Maximum reproducibility

By minimizing the risk of human error, Xmatic significantly improves reproducibility. Setup is quick and simple, then Xmatic does the rest by automatically setting up parameters such as force. The result is greater reproducibility, less consumables waste, and optimized throughput, which means greater certainty.

Process standardization

Xmatic gives you full documentation data, including the number of specimen holders that it runs, methods used, consumables consumption, and operating times. This enables you to standardize your process for greater reproducibility and efficiency.

Higher throughput

Xmatic has rapid and simultaneous mechanical movements that reduce process time, including fast cleaning programs and up to 8 specimen holders that can be loaded at any time. Throughput is further increased by minimizing human error and potential rework.

Ease of use

Xmatic has been designed with simplicity, flexibility, and user wellbeing in mind. Featuring an intuitive user experience with ‘embodiment’, a new bottle concept with Easy connectors for fast, spillage-free consumable change, and multiple automated features that minimize the need for operator intervention, Xmatic is easy to set up and use with minimal training.

From loading the machine to finished specimen

It takes around 5 minutes for a lab technician to set up Xmatic with consumables and insert 8 specimen holders, all with their own method. Xmatic then does the rest – automatically – while the technician works on other tasks.

This video shows Xmatic performing the entire grinding and polishing process, including:

· High removal plane grinding and fine grinding
· Pre-dosing of preparation surfaces
· Polishing
· High pressure cleaning and spin drying between preparation steps
· Final cleaning and drying of specimens

  • Xmatic feature 1 lab space

    Optimize lab space

    Xmatic has been designed to minimize the floor space it requires, for example using a vertical conveyor to optimize its footprint. However, for labs where space is particularly limited, Xmatic also comes in a smaller model, Xmatic Compact, that does not include a high-speed plane grinding station. Instead, plane grinding can be done on a MD grinding and polishing station, with a speed up to 600 rpm.

    Optimize lab space
  • Xmatic feature 2 intuitive

    Intuitive user interface

    The entire user experience is simple and intuitive, requiring less training to operate. A redesigned user interface gives a complete representation of the machine, with a vertical conveyor to the left, consumables on the bottom, and cloths to the right (so-called ‘embodiment’).

    Intuitive user interface
  • Xmatic feature 3 consumable detection

    Automatic detection of consumables

    Codes on each consumable bottle or MD surface give Xmatic the data it needs, which eliminates entering incorrect information and saves time when setting up the system. Xmatic can also detect what µm size it has previously used on each MD polishing surface, which eliminates risks of contamination.

    Automatic detection of consumables
  • Xmatic feature 4 tube cleaning

    Automatic tube cleaning

    A special cleaning program for flushing the tubes means that Xmatic can help you to avoid contamination when changing suspension and lubricant. The machine can recognize if the tube has not been cleaned and will alert the operator if changing to a different µm size, without asking the system to clean.

    Automatic tube cleaning
  • Xmatic feature 5 dressing

    Dressing of MD grinding surfaces

    Xmatic is equipped with two dressers that fit different surfaces. The frequency can be set to keep the removal rate of a grinding surface. This means you do not need to supervise the surface performance or manually dress each surface.

    Dressing of MD grinding surfaces
  • Xmatic feature 6 cleaning

    Complete cleaning and drying

    Xmatic features different cleaning options. A high-pressure cleaning system with optimal nozzle positioning and improved water pressure. Ultrasonic cleaning is also an option. Drying is done by spinning the specimen holder leaving you with perfectly clean and dry specimens.

    Complete cleaning and drying
  • Xmatic feature 7 pre-cleaning


    A pre-clean step can be added for specimens prepared with e.g. oil-based suspension/lubricants using a dedicated MD-Nap cloth adding soap and water.

  • Xmatic feature 8 method filter

    Easy filtering of methods

    An improved filtering functionality makes it easy to find and select a method in Struers’ vast method database.

    Easy filtering of methods
  • Xmatic feature 9 2 methods

    2 sets of methods

    Two separate sets of Struers methods are available. One set of methods for Xmatic includes a high removal grinding station and one set of methods for Xmatic Compact that does not include a high removal grinding station.

    2 sets of methods
  • Xmatic feature 10 inspect

    Inspect functionality

    Xmatic allows you to stop the process at any given stage to inspect your specimens. When returning the specimen holder to the vertical conveyor, the machine will ask if it should continue from the process step it stopped or start from the beginning.

    Inspect functionality
  • Xmatic feature 11 step selection

    Step selection

    Xmatic enables you to choose which steps to run in a method to give you full flexibility. Just choose which steps you want to run.

    Step selection
  • Xmatic feature 12 dosing

    Accurate dosing pumps

    Xmatic features a new type of pump system that is controlled in very small and precise steps, no matter the viscosity of the fluid. This ensures your process is reproducible, with no dosing variation.

    Accurate dosing pumps
  • Xmatic feature 13 capacity

    High capacity on disc and in specimen holder

    Xmatic is compatible with disc sizes either 250 or 300 mm dia. and specimen holders either 140 or 160 mm dia. A larger disc size gives you a larger preparation area and supports the processing of larger specimens.

    High capacity on disc and in specimen holder
  • Xmatic feature 14 closed chamber

    Closed chamber

    Everything is housed within a closed chamber, which means there is less human interaction and less risk to health and safety. This helps workers to feel more comfortable in the lab environment, reducing absenteeism.

    Closed chamber
  • Force

    Force adjustment according to number of specimens

    Xmatic can automatically adjust the force in the method according to the number of specimens in the specimen holder. This eliminates the need for you to calculate the force yourself. It also reduces the number of methods required in the method database. Just select the number of specimens in the specimen holder by clicking on the icon.

    Force adjustment according to number of specimens
  • Xmatic feature 16 data reporting

    Data reporting

    Xmatic creates log files that can help you verify and improve the process, store records, and monitor for maintenance. The machine registers the number of specimen holders, the methods and consumables used, and more.

    Data reporting
  • Xmatic feature 17 cloth run in

    Automatic cloth run-in

    Xmatic performs an automatic run-in process for new polishing surfaces to check whether pre-dosing should happen prior to starting. This removes the need for human attention when running in a new polishing cloth.

    Automatic cloth run-in
  • Xmatic feature 18 8 specimen holders

    Load up to 8 specimen holders

    You can load up to 8 specimen holders at a time and allocate the same or different methods to each specimen holder. The order they should be processed is selected by clicking on the icons.

    Load up to 8 specimen holders
  • Xmatic feature 19 change of consumables

    Changing suspension and lubricant

    When a consumable is inserted, Xmatic automatically recognizes the consumable by a unique data matrix code. If you run out of suspension or lubricant, you can change to a new bottle containing the same without cleaning the tubes. If you change to a different suspension or lubricant without asking to clean the tubes, Xmatic warns you and asks you to clean the tube or proceed without cleaning.

    Changing suspension and lubricant


Model types

Xmatic is available in two variations, see specifications for details.
