Benefits

Benefits of Tristar Roller Burnishing Process

• Process improvement and low production cost.

• Accurate size, close tolerance in taper and ovality. 

• Mirror finish surface in one single pass. 

• Hardening of the finished surface increases by 5% to 10% 

• Attachable to lathes / boring / drill CNC / NC machines etc. 

• No skilled operator required. 

• Very easy interchangeable parts. ( e.g. rollers, mandrel, cage) 

• Avoids honing, lapping & other costly finishing operations

ADVANTAGES OF TRISTAR ROLLER BURNISHING TOOLS

A C C U R A T E    S I Z E 
Tristar roller burnishing tools consists of a built - in calibrated micrometer adjustable in size controlling extremely small increment to cover the tolerance range of any part. Parts produced by roller burnishing, with control in size to micron, levels with high constituency and repeatability.

M I R R O R    F I N I S H 
A very smooth surface finish as high as 0.2 Ra can be achieved by Tristar roller burnishing tools in seconds. It eliminates extra parts handling, additional machines and can also replace grinding, honing, lapping and other expensive secondary operations.

S U R F A C E    H A R D E N
The Tristar roller burnishing tools increases the surface hardness of the piece-part by 5% to 10% or more, thereby improving the fatigue life 
as much as 300% or better.

S A V E S    T I M E     A N D    L A B O U R
Using the built - in micrometer adjustment, set-up of Tristar roller burnishing tool takes less then a minute. Also an unskilled labour can operate unlike in other operations where labour skill plays a more important role in finishing. Thus less labour cost and high productivity saves much of production cost. 

I N T E R C H A N G E A B L E     W E A R     P A R T S
Wear parts such as rollers, guide rollers (cage), bearings, mandrels etc., can be easily replaced in Tristar burnishing tools because most parts in a series are standard. Thus convertibility features can save up to 50% of the cost of new tool for each new size needed.
