Robotic Polishing Machine for Flat/Spherical/Aspherical Optical Components Processing

Robotic polishing machine is an automated processing equipment that integrates industrial robots, force control devices, polishing tools, and professional software control systems. It represents a modern upgrade of traditional polishing processes, aimed at addressing issues such as low efficiency, inconsistent quality, high labor costs, and poor working environments associated with manual polishing.

Robotic Polishing Machine Main Working Principles

Its working principle can be summarized as "human-like" refined operation but surpassing human limitations.

1. Path Planning: First, the precise 3D data of the workpiece is obtained through 3D scanning or CAD models. Subsequently, the robot’s motion trajectory is planned in offline programming software to ensure the polishing tool covers all areas to be processed.

2. Constant Force Control: During polishing, the force control device continuously monitors the contact force between the tool end and the workpiece surface. If a deviation in force is detected (e.g., increased force on protrusions, decreased force on recesses), the system immediately issues commands for the robot to fine-tune its posture or position, maintaining the applied force at a preset optimal value. This is key to achieving uniform and consistent surface quality.

4. Parametric Execution: The robot strictly follows preset process parameters, including:

• Tool speed: Affects cutting efficiency and surface roughness.
• Polishing pressure: Directly influences material removal rate and surface gloss.
• Feed rate: The speed at which the robot moves, directly related to polishing efficiency.
• Overlap rate: Ensures no unpolished areas between paths.

5. Data Recording and Optimization: Parameters and data from the entire process can be recorded and traced, providing support for subsequent process optimization and quality analysis.

Robotic Polishing Machine Main Application Areas

 

Robotic polishing automation solutions are widely used in industries with high requirements for surface quality:

 

 

1. Aerospace:

• Application objects: Engine blades, casings, aircraft skins, rocket shells, landing gears.
• Demand analysis: These components are often made of hard-to-machine materials such as high-temperature alloys and titanium alloys, with complex profiles and extremely high requirements for surface integrity, fatigue strength, and aerodynamic performance. Robotic polishing can stably remove recast layers, control surface roughness, and avoid stress concentration caused by manual operations.

 

2. Automotive Industry:

• Application objects: Automotive hubs, engine covers, exhaust pipes, body molds, interior parts.
• Demand analysis: Mass production requires extremely high efficiency and quality consistency. Robotic polishing can meet the mirror-finish requirements for products like hubs and efficiently handle complex surfaces of large panel molds.

 

3. Medical Devices and Artificial Implants:

• Application objects: Orthopedic implants (hip joints, knee joints), surgical instruments, dental implants.
• Demand analysis: Extreme requirements for surface smoothness, sterility, and biocompatibility. Robotic polishing can achieve ultra-smooth surfaces (up to Ra < 0.1μm), reduce bacterial adhesion, and avoid sharp edges, improving the long-term safety of implants.

 

4. Consumer Electronics and 3C Industry:

• Application objects: Smartphone frames, laptop casings, smartwatch cases, glass covers.
• Demand analysis: Rapid product iteration, high requirements for appearance parts such as high gloss, scratch-free surfaces. Robotic polishing can efficiently process materials like aluminum alloy, glass, and ceramics, achieving high-end appearance effects such as "unibody metal" casings.

 

5. Kitchenware and Home Furnishing Industry:

• Application objects: Faucets, stainless steel sinks, high-end hardware, furniture handles.
• Demand analysis: Pursuit of mirror effects and durability. Robots can replace manual labor for repetitive and heavy polishing tasks, ensuring product aesthetics and consistency while reducing health hazards from dust to workers.

 

6. Energy Equipment:

• Application objects: Nuclear power blades, hydro turbine blades, gas turbine components.
• Demand analysis: Large-scale components with complex profiles, where surface quality directly affects energy conversion efficiency and service life. Robots can efficiently complete polishing tasks for such oversized components through offline programming.
