As the technology leader in the field of mass finishing machines, OTEC develops and manufactures innovative machine concepts for perfect surface finishing. OTEC's grinding and polishing systems are made entirely in Germany and are unbeatable in terms of precision and cost-effectiveness. For over 25 years, the company's motto, "Perfect surfaces. Worldwide" has been at the heart of all its inventions and patents and the driving force that motivates the whole OTEC team.
ELECTRO FINISHING MACHINES
Electro Finishing (EF) is a highly precise process for surface treatment of metallic workpieces using an external power source. In this electrochemical removal process, the workpiece is dipped into a specific Electro Finishing Media and anodically removed. Electro Finishing is primarily used to smooth and polish surfaces. The process is particularly effective in processing difficult materials such as stainless steel, titanium, and other alloys. The application of Electro Finishing results in workpieces with a metallically pure surface, an unaffected basic structure, improved corrosion resistance, and a permanently shiny surface. Electro Finishing offers numerous advantages over other surface treatment methods. It is a fast, effective, and precise method for achieving high-quality surfaces that meet the high demands of modern industry. Therefore, if you are looking for an optimal solution for processing metallic workpieces, you should definitely consider Electrofinish.

DISC FINISHING MACHINES
Processing is carried out in an open drum (the process container) with a base plate in the form of turntable or disc. The workpieces, together with a suitable polishing or grinding granulate, are set in motion by the rotation of the disc to create a toroidal stream inside the stationary drum. The contact between the workpieces and the medium generates a very intense finishing effect which is up to 20 times more efficient than can be achieved with systems such as conventional vibrators. Only we at OTEC have the relevant know-how to finish very fine workpieces (< 0.4 mm) using our zero-gap drum system. This makes these models especially suitable for the deburring, edge rounding and polishing of delicate and intrate workpieces.
CF-SERIES ELEMENT
The new range of CF Element machines stands for high performance and ease of use. Its top-quality steel frame makes the CF Element very stable and quiet in operation.The CF Element series with its robust process drum, is therefore very reliable and extremely cost effective.The CF Element version is available for both wet and dry finishing of workpieces.
DRAG FINISHING MACHINES
In the drag finishing process, the workpieces are clamped in specially designed holders. These holders are dragged in a circular motion through a process drum containing grinding or polishing granualate. This high-speed motion generates high contact pressure between the workpiece and the media, which in a very short time produces perfect results in the form of high-precision edge rounding, smoothing or a mirror finish in a quality equivalent to that obtained by manual polishing.
STREAM FINISHING MACHINES
SF technology, also known as stream finishing, gives rise to an innovative new generation of mass finishing machines. In this process, the workpieces are clamped in a holder and lowered into a rotating container filled with a grinding or polishing medium. The actual finishing motion is generated by the grinding or polishing medium flowing around the workpiece and in addition by the independent rotation of the workpiece itself. This enables surfaces with values of Ra 0.01 to be obtained, even in the smallest chip flutes. The SF process offers very short finishing times, is easy to automate and at the same time produces highly consistent and reliable results.
