, continues in the industry, and it shows in the day-to-day development of sophisticated machines.

Investing in a quality and project-aligned CNC machine can determine the success of your machining operation in 2024. Hence, part manufacturers should know about the best CNC machines in 2024 as it will allow them to buy the best or approach the right machining service provider.

This article will help you choose the best machine for your machining operations. It will guide you to the best CNC machines in 2024 by introducing the common types of CNC machines and the top brand manufacturers. 

Common Types of CNC Machines

CNC machines are classified based on the CNC machining operations. There are four types of conventional part manufacturing, and knowing these types will make it simpler to select the right one from our best CNC machines in 2024.  

CNC Milling Machines

Types

CNC mills come in four major types ( 3-axis, 4-axis, 5-axis, and 3+2-axis) based on the number of axes their cutting tools can move. There is also a 6-axis milling machine although it is not common in part manufacturing industry due to its high initial cost of investment. 

A 3-axis milling machine’s cutting tool can move along the horizontal (X), vertical (Y), and depth (Z) axes. Hence, they are cheaper and more suitable for machining parts with simple designs.

A 4-axis milling machine’s cutting tools move along three axes like those mounted on a 3-axis machine. In addition, they can move along the A-axis. This increase in the number of movements ensures that they can machine cylindrical or contoured parts.

The cutting tools of a 3+2 axis CNC milling machine can move along three axes. Furthermore,  the machine can simultaneously position the workpiece in two additional axes. Consequently, they can machine parts with complex designs.  

Lastly, a 5-axis CNC machine’s cutting tools rotate on two axes and move along 3 axes. Hence, they are the best for machining parts with complex designs. 

Applications

CNC milling machines are applicable in several manufacturing industries for machining parts with complex geometries, intricate features, and tight tolerance. Examples include: 

  • Rapid Prototyping and Manufacturing Industry 
  • Aerospace Industry
  • Automotive Industry

Pros

  • High precision and accuracy
  • Versatility and efficiency
  • Suitability for parts with complex designs and intricate features

 Cons

  • It requires a high initial investment
  • Operators need to be experts in CAD/CAM software and G-code programming
  • There is a need for regular maintenance. 

Cost

A CNC milling machine cost depends on the size, configuration, brands, etc. Prices range from $10,000 to $20,000 for small-size machines. High-end industrial machines can cost hundreds of thousands of dollars. 

CNC Lathing Machines

CNC lathes operate based on CNC lathing operation. Here, the cutting tool is mounted for outer or inner diameter while the workpiece rotates on a main spindle. The stationary cutting tool then removes part of the workpiece while it rotates. 

CNC lathes are like CNC mills in terms of classification. Both use several axes with an axis being the way you can approach or rotate the workpiece during machining. 

There are four classifications of CNC lathes and they are 2-axis, 3-axis, 4-axis, and 5-axis. A 2-axis CNC lathe is the basic setup with X and Z axes. This allows the machine to perform cylindrical machining, facing, drilling, and tapping. However, it doesn’t permit milling.

A 3-axis CNC lathe has an additional C axis and life tool system. Hence, they can perform milling, boring, and tapping operations. 4-axis CNC lathe goes further to add the Y-axis. This makes it possible to perform off-center machining operations and make them suitable for parts with complex designs.

Lastly, the 5-axis CNC lathe can move along five axes and the machine adds a turret that allows the usage of two or more tools simultaneously.

The workpiece rotates or turns. Hence, some CNC lathes are called CNC turning machines. Furthermore, a simple lathe has a 2-axis configuration. When a lathe machine has other features like a y-axis and sub-spindles, they are called Turning Centres. 

A turning center goes beyond standard Outer and inner diameter turning operations. They further incorporate CNC operations such as milling, drilling, and tapping. 

Applications of CNC Lathes

CNC lathes are applicable in several manufacturing industries for machining parts with cylindrical shapes, axial symmetries, and shapes. They are critical in the following industries: 

  • Rapid Prototyping and Manufacturing Industry

  • Versatility and efficiency
  • Suitability for parts with complex designs and intricate features

 Cons

  • It requires a high initial investment
  • Operators need to be experts in CAD/CAM software and G-code programming
  • There is a need for regular maintenance. 

Cost

A CNC lathe’s cost depends on size, configuration, brands, etc. Entry-level lathes can range from $10,000 to $50,000, Mid-range lathes can range from $50000 to $200000. Finally, high-end CNC lathes range from $200,000 to several million US dollars. 

CNC Electrical Discharge Machines (EDM)

You can also use hobbyist CNC EDM machines for prototyping and educational purposes. They have a price range of $5,000 to $30,000.

CNC Laser Cutting Machine

CNC laser cutting machines generate laser beams, using it to cut the workpiece. They are precise and accurate, with wide material compatibility. 

There are four main types used in part manufacturing and they include:

  • CO2 laser cutting machines: They use a CO2 lasing medium to generate the laser beam and are suitable for organic materials like plastics.
  • Fiber laser cutting machines: They use a fiber+ytterbium laser source to generate the laser beam. Hence, they are powerful, precise, and suitable for metals and plastics/ 
  • Neodymium (Nd:YAG) laser machines: They use a neodymium-doped yttrium aluminum garnet to generate a laser beam. They are the best option for cutting thick metals
  • UV laser cutting machines: They are very accurate and are suitable for cutting thermosensitive materials. They are the best laser-cutting option for the electronics and microelectronics industry.
