Variable-Frequency Steel Ball Grinding System
The main spindle and turntable use frequency-conversion speed regulation, allowing continuous adjustment for different ball sizes, materials and grinding stages. The 40–130 r/min spindle speed range helps operators balance grinding efficiency, heat generation and surface quality.
Hydraulic Loading and Mechanical Pressure-Holding System
The machine uses hydraulic loading together with mechanical pressure holding. A compression spring and constant-pressure locking nut help maintain stable grinding force during the machining cycle, reducing pressure fluctuation and supporting more consistent batch results.
Heavy-Duty Spindle and Sealed Bearing Structure
A high-capacity end-face bearing supports continuous heavy-load operation. The mechanical seal used on the main-spindle bearing reduces the risk of oil leakage, helping improve reliability, cleanliness and maintenance performance.
Reliable Steel Ball Grinding Machine Transmission
The reduction gearbox transfers power to the spindle through a gear pair and bevel-gear output shaft. This straightforward transmission structure supports smooth operation, dependable power delivery and easier routine maintenance.
Large-Cycle and Small-Cycle Steel Ball Processing
The vertical large-cycle design supports efficient batch grinding. For special processing requirements, the 3M7480 can also operate in a small-cycle configuration without the turntable, giving steel ball manufacturers greater production flexibility.
