LBTP-1BC Touchscreen Fully Automatic Vacuum Grinding and Polishing Machine (Vacuum Adsorption with Stepless Speed Control)

The LBTP-1BC touchscreen‑controlled, fully automatic vacuum grinding and polishing machine is a single‑disc, fully automated system that integrates pre‑grinding, grinding, and polishing. Equipped with a vacuum assembly and vacuum suction cups, it is specially designed for grinding and polishing wafers, lenses, glass, and other thin‑section samples that are difficult to mount. Utilizing microcontroller technology, the machine is operated via a touch screen; the grinding/polishing disc is driven by a brushless DC motor with V‑belt transmission, while the grinding head is powered by a stepper motor with synchronous belt drive, offering smooth rotation, low noise, and long service life. Users can independently adjust the rotational speeds of both the grinding head and the polishing disc, set the applied pressure, and program custom sample‑preparation times to meet diverse requirements. A built‑in illumination system facilitates convenient sample handling, and an integrated cooling unit allows for temperature control during grinding, preventing overheating that could damage the metallographic structure. This makes the LBTP‑1BC an ideal choice for metallographic sample preparation in industrial facilities, research institutions, and university laboratories.

LBTP-1BC Touchscreen Fully Automatic Vacuum Grinding and Polishing Machine (Vacuum Adsorption with Stepless Speed Control)

Description

Product Introduction:

The LBTP-1BC touch-screen fully automatic vacuum grinding and polishing machine is a single‑disc, fully automated system that integrates pre‑grinding, grinding, and polishing. Equipped with a vacuum assembly and vacuum suction cups, it is specially designed for grinding and polishing thin‑walled components such as wafers, lenses, and glass—materials that are difficult to mount. The machine employs microcontroller technology and is controlled via a touch screen. The grinding/polishing disc is driven by a brushless DC motor with V‑belt transmission, while the grinding head is powered by a stepper motor with synchronous belt drive, offering smooth rotation, low noise, and long service life. Users can independently adjust the rotational speeds of both the grinding head and the polishing disc, set the applied pressure, and program custom sample‑preparation times to meet diverse requirements. A built-in illumination system facilitates convenient sample handling, and an integrated cooling unit allows for temperature control during grinding, preventing overheating that could damage the metallographic structure. This makes the LBTP‑1BC an ideal choice for metallographic sample preparation in industrial facilities, research institutions, and university laboratories.
