The Antares 700X is a CNC machine equipped with X-Ray vision system for the optimized execution of the tooling holes and any other mechanical reference on multilayer panels and inner-layers.
The granite base, linear motors, optical linear transducers, high resolution X-ray camera and compact drilling head give the best thermal stability, high accuracy and positioning speed, with wear and maintenance practically absent over time
Typically the reference holes are used to inset pins, which will be used to clamp the panel with the accurate alignment to the X, Y axes of the drilling machine. To this aim, the reference holes must be executed with best optimization respect to the inner lay-up of the multi-layer panel.
The process to drill reference holes is made in two steps:
1) In the first step the machine will detect the centers of those targets that have been chosen to represent the internal lay-up. The enlargement/shrinking, due to the previous pressing process, as well as the registration errors are considered.
2) In the second step the programmed holes will be executed in optimized positions based on the detected topography, but at a definite reciprocal distance, as required for pins. The drilling is performed by a pneumatic spindle using a standard drilling tool with ring. (The rotation speed is fixed at 30.000 rpm.) The panel is clamped by vacuum area at the center of table. The table is made by a material that is X-Ray transparent and offers the possibility of inspecting any kind of panels or PCB's in any point, including the vacuum area, which is also X-ray transparent.
ADVANTAGES:
- High flexibility: Arbitrary number of Targets (min. 2) and holes;
- Optimised hole drilling (geometrical error of the board is included into hole position calculation);
- Fast cycle time;
- Also useful for measuring panels only (measuring data can be easily exported);
- Very userfriendly software;
- Automatic unloading system of panels outside specification;
- Full Automation Capability;
