Most CNC machining services are only equipped to handle light- to medium-duty projects, which can leave you stuck when you have a big job to do. Large CNC Machining is here to help.
Large parts CNC machining is a type of CNC machining that involves the use of large machines. These machines are typically used to create parts for large parts, vehicles, and other large objects.
This blog post will explore large parts machining and its precautions and applications. Stay tuned!
What Is Large CNC Machining?
Large CNC machining using computer numerically controlled (CNC) machine tools to remove material from heavy workpieces. This machining is typically used to create large, complex parts and structures that would be challenging or impossible to produce using traditional methods.
The size of the part dictates the size of the CNC machine, which can range from a small benchtop model to a massive structure that occupies an entire factory floor.
Cautions For Large Parts CNC Machining
CNC machining is a complex process that requires precision and care. There are some cautions you need to take when performing this type of machining, particularly if you are working with heavy materials.
Space
CNC machine tools can be huge and heavy, making them difficult to move and requiring a large workspace. When choosing a workspace for CNC machining, it is essential to consider the size and weight of the machines. The workspace should be tall enough to accommodate the height of the machines and wide enough to allow for easy movement.
Temperature
In large CNC machining, the material is removed by rapidly moving a cutting tool across the surface of the workpiece. The high speeds and forces can generate a significant amount of heat, which can cause the workpiece to deform.
To prevent this, manufacturers often use coolants or lubricants to dissipate the heat and keep the workpiece cool. They may also use special techniques to avoid generating too much heat, such as using different cutting tools or altering the speed of the cut.
Weight
When performing heavy CNC machining, it is vital to take measures to support the workbench. Otherwise, the enormous weight of the machined material could cause the workbench to collapse.
One method to do this is to put a wood block under the workbench. This will help distribute the weight evenly and prevent the workbench from tipping.
Another option is to use a metal stand. This will provide more sturdy support for the workbench but add more weight to the overall setup.
Regardless of your choice, ensure the support is secure and won’t shift during the machining process.
Collisions
Because of the large volume of material that is being machined, there is a greater risk of collisions. To prevent this, the CNC machine must be properly calibrated. And the operator must have a good understanding of the project and maintain control of the machine throughout the process.
High Pressure
Large parts machining exerts tremendous pressure on the materials being worked on. This can cause the materials to lose their shape or even break.
To prevent this, it is essential to use high-quality materials designed to withstand high-pressure levels. And the pressure must be evenly distributed across the material’s surface to avoid weakening or damage.
Loading Tools
Large parts CNC machining makes it difficult for humans to move bulky materials. So, a loading tool is essential for efficiently loading and unloading parts.
The tool helps to securely grip the workpiece, allowing it to be moved without damage. And it can quickly release the workpiece when it is in the proper position.
Without it, the process would be significantly slowed down, and there would be a greater risk of damage to the workpiece.
Use CNC Router
One of the most significant benefits of CNC routers is their large working envelope. This means they can usually handle larger parts than other machining equipment. CNC routers are also extremely precise, making them ideal for high-accuracy tasks.
Surface
A big fly cutter can smooth large materials in large component machining. The fly cutter is a circular cutting tool with multiple blades that rotates on a spindle. This cutter is ideal for machining large materials because it can make very smooth cuts.
When choosing a fly cutter, it is vital to consider the size of the material and the type of finish you want. If the cutter is too small, it will not be able to cut through the material. If the cutter is too big, it will create a lot of vibration and damage the material.
Equipment For Large CNC Machining
Transport Equipment
In heavy machining centers, the large processed materials require special transport equipment to move them into the processing area. This transport equipment can include cranes, hoists, and conveyors. Once the material is in the processing area, it can be laser cut, shaped, and finished using various methods, including lathing, milling, and drilling.
Shapers
A shaper is a machine used for large machining. It is a large, powerful machine capable of removing large amounts of material from the material.
Shapers typically create flat surfaces but can also create shapes and contours. Shapers are very versatile machines and essential to many manufacturing operations.
Grinding Machine
A grinding machine uses abrasive wheels to remove material from the material.
The grinding wheel is mounted on a spindle and rotates at high speed, removing material from the workpiece as it passes. The grinding process will generate lots of heat, so coolants are typically suitable for keeping the workpiece and tools from overheating.
Grinding machines can remove excess material from a workpiece, create a smooth surface finish, or create a desired shape or contour.
Applications of Large CNC Machining
A. Aerospace industry
The aerospace industry heavily relies on large machining for the production of large aircraft components. From wing structures to engine parts, CNC machines can accurately fabricate complex and critical components with high precision and reliability. Heavy CNC machining ensures the tight tolerances required for aerospace applications, enabling the industry to meet strict quality and safety standards.
B. Automotive industry
In the automotive industry, large CNC machining plays a crucial role in the production of complex engine parts. Cylinder heads, engine blocks, crankshafts, and camshafts are just a few examples of components that require precision machining.
