Machine LDT/1000.
Special machine to polish small items made of brass, steel, Plexiglas etc, such as pipes, caps, rings etc. The pieces can have a length between 50 and 1000mm.
The first working piece is clamped between 2 live centers (mounted on a 3 position dividing table). At every rotation of the dividing table, a piece (situated into the load position) moves to the first working station (rough machining), where it starts turning; the piece in the first working station moves to the second one (finishing), while the piece situated into the second station returns into the load position, than it is picked up and replaced with a new working piece. Each working group is equipped with 2 slides, the one allowing the approach of the polishing brushes to the piece, the other allowing the longitudinal sliding of the brushes in the 2 directions. The working cycle is controlled by a timer and the rotation of the pieces by an adjustable speed motor.

TSP series digital polishers combine the flexibility of individual/central pressure with the programming features of the digital panel. Once the grinding/polishing cycles have been set, the operator has just to select the cycle required for the type of sample to treat, and start it. The digital panel allows to set, for each cycle, the duration of grinding/polishing, the air pressure of the head, the frequency and duration of the fluid jets from the dispensers, the speed and direction of the working wheel rotation (clockwise or counterclockwise).
TSP grinder/polishers especially fit the requirements of laboratories where, in addition to high quality results, repetitiveness of tests according to standardized procedures is needed.

The drag finishing systems developed by Trowal represents a special technology for surface finishing of high value, delicate components, parts with many contours and complex geometry and extremely hard materials which are difficult to machine.
The applications for the Trowal drag finishing technology range from aggressive grinding to surface smoothing and high gloss polishing of decorative parts.
M-TMD 4/1
Functional principle
The components are attached to special fixtures and "dragged" in a planetary movement through a bed of grinding or polishing media.
- Compared to vibratory finishing, the process provides up to 40 times
higher grinding performance.
- The work pieces are individually attached onto fixtures and,
therefore, cannot impinge on each other.

PF32A - Mirror-like polishing with Sodick's EBM - electron beam machine.
At the point where even the most precise machining processes and tool concepts reach their limit is where the performance spectrum of the groundbreaking PF32A from Sodick steps in.
Because while others are still thinking in terms of µm, this new development makes it feasible to work in the sub-micron range. This is possible due to the fact that this new machine utilises a completely new technology for metal machining - the electron beam, with which surfaces that have been precisely machined can be polished to a mirrorlike sheen. Virtually at the touch of a button and within
Standard features of the PF32A:
First EBM in the world
Revolutionary polishing process
Mirror finishing within just a few minutes
Moving table for larger surfaces
|
|
Outline
Electron beam machining is the technology to use energy produced by forming argon gas stored in the vacuum chamber into plasma and to generate a "high power electron beam of a pulse shape in a large area" to melt the metal surface. The uneven surface is made flat by the repeated fusion and coagulation by heat and surface tension.
Effects
With EDMing, the residual gases left in the material are eliminated which results in a flat surface. Sodick EDM with the advanced SVC circuit(Finish circuit) ensures an even flat surface(before EBMing), resulting later in an ideal surface for Electron Beam machining. The EBM process provides excellent corrosion, friction, and water resistant surface, which is ideal for mold surfaces.

Sweco Finishing Mills utilize time-tested, three-dimensional Vibro-Energy® motion to perform processes such as de-burring, de-flashing, ball burnishing, radiusing, edge breaking, and pre-plate finishing. This motion subjects parts and media to a consistent high frequency tilting movement as they travel in a helical/orbital path around the chamber. The resulting compressive scrubbing action cleans and removes burrs, round sharp corners, and smooths out surface impressions. Since vertical/horizontal amplitudes and rate of vibration are completely adjustable, your finishing requirements can be handled quickly and efficiently. Another key feature of Sweco Finishing Mills is a polyurethane lining which has been degassed, hot poured, and hot cured.
Sweco Batch Finishing Mills are ideal for use with external separating systems, manual parts unloading and for processes that have no media and the entire load can be easily discharged out the bottom door.
Sweco Long Radius Finishing Mills provide a convenient means for separating parts from media. They provide both batch automatic and continuous finishing. Internal parts and media separation mills utilize a swing blade and a fixed separation screen mounted within the unit.
Sweco Spiral Finishing Mills make available a long-radius spiral finishing chamber featuring fully-automatic parts/media separation utilizing an air-operated discharge gate and a fixed separating screen. Even unusual shapes and sizes discharge easily. These units are suitable for a variety of finishing applications both batch and continuous. One of the most essential features on these mills is the long retention time of parts for single pass applications.
