Ultrasonic cutting

Ultrasonic Engineering Ltd: Ultrasonic Engineering has developed a technique for cutting a variety of foodstuffs such as, gateaux, confectionery, cakes and pizza. The process produces little crumb and gives a clean-cut as the ultrasonic system utilises a titanium horn shaped much like a conventional knife. One of the many advantages of using this cutting technique is that the knife is self-cleaning due to the ultrasonics which are transmitted from the generator

Olympus America Inc.: Converting ultrasonic vibrations into energy, SonoSurg scissors minimize bleeding by coagulating as they cut tissue. Simultaneous coagulation and cutting means procedures can be performed quickly. Coagulation is performed at a low temperature without delivery of electrical current through the patient's body.

Power Ultrasonics: Imagine a knife which moves itself backwards and forwards in a sawing action, thirty thousand times a second. True the distance moved is very small but the acceleration is so high that nothing can move with the blade or stick to it. Ultrasonic scalpels are used by surgeons where they want to cut without exerting any pressure. In industry ultrasonic cutting tools are used for products that are difficult to cut by other means. The heat generated by the ultrasonic vibrations can also be useful. Some man-made fabrics are cut and simultaneously sealed using ultrasonic knives to prevent fraying.

Alex Corporation: Alex ultrasonic cutter "KW-430C" is a general purpose portable cutter which can cut plastic parts and fablics smoothly. The cut edge is smooth and beautiful because of ultrasonic vibration.An operator only handle the probe and step the foot switch. So, anybody can use easily this ultrasonic cutter.

ROTECH TOOLING SWEDEN: Your nimble and forward-looking supplier of robot arc welding, robot spot welding and ultrasonic cutting equipment and turnkey solutions.

Fischione Instruments, Inc.: Ultrasonic disk cutting is a proven method for producing TEM specimens from hard, brittle materials, such as ceramics, semiconductors and geological materials. This rapid technique directly produces disk specimens from materials as thin as 40 mm, cylindrical rods up to 10 mm in length from bulk samples, or rectangular wafers which are subsequently used in the preparation of cross-section TEM (X-TEM) specimens.

GEISS AG: According to requirements, we offer our CNC trimming machines with an ultrasonic cutting unit in place of the milling spindle: either as a single-purpose ultrasonic cutting machine, or with a second Z axis as flexible production cell.The ultrasonic cutting technology has indeed a promising future for its precision is far superior to conventional milling. Nowadays the ultrasonic cutting unit, that operates without swarf and noise, is predominantly used for materials that are difficult to be processed or even not at all with a milling spindle.

Gatan, Inc.: The original disc cutter for TEM applications, introduced for cutting 2.3mm and 3mm discs from brittle materials such as ceramics, semiconductors and minerals.A variety of cutting tool sizes (0.1mm to 10mm) and shapes (circles, squares, rectangles, etc.) has expanded its use beyond microscopy applications (cut holes or cut shapes). Cutting is achieved through a piezo crystal driven Titanium tool in conjunction with a water-based slurry of boron nitride. The gentle action of the cutting tool combined with a constant tool load provided by the action of the pivoting platform reduces or eliminates stress and chipping around the cutout or the cut piece. Sample thickness can range from 30µm to 5mm and the depth of cut is continually displayed on a dial indicator (10µm resolution).A microscope and positioning table (Optional) can provide precise cutting at a specific point on the sample surface. A primary application is precision TEM specimen preparation of materials, i.e. Semiconductors.

Misonix Inc.: In October 1996, Misonix enetered into an exclusive twenty-year license agreement with US Surgical (USS), a subsidiary of Tyco International Inc. for the worlwide right to sell amd market our ultrasonic cutting and coagulation system. The Auto Sonix TM uses high frequency sound waves to divide and coagulate tissue for both open and Laparoscopic surgery. The partnership with USS is an important one to Misonix and demonstrates the value of our ultrasound technology. Our company continues to improve the product as well as develop new products all designed to enhance application, performance and utilization.In 2002, the technology was upgraded and is being well-accepted by the customers.

Maschinenbau u. Konstruktion GmbH Elmshorn: The blade cuts layers up to a thickness of 8 mm at a frequency of several kHz and with an amplitude of only a few µm. The cutting speed is up to 60 m per minute. The accuracy of edge cutting is only a few tenths of a millimetre. The machine is controlled by a Siemens CNC continuous path control. Older cutting software can be used by means of an integrated postprocessor. The MuK ultrasonic cutter also cuts leather, paper, rubber and many more synthetic materials.

Branson Ultrasonic Corporation: Branson Ultrasonics has been cutting food products since the early 1970's. Back then we cut things such as Napoleon snacks, and we even tried to shuck oysters. We used ultrasonic blades sharpened on one side attached to a hand-held device. Today, Branson has food manufacturing customers all over the world cutting products such as cakes, pies, granola bars, cheese, pizza dough, confectionery products, bread, gum, candy and even licorice. Clean cuts through multiple layers produce visual appeal. Fillers, such as nuts or raisins, are cut cleanly and produce less fragmentation than with conventional cutting methods. Depending upon the type of product, ultrasonics can even be used to reshape and reform. Advantages range from increased blade life to cleaner product cut surfaces, to the most important: reduced down time for cleaning.

Hielscher - Ultrasound Technology: Ultrasound-supported cutting and welding offers remarkable advantages compared to commonly used processes. The necessary cutting forces are reduced by approx. 75%. The cutting speed and the related productivity of the cutting process are considerably increased. In contrast to the thermal processes, during the ultrasonic welding the sonotrode remains cold, which augments the bonding quality and cycle period. Dr. Hielscher GmbH has specialized in the continuous cutting, welding respectively in the combination of both cutting and welding of films and plates. Materials such as textile, plastic, glass and coal fibers, paper and cardboard or rubber composites are successfully cut or welded. Bonding techniques such as the welding of plastic parts, heating of adhesive glues, closing of plastic-coated containers, crimping, punching, etc. are also offered. When using our ultrasonic processors, different tools for the corresponding tasks as well as new patented solutions assure an economical and high quality.

Spectrum Robotic Systems Ltd 1999: The 2001 series is extremely useful when processing materials where traditional methods fail. A good example is pre-preg kevlar. A cold, dry method of cutting is required to cut this incredibly strong, sticky material. Ultrasonic cutting will process this material without burning, delaminating or otherwise degrading the material. All controls are automated, position, height and steering of the blade.

TELSONIC ULTRASONICS: Using the TELSONIC Ultrasonic Cut'n'Sealing system simultaneous cutting and edge-sealing of a wide range of materials and shapes is possible. Research and the development of special control features, tooling material selection, heat treatment and FEA design have proven to be key factors in achieving manufactured product consistency, reliability and cost effective processing techniques.

Dukane Corporation: Dukane Ultrasonics food processing uses high-frequency sound vibrations to process food products faster and eliminate most of the downtime caused by the continual cleaning of conventional cutting blades. Ultrasonic equipment provides a new way to cut, slice, divert, align or transfer a variety of food products that streamlines production, minimizes product waste and lowers maintenance costs.
