Compared with 4-pin\/6-pin, the core advantages are denser coverage, more uniform force, more stable luster, longer lifespan, and more accurate corners, especially suitable for large boards, rock boards, and high gloss batch lines.\u003cbr\u003e1、 High polishing efficiency and more uniform surface\u003cbr\u003eFull coverage at 8 o'clock: 8 grinding blocks simultaneously contact the surface of the board, with more grinding points per unit area and denser trajectories, no missed polishing, and no positive or negative surfaces.\u003cbr\u003eFaster light output: under the same conditions, it is 20% -30% faster than 6-pin, with one step from coarse to fine to bright, reducing rework.\u003cbr\u003eGood flatness: 8 points of pressure dispersion, resulting in a flatter and less wavy surface, suitable for high-end mirror panels.\u003cbr\u003e2、 Strong wear resistance and longer lifespan\u003cbr\u003eLoad dispersion: 8 grinding blocks share the pressure, resulting in low stress and slow wear on each block. The overall lifespan is 30% longer than 6 feet.\u003cbr\u003eNot easy to burn: with multiple contact points, fast heat dissipation, good high-temperature stability, continuous processing is not prone to blackening or loss of gloss.\u003cbr\u003eDurable and long-lasting: The diamond\/resin layer has a higher utilization rate, slow gloss decay in the later stage, and strong consistency in mass production.\u003cbr\u003e3、 Better adaptation between corners and surfaces\u003cbr\u003eNo blind spots on corners: divided into 8 equal parts, with high fitting of corners\/arcs, rounded corners and chamfers, and no jagged edges or collapsed edges.\u003cbr\u003eMicro surface adaptive: floating structure+8-point support, even slight height differences\/surface deformations can be smoothed out, suitable for matte (Lappato) and antique surfaces.\u003cbr\u003e4、 High stability and low vibration\u003cbr\u003eExcellent dynamic balance: 8-foot symmetrical distribution, less vibration during high-speed operation, low machine load, less likely to shake or break edges.\u003cbr\u003eUniform pressure: Independently apply pressure at 8 o'clock, suitable for both wide and narrow plates as well as soft and hard stones, eliminating the need for frequent pressure adjustments and making order changes more worry free.\u003cbr\u003e5、 Lower overall cost\u003cbr\u003eLess frequency change: Long lifespan, reduced downtime for grinding head replacement, and higher production capacity.\u003cbr\u003eConsumables saving: slow wear and tear per piece, low maintenance costs in the later stage, and more economical in the long run.\u003cbr\u003e6、 Italian 8-Foot Grinding Head\u003cbr\u003eMore mature formula: metal\/resin binder+high-precision diamond, wear-resistant, heat-resistant, and glossy transparent.\u003cbr\u003ePrecision craftsmanship: integrated molding with strict tolerances, better dynamic balance and concentricity, and more stable high-speed performance.\u003cbr\u003eSuitable for all categories: marble, granite, quartz, rock slab, artificial stone, versatile in high gloss\/matte\/antique style.\u003c\/p\u003e","brand":"Haiyu polishing head","offers":[{"title":"Default Title","offer_id":43742593286210,"sku":"8Chew polishing head","price":15000.0,"currency_code":"HKD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0681\/1792\/1858\/files\/3c4ebfd2c4428b2a8ddb7f249c1f5829_c59715be-ff6b-4348-8cf5-247f2edda59b.jpg?v=1778724530","url":"https:\/\/shop.zginternational.cn\/products\/8chew-8jaw-polishing-head-grinding-head-polishing-machine-head","provider":"Haiyu polishing head","version":"1.0","type":"link"}
