The robotics industry can’t bear the flaws in precision as it can ruin the automation industry and manufacturing operations entirely. If you want to manufacture robotics parts with negligible error, then CNC machining is the best choice.

If you want durable, robust and highly agile robotics parts, CNC machining covers you. CNC machining manufactures the perfect surface roughness, which decreases the wear and tear of robotics parts. If you want your robots to face minimum friction with great power to operate long-term, CNC machining is the best way. CNC machining can manufacture robot parts with a surface roughness of Ra 0.8μm.

How Useful are Robots for CNC Machining?

Robots are very useful in some operational mechanisms of CNC machining. Although robots and CNC machining are crucial to industrial automation, they vary greatly. CNC machining is robust and highly agile for carrying out the manufacturing of specific products. At the same time, the robots are versatile and have insane adaptability to carry out different functions throughout their lifetime.

Robotics is advancing quickly without any potential to replace CNC machines. It is evident that robots are agile, powerful and durable, but their operational capacity and precision are not a match with CNC machining. At some technical issues, CNC robots lag behind CNC machining. The CNC machining process is robust and manufactures the products with insane precision and durability by maintaining the pressure and speed of manufacturing.

However, at some levels, robotics machinery may seem a suitable alternative, but it will still not replace the 3-4 axis CNC machining process. Instead of manufacturing, the robot can help the CNC machining through operator-led processes. So, let’s see how robots can help CNC machining.

How Robotics are Helping CNC Machining?

Robots are tremendously helpful in some operations in CNC machining. CNC machining is efficient in semi-automated production. However, there are some operations for which the help of robots is essential.

Robots are aiding CNC machining in hand-finishing tasks, polishing operations and much more. To save time and cost, a CNC robot with 5-axis capabilities can perform the following tasks:

  • Unloading finished parts
  • Controlling the process
  • Loading the raw material into the machine
  • Quality control through automated inspection

Saving time is the greatest concern during CNC machining. Surprisingly, a robotic CNC arm can control the whole process and can pack the final product. It can move things from one machine to another, saving time, cost and energy.

Role of CNC Machining in Manufacturing Different Robot Parts

The Robotics Industry is a big market in industrial automation with a wide range of applications. There are many types of robots, each of which has a specific application. Some of the prominent types of robots are given below:

Articulated robots have a single arm with many joints.

  • Delta Robots have joints at the bottom with the ability to move arms to pick and drop the loads and different things.
  • SCARA (Selective Compliance Articulated Robot Arm) can move things between two parallel planes. It has high vertical stiffness.
  • Gantry/ Cartesian Robots can move at 90 degrees.
  • Each of the above-listed robots has different applications and construction

However, the following four main components make up most of the robots.

  1. Custom clamps and fixtures
  2. End-effector
  3. Robot arm
  4. Motors

Let’s learn more about these four components of robots in more detail.

1. Custom Clamps and Fixtures

Custom jigs and fixtures are not part of the robots but are essential for their operations. You need to hold things in place so the robots can work smoothly. You can also use the fixtures to keep the position of different parts of the robots in place during the work.

Each jig and fixtures have different sizes, geometric shapes, and CNC material. So, CNC machining is the best process through which you can manufacture the custom clamps and fixtures in less time and cost-effectively.

2. End-Effector

End-effectors are essential to take diversified working from the robots. It attaches to the end of the robot arm for different robotic operations. An end-effector is made up of CNC materials such as aluminum and sleet. The perfect working of robots depends on the end-effector, often called grippers, vacuums and graspers.

3. Robotic Arm

In industrial automation, robotics and CNC machining are playing significant roles. There are many components in which CNC machining helps robotics manufacture the parts, one of which is the robotic arm. A robotic arm has to be strong, durable and flexible. So, strong and hard CNC materials, such as aluminum, steel and different plastics, are used to manufacture it. Moreover, different types of robotic arms, such as shoulder, elbow and write joints, rotate. CNC machining is also effective in manufacturing small parts of the robotics arms, such as gears, bearings and small parts of the housing around the arm.

4. Motors

There are many parts of robotics motors that are CNC machined. The motor is an essential component of the robots necessary to move the arms and joints. Typically, the housing of the motors, the brackets, shafts, and bearings are CNC machined. CNC operators can use the CNC lathe and CNC milling to reduce the diameter and add the keys and slots. In this way, CNC machining is tremendously useful in the robotics industry.

3 Key Differences between CNC Machines and Robots

There are many differences between CNC Machines and robots. Let’s overview three key differences between their functions and accuracy.

  1. CNC machines are more accurate in precision as compared to robots. The robots may need an accuracy of 100s of a micron compared to the CNC machines, which would need the accuracy of a fraction of a micron.
  2. In manufacturing the different parts, the stiffness of the machines is one of the most important things. Robots have less expertise in manufacturing as compared to CNC machines. So, the axial stiffness is very low in robots compared to the CNC machines.
  3. In recent years, the technical developments in CNC have led to a whole new manufacturing process. CNC machines only need Computer-Aided Design (CAD) files to manufacture the most precise and accurate products compared to robots.

The market for CNC machining is expanding exponentially. It is estimated that the CNC machining market will surpass $23 billion in 2026. More importantly, some countries are leading in industrial automation, such as Japan, China, Germany, South Korea and the United States of America.

So, CNC machining will always find its way even in the toughest industries. The Robotics Industry is helping the CNC machining in loading, packing and moving the heavy load from one place to another. However, the role of CNC machining is very important in the robotics industry.

The robot arms, gears, fixtures, motors and jigs are CNC machined. Though robots may offer some fronts the speed, versatility and safety, they lack far behind the CNC machines in accuracy, stiffness and precision.
