In metalwork, a CNC plasma cutter table is an actual game-saver. You could be a small business owner, a hobbyist, or a large-scale manufacturer, but you need the right table to bring precision, efficiency, and cost-effectiveness. There are just so many options to select from, so you must consider some essential factors before you make the purchase. Let’s explore how to purchase the best CNC plasma cutter table for your needs.
1. Description of CNC Plasma Cutting
CNC plasma cutting is cutting electrically conductive metals, primarily steel, aluminum, and copper, by the medium of a high-temperature plasma torch. A CNC plasma cutter table provides the necessary solid platform. It applies an automated system for the accuracy and precision of the operation of the cutting torch and thus enables set reproducible and precise cutting.
2. Important Considerations
A. Table size and cutting area
The table size determines how much you trim the dimensions according to the material. Remember:
- Small tables (2’x2′ or 4’x4′): suitable for hobbyists and small shops.
- Medium tables (4’x8′ or 5’x10′): used by small business and custom fab shops.
- Big industrial tables (larger than 6’x12′): employed for high-volume manufacturing and heavy-duty operations.
Select a table size based on your most-frequently-used material dimensions and space limitations in your workshop.
B. Plasma Cutter Compatibility
Not all CNC tables include an embedded plasma cutter. If you already possess a plasma cutter, ensure it will work with the table you will buy. In fact, you should consider:
- Amperage capability
- Cut speed
- Material thickness ability
- Higher amperage plasma cutters will cut more material but may require a heavier table.
C. Table Type: Water vs. Downdraft
CNC plasma tables use water or downdraft tables to control smoke and debris.
- Water tables bring the cutting area down to reduce smoke, heat, and distortion. They are quieter and help calm.
- Downdraft tables suck fumes and debris away with fans and filters. They work best in cleaner shops and industrial environments.
- Select based on your ventilation needs and material handling requirements.
D. Precision and Software Compatibility
The accuracy and precision of any CNC plasma cutter table rely significantly upon the design of controlling software. Consider the following:
- Servo motors are superior to stepper motors: They can provide higher speeds and more accurate positioning.
- Control software: Check if the table accommodates well-known applications such as SheetCAM, AutoCAD, or Fusion 360.
- Torch height control (THC): It will automatically adjust the torch’s height to maintain an even cut over an irregular surface.
E. Durability and Construction
Sturdy frames guarantee good stability and longevity over many years. Steel-framed tables exhibit some measure of resistance against warping and, therefore, remain longer usable. Consider:
- Heavy-duty gantries that permit smooth movement
- Reinforced frames capable of handling heavier material
- Precise rails and bearings for precise cut
Conclusion
Choosing a plasma table cutter primarily relies on your requirements, workshop space, and financial situation. An appropriate CNC plasma cutter table should meet general needs: table size, suitability with the plasma cutter, fume control, accuracy, reliability, and affordability.
Spend at the right table, and wonders may be achieved on your efficiency and productivity as a metal fabrication craftsman so you can execute projects with precision and profit. With all that information at bay, you can make the best choice when purchasing the CNC plasma cutter table best suited to address all of your business or hobby requirements. Have fun cutting!
