Burnishing Media – Ovalballs Stainless Steel Tumbling Media
Why we need Ovalballs stainless steel burnishing media?
Ovalballs stainless steel burnishing media offer more oscillation movement between media and parts. Therefore, it offers more parts and media contact then ball shape stainless steel media.
General Advantage of Burnishing Media:
Stainless steel burnishing media can made into various size and shape. Most common shape is: stainless steel balls, stainless steel ballcone, stainless steel diagonal, ovalballs and so on. Recently we have developed Stainless steel Jewelry mix with combination of stainless steel tumbling media of different size and shape.
There are also various material available for steel tumbling media: AISI 304, AISI 201, AISI 420 and so on. Among them, stainless steel tumbling media is the most popular media use for ball burnishing.
Steel Tumbling Media (AISI 304) have the advantage of faster ball burnishing times. Besides, it eliminates the need for expensive, consumable rust inhibitor solutions. In addition, the maintenance procedures for overnight and longer-term shutdowns are simpler.
Comparatively, carbon tumbling media (AISI 201) have higher storage cost from rust inhibitor. Besides, it have also other maintenance and handling cost.
AISI 420 is a magnetic stainless steel material. This material can be suck up by magnet. AISI 420 material is harder in surface but toughness not as good as AISI 304 material.
Furthermore, stainless steel balls (AISI 304) eliminate iron impregnation of components from the chemical interactions that take place during some finishing processes.
