neuma FOUR
Neuma FOUR is a response to a need that Carson Hill, the Neuma creator, noticed in tattoo machines. Several years ago, Carson and several other tattoo artists got together and did an in-depth analysis of many popular coil and rotary tattoo machines. What was discovered were the fundamental differences between these machines, related to the action and behavior of needles. This illustrated a list of problems with traditional rotary machines. The Neuma FOUR is the solution.

THE PROBLEMS
-A rotary machine with a standard waveform will cause a needle to dwell inside the skin during a stroke cycle substantially
-Typical cam/follower relationship limits the amount of variations that can be made to the frequency waveforms
-By implementing a cushion into a rotary machine we effectively extend the amount of time a needle dwells inside the skin
-Standard waveform rotary machines restrict movement of the artists hand by not allowing the needle to retract quick enough for the artist to move their hand quickly across the skin without causing unnecessary tissue damage
-Modern pen-style tattoo machines, being built around cartridge technology and utilizing traditional rotary mechanisms results in ever-increasing diameters and lengths of these pens
-Pen-style machines have a layout which puts the motor weight outside of the hand, making the ergonomics awkward due to the imbalanced design
-Machines with available variable stroke lengths require disassembly of the machine in order to vary the stroke which cannot be done quickly during a tattoo
-The waveforms of traditional rotary machines cannot be altered
-The grip of pen-style rotary machines does not cover the machine, and thereby they are susceptible to contamination.
THE SOLUTIONS
-Manipulate the shape of the cam such that a desirable waveform is achieved, reducing the amount of time a needle dwells inside the skin
-Reverse the order of the cam and follower relationship in order to maximize the potential of the dwell in the retracted position
-Simplify the ability to change cams quickly for varied stroke lengths and waveforms, dramatically changing the behavior of the needle for different effects
-Traditional cam waveform can be used as well as any other variation in that waveform
-Remove the cushion from the cam mechanism
-Alter/redesign the motor and mechanism in order to minimize length and diameter of the machine while maximizing power
-Create a more balanced and natural feeling machine by reducing the length and diameter of the machine, while reducing fatigue and strain on the artists hand
-By designing the Neuma FOUR such that the grip covers the entirety of the non-autoclavable portion of the machine, when a grip is autoclaved or disposed of, the artist can be certain that the machine is clean and sterile
-Oversized grips are available if preferred, but not necessary since the motor is inside the hand and closer to the needle
DESCRIPTION
When rotary machines became popular, many people had decided that “cushion” or “give”, or the lack thereof, is the main differentiating factor between coil machines and rotary machines. Coil machines have an inherent “give” and rotary machines do not. This creates a number of issues with rotary machines, related to the way a needle is interacting with the skin.
To begin, needles push back against the resistance of the skin, whereas a coil would normally back off. This action can cause additional trauma/damage to skin tissue, when using a rotary. In addition, when the needle is inserted into the skin, there is a significant amount of dwell the needle experiences. Roughly 40% of the duration of a stroke cycle the needle is inside the skin, versus roughly 10-15% of a cycle that is spent in the skin for a coil machine. The resulting effect of this is a dragging (“catching”)sensation that results in more tissue damage.
When a “cushion” is integrated to a rotary machine, the needle is no longer forced to complete all of its downward stroke, however, this is actually creating a flat spot in the worst possible position of that sinusoidal waveform, the position in which the needle is contacting the skin. What this does is lengthen the amount of time that the needle is hesitating inside the skin to about 50% of a stroke cycle, thereby causing even more tissue damage.
This began an exploration by Neuma developers of possible ways to manipulate the shape of a cam in order to reduce the amount of time a needle would spend in the skin. The Neuma FOUR gets a needle in and out of the skin very quickly, greatly reducing tissue trauma.
Additional priorities placed on the Neuma FOUR are:
-Ability to autoclave or dispose external housing with ease
-Ease of variability of stroke and waveforms
-Reduced size with no reduction in power
-Emphasis being placed on function over form
-Minimal maintenance, maximum lifetime
-Durability, performance, and simplicity
-Relative ease of manufacturing for the purpose of availability
n 2
Neuma was created in 2000 with the birth of its first prototype. It went through a series of other prototypes before it was ready to be sold to the tattooing public. The Neuma 2 was a monumental hit in the tattoo industry, including some of the industry’s best and most well known artists. The N2 is the first available pneumatic tattoo machine in history, and is also the first and only tattoo machine in the world that can be autoclaved, other than the Neuma Hybrid. To date, many thousands of tattooists have used and loved the results of the Neuma 2 tattoo machine. The N2 played a very big part in the popularity and development of rotary tattoo machines.
neuma HYBRID
The Neuma Hybrid was the second machine in our product history. Neuma worked for two years to create a new and improved pneumatic tattoo machine. It was much more tattoo machine than the N2. The Hybrid is a two-year answer to seven years of questions, comments, and suggestions. It has a longer stroke, an integrated cushioning system, and higher rpm’s at a more consistent rate ,with more torque and the ability for an even softer hit. Also, to make things easier for those who don’t want a compressor or who don’t want to travel with one, the Hybrid can be made into an electric machine by combining it with the Neuma Electric Module, so an artist can leave the compressor out of the equation.
neuma ELECTRIC MODULE
Just a few steps behind the Hybrid came the Hybrid Electric Module for electric use of the otherwise pneumatic Neuma Hybrid. Neuma is the very first to offer, maybe even the very first to suggest the idea of a multiple type power source for use in a single machine for tattooing. And not only is the idea sound, but the engineering behind it is absolutely phenomenal. The motors are German made, and they are some of the worlds best electric motors. The Hybrid coupled with its electric module are actually cheaper than buying the original N2 machine with a compressor.
