Heads are universal and mount on. As the universal screw driver of rigid boring bars. Why invest in a new screw driver. When all you need is a new tip? Consider setup time involved in changing out shanks and setting tool offsets?Compare that to less than 60 seconds changing out the. Head offsets remain, so setup time for boring bars can be reduced by as much as 90%. Multiply that over days, weeks, months..... Minutes saved equals profit made. Let's face it, pocket crashes are fact of life. Most can be blamed on a worn pocket. Sometimes it may be a program glitch. It may happen when optimizing cycle time. Consider the downtime associated with the crash. Tool offsets remain in tact, which means your machine is immediately back in production. Pays you to use it. VersaBar® head pockets actually increase edge life and prevent pocket crashes. Rigid fixed-pocket bar pockets wear quickly.
The reason is unfortunately the nature of the beast. The brazing process requires the tool to be heated to about 1300º F and then slow cool.
The effect of slow cooling sacrifices hardness to a lesser or greater degree. VersaBar® heads bolt on, retaining their hardness. S a pocket wears, tiny gaps.010" manifest between the pocket and insert (often unnoticed by the operator). The gaps allow the insert to shift while in the cut. This encourages edge chipping, and size and surface finish are impacted as heat rapidly degrades the cutting edge.
This results in more offset adjustments and insert indexing. Operators often resort to s. Himming the pocket (to fill gaps), but deal with size variation, more offset adjustments, more indexing. What's the cost of the downtime and aggrivation? The insert snaps, blows out the pocket, possibly scrapping a part.....
And you need a new fixed-pocket bar? It's impossible to quantify the indirect loss which results from operators continuing to use tools with worn pockets.
But common sense tells us that a carbide insert snuggled against a soft surface is not a good thing. But operators try to avoid the downtime and cost cost associated with changing out the bar, so they nurse the bar along. As the pocket digresses, there are more.Offset adjustments, more indexes, more chipped edges and finally...... Maximum versatility, reduced setup costs, reduced downtime and extended pocket life are all compelling reasons to choose. Send us your worn and crashed fixed-pocket bars and we'll retrofit them to accept modular V. ErsaBar® - the tool that. Pays you to use it!
