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.

In the fully automatic mode (Smartgrind), the grinding process is continuously evaluated and the grinding requirement of the stone is automatically determined and efficiently controlled. Stones may also be dressed at predetermined intervals as well as manually. The remaining stone height, the wear of the dressing diamond and the process flow are shown dynamically on the display.

When planar grinding metallographic samples, both high removal rates and flat samples with high surface quality are the goals. In the „roughing“ grinding mode, material removal can be increased by up to 20% compared to conventional processes, thus significantly reducing process times. In „Finishing“ mode the surface quality is improved by up to 15%. The combination of different modes produces optimal grinding results with maximum efficiency.

The QATM Qgrind 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.

High-quality aluminum oxide or silicon carbide grinding stones are available for the various applications. Synthetic resin-bonded diamond grinding wheels can be used for planar grinding ceramic materials and hard metals. The grinding media, specially optimized for materialographic grinding processes, are designed for high removal rates, surface qualities and flatness. The QATM grinding media are approved for rotational speeds of up to 2000 rpm as standard.

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 basic requirements when developing the automatic grinder Qgrind XL were a corpus and polishing head of utmost stability. These requirements form the basis for a low-vibration and robust grinding process. 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.

A 4 kW drive motor drives the grinding stone of the Qgrind XL and ensures high material removal and rotational speeds of up to 2000 rpm. The sample holder is driven in the grinding head with up to 1.1 kW, which means that grinding forces of up to 750 N can be achieved. The speed of both systems can be variably controlled.

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 modern design of the proven QATM control software enables intuitive and user-friendly operation. All process parameters are clearly displayed and can be easily set by touch. The grinding process is continuously monitored and graphically displayed using the SmartGrind software function.

A circulation cooling tank can be seamlessly integrated into the machine base and is easily accessible via push-to-open door. Lateral guidance of the extendible and rollable unit via slide rails. During the grinding process, the flow and temperature of the coolant are monitored in the software. Depending on the application, different circulation cooling systems can be used with the Qgrind XL.

The tool compartment integrated in the machine housing is particularly practical. This means you always have easy access to all tools.

An integrated rinsing hose allows for manual cleaning of the working area.

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.

Direct suction of vapor from the working area through suction nozzle.

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.
