Design

The baseplate, the linear axis guides and the counterhold are made of hand-lapped granite ensuring identical thermal behavior of the complete measuring system and long term accuracy.

For highest precision, air bearings are used in all linear axes.

High accuracy pneumatic or hydraulic rotary tables with a range of load bearing capabilities are offered, ensuring precise and fast rotary motion of the gear during inspection.

Ultimate Precision and Flexibility

Gears constantly contact and mesh with other gears and most often run very quickly. If gears are not manufactured to the required standard they can wear quickly, fail to deliver the correct power and can even break.

Machines built for gear inspection must perform to a higher specification than the machines used to manufacture them. All WGT machines are accurate to VDI/VDE 2612/2613, Group 1.

WGT machines are applied all around the world for large and small gearboxes and shafts, in the automotive, aerospace, power generation and other important industries.

System

The WGT machine is not the solution, it is part of it. Our applications team study exact customer needs and configure a system to meet those needs.

These options include increased Z-axis movement and taller counterholds to accommodate longer shafts, different rotary tables to carry the right part weight and a probe changer with the right number of ports to automatically handle the styli needed to support production.

LHInspect gear software

LHInspect is a sophisticated software solution used in combination with the measuring devices of the WGT series for the measurement and inspection of all type of gears, gear cutting tools and shaft-type workpieces, including determination of form and position.

In addition, the software offers the possibility of exchanging geometry and measurement data between gear inspection machines and gear cutting machines, using the seamlessly integrated manufacturer neutral GDE Interface, in order to enable the automated correction of machine parameters.

The WGT gear inspection machines with LHInspect are characterized by their ease of use and user friendliness, which are based on decades of experience in gear measurement technology.
