Skateboard Wheels Enhance Functionality in Plasma Cutter
In an innovative twist, fabricators are now using skateboard wheels to revolutionize the tubular plasma cutting process on CNC machines. This unique approach, popularized by The Fabrication Series, provides an affordable and effective solution for cutting complex shapes on tubular stock.
The key innovation lies in the creation of custom pivoting arms, each fitted with two skateboard wheels. These arms not only hold the tube securely but also allow for precise rotation under the plasma cutter. This setup enables the CNC machine to roll the tube smoothly while making intricate cuts, such as miters and notches, which are challenging with fixed setups.
Skateboard hardware, with its high-quality bearings and wheels, offers an inexpensive and smooth rolling solution for tubes during cutting. The arms pivot to adapt to the tube diameter and maintain secure contact, ensuring accurate cuts every time.
The process begins by modeling the tubes in CAD software, such as Onshape, and converting the 3D pipe model into a sheet metal model usable by the CNC software. Once the model is ready, the CNC machine is set to work. Although it may require a few trial cuts to fine-tune the settings, once dialed in, the CNC plasma cutter handles complex shapes on tubular stock efficiently.
Meanwhile, the plasma cutter torch itself is modified from a handheld unit with a blowback start mechanism. This modification prevents electrical interference with CNC electronics. The torch is slightly adjusted to mount onto a 3D printed holder at an optimized angle for the CNC machine.
To build this setup, follow these steps: 1. Fabricate pivoting arms equipped with skateboard wheels (4 wheels per setup, 2 arms). 2. Model tube geometry in CAD and convert it for CNC cutting paths. 3. Use a handheld plasma cutter torch modified with a blowback start and mount in a CNC-compatible holder. 4. Mount the torch and skateboard wheel arms on a CNC machine. 5. Calibrate and run cuts, adjusting parameters as needed for precise tubular cutting.
This approach leverages skateboard hardware’s affordability and smooth rolling capabilities, making an affordable and effective tubular plasma cutting solution for CNC setups. Skateboard hardware is now not only a popular sporting good but also an elegant and intuitive solution for beginners, with trucks that allow for easy turning.
In conclusion, the integration of skateboard hardware into CNC plasma cutting opens up a world of possibilities for fabricators. With its smooth rolling capabilities and affordable price point, it's no wonder this innovative solution is gaining traction in the fabrication world.
- The use of skateboard hardware, known for its high-quality bearings and smooth rolling capabilities, also provides a cost-effective solution for the manufacturing industry, especially in the context of CNC plasma cutting.
- The affordability and intuitive design of skateboard trucks, a component of skateboard hardware, make them an appealing choice for beginners in the finance and technology sector, as they allow for easy turning and precision movement in the plasma cutting process.
