200 mm vs 250 mm 4th Axis Rotary Table

Introduction

Two of the most common sizes for 4th axis rotary tables are 200mm and 250mm. While they look similar, they serve different machining needs based on workpiece size, weight, and machine space.

1. 200 mm Rotary Table (e.g., HY200)

Best For: Small to medium-sized parts, tight machine enclosures, and applications requiring high indexing speeds.

Advantages: Lighter weight, easier to install and remove manually, requires less machine table space.

Limitations: Lower load capacity and smaller through-hole.

2. 250 mm Rotary Table (e.g., HY250)

Best For: Larger, heavier workpieces, multi-side machining of boxy parts, and applications requiring a larger T-slot area.

Advantages: Higher rigidity, larger through-hole for long shafts, higher load capacity.

Limitations: Heavier, takes up more machine table space, might interfere with the machine enclosure on smaller VMCs.

Conclusion

If your parts are generally under 50 kg and space is limited, the 200mm is a versatile choice. If you frequently machine heavier parts or need a larger clamping area, the 250mm offers better stability. Contact us with your workpiece dimensions for a precise recommendation.
