What Exactly Is CNC Robotics?

CNC robotics refers to any robotic method that assists in the CNC machining process. A CNC robot is an advanced piece of machinery built primarily for machining. This type of equipment handles various jobs on its own by following pre-programmed processes. In most circumstances, these robots do not require any human intervention.

CNC robots deliver greater factory automation benefits, assuring mass production and delivery of high-quality components for a variety of sectors. These CNC machines profit not only from robotic implementation but also from the manufacturing of robot parts.

CNC Components Manufacturing for the Robotics Industry

CNC machining is commonly utilized to create custom parts for the robotics sector. Robotic applications are frequently highly customized to their use case. Because of the economically unique products at low volumes, CNC Machining is the appropriate product solution. CNC Machining may be used to make robots parts in the following situations:

  • CNC Robotic Arm
  • End Effector
  • Custom Jigs and Fixtures
  • Sensors and Controllers

Why is CNC Machining the best method for making robotic parts?

Apart from the cost advantages of CNC machining over conventional molding or additive processes, there are numerous other major reasons why CNC machining is the procedure of choice.

To begin with, CNC machined components have shorter lead times than many other methods. Design to completion might take as little as a few hours. This enables the quick iteration and improvement that many specialized robotic applications demand.

Second, in robotics, dimensional precision is critical. Robots frequently work between fixed locations in space and cannot tolerate huge dimensional fluctuations. Got It Made provides CNC Machining to a standard tolerance of 0.05mm, with greater tolerances available on request. This is critical for applications that need accurate, repeatable motions.

Lastly, CNC Machining enables for accurate surface finish control. Part flatness and surface roughness are key qualities in many robotic applications where grasping or suction is required. CNC machining may create items with surface roughness as low as Ra 0.8m, or even lower with additional finishing procedures.

Commonly Used Robots in CNC Machining

Articulated Robots

These are the most prevalent industrial robots. They have rotating joints, often called as axes. Some articulated robots are basic two-axis designs, whereas others have ten or more axes. All robotic axes in these robots provide additional degrees of freedom to ensure such robots’ autonomous mobility.

Because of their increased range of motion and flexibility, articulated robots are perfect for handling a wide range of workpieces, regardless of size. Typical uses for these robots include:

  • Arc welding
  • Material Handling
  • Part transfer and packaging
  • Assembly
  • Machine loading

SCARA Robots

Compliance on a Case-by-Case Basis The Articulated Robot Arm (SCARA) is a four-axis robot designed to do high-speed, repetitive tasks. These robots function similarly to human arms, but with more speed and precision. They also have small footprints, which helps them carry modest weights.

Their speed and efficiency assist to save expenses and increase output while also assuring worker safety. SCARA robots are most commonly used for:

  • Assembly operations
  • Pick and place
  • Machining
  • Packaging
  • Inspections

Delta Robots

These are parallel-type industrial robots that are utilized in high-speed production applications. Its moniker is derived from their distinctive upside-down triangle shoes. They are frequently installed on top of work areas, which are typically conveyors that transport items along manufacturing lines.

Delta robots have a major edge over other robots due to their unique configuration and mechanical construction. Delta robots’ strength is commonly used in the following applications:

  • Assembly
  • Disassembly
  • Packaging
  • Pick and place
  • Sorting

Gantry or Cartesian Robots

These linear industrial robots operate on three axes utilizing the X, Y, and Z Cartesian Coordinate systems. Gantry robots are popular due of their very adaptable setups. The accuracy, size, speed, and stroke length of the robot may all be simply adjusted.

Cartesian robots are bigger and have a greater range and payload. As a result, they are appropriate for dealing with workpieces that are heavier than typical. Among their applications are:

  • Assembly
  • Loading and unloading
  • Material handling
  • Pick and place systems
  • Fastening and screw driving
  • Packaging
  • Cutting – Laser & Waterjet

Differences between robots and CNC Machines

CNC machines are commonly acknowledged to produce more precise outcomes than robots. Calibration can enhance robot accuracies; nonetheless, the accuracies of CNC machining might be fractions of a micron, as contrast to robots, whose accuracies are known to be 100s of a micron.

Another significant distinction between CNC machines and robots is the rigidity of axes. In comparison to robots, CNC machines offer increased stiffness in all directions, allowing for more durable production.

Recent advances in Computer-Aided Design have resulted in a new approach to CNC machining, allowing for a greater usage of robots to help in finishing or machining applications.

Spindle makers, for example, a critical component of CNC machines, are now offering high-speed motorised spindles that are particularly built for robotic machining and have the following features:

  • Lightweight construction (to minimize payload stress)
  • Minimized risk of contamination threats due to advanced sealing
  • Ability to operate at multiple orientations and angles

Robots offer the following characteristics, which is why they are seen as aiding the CNC machining process:

  • Efficiency
  • Speed
  • Accuracy
  • Safety
  • Versatility


CNC robotics is an exciting new production technique. Combining CNC machines and robots, which help create robots for your applications, also helps achieve remarkable results in component manufacturing. We’ve spoken about the benefits of both technologies, as well as their contrasts and overlaps.
