Big Kaiser's EWA68 Boring Head System Compensates for Tool Wear
IMTS Spark: Big Kaiser Precision Tooling’s EWA68 closed-loop boring system features an intelligent, fully automatic fine boring head.
Big Kaiser Precision Tooling’s EWA68 closed-loop boring system features an intelligent, fully automatic fine boring head. This system, when used in conjunction with in-process measuring systems, can automatically compensate for cutting edge wear, resulting in less scrap, improved accuracy and time savings, the company says.
The EWA68 boring head has a travel range of 0.866" on diameter and covers a diameter range of 2.677" to 3.543" with the smallest insert holder. This means that similar-size bores on the same part could be produced with a single boring head. With the addition of two larger insert holders, the diameter range can be extended to 5.197".
Integration options for existing machine tools is accomplished with the use of an external industrial PC to handle the machine control communications and EWA boring head adjustment. Newer machine tool controls may be suited to handle the EWA software directly to achieve more seamless integration. For lower-level integration where in-process gaging is not present, a third option for implementation performs the boring head adjustment through manual data input into a tablet or mobile device that is used to control the boring head movement.
