Products

• BRILLANT 230: Cut-off Machine: Wet abrasive cut-off machine with manual wheel feed for sectioning metallographic samples up to 110 mm diameter. The aluminium body has openings on both sides so long parts can be passed through the cutting chamber, and the chamber itself is large enough for a range of clamping arrangements.
• Qcut 250 M: Cut-off Machine: Manual wet abrasive cutting machine in which the hood folds inwards on opening, leaving the whole cutting chamber accessible. A round window gives a clear view of the cut in progress. It takes wheels up to 250 mm and samples up to 90 mm diameter for short lengths.
• Qcut 250 A: Cut-off Machine: Semi-automatic abrasive cut-off machine with an automatic X axis, so it can perform pulsed cuts and oscillation cutting on large pieces as well as manual traverse cuts by hand wheel. An optional automatic cross table allows serial cutting, and the axes are monitored by travel measurement during setup and operation.
• Qcut 350 A: Cut-off Machine: Automatic wet abrasive cut-off machine for samples up to 135 mm diameter, with a low contact cutting function that reduces the thermal load on the specimen. Software features include automatic touch detection and multi-position processing, and it is used on composites and electronic assemblies as well as metals.
• Qcut 500 A: Large Cut-off Machine: Floor standing automatic cut-off machine for large components up to 190 mm diameter, with a highly dynamic axis drive and automatic traverse and chop cut functions. Feed rate is adjustable across a wide range so contact pressure can be tuned to the material.
• Qcut 600 A: Large Cut-off Machine: The largest cut-off machine in the QATM range, taking wheels up to 600 mm and workpieces up to 244 mm diameter. Automatic travel and cross feed allow low contact cutting of heavy components without repositioning by hand, and the working chamber is sized for the parts that come with that capacity.
• Qcut 200 A: Precision Cut-off Machine: Precision cut-off machine with up to three automatic axes for sectioning small and delicate samples where kerf position matters to a few micrometres. Cross feed resolution is 0.001 mm, which suits electronic components, coatings and thin sections rather than bulk metallography.
• Qtool Series: Quick Clamping Tools: Quick clamping tools that hold the specimen securely on the cutting table without slow screw adjustment between samples. Correct clamping is what prevents the specimen shifting mid cut, which would damage the wheel and ruin the section, so it is a functional part of the cutting process rather than an accessory.
• Qpress 40: Hot Mounting Press: Fully hydraulic hot mounting press with water cooling, embedding metallographic specimens in thermosetting resin. Heating and cooling times, temperature and pressure are set on an industrial touchscreen, and mould cylinders are available in several round and rectangular sizes. Advanced software adds one button operation and controlled fine dust extraction.
• Qpress 50: Hot Mounting Press: Hot mounting press in the same fully hydraulic, water cooled family as the Qpress 40, sized for the larger mould diameters. It uses the same closure system, which is designed so the mould assembly opens and closes cleanly over long service.
• Qmount: UV Mounting Device: Ultraviolet curing mounting device that sets the embedding resin with UV light instead of heat and pressure. Because there is no thermal cycle, it suits specimens that would be altered by hot mounting, and cure times are short compared with conventional cold mounting resins.
• Qpol M1 / M2: Manual Grinding and Polishing Machine: Manual single wheel (M1) and twin wheel (M2) grinding and polishing machines for laboratories preparing specimens by hand. They accept the Qpol GO head as a retrofit, so a laboratory can start manual and add semi-automatic preparation later without replacing the base machine.
• Qpol GO: Grinding and Polishing Head: Grinding and polishing head that converts a manual Qpol machine into a semi-automatic one. Single pressure and preparation time are set with rotary controls on the head itself, and the working area is lit and left visible by the slim housing.
• Qpol GO 1 / GO 2: Grinding and Polishing Machine: Automatic single wheel (GO 1) and twin wheel (GO 2) grinding and polishing machines that can run in single pressure or central pressure mode. Single pressure loads each specimen individually, which suits mixed hardness samples; central pressure loads the whole holder, which is faster for identical specimens.
• Qpol PLUS 1 / PLUS 2: Grinding and Polishing Machine: Automatic single wheel (PLUS 1) and twin wheel (PLUS 2) grinding and polishing machines with a higher performance head than the GO series, taking sample holders up to 185 mm diameter in central pressure mode. Specimens up to 50 mm diameter can be prepared, six at a time under single pressure.
• Saphir 550 / Rubin 520: Grinding and Polishing Machine: Grinding and polishing machine pairing a Saphir 550 base unit with a Rubin 520 preparation head. The head carries the sample holder and applies the load while the base drives the working wheel, so head and base can be specified to suit the throughput a laboratory needs.
• Saphir 560 / Rubin 520: Grinding and Polishing Machine: Grinding and polishing machine combining a Saphir 560 base unit with a Rubin 520 preparation head, the larger base in the Saphir line. As with the 550 combination, the head applies specimen load and the base drives the working wheel under programmed control.
• Qpol XL: Grinding and Polishing Machine: Large format grinding and polishing machine taking 300 mm and 350 mm working wheels and sample holders from 159 mm to 204 mm diameter. Both wheel and holder speeds are variable, which allows the removal rate and surface finish to be set independently.
• Qpol Vibro: Vibratory Polisher: Vibratory polisher that produces specimen surfaces with almost no residual deformation, by letting the sample move under its own weight on a vibrating cloth rather than being pressed against it. That matters for electron backscatter diffraction, atomic force microscopy and nanoindentation, where a deformed layer would mask the result.
• Qgrind XL: Planar Grinding Machine: Automatic planar grinding machine for the first, heavy removal step in specimen preparation. A ForceControl function measures removal electronically so the depth ground away is reproducible, and different grinding modes let the machine be set for maximum removal or for surface quality.
• Qetch 100 M: Electrolytic Polishing and Etching Machine: Manual electrolytic polisher and etcher that removes material by anodic dissolution rather than abrasion, giving a deformation free surface on metals that smear or work harden under mechanical polishing. The same unit performs electrolytic etching to reveal the microstructure.
• Qetch 1000: Electrolytic Polishing and Etching Machine: Electrolytic polishing and etching machine with programmable parameter control, so voltage, current and time can be stored per material and recalled. It covers the same anodic dissolution process as the Qetch 100 M with the reproducibility that stored settings give.
• Qness 10 / 60 M: Micro Hardness Tester: Manual micro hardness tester covering Vickers, Knoop and Brinell, with Rockwell as an option. Force is applied electronically and the test sequence runs automatically once the indent position is set. An eight position motorised turret carries up to three testing modules and seven lenses, so the tester doubles as a metallurgical microscope.
• Qness 10 / 60 A+: Micro Hardness Tester: Fully automatic micro hardness tester with a motorised XY cross slide, so hardness traverses and case depth profiles run without operator intervention. Positioning accuracy is 2 micrometres and the table travel can be extended to 300 by 150 mm for larger specimens.
• Qness 60 A+ EVO: Micro Hardness Tester: The EVO generation of the automatic micro hardness tester, with positioning accuracy improved to 0.2 micrometres. That resolution matters for closely spaced indent series such as case hardening depth measurements, where indent spacing rules limit how near indents may be placed.
• Qness 150 CS: Rockwell Hardness Tester: Compact Rockwell hardness tester with a C shaped frame, a fixed test head and a spindle that raises the specimen to the indenter. Force is applied electronically and the sequence runs automatically, with results shown on a 7 inch touchscreen. It complies with DIN EN ISO 6508 and ASTM E-18.
• Qness 150 CSA+: Rockwell Hardness Tester: Rockwell hardness tester with a fully automatic XY slide, combining the speed of a dedicated Rockwell machine with automated series testing. It suits parts of identical test height where a defined pattern of indents is required, and single tests can still be run manually.
• Qness 60 / 150 RCS: Rockwell Hardness Tester: Production line Rockwell hardness tester with a test cycle under two seconds, controlled by a Siemens S7 with a 4 inch touch display. It is built to be integrated into a production line for in-process hardness checking, with results output over an RS232 interface.
• Qness 200 CS: Macro Hardness Tester: Compact universal macro hardness tester with a five position turret carrying indenters and lenses. The fixed head and moving spindle arrangement gives a 250 mm test height with a 238 mm throat, so reasonably large parts can be tested without a special fixture.
• Qness 250 / 750 / 3000 C and CS EVO: Universal Hardness Tester: Universal hardness testers covering Brinell, Vickers, Rockwell, Knoop and plastics methods, in three force classes up to 3000 kg. The C shaped frame with fixed head and moving spindle gives a 395 mm test height, and an eight position tool changer is available in place of the standard two positions.
• Qness 250 / 750 / 3000 E EVO: Macro Hardness Tester: Macro hardness testers with an extra large fixed test table and a motorised test head, so very large components can be tested without lifting them onto a spindle. Test height reaches 510 mm and the table measures 584 by 450 mm, which puts heavy fabricated parts within reach.
• Qness 250 / 750 / 3000 A+ EVO: Fully Automated Macro Hardness Tester: Fully automated macro hardness testers with three axis control, so specimens of differing test height can be measured in one run without refixturing. A Jominy sample holder with test module is available as an option for end quench hardenability testing.
• System Laboratory: Metallographic Laboratory Furniture: Modular laboratory furniture designed around metallographic preparation, with work surfaces, framework, handles and high pressure laminate decor specified for the wet and abrasive conditions of a sample preparation room. QATM provide 3D planning software so a layout can be reviewed before it is built.
• Qeye 200 / Qeye 800: Optical Analyser and Inverse Macroscope: Inverse macroscopes for visual quality control of weld seams, solder joints and components, working directly on the macro section. The Qeye 200 has the finer field of view for laser welds and electronic assemblies; the Qeye 800 covers the larger fields used for macro welds in steel fabrication. Both assess weld shape, penetration depth and defects to DIN EN ISO 5817.
• Qpix T2 and Qpix Control2: Hardness Testing Software: Software for QATM hardness testers, from Qpix T2 on the touchscreen models through Qpix Control2 for automated testing and the Control2 M and R variants that add microscopy and reporting functions. It handles test sequence definition, indent evaluation, series and traverse programmes and result documentation.
• Q AI: Automatic Indent Evaluation Software: Machine learning module that evaluates hardness indents automatically, including the difficult surfaces where conventional edge detection struggles. It runs inside the Qpix environment and is aimed at removing operator to operator variation in reading indent diagonals.
