Product Description

‌Key Structural Components of CNC Grinding Machine for Ferrous Metal Foundry:‌

Base Frame‌: Serves as the foundation supporting all mechanical assemblies and operational loads.
‌Vertical Column Assembly‌:

Integrated with precision linear guides and ball screw mechanism for Z-axis movement
Components: Shangyin-brand guide rails/screws with NSK bearings
‌Multi-Axis Robotic Arm‌:

Three rotational axes (X/Y/C) with high-performance reducers (RV or harmonic type)
Technical specifications:Transmission ratio >120:1
Bi-directional positioning accuracy <2 arcmin
Efficiency >90% with extended service life
‌Dual-Spindle Grinding Head‌:

Large diamond wheel spindle (2000rpm max):Processes external parting lines and major gates/risers
Micro-spindle (24,000rpm max):Handles internal contours and tight radii
Performance metrics:Grinding speed: 3-5 m/min
Repeatability: ±0.1mm
Wheel lifespan: 800+ operating hours
‌Indexing Workstation‌:

Rotary table with pneumatic assist system
Features:Quick-change fixture system (<30s)
Anti-fatigue support for U-axis reducer
Positioning accuracy: 0.01°
‌Workholding System‌:

Lever-actuated clamping mechanism
Holding force: 2-5kN (adjustable)
‌CNC Control Unit‌:

Customized polishing software (Huazhong-based)
Teaching pendant with:Handwheel fine-tuning (0.001mm resolution)
Adaptive path planning algorithms
This configuration ensures high-precision grinding of ferrous castings with cycle time optimization and tool longevity. The modular design allows process flexibility between roughing (large spindle) and finishing (micro-spindle) operations.

Workpiece Processing Cycle:‌

‌Manual Loading‌:

Operator places raw workpiece at the clamping station on the rotary workbench
Start button is pressed to initiate automated cycle
‌Workpiece Transfer‌:

U-axis rotates 180° to position workpiece at robotic arm station
Robotic arm retrieves workpiece using programmed gripping sequence
‌Precision Grinding‌:

Arm transports workpiece to grinding wheel station
Automated polishing performed per CNC program parameters
‌Finished Part Handling‌:

Robotic arm returns polished workpiece to workbench clamp
Workbench rotates 180° back to operator station
‌Cycle Continuation‌:

Operator removes finished part
New blank workpiece is loaded
Process repeats with next start command
This closed-loop system enables continuous production with minimal manual intervention, maintaining consistent positioning accuracy (±0.05mm) throughout the transfer and grinding operations. The 180° rotation mechanism optimizes floor space utilization while ensuring ergonomic accessibility for operators.
