Built to Adapt, Engineered to Perform

FK One Adjust pushes machine engineering forward with patent-pending stroke adjustment technology and a fully reimagined, artist-driven build. 

Change your stroke on the fly in seconds—from 2.0mm to 5.0mm in 0.5mm increments. This is adaptability in motion, built directly into the frame, so you can have versatility with no limitations. FK One Adjust eliminates the need to juggle multiple machines or cams. Move from heavy packing to delicate detailing in one continuous workflow, with precision you can feel. 

This machine boasts real innovation that delivers: engineering evolution is at the heart of what makes FK One Adjust so great. The stroke adjustment system operates with mechanical precision, letting you fine-tune responsiveness mid-session without powering down—something no other adjustable stroke system allows. 

Designed with artists at every stage of development, this machine is an artist-first powerhouse. Every mechanical choice was made to deliver consistent torque, clean transfer, and stable performance across every style. 

An upgraded digital display keeps you in total control. View your output in volts or hertz—your choice. Hertz gives a true frequency readout of needle movement per second, offering the most accurate insight into performance possible. That’s engineered for full visibility and control. 

And because FK builds machines to outlast your schedule, the FK One Adjust is built to last Every component is tested for endurance and supported by FK’s global service network.
