The Wenzel LH 2015 Gantry CMM is a unique machine that closes the gap between traditional Bridge CMMs, and the larger measuring volume CMMs.
The LH Gantry is a CNC controlled coordinate measuring machine with air bearings in all axes. The LH Gantry enjoys all of the attributes of the smaller LH Bridge machine, but has been configured to allow the inspection of larger and heavy parts. The ‘high drives’ of the LH Gantry also ensure maximum stability even during dynamic movements. The LH Gantry CMM showcases a monolithic design with an integral granite table removing the need for a special foundation. Due to their active pneumatic vibration damping and automatic temperature compensation, the LH Gantry is protected against vibration and thermal effects. With the optional addition of a rotary table, even large gears or other components are measured flexibly and accurately.
- The Y-axis guide-way is machined directly in the base plate, providing optimal long-term stability
- Pre-stressed, encompassing air bearings in all axes
- Active pneumatic vibration damping
- Compact HT 400 control panel with central, logarithmic joystick, "mouse function" and context-sensitive function buttons. Selectable joystick's axis assignment
- The X- and Y- guideways feature bellows protections against contamination
- High-speed-dynamic servo drives with position monitoring, combined friction power transmission
- Three-axis contouring controller with intelligent "look-ahead" function for application-optimised trajectory
- Automatic on-line temperature compensation with sensors on machine axes and workpiece
- Two-stage speed selection and variable speed adjustment (override 0-100%) in all operation modes, resulting in sensitive movement via joystick or in CNC debugging
- A motorised indexing head that mounts and re-orientates the probe repeatably to any one of 720 positions at 7.5° increments
- PH20 brings 5-axis measurement capability to touch-trigger applications on all sizes of CMM
- The revolutionary 5-axis probe system provides an extremely fast scanning speed solution with a high degree of measurement flexibility, and thus an extremely high throughput.
- Compact, module changing touch-trigger probe, which allows the use of a range of stylus configurations and extensions to access features on complex parts.
- Compact, module changing touch trigger probe particularly suitable for measuring tasks with tight dimensional tolerances for 3D free-form surfaces with longer styli.
- The most compact and versatile probe system for scanning on a global scale.
-
Passive probe, equipped with a high-resolution digital length measuring system (0.02 μm), which ensures outstanding measuring precision even when using long stylus inserts (up to 500 mm).
-
The 3D Line Scanner changes your coordinate measuring machine into the ideal machine to record and handle point clouds. Perfect for all who need to record and work on surfaces and outlines of physical objects.
