A coil tattoo machine is a traditional and widely used type of tattoo machine that operates using electromagnetic coils to move a needle group up and down. Here's a quick breakdown of its components and how it works:
?? Main Components:
Frame – The structure holding all parts together.
Coils – Usually two electromagnetic coils that create the magnetic force to drive the armature bar.
Armature Bar – A movable bar that is pulled down by the magnetic force, driving the attached needle into the skin.
Contact Screw – Adjusts the distance and controls how long the circuit stays open or closed.
Spring (Front & Rear) – Works with the coils and armature to control the machine's speed and force.
Tube & Grip – Where the needle and ink are held; the artist holds this part.
Needle – Moves in and out rapidly to deposit ink into the dermis.
?? How It Works:
When electricity flows through the coils, they become magnetized, pulling the armature bar down and causing the needle to move. This movement breaks the circuit at the contact point, demagnetizing the coils, and allowing the spring to snap the armature bar back into place—restarting the cycle rapidly (usually 50–100 times per second).
?? Types:
Liner – Runs faster and is tuned to create sharp, clean lines.
Shader – Runs slower and is tuned for shading and coloring.
