WHAT MAKES ROYAL LIVE CENTERS

THE MOST RIGID?

Royal Point

Other Brand Point

The cross-sectional area of the point on the Royal Center is 68% larger

than that of the other brand, making the Royal point much more rigid and

less likely to deflect under load.

Royal's thick, beefy point offers superior rigidity, resulting in tighter part

tolerances and chatter-free surface-finishes.

Point Analysis of 4MT Spindle Type Live Centers

D1 = Diameter of Royal Point = .603"

D2 = Diameter of Other Brand Point = .465"

Cross-Sectional Area of Royal Point = .285 sq. in.

Cross-Sectional Area of Other Brand Point = .170 sq. in.

One of the most common misconceptions regarding live centers

relates to the internal length of the rotating point.

Some manufacturers believe that a long, thin point provides more

rigidity than a short, thick point. But in fact, the opposite is true.

In order to verify that Royal’s short, thick point provides superior rigidity

over a long, thin point, we built the test fixture pictured above.

Here’s how it works:

• Both live centers have holes drilled in their shanks corresponding

to the indicator locations.

• As radial force is applied evenly to the point tips by turning a

centrally-located screw, the indicators are able to measure the

internal deflection of each point.

• Almost immediately upon application of the load, the indicators

show that the competitor’s point flexes 600% more than the

Royal point!
