High-Performance Touchscreen Metallographic Grinding Machine with User-Friendly Interface for Beginners

Unlock Precision with the High-Performance Touchscreen Metallographic Grinder

As a beginner in metallographic sample preparation, mastering the grinding process can seem challenging. Fortunately, the LaiZhou Jincheng Industrial Equipment Co., Ltd. has engineered a high-performance touchscreen metallographic grinder tailored to simplify your workflows with a user-friendly human-machine interface and an advanced four-speed constant-speed system. This guide will walk you through the touchscreen interface, stepwise speed control, and standard sample grinding workflows — empowering you to avoid common pitfalls and enhance your results with confidence and efficiency.

Intuitive Touchscreen Menu: Control at Your Fingertips

The grinder's touchscreen control panel is designed for clear, logical navigation enabling seamless mode switching, speed adjustments, and timer settings. You can toggle between pre-set grinding modes or customize parameters to fit your material’s unique demands. The menu system employs easily recognizable icons and prompts, minimizing the learning curve for newcomers.

Key touchscreen features include:

• Four grinding speed levels (500, 700, 900, 1100 RPM) for precise control.
• Timer settings up to 60 minutes with audible alerts.
• Real-time display of speed and elapsed time.
• One-touch start/stop and pause for flexible operation.

Such clarity in design dramatically cuts down your trial time, enabling you to focus on grinding consistency and sample quality.

The Power of Four-Speed Constant-Speed System

Your metallographic samples require carefully graduated grinding stages to achieve the ideal surface finish. The grinder’s four-speed constant-speed system supports precisely that — from coarse pre-grinding to fine polishing.

Here’s how the four speeds typically apply in the grinding workflow:

Consistent rotational speed during each stage ensures uniform abrasion and superior metallographic sample quality.

Step-By-Step Sample Grinding Workflow

Follow this standardized grinding process to maximize your success rate:

1. Sample mounting: Secure the specimen firmly using appropriate mounting media.
2. Pre-grinding: Set the grinder to 500 RPM, apply coarse abrasive paper, and grind for 2-3 minutes.
3. Intermediate grinding: Switch to 700 RPM with medium grit paper, grinding for 2 minutes to diminish deeper scratches.
4. Fine grinding: Increase speed to 900 RPM with fine abrasive, grinding 1-2 minutes to smooth surface.
5. Polishing: Finish at 1100 RPM with polishing cloth and diamond suspension for 3-5 minutes until surface is mirror-like.

Always rinse and dry the sample between each stage to prevent contamination and scratching.

Handy Tips & Troubleshooting for New Users

• Tip: Regularly check the abrasive paper condition—replace ASAP once clogged to maintain efficiency.
• Tip: Use gentle, uniform pressure to avoid uneven grinding or sample deformation.
• Troubleshooting: If speed fluctuates, verify motor calibration or contact support.
• Troubleshooting: Excessive noise may indicate worn bearings—our low-noise design minimizes this, but prompt servicing is advised.

The machine’s durability is designed for long-term use in demanding lab environments, coupled with an industry-leading warranty and responsive after-sales service to support your metallographic journey.
