Allied Machine Exapnds Wohlhaupter Boring Tools Offered with Digital Readout

The 538 (537) Boring Cassette with 3E Tech is now available.

Allied Machine and Engineering, a leading manufacturer of holemaking and finishing cutting tools for the metal-cutting industry, announces the expansion of Wohlhaupter digital tools offered with an external 3ETECH digital display for micro-precision adjustment.


3ETECH combines precision adjustment measurement in the tool with an external, dockable and detachable digital display that shows the adjustment setting. This user-friendly, 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 June, the 538052 (537052) precision boring cartridge is equipped with 3ETECH. Made of hardened steel, it is extremely robust and resistant to all external mechanical influences. It can be used on serrated tool bodies and Alu-Line slide tools in the diameter range from 3.937" - 128.15" (100 mm - 3255 mm). Additionally, this precision boring tool can be adjusted without the aid of the readout. Its diameter can be set via a vernier scale in 0.0001" (0.002 mm) increments. This new tool offers an excellent price/performance ratio with extreme accuracy and strength in any industry. A simple analog version without 3ETECH compatibility 538051 (537051) is also available.

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 0.0001" (0.002 mm) increments of the diameter to enable high-precision boring. Because the readout attaches externally and is not built-in, it can be used with all Wohlhaupter tools that are equipped with 3ETECH 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 readouts can get damaged during the machining process, and magnetized solutions can be susceptible to data loss if the contact is broken. However, 3ETECH provides the capability to store measured values in the tool itself to prevent data loss. The patent-pending interface between the digital readout 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.

"The new Wohlhaupter 3ETECH 538 (537) cassettes provide the ultimate combination of convenience and versatility—the perfect solution for your large diameter precision boring applications," shared Natalie Wise, product manager.

Dynatect Automated Machine Safety Roll-Up Doors

Need to increase safety? Are you using light curtains? Is space a concern? Dynatect's Gortite® VF Automated Machine Safety Door combines safety technology, speed, and a physical barrier to isolate hazardous operations. Use of a physical barrier with safety sensors can save up to 30 square feet of manufacturing space. Using the ANSI minimum safety distance formula, the Gortite® VF Door limits the depth penetration factor and average approach speed, allowing closer location of the safeguarding device. Unlike light curtains, which can't contain process hazards, an automated machine safety door can isolate common workplace debris. This physical barrier is designed to contain process driven hazards such as weld sparks, UV flash, and light debris. Thus, the operator can maintain closer proximity to the work area improving ergonomics and productivity.
