Description
Product Introduction:
The LBTP-1B touchscreen‑controlled automatic metallographic sample grinding and polishing machine is a single‑disc, fully automated unit that integrates preliminary grinding, fine grinding, and polishing. It employs microcontroller technology with touch‑screen operation; the grinding/polishing disc is driven by a brushless DC motor via a V‑belt, while the grinding head is powered by a stepper motor with synchronous belt drive, ensuring smooth rotation, low noise, and long service life. Users can independently adjust the rotational speeds of both the grinding head and the disc, set the applied pressure, and program custom sample‑preparation times to meet diverse requirements. The instrument features an integrated illumination system for convenient sample handling and a built-in cooling unit that cools samples during grinding, preventing overheating and preserving the metallographic structure. It is an ideal choice for metallographic sample preparation in industrial facilities, research institutions, and university laboratories.
Product Features:
1. The base is integrally cast from aluminum alloy, offering lightweight construction, excellent shock absorption, and superior corrosion resistance.
2. The housing is integrally molded via ABS thermoforming, featuring a modern appearance and excellent corrosion resistance.
3. The faucet features an all-copper, chrome-plated finish, offering excellent corrosion resistance.
4. Equipped with a touch-screen control and display, it offers simple operation and clear, intuitive visualization.
5. One-touch automatic start function: After placing the sample on the holder, simply press Start; the indenter will automatically descend, the grinding head and grinding disc will run automatically, and the water tap will dispense water. Once grinding and polishing are complete, the water tap will shut off automatically.
6. Features programmable timing, speed, and pressure settings.
7. Built-in nozzle with an integrated dirt collection tray for automatic cleaning.
8. Supports stepless speed control or four-speed adjustment modes, making speed regulation more convenient.
9. The grinding head features electromagnetic clutch‑based automatic locking for convenient and rapid operation (optional).
10. Supports both independent and synchronized start-up of the grinding/polishing disc and the grinding/polishing head, offering greater flexibility in operation.
11. It can store over 100 sets of grinding and polishing process parameters, enabling quick retrieval.
12. Magnetic disc design supports quick disc changes, making it easier and faster to swap sandpaper and polishing cloths.
13. The specimen holder automatically releases and clamps, and, in conjunction with the internal illumination system, facilitates easy specimen loading and unloading.
14. Equipped with a quick‑change specimen‑clamping disc, allowing for the easy replacement of clamping discs of different diameters at any time.
15. The entire machine is equipped with brushless DC and stepper motors, ensuring smooth operation, low noise, and long service life.
16. The emergency stop button allows for quick and convenient immediate cessation of operation.
