EWN precision boring bar, diameter 20-510mm

EWN precision boring bar – range 20–610 mm

Series precision boring bars

EWN

is a tool system for accurate boring of holes in the diameter range from

20mm to 610mm

. These tools are characterized by an adjustment scale

0.01 mm in diameter

, which allows extremely precise adjustment of the dimension without the risk of losing the setting after tightening the mounting screw.

Thanks to its stable structure and precision of workmanship

0.005 mm

, EWN boring bars allow for machining requiring the highest repeatability.

Scope and modular structure

Available in sizes

20–610 mm

, which allows you to select a tool for almost any industrial application.

Boring bar adjustment co

0.01 mm in diameter

.

Possibility

lengthening

tools using adapters and adapters (LBK systems), which gives an advantage over competitive boring bars

Service both

traditional boring

, as well as

back boring

.

Applications

Machining of holes requiring high accuracy and repeatability (bearing seats, bushings, body elements).

Particularly useful for

very long holes

, where the ability to extend the tool is crucial.

Benefits for the user

Dimensional stability

– after tightening the mounting screw, the dimension does not change, which allows for precise compensation.

Flexibility

– one system covers diameters from 20 to 610 mm.

Possibility of adaptation

– thanks to the modular structure, you can use various legs, adapters and adapters.

Precision of workmanship

– manufacturing tolerance up to 0.005 mm.

FAQ
