Quality inspection - Import export

Particular Challenges: In the course of the production, endless cables are running at a considerable speed, and supervision has to be carried out nearly under real-time conditions. The size of the objects to be determined, i.e. of the flaws to be discovered, is in the range of only some hundredths of a mm. Another difficulty is the fact that surfaces with very different reflectivity and roughness are involved. In order to be able to check the cables all around, several laser scanners must be in place, mounted at different angles, thus covering the entire range of 360°. Quelltech Solution: The solution consists in a configuration of four Q6 laser scanners, mutually displaced by 90°, so the entire surface of the cables is in the field of view. On the basis of the 100% inline inspection, the position of defects can precisely be determined, without losing too much time.

Particular Challenge: For the assessment of rotating parts, numerous parameters have to be taken into consideration: Concentricity, radial run-out and axial run-out (i.e. wobble); furthermore thickness, diameter, planarity and the absence of surface defects had to be examined. The solution developed by QuellTech consists in a configuration of three Q6 Laser Laser Scanners.Each of the lateral surfaces is assigned to its own scanner. In order to enable the thickness precisely to be determined, both laser lines are mutually oriented in opposite direction. The third scanner inspects the outer circumference of the wheel, this way measuring diameter and radial run-out. All of these scanners are subject to encoder signals supplied by the rotary axis and synchronously triggered, so possible defects on the wheel can precisely be localized. The measurement takes place at a resolution of ca. 30 µm, and a cloud comprising several millions of points are obtained.

3D laser scanners for inline quality inspection The scanCONTROL 3D scanners are used for inline 3D scans with high accuracy.

This special Metzner development is able to process cable wires with a diameter of up to 28 mm. The cycle time for this is 2000 mm / 35 seconds. The processing steps include long slitting, sawing, circumferential cutting, stripping, brushing and depositing. An integrated ink jet printer labels the cable wires with information or markings. As the heart of the processing method, Metzner uses a newly developed stripping head that combines a rotary cut with a powerful clamping and simultaneous rotation of the material. This enables a high-precision, multi-stage radial cut through the various layers of material. Microscopic quality inspection confirms that the processing is flawless with no scratches, pressure or abrasion marks. In addition to the high machining quality, the machinery also offers special precision: both the overall length and the machining position are maintained with an accuracy of 0.2 mm. The machine can process cable wires with diameters up to 28 mm.

Vibrating tables suitable for testing and quality inspection of sensitive components The vibratingsystems are employed for simulation of stress created by mechanic vibrations on mechanical and electrical components and subassemblies with the following features: Direction of oscillation: linear - horizontal (sinusoidal oscillation), adjustable by means of a selector. Either oscillation in x-axis or alternatively in y-axis

Inspection of Surfaces 2D and 3D Regarding surface quality inspection for metal products such as cylinder head, gear tooth, it consumes a lot of time and human resources for the inspection. Since parts are inspected by bare eyes or slow speed inspection machines. With the inspection machine HE1000, inspection is much faster, more accurate and fully automated. In addition, there is a 3D laser sensor combined with our 2D inspection head to provide the most accurate result. This sensor is the first in the world to apply the Nobel Prize winning physics technology of optical frequency combs. It utilizes coaxial lasers and high precision range finders. There are some cases that our customers reduced over 90% of the inspection time. urthermore, if parts are inspected by humans, there might be different results by each person, because each of them has a different tendency and criterion.

Visual Inspection of Surfaces This SE1000 Visual inspection measuring machine has been developed to automatically inspect the appearance of dirt, scratches, and other imperfections on various kinds of surfaces of your product. This 2D inspection technology can be used in production lines and is suitable for all kinds of industries that want to improve quality, reduce human involvement in inspection and reduce inspection time. Leveraging this fast, precise inspection machine will help you to improve the quality of your product dramatically.

All components pass a quality inspection before being used. Many different methods and procedures are used here (e.g. PMI 0 positive material inspection, crack detection). Our scope of machining reaches from chipping/metal cutting to sandblasting (using granule materials) to welding, assembling and painting. We handle many different metallic and nonmetallic materials as steel, stainless steel, duplex materials, titanium, plastic material We give a big importance to welding: Nash employees are certified according to ASME 9 and therefore qualified to manufacture pressure vessels and piping according to Pressure Equipment Directive (DIN EN 3834) and ASME Standards (31.3). Our systems are painted according to customer specification. We work with all wet paints and 2K paints. Anti-corrosion-coatings up to category C5M are possible. Of course, we meet all the other specifications, e.g. regarding coating thickness, as well. The electrical engineering is also done in the Nash location, from design to cabling. After the completion, the system undergoes a pressure test. Furthermore there is an option to do a complete function test to verify the performance data. Nash is certified according to ISO 9001 and ISO 14001.
