Mobile, CNC Laser Scanner solution
MobileScan3D is a mobile CNC laser scanning solution allowing fully automa-tic reverse engineering and part inspection verification. Its portability and rapid setup provides a unique opportunity to scan on location, without the tedious and time consuming effort required by other portable scanners.

MobileScan3D, comprised of a 2-axis CNC swivel head, provides A and B rotational axes. The MobileScan3D laser scanner system consists of a tripod with three interchangeable scanning heads: a 100mm to 290mm head with accuracy of ±0.01mm; a 400mm to 570mm head with accuracy of ±0.05mm; a 1,000mm to 1,800mm head with accuracy of ±0.15mm; and an average line length of 43mm, 185mm, and 270mm, respectively. The scanning sensor swivel head mount uses a quick change adaptor to minimize changeover time.

This system has full 3-axis CNC capability and uses a red laser stripe to scan up to 100,000 points per second.  Scanning accuracy down to 10µ can be achieved with the system. The density of scanned lines can be controlled by programming the velocity of the A and B axes of the swivel head. Integral thermal sensors, with environmental control, insure scanned data set accuracy.

Advancing ECM to PEM
The PEM (precision electrolytic machining) Process is an advanced, highly accurate metalworking technique based on electrolysis. The result is precise shapes with excellent burr-free surface finish, some as low as 1μ to 4μ Ra. This technology generates highly-complex geometrical shapes that cannot be efficiently manufactured using conventional chipping making processes.

The specific advantages of PEM-machined workpieces offer an extensive range of possible applications in a variety of industries including medical, automotive, aerospace, tool & die, diesel, fluid power, and control.

PEM is an advance in electrochemical machining (ECM) that incorporates pulse power and an oscillating cathode tool. In ECM, metal is machined in a non-conventional manner through the use of electricity and chemistry to quickly and accurately dissolve metal and produce the desired end product.

The PEM process is a precision electrochemical metal removal technology using vibrating electrodes and a regulated working gap of typically 10μ to 20μ. With the innovative, PC-based PEM machine, a pulsed direct current is applied between the electrode (tool) and the anode (workpiece). As electrons cross the gap during the pulse, material on the workpiece is dissolved in accordance with the geometry of the tool. This gives rise to complex geometrical shapes in practically all metals.

Endmills for Exotic Alloys
Niagara Cutter has developed endmills specifically engineered to meet the new and developing challenges of the aerospace industry. Airframe manufacturers are faced with new challenges of machining exotic alloys and CRPF’s (carbon reinforced polymer fibers). These materials are stronger and lighter than previously used materials and Niagara Cutter has answered these challenges with specially engineered tool geometries combined with CVD diamond coatings to deliver unprecedented resistance to tool wear in abrasive CRPF materials. If your workpiece is titanium, such as 5553 and 6AL4V, the patented Niagara Cutter Stabilizer – with its variable geometry design and engineered PVD coatings – has proven to increase milling efficiency.
