Frame-mounted removable vacuum modules let one concrete grinder collect slurry or dust without separate hoses, simplifying cleanup.
Direct suction holding replaces tape on warped, raised-center plates while staged grinding reduces reaction force and produces even thickness.
A partitioned chuck table uses tailored curvature to balance grinding forces and improve thickness uniformity across polygonal workpieces.
Outer rotary disks rotate around a central disk to flatten solidified cement, eliminating uneven surfaces and additional tool costs.
Sealing the drive mechanism from debris protects bearings while lateral oscillation maintains continuous contact for efficient spring end flattening.
Grinding wheel moves concurrently along two directions to form a recessed portion of predetermined depth on the wafer back surface.
Powered alignment adjustment system moves grind spindle to submicron precision using a dual-threaded differential screw mechanism.
Concave grinding with an unevenness-absorbing pad prevents front-surface irregularity transfer while the annular reinforcing portion increases die strength.
A machining device uses a swivel arm and pressing unit to move a cutting disc across surfaces for remote operation.
A machining device supports construction elements on fixed tables to machine lower and upper faces simultaneously.
Dry grinding removes deep scratches without liquid staining or optical distortion, using temperature monitoring and cerium oxide polishing.
Integrated dressing unit on a rotary table enables in-situ tool maintenance without removal.
Adjustable guiding plates connect work holding and guiding lines to prevent inclination and facility stops during horizontal double disc surface grinding.
Orbital spindle movement eliminates reversal pauses in stone slab grinding machines, preventing shadow zones and ensuring uniform surface finish.
