Vision sensor system inspects workpieces
An intelligent vision sensor system can be used without additional peripheral devices for practically all tasks in industrial image processing, including the inspection of workpieces.
The company that will show the first products resulting from the cooperation at Machine Building 2008 The intelligent Vision Sensor SRV is a development by Vision and Control from its Camat series of products

'Collet jaw' chucks offer greater versatility
A 'collet jaw' chuck is more universal than either three-jaw chucks or collets and covers a greater diameter range than conventional collets thus increasing flexibility and cost effectiveness.
Zero-point clamping system reduces work resetting
Universal zero-point clamping system that provides accurate and repeatable set-ups of workholding fixtures allows workpieces to be moved through multiple operations with minimum resetting.
Schunk has recently entered a strategic partnership with Vision and Control.
Schunk will show Vision and Control at the UK's Machine Building 2008 exhibition in Birmingham.

Magnetic clamping offered for machining jobs
A versatile magnetic clamping system is offered as work holding for rough or fine cutting applications in a variety of machining tasks on milling machines and machining centres.
It can be used for practically all tasks in industrial image processing, including the following.
* The inspection of workpieces.
* Completeness checks in assembly automation.
* Searching for parts or positioning axes and angles.
The SRV vision sensor for industrial image processing completes numerous image processing tasks without any additional peripheral equipment.
For example, it can check mechanical components such as pins, rings, nuts or bolts if they are present.
The SRV performs assembly and feature checks, recognizes damage on edges, detects the position of fastenings and labels, sorts and removes defective components.
In pick and place applications, it ensures that parts in all kinds of rotary positions and even limp objects such as cables and hoses are safely gripped.
In addition to the camera and lens, the compact housing of the SRV also accommodates LEDs and an evaluation unit with all the necessary software and interfaces.
In the simplest case, you only have to connect the sensor to a power supply and teach it using two keys.
After the teach-in process, the sensor sent signals whether or not a part is present and the position (X, Y, angle).
In this way, the user does not have to program the application first and can start working immediately.
Consequently, even inexperienced users can intuitively find their way to an image processing solution in just a few minutes.
The SRV sensor offers a high resolution of 720 x 480 pixels (W VGA) and a frame rate of 60 frames/s.
Alongside the SRV, Schunk will be introducing the new size 60 Beta series of linear axes at the Machine Building 2008 exhibition, thereby providing even finer graduation in its program of precise linear modules.
An important prerequisite for selecting the best axis solution in terms of cost and performance, said Schunk to manufacturingtalk.com, the Size B 60 is intended for economical axis applications with high demands on dynamic and smooth running.
The 60 Beta series of linear axes features a precise profiled rail guide and can be operated both by a ball-screw spindle drive with supports and by a robust, play-free toothed-belt drive with adjustable belt tension.
As the ball screw drive and the profiled rail guide have been generously dimensioned, Schunk said that size B 60 is a real 'bundle of energy' with an amazingly small profile that is characterised by high load-bearing capacity and a long operating life.
The version with ball screw drive is designed for a high driving force of 4,000N and attains travel speeds of up to 2.5m/s with a maximum stroke of 5120mm thanks to the spindle supports.
Acceleration values of up to 20m/s2 are possible with a repeat accuracy of +/-0.03mm.
By comparison, the version with toothed belt drive attains a high driving force of 850N and covers distances up to 7620mm at speeds up to 5m/s.
The maximum possible acceleration is 30m/s2 with a repeat accuracy of +/-0.08 mm.
* Polyamide gripper fingers and adapter plates - also to be shown at Machine Building are new polyamide gripper fingers and adapter plates.
Manufactured in a laser forming process by LMD, a technology partner of Schunk, the components feature very complex geometries that cannot be produced by metal cutting technologies.
The complex air feed-through can be routed through a one-piece workpiece in all three dimensions without having to set bore holes from the outside.
As a result, adapter plates with complicated internal channels can now be produced as a single unit without drilling.
This gives customers gripper fingers of any design for form-fit gripping within just three working days, said Schunk to manufacturingtalk.com.
Since the used polyamide is very elastic, laser forming is also excellently suitable for one-piece compensation systems that adapt to the shape of the workpiece using oscillating suspended gripper jaws.
With polyamide gripper fingers, it is also possible to grip sensitive and thin-walled workpieces, such as car body parts without clamping marks or other damage.
For further details on any of these products please come and visit Schunk at Machine Building 2008.
