EWA Flow Chart

With the EWA Automatic fine boring head, there is no need to stop the machine tool to take measurements and manually adjust the boring tool.

THE FUTURE OF MANUFACTURING EWA AUTOMATIC FINE BORING HEAD

With the BIG KAISER EWA, there is no need to stop the machine tool to take measurements and manually adjust the boring tool.

START

ETHERNET

Preset EWA to target boring size on presetter

SKIP SIGNAL

EXTERNAL COMPUTER

Load EWA into machining center and cycle start

EWA BORING HEAD

OPT-2500 TOUCH PROBE

MACHINING CENTER

FULLY AUTOMATED

Tool change to touch probe, measure dia. of existing hole

Bore hole with EWA boring head

Computer commands EWA to adjust by calculated value

YES

Calculate adjustment value using predefined deflection data

Is it the first time the EWA is boring the hole?

Is hole less than the target diameter?

YES

Is hole within tolerance of target diameter?

Is there still enough stock allowance on workpiece?

Tool change to EWA boring head

YES

Machining finished based on operator specifications

No further machining required

Hole is larger than target. Generate alarm

END

- Reduce cost - Handle Multiple and Repeat Bore Sizes

- Improve Accuracy - No Manual Wear-Out Compensation
