Ships in 1–2 business days
Spec-match guarantee on every lot
Built for production teams
What your process engineer actually checks
Locked, traceable lot chemistry
Every lot ships with a COA documenting PSD, sphericity, flow rate, apparent density, and full chemistry — and a lot number you can trace. Aerospace and medical teams reorder 4+ times without re-qualifying.
Qualified parameters, not just powder
Validated parameter sets for EOS M 290, Renishaw 500Q, SLM 280, and our own AO Metal LPBF ship with the order. Load the profile and hit density on the first build — no parameter-development burn.
A materials engineer on the line
Questions on ferrite content, flowability, recyclate ratios, or HIP response? A materials engineer answers directly — not a contact-form bot. Most replies in under 4 hours, NDA standard.

FEATURES
The basic requirements when developing the automatic grinder / polisher Qpol XL were a corpus and polishing head of utmost stability. A solid steel construction, powder-coated and a working area lined with stainless steel emphasize the sustainable, and at the same time modern and compact, machine design – made in Germany.
The QATM Qpol XL comes with a system for precise measurement of material removal – regardless of operating time, sample type, material and hardness, you can easily monitor the material height already removed.
The drive motor of the working wheel has a power of 2.2 kW and the polishing head of 1.1 kW. The speed of both systems can be operated in clockwise and counter clockwise direction as well as in oscillating movement.
Electronic measurement system for controlled press forces between 50 and 750 N.
Integrated removal measurement
Intuitive operating software
Modular dosing concept with level warning
In the cleaning station specimens are automatically cleaned with water, ethanol and air and by spin cycling at up to 800 rpm (adjustable). Thus, each preparation step is finalized with a cleaning step.

QATM offers a wide selection of standard sample holders with different diameters and for a variety of applications and machines. Clamping of samples with unusual dimensions can be realized with special sample holders.
The fully loaded motorized swivelling dosing arm provides uniform wetting of the working wheel. It offers automatic referencing, automatic nozzle rinsing as well as good accessibility to the dosing hoses.
Direct suction of vapor from the working area through suction nozzle.
The motorized acryl glass safety hood protects the working area of the machine. The transparent hood is equipped with a safety switch and opens automatically when the program is finished. For easy cleaning the hood can simply be unhinged.
The cleverly integrated dosing system accommodates up to 6 Qdoser Duran glass bottles (1L). When equipping the Qpol XL with “Preparation Dosing System”, the suspension containers can be retrofitted in packages of 2, preparing your Qpol for all future requirements. Details like the gentle illumination of the containers and the soft-closing hood top off this well-thoughtout equipment option.

Integrated spiral rinsing hose with ball valve allows for manual cleaning of the working area.
The dosing system can be equipped with a magnetic stirrer. The automated stirring ensures optimum distribution of abrasive particles contained in the suspension before usage. This homogenization process significantly improves the preparation result. The new level detection for suspensions gives a warning before the container is empty, which is refillable in the ongoing process.
The spin cycle function „Cleaning Boost” is integrated into the software and spins the residual liquid off the grinding/polishing medium at the end of the preparation process with max. rpm for 3 seconds.
The optional signal lamp allows monitoring of your Qgrind XL from a distance: The red/yellow/green lights show the current state of the machine at a glance.
Seamlessly incorporated into the machine base and easily accessible via push-to-open door. Lateral guidance of the extendible and rollable unit via slide rails.

Unedited feedback from customers who reorder QPOL XL.
★★★★★
Same lot 4 times in a row. We stopped re-running parameter sweeps after the second order — density was identical to the first build.

Asked about ferrite content on a Friday. A materials engineer answered Monday morning with actual data, not a sales pitch. That's why we keep ordering.

COA matches the bottle. PSD and flow are exactly what was on the sheet — we run it on a Renishaw 500Q and it hits density on the first try.
