1、 Integrated cutting and grinding machine for petrographic samples

     For more than half a century, MetLab has provided various professional equipment for material research fields such as Metallography, Petrography and biomedicine. The primary focus of petrographic analysis is the preparation of rock and mineral sample slices, grinding and thinning. The METCUT-10GEO integrated lithofacies precision cutting and grinding machine provided by MetLab is a proven classic tool.

●Cutting and grinding, one machine is coaxial, and the diameter of the shaft is 1.25 inches (31.75mm), ensuring a high degree of parallelism during the transfer process of cutting and grinding for the same sample, without worrying about the plane positioning of the sample. When grinding and thinning the thin film after cutting, there will be no phenomenon of grinding deviation. One machine has two functions, and its cost-effectiveness is very outstanding.

●The motor speed is continuously adjustable from 100-3000rpm/min in increments of 1rpm/min. High rotational speed means fast cutting speed and high work efficiency when cutting raw stones; Lowering the speed means higher adaptability, controllability, and safety when cutting or grinding thinner sheets or porous and fragile materials.

●Both warehouse doors (protective covers) are opened upwards, without occupying any left or right space. This not only saves the laboratory's floor space, but also frees up the operating space. Upper and lower diamond cutting blades and diamond cup shaped grinding wheels, micrometers (micrometers) on the upper and lower grinding handle sides, glass slides bonded to the samples, cleaning and cutting chambers, and grinding chambers&hellip& Hellip; Wait a minute, the operating space is sufficient, and the safety and convenience are very high.

●Importantly, both warehouse doors have magnetic safety interlocks&# 8217& Flash; The motor cannot run without closing the compartment door; The motor does not stop running and cannot open the compartment door. The safety of the operator is guaranteed with certainty.

●The sample clamping is all adsorbed by a vacuum chuck, simplifying the loading and sampling operations, and the loading instructions are clear with the vacuum chuck as the positioning.

●The vacuum chuck on the cutting side is installed on the chuck fixing seat on the workbench; The vacuum chuck on the grinding side is installed on the coaxial inner arm of the grinding operation handle.

●The two air pipes of the independent vacuum pump are respectively connected to the vacuum chuck on the cutting side and the grinding side.

●LCD touch screen control panel, no cumbersome settings&ndash& Flash; Simply set the rotational speed and perform vacuum on/off, cooling water on/off, cutting or grinding on/off&flash& Flash; Avenue to Jane.

●Both cutting and grinding are manually operated, which greatly increases the range of materials that can be prepared, while giving users full freedom of operation. Different samples, preparation requirements, and observation purposes can be processed as needed.

●During the cutting operation, the positioning of the cutting thickness (X-axis transverse) is adjusted by the micrometer knob, with a feed rate of 0.005mm per scale. The total travel distance is 20mm. After positioning, cut along the Y-axis (longitudinal) with the handwheel. The total stroke is 224mm, and the diamond cutting blade cuts the sample.

●Grinding operation, select 70 according to the removal amount μ M or 30 μ M's diamond cup shaped grinding wheel moves back and forth by holding the handle, and the end of the handle shaft is equipped with a micrometer to control the grinding feed. Friction between the diamond on the surface of the sample and the grinding wheel to achieve thinning.

●Diamond cutting blade with a diameter of 10 inches (254mm); The diameter of the diamond cup shaped grinding wheel is 10 inches (250mm), and the axial aperture is 1.25 inches (31.75mm).

●The cutting capacity is 60mm, and the cut sample can be as thin as 0.5mm (500 μ m) ; The ground sample can be as thin as 0.03mm (30 μ M)

2、 Lithographic sample bonding platform

     Whether it is cutting thin slices or subsequently grinding and thinning the cut slices, bonding the sample to the glass slide is an important condition for implementing vacuum chuck adsorption of the sample.

     Founded in 1968, MetLab provided a powerful assistant while launching the METCUT-10GEO integrated lithofacies precision cutting and grinding machine& Flash; Thin sample bonding table METBOND GEO.

●Eight samples can be bonded at once.

●Spring pressure can accurately control the average thickness of the adhesive, thereby solving the problem of sample and slide thickness tolerance.

●Equipped with heating function, 0-300 ℃, digital display, providing convenience for rapid curing.

If you choose a bonding table without a heating plate, cure at room temperature. The curing time is longer, but the cost will be saved.

3、 Vacuum chuck for petrographic samples

     MetLab's integrated lithofacies precision cutting and grinding machine METCUT-10GEO uses vacuum chucks for fixing samples on both the cutting and grinding sides. The vacuum comes from an independent vacuum system matched with METCUT-10GEO. Vacuum on/off is integrated on the touch screen control panel, and cutting and grinding are operated independently. The vacuum on/off of cutting is displayed in the second row of the touch screen; The vacuum on/off of grinding is displayed in the third row of the touch screen.

     When clicking to turn on the vacuum switch, align the sample slide with the vacuum chuck to adsorb and fix it. After cutting or grinding, turn off the motor and cooling water, open the compartment door, click on the vacuum switch on the touch screen, close the air circuit of the vacuum chuck, and then download the glass slide.

     METCUT-10GEO comes with a pair of large and small sized vacuum chucks, covering all standard glass slide sizes. The outer frame size of the vacuum chuck is the same, and the distinction between large and small is determined by the size of the sealing ring. The sealing ring size of small-sized vacuum chucks is 20mm wide and 40mm long. Commonly used glass slides, such as 27x46mm, 28x48mm, and 1x3in, can be used on small-sized vacuum chucks; The sealing ring size of large-sized vacuum chucks is 40mm wide and 66mm long. Commonly used glass slides, such as 1.5x3in, 2x2in, and 2x3in, are used for large-sized vacuum chucks.
