8Chew 8jaw polishing head grinding head polishing machine head

8-foot (8 grinding blocks/8 petals) polishing grinding head is the mainstream structure in stone grinding heads. 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.
1、 High polishing efficiency and more uniform surface
Full 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.
Faster 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.
Good flatness: 8 points of pressure dispersion, resulting in a flatter and less wavy surface, suitable for high-end mirror panels.
2、 Strong wear resistance and longer lifespan
Load 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.
Not 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.
Durable 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.
3、 Better adaptation between corners and surfaces
No 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.
Micro surface adaptive: floating structure+8-point support, even slight height differences/surface deformations can be smoothed out, suitable for matte (Lappato) and antique surfaces.
4、 High stability and low vibration
Excellent dynamic balance: 8-foot symmetrical distribution, less vibration during high-speed operation, low machine load, less likely to shake or break edges.
Uniform 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.
5、 Lower overall cost
Less frequency change: Long lifespan, reduced downtime for grinding head replacement, and higher production capacity.
Consumables saving: slow wear and tear per piece, low maintenance costs in the later stage, and more economical in the long run.
6、 Italian 8-Foot Grinding Head
More mature formula: metal/resin binder+high-precision diamond, wear-resistant, heat-resistant, and glossy transparent.
Precision craftsmanship: integrated molding with strict tolerances, better dynamic balance and concentricity, and more stable high-speed performance.
Suitable for all categories: marble, granite, quartz, rock slab, artificial stone, versatile in high gloss/matte/antique style.
