Automatic Grinder & Polisher

The QPOL 250 A1-ECO & QPOL 250 A2-ECO models are single and dual wheel grinding/polishing machines, respectively, suitable for any metallographic laboratory. They come with grinding wheels of Ø 200/250 mm and feature a user-friendly 4.3" touchscreen. The new holder for the working wheel (single-disc design) enables metallographic sample preparation without carrier disc without compromising performance. The control software allows to edit and save up to 200 preparation methods, protected by a user account management. Pressure, speed and direction of rotation (head and working disc) are adjustable. A spin cycle function (Cleaning Boost) helps to spin dry the grinding and polishing medium at 750 rpm at the end of the preparation process within 3 seconds. These robust grinding and polishing machines can be combined with the Qdoser ECO or Qdoser ONE automatic dosing system, offering maximum flexibility for sample preparation and operating convenience.

• Up to 200 customized grinding/polishing programs/recipes can be stored in the software
• Easy cleaning of the grinding bowl by simply lifting the working wheel
• Variable speeds for the working wheel/disc and sample holding head
• Both the working wheel/disc and sample holding head can rotate clockwise and counterclockwise
• Impact-resistant plastic bowl
• Powder-coated aluminum housing
• LED lighting for easy visibility during metallographic sample preparation

The grinding/polishing machines SAPHIR 550 / RUBIN 520 & SAPHIR 560 / RUBIN 520 are modernly designed grinding machines featuring an innovative grinding and polishing head for working wheels Ø 250-300 mm. These machines come as single working wheel models (SAPHIR 550 / RUBIN 520) or dual wheel models (SAPHIR 560 / RUBIN 520) with the common feature of the automatic sample holding head RUBIN 520.

The RUBIN 520 head is equipped with an automatic protective cover, setting new standards in operational safety. It operates with both single and central pressure, features memory functionality, and offers the option for an integrated dosing system. Additionally, it has the unique capability for material removal measurement.

The height adjustment is motorized, and pneumatic clamping of the main units SAPHIR 550 & SAPHIR 560 meets the highest demands. The material removal height can be pre-set with an accuracy of 0.01 mm. The measurement of the removed material is performed automatically, and once the pre-set value is achieved, the machine automatically shuts down.

• Working wheel(s): Ø 200-300 mm
• Single/Central pressure: 6 x Ø 50 mm
• Programmable memory for repeatable results
• Automatic dosing system (optional) - 6 positions
• One working position with a single grinding wheel or two working positions with two grinding/polishing wheels respectively
• Single and central sample pressure
• Variable speeds of the grinding disc and automatic head
• Electronic control via touchscreen
• Polishing head with both clockwise and counterclockwise rotation
• Memory capability for lateral and height positioning
• Automatic front cover for maximum safety

The vibratory polishing device Qpol Vibro is designed for the preparation of specimen surfaces practically without deformation. This preparation method is especially suited for further characterizations like EBSD (electron backscatter diffraction), nano indentation using AFM (atomic force microscopy) or micro hardness testing. Due to the very gentle removal of material it is applicable especially for soft and ductile materials, like titanium-aluminum, pure copper and copper alloys, aluminum alloys, soft steel, and nickel-based alloys. Having a diameter of Ø=308mm, the large bowl provides sufficient space for polishing of a complete sample holder, large specimens or for the simultaneous polishing of up to 21 mounted specimens. The bowl is equipped with a double magnetic system. It allows to fix, remove and clean both the bowl or polishing cloth very quickly, without any tools or other fixings.

Polishing cloths suited for magnetic system with a diameter of 300mm or 305mm (12”) can be used.

The user interface is very intuitive and offers a lot of features supporting the operator.

• Depending on the mass of the inserted specimens the automatic frequency control selects the optimal vibrational frequency in the range from 60 to 120Hz. Manual adjustment is therefore not necessary.
• As almost indefinite polishing time can be chosen, the Qpol Vibro is equipped with the QATM Surface-Guard. It suppresses crystallization or corrosion of the polished surface in the absence of the operator after a preparation recipe has ended.
• Pre-installed preparation methods and consumables can be selected for various materials
• A pre-installed list of consumables can be edited and extended by the customer
• Up to 200 preparation methods can be saved

For achieving best working conditions the Qpol vibro is equipped with an exhaust connection plug, which can be connected to an external exhaust air system. Based on the vibration adsorbing construction the Qpol Vibro provides a low noise operation.

• Rapid changeable polishing bowl with magnetic system
• Surface-Guard: reduces crystallization and corrosion of the specimen surface
• Automatic frequency control from 60-120 Hz, e.g. for mass variation
• Intuitive user interface and touch screen
• Pre-installed preparation methods and consumable list
• Low-noise operation, almost indefinite polishing time without supervision
• Exhaust connection plug (exhaust connection for enhanced user-friendliness and safety)
• Up to 200 custom preparation methods can be saved
• Polishing bowl ø 308 mm (compatible with 300 mm or 305 mm (12") polishing cloths)
• Vibration frequency: 60 - 120 Hz
• Plugs: USB, Ethernet
