Grinding Drives TRIZ Cases
- Polishing Head and Transfer Station Alignment Using Two-Sensor Calibration
Two-sensor distance monitoring aligns polishing head and transfer station axes faster, with lower complexity and minimal detection error.
- Electro Spindle Turret Head for Low-Vibration Surface Grinding
Independent electric spindles replace shock-prone gear trains, enabling compact grinding heads for curved surfaces with lower vibration.
- Compressed-Gas Bubble Cooling for Fixed-Temperature Liquid Supply
Compressed gas bubbles cool tank liquid to a set temperature, cutting semiconductor process cooling energy, size, and operating cost.
- Fine Adjustment Thread Assembly for Tilted Grinding Load Sensing
Different-pitch threads and a compressed joint sensor keep grinding load measurement accurate during tilt adjustment and spacing changes.
- Laser-Altered Holding Jig for Uniform Wafer Grinding
A laser-formed altered layer creates a suction path in the holding jig, preserving wafer flatness while maintaining suction during grinding.
- Grinding Spindle Magnetic Bearing Control for Ring-Specific Precision
Stored magnetic-bearing coefficients are selected by grinding wheel and bearing ring type to keep rotor guidance precise during dressing and grinding.
- Cylindrical Workpiece Grooving With Vertex Detection Alignment
Optical vertex detection guides blade orientation during cylindrical grooving, avoiding axis matching while maintaining high cutting accuracy.
- Cam-Adjusted Stroke Assembly for Balanced Random Orbital Motion
A cam, counterweight, and locking ring vary orbital stroke without tools, balancing cutting action, control, motor strain, and pad life.
- Hydraulic Rotary Tool Chuck for Long-Reach Low-Vibration Machining
Liquid-driven rotation inside the tool suppresses vibration in long-reach machining while maintaining accuracy, torque, and lubrication.
- Axicon Cone Surface Finishing With Oscillating Abrasive Contact
Oscillating linear abrasive contact during axicon rotation prevents radial grooves, improves cone-surface finish, and corrects angle errors.
- Concrete Surface Machine With Self-Propelled Tool Carriers
Independent electric tool carriers generate variable force for concrete processing and self-locomotion, reducing transmission complexity and operator dependence.
- Random Orbital Stroke Adjustment Mechanism for Variable Orbit Control
A gear-driven stroke adjuster varies orbital radius during use, balancing control stability with wider surface coverage and lower pad wear.
- Dual-Shaft Machine Tool With Freewheel Clutches for Fewer Tool Changes
A reversible drive and dual freewheel clutches let one machine tool switch between two rotatable tools, improving force control and reducing tool changes.
- Kinematically Separated Grinding Spindles for Faster Tool Changes
Independent tool and workpiece spindles enable overlapping tool and workpiece changes, boosting grinding throughput without sacrificing precision.
- Pivoting Grinding Head and Suction Hose Layout for Wall Guidance
A pivoting grinding head, protected suction hose, and spring-loaded base position improve wall guidance while reducing hose damage.
- Spindle Tip Groove Structure to Block Swarf-Laden Liquid
Alternating gap sections around the spindle tip create pressure loss and centrifugal discharge, limiting swarf buildup and cleaning needs.
- Fiber-Resin Oscillating Linkage for Faster Bearing Superfinishing
Fiber-reinforced resin linkage parts cut oscillating mass, enabling faster bearing superfinishing with less vibration, noise, and process time.
