KT Series vs Unimig Stealth vs Arcdroid

Finding the ideal CNC plasma cutter for your specific needs can be difficult. When navigating the market, you may become frustrated with the number of options available with minimal insight on which one to choose. Every dollar counts, so balancing cost and efficiency complicates the search. 

This presents yet another difficulty if you’re looking to cut materials with accuracy and excellent quality. To simplify your selection, this article will examine three different brands of plasma cutters: the Arcrdoid, the Unimig Stealth, and the KT Series.

What is a CNC Plasma Cutter?

A CNC plasma cutter is a thermal fabrication tool that can cut through numerous metals. What sets it apart from other machines is in its name— Computer Numerical Control. The machine is computer-controlled, which allows for a very high level of precision during the cutting process.

What are CNC plasma machines used for?

CNC plasma machines have a myriad of applications. They are used for cutting steel beams, plates, and other structural components quickly and accurately. In a completely different application, CNC plasma machines can cut detailed sculptures, decorative panels, and custom metalwork. 

These machines can slice through thick steel plates, which allows for the efficient production of large-scale metal components used in manufacturing, shipbuilding, and heavy machinery.

Unimig stealth 2400 CNC table

The Unimig Stealth table maintains the optimal height while cutting over wavy or warped material. This method makes sure that you can expect consistent cutting quality, minimal dross, increased consumable life, and faster cutting speeds. 

Automatic Collision Detection and Limit Switches is used on all axes, software algorithms, and real-time data processing to detect and prevent potential collisions.

Best used for

The KT Series is perfect for small to medium-sized workshops. It is an affordable yet high-quality CNC plasma cutting machine. This machine has been designed to keep up with production requirements, which can be extended in the future. The KT Series is easy to operate and maintain, perfect to maximise production without the complexity of more advanced systems.

This ‘no-frills’ machinery investment is also suitable for education facilities, providing a complete CNC package customised to various applications, including a plasma cutter, software, and a full suite of accessories.

Which machine should you purchase?

While all three brands offer excellent plasma cutting machines, the KT Series stands out for accessibility, ease of use, and features. It is an ideal choice for those starting out or looking to upgrade their current setup. 

One of the standout features of the KT Series is its robust construction. Built with high-rigidity linear bearings and heavy-duty stepper-servo motors, these machines are designed for longevity and consistent performance. The precision ‘V’ guideway rack & pinion drive system for the X and Y axes, coupled with a precision ball & screw drive system for the Z axis, ensures accurate and reliable operation. This makes the KT Series capable of handling both detailed artistic work and heavy-duty industrial applications.

The KT Series also offers flexibility and future-proofing. It can be extended to keep up with production requirements, ensuring that your investment remains valuable as your business grows. The optional stainless steel waterbed provides effective fume control and heat-related warpage control, enhancing both safety and performance.

Ultimately, choosing the right CNC plasma cutter depends on your specific needs and budget. The KT Series is a great choice option for those seeking a reliable, easy-to-use, and affordable machine. For more information, check out the KT Series.
