The 537052 Boring Cassette is now available with 3E Tech for micro precision adjustment range measurement in the Asian and European markets.

Bengaluru, India - Wohlhaupter India Pvt. Ltd. provides engineering, technical support, and onsite application services within India for Wohlhaupter GmbH and Allied Machine and Engineering Corp., leading manufacturers of holemaking and finishing tooling systems. Together, they are excited to announce the expansion of digital tools offered with external 3E Tech digital display for micro precision adjustment range measurement. The company is successfully converting a series of precision boring tools with built-in digital displays to include 3E Tech.

3E Tech combines precision adjustment measurement in the tool with an external, dockable and detachable digital display that shows the adjustment setting. This simple, micro-precision readout capability facilitates reliable machining processes for high-precision components. A sensor unit fitted to the display makes direct contact with the tool to record the adjustment travel. Wired, Bluetooth, or magnetic connections are not required.

As of January, the 537052 precision boring cartridge is equipped with 3E Tech. Made of hardened steel, it is extremely robust and resistant to all external mechanical influences. It can be used on all serrated tool bodies and Alu-Line slide tools in the diameter range from 100 mm to 3255 mm. Alternatively, this precision boring tool can be adjusted without the aid of the display. Its diameter can be set via a vernier scale, also in 2 µm increments. This new tool offers an excellent price/performance ratio with extreme accuracy and robustness. A simple version without 3E Tech (537051) rounds out the range in this price segment.

External display compatible with all Wohlhaupter tools

The 3ETECH display unit docks onto the tool and is activated via a pushbutton. It then shows the relative adjustment value of the tool in 2 µm increments of the diameter to enable high-precision boring. Because the display attaches externally and is not built-in, it can be used with all Wohlhaupter tools that are equipped with 3E Tech sensor units. The external display is particularly suitable for tools having a small body diameter, and for special tools with one or more adjustment units.

Detaches safely if spindle starts unintentionally

Built-in displays can get damaged during the machining process, and solutions that are fastened to the tool by magnets can lose the setting value if contact is broken. Not so with 3E Tech as the measured values are stored in the tool itself to prevent data loss. The patent-pending interface between the digital display and the tool ensures safe detachment in the event of an unintentional spindle start and protects the operator if the display is inadvertently left on the tool.

"From now on, all our tools from the smallest to the largest diameter will be equipped with 3E Tech, and it will be optionally available on special tools. The great success of the digital display has virtually forced this decision on us," says Managing Partner Frank-M. Wohlhaupter.

"The external solution may be a little more expensive for a single tool, but it soon pays for itself when used with multiple tools. Likewise, for special solutions with multiple cutting edges that are read via the same display," says Axel Wagner, Business Development Manager at Wohlhaupter GmbH.
