Xiongxing Brand Dual-Drive Bead Grinding Machine (Model N001).
Product Overview
The Xiongxing Brand Dual-Drive Bead Grinding Machine (Model: N001, Product No.: 810704001) is a high-efficiency device specifically designed for gemstone and jade processing. It is primarily used to grind pre-chamfered stone blanks into standard round beads in a single operation. The machine features a dual-drive design and a precision(tray) lifting handwheel mechanism, allowing precise adjustment of the tray height to control the working distance between the grinding disc and the bead grinding plate. This accommodates the grinding needs of beads with different diameters. It can process hundreds of blanks at once, greatly improving bead production efficiency and product consistency. The equipment is widely applicable for grinding round beads from various natural gemstones and jades, suitable for bead diameters ranging from 5mm to 20mm.
Product Brief
The Xiongxing Dual-Drive Bead Grinding Machine integrates the advantages of traditional bead grinders and fine grinding machines, combining rough grinding and fine grinding processes into a single device. Through the interaction between the grinding disc and the top cover, stone blanks are tumbled and ground between the grinding disc and the bead plate, enabling batch processing of multiple round beads in one go. This machine is suitable for grinding a wide range of materials including jade, agate, crystal, chalcedony, petrified wood, amber, amber & honey (amber and copal), ivory, cow bone, and hard woods. The processing range covers beads from 5mm to 20mm, with particular suitability for forming beads from 8mm to 20mm.
Core Features
1. Dual-Drive Design: The grinding disc and top cover are driven by independent motors. Grinding disc speed: 600 r/min; top cover speed: 100 r/min. The dual drive provides constant pressure from the top cover onto the stone blanks, making it suitable for processing soft materials.
2. High-Efficiency Batch Processing: Handles hundreds of blanks per batch, enabling large-scale, standardized bead production, significantly improving efficiency and product consistency.
3. Precision Tray Adjustment Mechanism: Equipped with a tray lifting handwheel for precise height adjustment of the tray (which holds the bead grinding plate). This controls the working distance between the grinding disc and the bead plate, accommodating bead diameters from 5mm to 20mm.
4. Stable Operation, High Precision: The grinding disc shaft uses a flat bearing for support, eliminating radial run-off during operation, ensuring bead roundness and surface finish meet fine grinding standards.
5. Wide Compatibility: Suitable for various natural gemstone and jade materials, as well as materials of varying hardness such as jadeite, agate, crystal, chalcedony, amber, and honey (amber/copal).
6. Easy Operation, Labor Cost Savings: One operator can run multiple machines simultaneously, significantly reducing processing costs for batch production.
Working Principle
The Xiongxing Dual-Drive Bead Grinding Machine uses a dual independent motor drive system. Pre-chamfered stone blanks are placed on a bead grinding plate loaded with abrasive. The tray lifting handwheel adjusts the tray height to create a working gap between the grinding disc and bead plate suitable for tumbling the blanks. In the dual-drive system, the grinding disc is driven by the main motor at high speed (600 r/min), while the top cover is driven by the secondary motor at low speed (100 r/min) in the opposite direction. During rotation, the top cover applies constant downward pressure on the blanks, causing them to tumble at multiple angles between the grinding disc and bead plate. Under the continuous action of the abrasive, the blanks are uniformly ground on all sides. This independent dual-drive control ensures constant pressure on the blanks, a stable, controllable grinding process, and the ability to grind hundreds of blanks into standard round beads in a single batch.
Functions & Operating Tools
I. Main Functions
1. Combined Rough & Fine Grinding: Completes the entire process from chamfered blank to finely ground round bead on a single machine.
2. Precision Size Control: The tray lifting handwheel allows precise adjustment of the processing size, covering the full 5–20mm range.
3. Batch Processing: Processes hundreds of blanks per batch, significantly improving production efficiency and product consistency.
II. Main Operating Tools
1. Tray Lifting Handwheel: Rotating this handwheel adjusts the tray height, thereby adjusting the gap between the bead grinding disc and the bead plate to suit different bead sizes.
2. Bead Grinding Plate & Abrasive: Holds the stone blanks and requires the use of abrasive steel grits of different mesh sizes.
3. Top Cover Pressure Adjustment Device: Used to adjust the pressure between the top cover and the workpiece, suitable for processing materials of different hardness levels.
Operation & Tool Methods
I. Preparation
1. Check that all machine components are securely installed and the power cord is properly connected.
2. Select the appropriate grinding disc (optional 250mm or 300mm) based on the hardness and size of the material to be processed.
3. Install the bead grinding plate on the tray and spread an appropriate amount of abrasive steel grit.
4. Evenly arrange the pre-chamfered stone blanks on the bead grinding plate.
II. Operating Steps
1. Adjust Tray Height: Turn the tray lifting handwheel to adjust the tray height according to the diameter of the beads to be processed, ensuring the gap between the grinding disc and bead plate matches the blank size.
2. Place Blanks: Place the bead grinding plate loaded with blanks onto the grinding disc.
3. Close Top Cover: Close the top cover securely and set the appropriate pressure using the pressure adjustment device according to material hardness.
4. Start the Machine: Connect the dual-drive power, then start the grinding disc motor and the top cover motor in sequence.
5. Grinding Process: During stable operation, the blanks tumble and grind between the grinding disc and bead plate. After the required processing time, stop the machine and remove the beads.
6. Inspect Beads: Remove the processed beads and check for roundness and surface quality. If necessary, replace with a finer abrasive for fine grinding.
III. Maintenance
1. Clean the bead grinding plate and grinding disc after each use to remove residual abrasive and powder.
2. Regularly check the operation of both drive motors to ensure no abnormal noise or overheating.
3. Periodically check all fastening screws to prevent loosening that could affect machine accuracy.
4. Regularly lubricate the tray lifting mechanism to keep the handwheel adjustment smooth.
Installation Steps
1. Select Installation Location: Choose a solid, level floor and a stable workbench. Ensure the machine is placed horizontally.
2. Position the Machine: Place the complete machine securely in the intended position, use the handwheels to level the base, and lock the machine firmly with mounting screws.
3. Connect Power: Verify that the local power supply voltage (AC 220V or 380V) matches the machine’s rated voltage, then connect the power cord correctly.
4. Install Grinding Disc: Install the selected grinding disc onto the main spindle, ensuring it is securely fastened before use.
5. Install Tray: Install the tray onto the lifting mechanism. Turn the tray lifting handwheel to test the lifting function for smooth operation.
6. Install Top Cover: Install the top cover onto its support bracket, checking that the cover opens/closes properly and the pressure adjustment device functions correctly.
7. No-Load Test: Turn on the power, jog the motors to confirm their rotation direction matches the arrows on the machine. Run at no-load for 5 minutes to check for abnormal vibration or noise.
8. Load Test: Perform a test run with a small number of blanks to confirm bead processing results and dimensional accuracy before proceeding to full batch production.
Core Advantages
1. Increased Efficiency: The dual-drive design integrates rough and fine grinding, processing hundreds of beads per batch for short production cycles.
2. Consistent Quality: Independent motor control ensures constant pressure, high roundness and precision, and excellent product uniformity.
3. Cost Control: One operator can run multiple machines simultaneously, significantly reducing labor costs.
4. Strong Compatibility: Suitable for all natural gemstone and jade materials, with a processing range covering 5–20mm beads.
5. Stable Operation: Flat bearing support eliminates radial run-off even under high loads, ensuring processing accuracy.
6. Export Advantage: Supports dual voltage options (220V/380V), complying with electrical standards of different countries and regions, with exports to Southeast Asia, the Middle East, Africa, South America, and beyond.
