Big Kaiser EWA Boring System Compensates for Cutting Edge Wear

Big Kaiser Precision Tooling’s EWA Automatic Adjustment Fine-Boring System is a closed-loop boring system that features an intelligent, fully automatic fine-boring head. The company says that when used in conjunction with in-process measuring systems, this boring system can automatically compensate for cutting edge wear, resulting in less scrap, improved accuracy and considerable time savings.

The EWA68 boring head has a travel range of 0.866" on diameter. With the smallest insert holder, it covers the diameter range of 2.677-3.543", which means that similar-sized 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 up to 5.197". 

Integration options for existing machine tools is enabled 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 exists where the boring head adjustment is performed through manual data input into a tablet or mobile device that is used to control the boring head movement.
