-
- Processing of deep holes with different diameters
- Surfaces with a roughness of Rz < 1 µm are produced quickly
- Long lifetime for wear parts
- Chipless and quiet process
- Processing up to front surface possible
- Wear parts can be exchanged quickly
- Barely any lubricant / cooling required
- Can be used on almost every machine
- Stepless adjustment of roller force
- Roller force can be determined easily

Description
WENAROLL ERGI roller burnishing tools are designed to process cylindrical holes with greater depth and varying diameter.
ERGI-1 is suited for holes with a diameter greater than 35 mm, ERGI-2 is designed for diameters greater than 52 mm.
ERGI-1 Inner work piece diameter > 35mm
ERGI-2 Inner work piece diameter > 52mm
Tool structure
The Wenaroll Single Roller Burnishing Tools type ERGW consist of a tool body with a detachable roller mount, as well as a tool shank suited for your application.
The tool has a site mounted dial indicator, which displays the spring deflection. With the provided chart you can adjust the roller force to produce the surface you need.
Process
All metal materials up to a yield strength of 1400 N/mm² and a maximum hardness of 45 HRC can be process with this tool. During the process the work piece must rotate, a tool rotation is not possible.
Operation is possible on all kinds of production machines conventional as well as CNC. The force required for a successful burnishing operation is provided by the machine axis and is precisely adjusted with an indicator dial.
The lubrication required can be provided by the machine, with either oil or emulsion as lubricant. The circumferential speed of the tools can go up to 150 m/min , the feed can vary between 0,1 mm/R and 1 mm/R.
