Multi-Station Rotary Table Robotic Grinding System
4-Position Continuous Production For Sanitary Hardware Finishing
The DZ Multi-Station Rotary Table Robotic Grinding System revolutionizes production throughput for sanitary hardware components by integrating a precision 4-position rotary indexing table with dual FANUC grinding robots operating in coordinated parallel processing. This innovative configuration enables simultaneous loading, rough grinding, finish grinding, and unloading operations across four discrete stations, eliminating idle time inherent in single-station robotic cells.
The 1200mm diameter rotary table indexes between positions in under 1.5 seconds with 0.02mm repeatability, while pneumatic clamping at each station ensures rigid workpiece fixturing during grinding operations. Purpose-engineered for high-volume production of faucet bodies, valve housings, shower components, and bathroom accessory parts in brass, zamak, and stainless steel, this system delivers up to 4x productivity improvement compared to conventional single-robot cells.
Key Features
- 4-Position Rotary Indexing Table: Servo-driven 1200mm rotary table with hardened steel cam indexer provides four precisely positioned workstations. Each station accommodates interchangeable fixture plates with pneumatic clamping and part-presence sensing.
- Dual Robot Parallel Processing: Two FANUC M-10iD/12 robots work simultaneously at two grinding stations with coordinated scheduling ensuring zero idle time between table indexes for maximum throughput.
- Rapid Station Indexing: Servo-driven table achieves 90-degree index times of under 1.5 seconds with ±0.02mm positioning repeatability. Hardened steel shot-pin locking at each station maintains fixture position rigidity under full grinding forces up to 200N.
- Operator-Friendly Load and Unload: Station 1 features ergonomic part presentation at 850mm working height with dual-hand anti-tie-down cycle start buttons and light curtain protection for operator safety.
- Quick-Change Fixture System: Each station accepts modular fixture plates with standardized mounting interface, enabling complete production changeover between different part families in under 15 minutes.
- Integrated Part Cleaning: Station 4 incorporates automated air blow-off and vacuum cleaning that removes grinding debris from finished parts and fixture surfaces, ensuring consistent part cleanliness for downstream operations.

Applications
Brass faucet body producers utilize this system for complete surface grinding of cast faucet bodies, achieving cycle times of 15-20 seconds per part across rough grinding of parting lines and finish grinding of visible surfaces. Zamak die-cast handle manufacturers processing large-volume production runs benefit from the continuous flow configuration, with one operator managing loading while finished handles accumulate for downstream plating.
Shower component producers processing multiple part variants utilize the quick-change fixture system to switch between part families without extended downtime. Valve manufacturers processing brass and stainless steel ball valve bodies employ the dual-robot system to grind both body exterior and flange face surfaces in a single fixturing, eliminating multiple handling operations required in single-robot cells for complete component finishing.
Packaging & Quality Assurance
Each system undergoes complete assembly and testing at the factory including rotary table indexing accuracy verification, dual-robot collision avoidance testing, and sustained production runs processing 500 plus sample parts. The system is partially disassembled into major modules for international shipping in reinforced wooden crates with detailed assembly documentation and color-coded connection labeling.
DZ installation engineers perform complete system reassembly, alignment, and commissioning at the customer facility, followed by operator training on fixture changeover procedures. The 12-month warranty covers both robots, the rotary table mechanism, and all grinding equipment with optional quarterly preventive maintenance visits and productivity optimization support.
