Milling Machine Control System Leaves a Mark on Tattoo-Machine Developer

When the prototyping process wasn’t able to keep pace with creativity, applying Heidenhain’s Acu-Rite MillPwr G2 control on this tattoo machine designer’s Webb milling machine enabled faster prototyping.

Manually designing and developing tattoo machines takes time. This can be a serious roadblock for a creative person like Dan Kubin, who needed a faster way to produce his prototypes. By purchasing an Acu-Rite MillPwr G2 control from Heidenhain Corp. (Schaumburg, Illinois) and installing it on a new milling machine, Mr. Kubin was able to cut the time he spends making prototype machines by a day or more, and increase the options on and availability of his products.

“I’ve really been able to up my game,” he says.

Mr. Kubin became interested in tattooing in 2005 while he was serving as a machinist and welder in the U.S. Air Force. He is both a tattoo artist, which he practices two days a week at a private studio, and a maker of the small machines used to apply tattoos, spending the rest of his week at his home workshop in Independence, Missouri, making such machines for customers around the world. These rotary tattoo machines sell out within hours of his uploading their listings on Sunday nights to his website, They are described as reminiscent of “steampunk” style, a retro-futuristic take on technology that often incorporates bright brass and copper. “If it is steampunk, that is unintentional. All I can say is that I like this look, as well as the use of brightly colored finishes, and working with brass and copper,” he says.

When Mr. Kubin was designing and developing his tattoo machines manually, he outsourced the machining in bulk. This system was unsustainable, however, due to the number of different designs he makes, combined with the custom nature of the work. His constantly evolving creativity was frustrating for everyone involved, he says.

Instead of spending a day and a half using a small, hobbyist-type benchtop mill with a digital readout and a rotary table to create the basic frame of new tattoo machine prototypes, Mr. Kubin decided to buy a milling machine with a control so he could develop parts exactly the way he wanted within his own timeframe.

After visiting Accurate Measurement Systems (AMS) in St. Louis, Missouri, last fall, he bought a demo Webb 4EVS-XL-HC-220V milling machine right off the floor. The two-axis machine has a “turbo” power knee and enables Mr. Kubin to draw ideas in CAD and load the DXF files directly into the MillPwr control via USB.

“Since his market demand continues to swell due to the appearance and performance of his rotary tattoo machines, he felt a driving force to acquire something that could get his ideas to the CNC shop quicker. The G2 has allowed him to do that,” says AMS’s Ed Albeitz.

Mr. Kubin says that using the new milling machine and control system allows him to create his first prototype tattoo machine in half a day, and since he programs as he goes, a second one takes just an hour. Features such as the mill’s quill and W axis have been key to speeding up the prototyping process, he says. He can move the machine’s knee up and down, manipulating the W axis without changing the zero setting. The G2 control compensates for that, and nothing needs to be reset, he says. The control also uses Acu-Rite Senc 150 1-micron (0.00005-inch) linear encoders for positioning and feedback.

“I can now do more lines on a horizontal, vertical or an angle; arcs; and pockets than before,” Mr. Kubin says. “I am currently working on a project that requires quite a few mating pieces that have very specific arcs. I would never have been able to prototype this with this current level of accuracy before.”

Another key feature of the control is a circle function, which he uses to make certain pockets. “This function allows me to not have to have a drill bit or an end mill, and I still can get the pocket done, since I can easily make a box come up,” he says.

Mr. Kubin adds that the G2’s tool probe and the ease with which he can view and change the program have helped him create detailed prototypes quickly. For example, he can now touch off his part and calculate where the datum will be right on the control. He also says that he can easily look at the program and make modifications, incorporating all the ideas in his head.

Mr. Kubin says that the milling machine and control have enabled him to create a lineup of tattoo machines that blows everything else out of the water.

“I’ve really been able to hone in and precisely cut out exactly what I want. And when I mess up, I can just change my program a little bit and start over easily,” he says.

Mr. Kubin still uses a local machine shop for mass production, but the quickness and ease with which he can create prototypes has saved both time and money. “I’d say my new machine has made its money back 10 times over,” he says.

He often brings his machines to the tattoo studio and tries them out on willing customers. “Part of tattooing for me is strong product development. You really don’t know what a machine is going to do until you put the needle to the skin,” he says. “A lot of my success is due to my wonderful and willing customers.”

Mr. Albeitz adds, “Although Dan did not invent the rotary tattoo machine, he has developed the business of designing and producing them as a true art form. As one might expect, AMS does not normally deal with anyone in this particular line of work, but with the Acu-Rite MillPwr G2 married to the right machine tool, just about anything is possible.”

Dan Kubin used to prototype his distinctive rotary tattoo machines using hobbyist-type equipment, but the process was too slow to keep up with his creativity and the demand for his products.

Mr. Kubin purchased a new mill with an Acu-Rite MillPwr G2 control, which reduced the time required to make a prototype from a day and a half to half a day.


Mr. Kubin says that the Acu-Rite MillPwr G2 control has not only increased the speed of his prototyping process, but it has also enabled him to add more detail to his tattoo machines.
