Universal(TM) Burnishing Tool Achieves Finish, Reduces Down Time
Job shop was machining a six-speed transmission hub for a major automotive manufacturer. Their production requirement is some 75,000 to 80,000 parts per year. They were achieving the desired size and finish, but changing cutting tool inserts every 20 to 50 parts.Although the carbide inserts were relatively inexpensive, down time for changing the insert and re-setting the machine was costly.
A Cogsdill UBT-B1 Universal Burnishing tool was applied. The tool is used to achieve the finish requirement of 10 to 24 microinch Ra. This allows for an increase in the number of parts per cutting tool insert (now averaging 750), for reduced down time, faster production, and lower costs.
