Some of the Best CNC Machines for Beginners

  1. ELIHU HD SERIES PLASMA

Elihu HD series systems

Compatibility:

The Elihu HD Series CNC systems are configured to operate seamlessly with Hypertherm and Thermal Dynamics conventional plasma power supplies. If the need arises to upgrade to a larger plasma system, a straightforward process involves unplugging the current unit and connecting the new power supply to the compatible CPC port located on the back panel of the new unit.

True Turn Key Systems:

The Elihu HD Series system is shipped with a robust, fully welded steel frame measuring .1875” in thickness, and it arrives fully assembled. With electrical and air supply preparations made prior to the machine’s arrival, the entire system can be set up and ready for operation in less than 45 minutes. Onsite training is available for all customers in the United States but is not mandatory.

Engineered and Tested:

Squickmon designs, manufactures, and rigorously tests all machinery before release. You can trust that your system will operate at its full capabilities. Our team of software, electrical, and mechanical engineers collaborates to create and construct the finest system in the Lite Industrial market.

  1. ELIHU LITE SERIES CNC PLASMA

Elihu Elite series

The Elihu Lite Series CNC plasma system incorporates dynamic torch height control (DTHC), featuring a responsive feedback control that rapidly and accurately adjusts multiple times per second to maintain precise cutting height. This adjustment is achieved by monitoring voltage readings from the torch tip to the material. With advanced functionalities such as DTHC sampling and DTHC on/off control, operators can easily fine-tune cut height settings with just a few clicks within the software. Gone are the days of mid-cut arc voltage adjustments to uphold cutting height, as this fully integrated solution takes care of the task, enhancing cut quality and prolonging consumable life.

The newly introduced Z-axis assembly adopts a proven linear slide design composed of 9 roller bearings (4 adjustable, 5 fixed). This design, carefully chosen for its durability in harsh industrial environments, eliminates recirculating bearings near the cutting zone. The assembly includes an integrated ball screw drive, ensuring smooth and frictionless movement for the DTHC. Additionally, it allows for expansion capabilities, such as pneumatic etching, sharpie marker functions, oxy-fuel cutting, and other multi-process options, all configurable within a single universal design (requires upgraded software option).

Every machine in the series now features a collision detection head. This innovative torch holder design eliminates the need for a breakaway torch mount. Instead of physically dismounting the torch in case of an obstruction, the collision system automatically repositions itself to its exact location without operator intervention. This design employs proximity sensors that trigger if the torch body deviates within 2 degrees relative to its 90-degree cutting position. The holder design also includes standard 2-axis torch squaring, ensuring that the torch can be adjusted for perpendicularity to the cutting surface.

Conclusively, when selecting a CNC plasma cutting machine as a beginner, consider key factors like cutting area, thickness, software, safety, and price. The right choice will enhance your metal fabrication experience, so research and match the machine’s features to your specific needs and goals. With the right equipment and dedication, you can turn raw materials into artistic creations.
