OTEC Machines

Engineered in Germany, OTEC machines deliver flawless, mirror-like finishes with unmatched speed and consistency. They automate tedious bench labour and protect delicate jewellery geometries across every batch.

OTEC Machines

OTEC CF 3x18

The CF -series of disc finishing machines can be used for any application that requires a perfect surface finish to be achieved in a very short time for a variety of workpieces such as in cutting, turning, milling and stamping tools, jewelry, etc. 

Disc finishing machines are modular in design and available as standard with 1 - 4 process drums.

 All controls are accessible from the front and clearly laid out. Many years of experience have gone into the development of these machines, which is why they are so popular with our customers.

Standard Equipment

  • Process drums with hot moulded PU lining

  • Aluminium profile chassis - easy to add on optional equipment

  • Speed control via frequency inverter

  • PLC touch screen control unit / 2D control unit (for the jewelry industry) with digital display of processing time, speed, rinse cycle, dosing and other key process parameters and storage for up to 75 different finishing programs.

Underlying Technology

The difference between the centrifugal forces acting on the workpieces and the process medium creates a very powerful finishing effect. This can be up to 20 times more efficient than, for example, conventional vibrators.

With wet finishing, a water/compound mixture flows continuously through the system, rinsing away the fine particles of debris from the finishing process.

This gives the workpieces a clean and corrosion-free surface. Many years of experience have been channelled into these machines, making them very popular with customers.

Ceramic Gap System

With this system, the gap can be set to an accuracy of 0.05 mm since it is formed by using two ceramic rings made of SIC. this technology is best suited to dry finishing since it enables best results to be obtained by using very fine polishing granulates.

Ceramic/Polyurethane Gap System

This standard system from OTEC is suitable for the most common applications in wet finishing. The cermic/polyurethan combination prevents any workpieces from becoming lodged in the gap area, making the process very reliable and reducing maintenance requirements.

Unique Zero Gap System!

For the wet finishing of very fine workpieces. The gap between the rotating disc and the stationary drum can be reduced to zero. This enables very fine grain abrasive media such as quartz to be used and prevents any workpieces from becoming lodged in the gap.

Accessories

Dosing

Dosing unit: Dosing unit for automatic preparation of the water/compound mixture with automatic rinsing. Concentration of compound can be set via the control unit. The water flow is indicated on the control unit.

Dosing pump: with suction nozzle and automatic cut-out when empty

Dosing unit with electronic preselection: dosing unit with electronic preselection of compound concentration and water flow.

This dosing unit enables not only the compound concentration but also the water flow to be precisely defined via the control unit. In addition, the water flow rate and the compound concentration can be flexibly programmed during the process.

Separating

Manual separating unit: using a manual screen (Image: CF 50)

Manual screen: available in a variety of sizes

Automatic separating unit with magnetic drum: for ferromagnetic workpieces, optionally available with integrated demagnetization and/or fine grain separation.

Unisepa: automatic separating unit using a screen machine with a vibration motor. Extremely efficient. Fast and user-friendly screen change. Vibration speed can be set by mens of frequency inverter.

Miscellaneous

Rinse system: prevents the workpieces from ahering to the edge of the drum, thereby ensuring that all workpieces are processed

Hopper

Tray system: system for storing additional plastic containers for media

Trolley for benchtop unit: for storing additional granulate collecting containers, paste and compound containers

Why Choose the OTEC CF 3x18
