The "TCV-2D model" is a vertical core drilling machine that processes ultra-telephoto lenses and the outer circumference and beveling of flat glass from digital cameras. To maintain the outer diameter processing accuracy for workpieces with a maximum size of φ150×thickness up to 40mm, it incorporates high-precision guides in the slide section for the grinding wheel shaft. Additionally, after polishing, it aligns the center of the device's rotation axis with the optical axis that connects the curvature centers of both sides, allowing for grinding of the outer circumference to specified shape dimensions, as well as simultaneous beveling work to prevent chipping. 【Features】 ■ A vertical core drilling machine using a bell chuck/vacuum chuck method that can stably process lenses with a maximum diameter of φ150, which can become unstable with horizontal core drilling machines. ■ Eccentricity accuracy can be measured from the amount of movement of the image displayed on the monitor, allowing for pass/fail judgment against a user-defined tolerance. ■ The appropriate grinding wheel feed speed and workpiece axis rotation speed can be freely input from the touch panel. ■ Special specifications can be accommodated after detailed specification discussions. *For more details, please refer to the PDF document or feel free to contact us.

The "HP500/600/1000" is a one-axis polishing machine suitable for high-precision polishing of large lenses, polishing plates, and more. The rotation speed of the dish axis and the number of spindle strokes can be selected under optimal conditions using inverter control. Additionally, the front of the tank is open, and there is ample space on the sides and depth, making it easy to load and unload workpieces. 【Features】 ■ One-axis polishing machine ■ Ideal for high-precision polishing of large lenses and polishing plates ■ Rotation speed of the dish axis and number of spindle strokes are inverter-controlled ■ Easy loading and unloading of workpieces *For more details, please refer to the PDF document or feel free to contact us.

The "TCV-4 type" is a vertical automatic centering machine that processes the outer circumference and chamfering of lenses for digital cameras, in-vehicle cameras, surveillance cameras, and flat glass. The workpiece is transported by an XY robot, and processing is carried out in "fully automatic" operation. Additionally, by compactly integrating the stocker and loader sections, the overall device has been made more space-efficient. 【Features】 - Automatic vertical centering machine for single-lens reflex and interchangeable lenses with one axis - Adoption of rolling guides in the moving axis guide mechanism to reduce sliding resistance - Improved processing eccentricity during metal wear due to rolling guides, with functional enhancement effects against low Z values - Enhanced spindle rigidity with a DBT configuration of φ50 for both lens and bell axes, and φ60 for the grinding wheel axis - Achieved an outer machine diameter of within 1,000mm, with the stocker and loader designed for compact space *For more details, please refer to the PDF document or feel free to contact us.

The "TCH-3W-TL5 model" is a horizontal automatic centering machine that processes the outer circumference and chamfering of lenses for digital cameras, in-vehicle cameras, surveillance cameras, and flat glass. The workpiece is transported by an XY robot, and processing is carried out in "fully automatic" operation. By placing the stocker unit at the top of the device, we have achieved a compact design. Additionally, it is equipped with a manual function, allowing it to process workpiece sizes that cannot be handled by automatic loading. 【Features】 - By adopting a rolling guide mechanism for the moving axis, we have reduced sliding resistance. - The rolling guide improves processing eccentricity values during metal wear, providing functional enhancement against low Z values. - The lateral movement of the moving axis has shifted from a rack mechanism to a center push method, effectively preventing holder scratches on soft glass materials. - The automatic machine's stocker and loader device is designed in a two-story format, achieving space-saving. - Lenses larger than the automatic loading compatible size (maximum φ40) can be handled manually (maximum φ105). *For more details, please refer to the PDF document or feel free to contact us.

The TCH-2W-SC and TCH-2TSA-SC models are horizontal manual centering machines that perform processing on the outer circumference and chamfering of lenses for digital cameras, automotive applications, surveillance cameras, and more. After polishing, the center of curvature of both sides is aligned with the optical axis connecting them, allowing for the grinding of the outer circumference to specified shape dimensions. Chamfering can also be performed simultaneously to prevent chipping, among other purposes. Furthermore, with the addition of a transmissive reading device, it is possible to achieve high eccentricity precision while monitoring, even for lenses with low Z values where automatic centering is difficult. 【Features】 - High eccentricity precision can be achieved while monitoring with a transmissive reading device, even for lenses with low Z values (where automatic centering is difficult). - After centering, high-precision processing is possible by inputting processing conditions suited to the lens shape through servo control. - Special specifications can be accommodated after detailed specification discussions. *For more details, please refer to the PDF document or feel free to contact us.

The "BRS-01 model" is a horizontal manual processing machine that enables simultaneous polishing of the outer circumference and beveled edges of workpieces, primarily for cover glass for smartphones, through synchronized operation of the work axis and brush mounting axis. The number of layers that can be stacked at once depends on the thickness of the workpiece. Standard specifications allow for polishing of round, square, polygonal, oval, and elliptical shapes. 【Features】 ■ Simultaneous polishing of flat and beveled surfaces ■ Adoption of servo motors that accommodate square, rectangular, and polygonal shapes, ensuring even contact of the brush with the workpiece ■ Custom specifications can be accommodated after detailed specification discussions *For more details, please refer to the PDF document or feel free to contact us.

The "TCH-2KS-TL3 model" is a horizontal automatic centering machine suitable for processing hard materials, such as automotive lenses that involve high loads. It performs processing on the outer circumference and beveling of lenses and flat glass, addressing chipping issues that arise from the unique shapes of automotive lenses. Additionally, it allows for easy shape processing of not only circular shapes but also irregular shapes by simply selecting a shape from the touch panel and entering values. 【Features】 ■ Freely input the grinding wheel feed speed suitable for the shape and material of the lens ■ Standardization of inverter control for the grinding wheel axis and power-up for the work axis ■ Easy processing of circular, D-shaped, I-shaped, square, oval, and other shapes ■ High repeat positioning accuracy, capable of handling small diameter lenses ■ Automatic correction of grinding wheel movement *For more details, please download the PDF or feel free to contact us.
