Fully automated machine processing center for jade, emerald, and agate bead pressing

The fully automatic jade bead press (also known as an automatic cylinder press) is the core automated equipment used in jade, jadeite, and agate processing to transform raw sheets into cylindrical bead blanks.

I. Function (What to Do)

• Automatically stamp/cut cylindrical bead blanks from thinly sliced jade materials (such as jadeite slices or agate slices).

• The first step in producing ball bearings, bucket bearings, and legacy-type bearings (greening process)

• replaces traditional manual bead suction/baking methods, offering higher efficiency, reduced labor costs, and consistent finished product quality

II. Working Principle (In Simple Terms)

1. Place the jade piece on the workbench

2. Automatic positioning: The machine automatically aligns with the pressing cylinder (mold).

3. Stamping: The servo motor drives the pressing cylinder to rotate at high speed and perform downward punching, forming a cylindrical shape.

4. Material discharge: Pearl embryos fall automatically and undergo cyclic processing.

III. Main Structure

• Servo/closed-loop motor: High power output, low vibration, and excellent precision

• Multi-station (dual-head/triple-head): Presses multiple items simultaneously for higher efficiency

• Pressing cylinder (mold): Determines the bead diameter (commonly 6–20 mm)

• Intelligent control system: automatic tool setting, load sensing, crack prevention

• Cooling/Dust Removal: Water cooling protects the jade and cutting tools

IV. Core Functions

• One-touch automatic compression cylinder: No manual positioning required

• Multi-speed adjustment

◦ Grades 1–5: Standard material (high efficiency)

◦ Grades 6–10: Ice material, cracked material, cat-eye material (anti-cracking)

• Intelligent protection: Automatic shutdown alarm for overload, needle breakage, and wear

• Independent workstation: If one fails, the others can continue operating

V. Efficiency and Applicability

• Production capacity: Approximately 150–250 units per hour for a single head; doubles for dual/triple heads

• Applicable to: hard minerals such as jadeite, Hetian jade, agate, crystal, and emerald.

• Pearl embryo size: Commonly available in 6mm, 8mm, 10mm, 12mm, 14mm, 16mm, 18mm, and 20mm

VI. Processing Process (Whole Line)

1. Raw stone → Slice machine → Jade slices

2. Jade stone pieces → Fully automatic bead pressing machine → Cylindrical green bodies

3. Cylindrical坯 → Rounder → Spherical beads

4. Beads → Perforator → Polishing/Grinding → Final beads
