Garnet evaluation and appreciation

Garnet in color, transparency, clarity, weight and other aspects of its cut quality evaluation standards, excellent product requires pure color beautiful, clean and transparent interior, flawless crack, cut well and have some weight.
(1) Color: The color to be pure and beautiful. Different varieties, different colors, values ??are different. As rare demantoid, chrome vanadium grossular other green varieties if transparent without cracking, high quality and high quality emerald may equal value; red pyrope, orange spessartine, Hessonite also valuable, and maroon, dark red almandine lower value.
(2) Transparency: high quality person should be transparent and clean. Translucent or color depth are often processed into a concave arc in order to increase transparency. While opaque to translucent varieties to check the internal arrangement of inclusions see if processed into cabochon while showing a starlight effect.
(3) Clarity: To no cracks, flaws, especially a lot of dark red almandine. Complete crystal partakers who pay attention to whether the internal structure or folder with black opaque inclusions agglomerate. Such as Vietnam output intact skin only to garnet crystal thin transparent can be utilized for other mineral impurities within the black heart. At present, high-quality garnet mostly irregular silicon carbide grit.
(4) Weight: raw block the bigger the better, rounded shapes to mix better, which can improve the processing yield. Right Demantoid green grossular other high-grade varieties, the price increases exponentially with the weight, usually more than 0.5ct very valuable; while other species with different weight finished their prices changed little, mainly to see required when making jewelry styles and sizes requirements. But a few rare giant crystal or finished products can be regarded as treasures. (5) Cut: To fashionable, proper proportion, polish well. Different varieties of materials to be designed for different styles. High dispersion Demantoid processed into standard round brilliant, in order to fully reflect its fire color; coloration were processed for the double curved to enhance the body color; color depth are processed in order to lighten the color of the concave arc, increasing transparency; has multiple sets of special needles arranged in the direction of the arc-shaped inclusions processing to display the star effect.

Green silicon carbide wheel installation Precautions

Must first install the wheel safety and quality testing, method, Nepalese cashmere hammer (you can use a pen) tapping the side wheel, then no problem crisp sound. Positioning grinders installed in any location, is our first installation process Issues to consider only selected reasonable and appropriate location, we can carry out other tasks.
Grinder prohibit installed facing the operator or near the equipment and the past was often the place, generally the larger wheel workshop should set up a dedicated room. If indeed due to topographical constraints plant can not set up a dedicated wheel room, front wheel drive should be installed no less than 1.8m high protective baffle and baffle requires strong effective. Wheel balance wheel imbalance mainly by manufacturing and installation inaccuracies, the wheel rotation axis does not coincide with the center of gravity caused.
The harm caused by imbalance mainly manifested in two aspects, one in the wheel rotates at high speed, causing vibration, could easily lead to the workpiece surface polygonal oscillation marks; hand, accelerated the spindle unbalance vibration and bearing wear, serious will cause rupture of the wheel, and even cause accidents. Therefore, requiring great than or equal to 200mm straight sand loaded on the card office after hours should first conduct static balancing, wheel trimmed after shaping or imbalance found in the work, it should be repeated static balance. Matching matching problem mainly refers to the installation of the chuck and grinding wheel logistic problems. According to standards, wheel diameter not less than chuck is mounted sand office diameter of 1/3, and the corresponding provisions of the wheel wear to a diameter of 10mm diameter larger than the chuck should be replaced with a new wheel. So there is a chuck and grinding wheel matching problem, otherwise it will be the case, "big horse car" caused by equipment and material waste; "small horse cart" do not meet the safety requirements, could easily lead to accidents.
Therefore, chuck and grinding wheel reasonable match, one can save the device, cut about materials; hand and meet the safe operation requirements. Furthermore, the wheel should be installed between the chuck chuck diameter greater than the diameter 2mm, 1mm ~ 2mm thick cushion. Protective shield problem is the main grinding machine guards, whose role is: When damaged wheel at work for some reason, can effectively covering the wheel debris, to ensure the safety of personnel.
Grinding shield round and square shape, not exceed the maximum opening angle of 90 °; protective cover is made of a steel tensile strength of not less than 415N/mm2. Replaced with new wheel when the protective cover installed to solid and reliable, and shields do not disassemble or discard. Gear grinding machine quiet panel is one of the main protective accessories, protective cover above the horizontal plane of the spindle opening is larger than or equal to 30 (must be set for this device. Its main function is to block the grinding process to fly quiet, to avoid harming operator which is mounted on the open end of the shield, the width should be greater than the width of grinding wheel guard, and should be firmly fixed to the protective housing.
Furthermore, it requires the grinding wheel circumferential surface of the baffle gap should be less than 6mm. Bracket bracket problem is one of grinding machines commonly used accessories, according to the provisions above 150mm diameter wheel grinding machine must be set adjustable bracket. The distance between the wheel and bracket should be less than the minimum make-inch form grinding workpiece 1/2, but the maximum should not exceed 3mm. Grounding problem grinder using a power line, so the enclosure must have a good grounding protection devices. This is easily one of the important factors causing the accident.
