We frame the skeleton with 3D design, shape the body with simultaneous 5‑axis machining, and set the heart beating with electronic control. From raw idea to finished product, it all happens inside one factory.
A thing born of a single idea, carried unbroken from first sketch to final cut.
That is what we call a work of craft.
Industry divided the process in the name of efficiency, and somewhere between those divided hands, the single idea was scattered. Like tracing a river back to its source, PK'SOLUTION returns to the origin, where objects were works of craft, carrying simultaneous 5‑axis machines and electronic control in place of the potter's wheel.
And at the source, we understand:
design, machining, and control were always one.
Design here, machining there, control somewhere else. That was the only way to build, and discord grew in the gaps. PK'SOLUTION completes all three as a single idea from the start. That is why we are fast, precise, and accountable from end to end.
From requirements definition through 3D modeling and structural review. We bake manufacturability (DFM) into the design stage, cutting revision costs and trial and error after prototyping.
An in‑house line built on simultaneous 5‑axis machining centers and a CNC turn‑mill. We hold drawing tolerances on complex geometry and verify quality on a granite surface plate.
Sensors, motor control, firmware, and communications are developed in parallel with the mechanical design. Integrated mechatronics catches interference and errors before assembly.
Every hand‑off between vendors breaks the flow; time and quality leak through the cracks. Inside this factory, the entire journey moves as one breath.

One‑off to full volume
From a single prototype to full production, volume is never a barrier.
We handle small batches and volume runs alike on our own equipment. The quality proven in development scales straight into production.
DAFF and AUFF are more than product lines. Design capability, precision machining, and finished‑product experience. We put all of it into house brands that we plan, build, sell, and stand behind.
DAFF is a components brand built for professional cyclists. Its chainrings, cogs, and chain catchers are proven in keirin and velodrome racing, and machined in‑house on simultaneous 5‑axis equipment. At the moment of truth: You Never Turn Alone.

SMART INNOVATION FOR SOUND SYSTEMS
AUFF is a high‑end audio brand. From 3‑axis tonearm bases, stabilizers, and precision levels to amplifiers, DI boxes, power distributors, and audio racks. We design and machine every piece ourselves, in the service of sound.
Welcome a new tonearm without drilling a single hole in your treasured plinth. Three precision slides put overhang and effective length exactly where you want them, preserving the original while letting you push the tuning as far as you want.
Set overhang precisely where it belongs
Fine‑tune effective length · dovetail slide
Take VTA & SRA beyond mechanical limits
Package components · incl. optional add‑ons
Zero‑damage plinth mount · 3‑way RCA terminals

3SB‑2 SilverMachining to a drawing you were given is one thing. Owning a finished product (planning, design, machining, control, and sales) is another thing entirely. DAFF and AUFF prove that PK'SOLUTION can carry a product the whole way. A spec sheet is only the minimum. We always aim above it. Your project is held to the same standard.
M-Link is FTP software built for automated machines (CNC · MCT). Times have changed, so why are shop-floor systems still stuck ten years in the past? That question, raised on our own shop floor, is where it began. The first answer: handling the programs of many machines in a single window. We made it free, for the engineers who work in the same conditions we do.
Today it covers the MCT data-server function. Next come a CNC server mode and an in-house team messenger, on the way to an integrated solution that brings ideas and manufacturing together in a single view. New versions are published here first, so check back often for the latest M-Link.

PK'SOLUTION is a development company that brings mechanical design, product development, precision machining, and electronic control under one roof, so customers never have to shuttle between vendors to get a product made.
A certified venture company holding multiple patents, we have partnered on work that demands precision and trust: research jigs for Samsung SDI, specialty cinema rigs for Cinedrone. And with that same capability, we build the brands that carry our own name: DAFF and AUFF.
We don't just match the drawing. We match what you actually need.
Whether it is a quote for a single prototype or a full production run, we'd love to hear from you.
