Unlike conventional CNC grinders, which efficiently process standard geometries in batches, optical surface grinders project the workpiece and grinding wheel profiles onto a screen, allowing real-time monitoring of the grinding process. Deviations can be detected and compensated manually or via CNC, making them ideal for machining non-standard parts.

OTURN offers a variety of optical surface grinders: standard, multi-axis, and large-surface processing with a mechanical grinding head. Whether you manufacture molds, provide small-batch customization services, or run other business models, our high-precision optical surface grinders are ideal for expanding your business.

Our machines feature a highly rigid machine base and spindle, along with high-quality ceramic bearings, ensuring stable operation. Quick tool changers effectively reduce vibration and extend tool life. Servo motors precisely control the machining process and can be turned off at scheduled times to save energy.

If you require a highly flexible optical grinder with higher precision, a user-friendly interface, and human-machine interaction, please contact OTURN for the latest quote.

Precision Instrument and Mold Manufacturing

Commonly used for machining parts requiring extremely precise curves, such as precision forming dies, templates, punches, and rollers; its projection system monitors the workpiece contour at any time to raise forming accuracy.

Aerospace

Used for machining aerospace components with extremely complex contours, such as turbine blade contours and free-form curves in complex structural parts.

Automotive

Used for manufacturing components in engines and transmission systems that need to be highly precise. The future development of electric driving will further drive the demand for high-precision parts, making optical grinders a key solution.

Medical Device and Tool

When manufacturing medical devices (like minimally invasive tools and implantable equipment) and precision mechanical tools (like end mills and drill bushings), optical grinders can achieve submicron contour control and excellent surface quality.

Electronics and Optical Components

The manufacturing of tiny precision parts (like connectors and micro parts) in the electronics industry requires very strict precision, and optical grinders meet this demand with their fine forming capabilities. Furthermore, in the optics industry, optical grinders are essential for rough machining and contour generation of optical shapes, such as lenses and lenses.

Tool and Mold Manufacturing

Used for grinding complex curved cavities in injection and stamping molds, ensuring part quality and surface finish.

New materials and precision parts in the aerospace and automotive industries

Optical grinding machines are becoming more important because of their precision, like the machining of micro, electric, and complex-shaped parts.

Optical curve grinders are expensive machines, so their production volume in China is low. As a leader in China’s precision CNC machine industry, OTURN can control costs and provide you with cost-effective optical curve grinders. We not only attach importance to quality but also complete finishing solutions. In addition to manufacturing machines, we also provide a comprehensive CAM program that explains to make your workers quickly master the program, reducing the cost of training new personnel. Our 24/7 online customer service team provides real-time answers to technical questions, providing all-around after-sales service.

This type of equipment is typically expensive, especially imported models. The complex approval and import procedure can be very high. Industry reports indicate that high investment and operating costs seriously hinder small and medium-sized manufacturers from using it.

Although optical contour grinders appear intuitive, their operation relies on human imaging observation and curve compensation. Their complexity necessitates systematically trained technicians to bring into play, and the absence of skilled operators often limits widespread adoption.

Traditional in-line inspection of optical contour grinders relies on a human’s judgment using geometric optical images. This way often only allows for qualitative judgment and lacks quantitative compensation capabilities. Furthermore, due to the limitations of the grinding wheel’s motion, this can lead to precision problems, as you can’t achieve a perfect finish in one pass.

Optical curve grinders require extremely continuous and precise grinding paths, which demand that the toolpaths generated by the CAM system be extremely accurate; even the slightest mistake can influence the final contour shape.

Furthermore, most traditional CNC systems support only linear or circular interpolation, while optical grinding typically involves free-form interpolation. Currently, only a few high-end control systems support this advanced interpolation.

Standard CAM software, although useful for engraving and milling, generally lacks support for optical curve grinding. In practice, this need using the grinder manufacturer’s proprietary CAM/post-processing program or adjusting the G-code in hand to suit the machine’s kinematic characteristics.

Even when using CAM software to create the path, the craftsman still needs to fine-tune detas, watch out disturbs, and evaluate cutting allowances. Optical grinders often require real-time monitoring of the tool’s alignment with the workpiece contour and compensation based on visual projection feedback. Without sufficient experience, relying solely on CAD/CAM software usually can’t achieve precise shaping. Due to the precision of the machined object and the complexity of the locus, when an error is discovered after path generation, rework or reprogramming is often required. The investment in CAM debugging is significantly higher than that of machining programs for standard geometries.

Grinding wheels: These include diamond or CBN grinding wheels, used for precision contour grinding. These wheels wear out over time and require regular replacement or revising to maintain machining accuracy and surface quality.

Grinding wheel adapters/flanges: These are hardened attachments used to mount grinding wheels. These components may become deformed or misaligned over time.

Dressing tools: These include single-point diamond and electroplated diamond tools, used to restore grinding wheel profile and sharpness. These tools themselves also wear out and need to be replaced to raise dressing efficiency.

Image system components, including lenses, projection mirrors, and lighting devices, are used for shape projection. They should be cleaned or replaced to keep clear and completely aligned images.

Machine tool moving parts: These include lead screws, guideways, bearings, etc. These components may be inaccurate or become stuck after long-term use.
