HPA-2000S (Multi-point pressure & center pressure) Fully automatic metallographic grinding and polishing machine
Product Introduction
HPA-2000S fully automatic metallographic grinding and polishing machine simultaneously supports:
- Multiple samples loaded independently
- Sample tray center loading
Holds six samples at a time and can be equipped with a four-channel automatic dispensing device (optional) to complete the grinding and polishing process in a fully automated manner.
Features
- HPA-2000S fully automatic single and double disc metallographic grinding and polishing machines, simultaneously supporting multiple samples loaded independently and sample tray central loading, fixing six samples (up to eight can be customized) at once to complete the entire grinding and polishing process
- Grinding and polishing discs and sample discs: Set and run all grinding and polishing parameters such as rotation speed, grinding and polishing time, rotation direction, and water valve closure, with automatic saving for easy recall
- PLC + 1KW high-power motor system
- Uses two independent 1KW high-power motors with high torque that remains constant regardless of speed
- Wide speed range, from 5 rpm to 1000 rpm (maximum 1500 rpm)
- Turntable can start and stop quickly; stops rotating in just 2 seconds
- All grinding and polishing parameters automatically saved and easily recalled
- Imported PLC brand for reliable quality
- Touchscreen interface for convenient parameter setting
- 3 working modes:
- Fully automatic mode: 99 sets of processes (flows) can be set and recalled, each containing 10 steps of process parameters
- Multi-process mode: 30 process parameters can be set and called for each grinding and polishing step
- Manual mode: Operate specific functions of the device individually
- Stores 100 processes with import/export capability
- Sample grinding layer thickness control: Precisely control the amount of sample removed during grinding (optional)
- Includes 1, 4, or 6-channel automatic dripper (optional) with three operating modes: manual, online, and fully automatic
- Grinding head features electromagnetic automatic locking for greater convenience
- Easily replace magnetic anti-stick disc; one disc equivalent to N discs
- Switch between Chinese and English interfaces
- Mobile remote control operation (optional)
