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 leave no gaps in accountability.
From requirements definition through 3D modeling and structural review. We bake manufacturability (DFM) into the design stage, cutting revision cost and trial-and-error after prototyping.
An in-house line built on simultaneous 5-axis machining centers and CNC turn-mill. We hold drawing tolerances on complex geometry and certify quality on a granite surface plate.
Sensors, motor control, firmware, and communications — developed in parallel with the mechanical design. Integrated mechatronics eliminates interference and errors before assembly ever happens.
Every hand-off between vendors breaks the flow, and 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 — quantity is never a wall.
Small batches and volume runs alike are handled 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 — house brands we plan, build, sell, and stand behind with everything we have.
DAFF is a components brand built for professional cyclists. Chainrings, cogs, and chain catchers proven on keirin and velodrome tracks, machined in-house on simultaneous 5-axis equipment. At the moment of truth — You Never Turn Alone.
Tooth-profile design — it starts with 3D CAD curves

AUFF is a high-end audio brand. From the 3-axis tonearm base, stabilizer, and precision level to amplifiers, DI boxes, power distributors, and audio racks — precision engineered in the service of sound.
Welcome a new tonearm without a single millimeter of damage to your treasured plinth. Three precision slides put overhang and effective length exactly where you want them — preserving the original while unlocking the ultimate tuning.
Set overhang precisely where it belongs
Fine-tune effective length — dovetail slide
Beyond mechanical limits to VTA & SRA
Package components — incl. optional add-ons
Zero-damage plinth mount — 3-way RCA terminals

DAFF and AUFF are living proof that PK'SOLUTION carries the whole journey. A spec sheet is only the minimum — our standard always sits above it. Your project is held to the same standard.
Same spec sheet, different result. The reason is simple — it's PK'SOLUTION.
The equipment that makes the difference, and the record built together with our customers.

PK'SOLUTION is a development company that carries 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.
Because what we align to is not the drawing — it's our customers' happiness.
From a single prototype quote to a full production run, we'd love to hear from you.
