Frequently asked questions

What makes the CNC HAMMER a “powerful” tattoo machine?

What tattoo styles is the CNC HAMMER best suited for?
The CNC HAMMER excels in bold and saturated styles, such as:American Traditional, Japanese Irezumi, Black & Gray realism with heavy contrast, Color realism and large solid color blocks. Its strong hit and efficient pigment delivery make it ideal for high-density work.
-
Can I use the CNC HAMMER for lining?
Yes. While many artists prefer 3.5mm or shorter strokes for lining, experienced artists can achieve clean, decisive lines with the CNC HAMMER thanks to its strong punch and stable performance. The key is controlling hand speed and pressure.
-
Are there any precautions when using the CNC HAMMER?
Yes. Avoid staying too long in one area to prevent overworking the skin. Use high-quality cartridges and inks, adjust voltage and hand speed according to skin type, and maintain good skin stretching to ensure smooth and even results.
