The capacity output of a cylindrical grinding machine depends on several factors, including the machine’s size, power, grinding wheel specifications, workpiece material, and required precision. Below are key parameters that define its capacity:
1. Workpiece Dimensions (Typical Capacity Range)
– Maximum Grinding Diameter: 100 mm to 500 mm (some industrial machines go up to 1000+ mm)
– Maximum Grinding Length: 300 mm to 3000 mm (varies based on machine model)
– Swing Over Bed: 150 mm to 600 mm
– Distance Between Centers: 500 mm to 6000 mm (for center-type cylindrical grinders)
2. Power & Speed
– Motor Power: 5 kW to 50 kW (higher for heavy-duty grinding)
– Wheel Speed: 1200–2000 RPM (depends on wheel diameter and material)
– Workpiece Speed (Rotational): 50–500 RPM (adjustable for precision grinding)
3. Material Removal Rate (MRR)
– Depends on workpiece hardness and wheel grit:
– Soft Materials (Aluminum, Brass): Up to 50–100 cm³/min
– Hardened Steel/Alloys: Around 10–30 cm³/min

4. Tolerance & Surface Finish
– Dimensional Tolerance: ±0.002 mm to ±0.01 mm
– Surface Finish (Ra): 0.2–1.6 µm (can be finer with superfinishing)
5. Production Rate
– Depends on cycle time:
– Rough grinding: ~1–5 min per part
– Precision finishing: ~5–20 min per part
– Automated CNC grinders can achieve higher throughput (~10–50 parts/hour).

6. Common Applications & Industries
– Automotive (crankshafts, camshafts)
– Aerospace (turbine shafts)
– Tool & Die manufacturing
– General precision engineering
