Jewellery rolling machine with heavy load wheel, Manual

Product Details

A jewellery rolling machine described as having a "heavy load wheel" is typically a robust, high-capacity electric or semi-automatic rolling mill designed for heavy-duty, continuous use in professional workshops. The "heavy load wheel" is often a large, heavy flywheel that provides momentum and significant force, which is particularly beneficial for rolling harder metals like low-purity silver and for achieving greater material reduction with less power input. Product Description and FeaturesThis type of rolling machine is a floor-model unit with a sturdy, often cast iron or heavy steel, fabricated body designed to withstand significant stress and vibration.  Rollers: The core components are the high-chromium special steel rollers, which are hardened and ground-finished to ensure a smooth, mirror finish on the processed metal and offer superior wear resistance. Roll sizes vary, with common examples being 5" x 2.5" (127mm x 63.5mm) or 6" x 3" (152mm x 76mm). Capacity & Functionality: They are designed for cold rolling and are often "combined" mills, featuring sections for creating flat sheets, square wires (with multiple grooves of varying sizes), and half-round grooves for items like ring shanks or bangles. Heavy Load Wheel (Flywheel): The prominent "heavy load wheel" acts as a large flywheel, storing rotational energy. This momentum allows the machine to efficiently handle large or hard metal stock, such as gold, silver, copper, and brass, reducing the strain on the motor and ensuring smooth, consistent pressure. Drive System: These are primarily electric or semi-automatic machines, powered by motors (e.g., 1.5 HP to 7.5 HP) to facilitate easier, high-volume production compared to purely manual mills. They typically incorporate heavy-duty gearboxes with a high reduction ratio (e.g., 4:1 gear ratio is common in similar models) to multiply torque and minimize the force required for operation. Additional Features: Automatic lubrication systems are often a standard feature on the gear mechanisms to ensure smooth and noiseless operation and extend machine life. Control Panel: Equipped with an electric motor and a control panel featuring on/off push buttons and reverse/forward switches. Weight: These are heavy units, with net weights often exceeding 260 kg (approx. 573 lbs), requiring a stable, strong floor installation.  This machinery is ideal for professional jewelers and small-scale manufacturing units that require durability, high-precision rolling, and the power to process a significant amount of material efficiently.
