Punching dies, like all other punching tools, must meet high demands. A punching die’s surface quality is essential for smooth and efficient stamping, which is why the surface processing methods for these tools are constantly being refined. OTEC offers stream finishing machines and process technology for efficient and optimal surface processing of punching dies.
Skiving cutters are used in the production of gear wheels. When producing gear wheels, the desired geometry is achieved by a process known as gear skiving, which combines the two traditional processes of gear hobbing and gear shaping. Skiving offers a high degree of productivity and flexibility, and compensates for the drawbacks of the two […]
During the manufacturing of metal workpieces it’s often necessary to machine threads. Usually when workpieces have to be mounted or assembled to other parts, screw connections are unavoidable. Generally, there are two different ways to create threads: cutting (‘taps’), which is the most popular method, and forming (‘forming tools’). OTEC has developed several surface finishing […]
Cutter bodies such as drilling, milling and rotary bodies are used for machining processes and serve as holders for inserts. Cutter bodies are available in different lengths and shapes and are manufactured of hardenable steel from which the cutter body is first milled, then deburred, hardened and ground to size. Finally, the polishing or coating […]
OTEC’s stream finishing machines can be used for a range of applications and industries but they offer unique advantages for the toolmaking industry, particularly for edge rounding on carbide tools. Edge rounding or honing carbide tools is a common process that helps extend tool life and improves PVD coating adhesion. Rounding and smoothing the cutting […]
In the automotive industry, the surface finish of individual components is crucial. So-called bulk goods are typically finished using disc finishing machines whereas sensitive parts that need to be finished to a greater degree of precision require the use of stream finishing or drag finishing machines. At OTEC, we offer a variety of finishing machines […]
OTEC is expanding its SF Series of stream finishing machines, with the addition of the SF-HP model, designed to accommodate larger and heavier workpieces. With its modern and compact design, the SF-HP was developed to round edges, polish, smooth and deburr large workpieces. This innovative machine can be used for applications across a variety of […]
According to WebMD, knee replacement surgery is one of the most common bone surgeries in the United States. As knee replacement surgeries become more common, there is more demand for the artificial joints used for these procedures. OTEC’s stream finishing machines are highly effective for deburring, rounding, smoothing and polishing axially-supported knee prostheses, a frequently-used […]
OTEC’s stream finishing machines can be a reliable, quick and cost effective alternative to manual finishing for the aerospace industry. Stream finishing can be used with servo valves, which are commonly used in aircraft flight control systems. These valves hydraulically operate aircraft ailerons, rudders and other control surfaces. High friction and burr formation among a […]
