1 CIRCULAR VIBRATORS MACHINES FOR SURFACE FINISHING WITH MANUAL OR EXTERNAL AUTOMATIC SEPARATION AUTOMATIC MODULAR WORK STATION WHEN PERFECTION STARTS WITH THE FINISH

2 SM and SP series vibrators with manual or external automatic separation for every need, just right for the perfect finish Construction features 1 Through meticolous attention to design and engineering, and through the employment of cutting-edge testing equipment, we have achieved customised three-dimensional balancing of our equipment. This has virtually eliminated harmonics, which was previously a frequent cause of problems. 2 The strong, compact structure of our vibratory equipment is fabricated in quality certified steel using an advanced electro welding process. For greater reliability, the structure is normalised through heat treatment followed by sandblasting and painting, performed using the best possible protection and the most up-to-date anti-pollution techniques. 3 The monolithic tank, without a sump or screws, is lined with a thick layer of scratch-proof, oil-proof and anti-stick polyurethane. Lower outlet to enable rapid replacement of inserts, with block-proof polyurethane plug. Ball valve for water drain; connection for second drain with manual or automatic valve. Manifold with capillary holes for washing and rinsing finished product. 4 The flat groove is the primary condition for obtaining an optimum finish and an improved production output. The new SM and SP series of vibratory machines delivers the highest standard of technology to the ever growing demands of the surface finishing industry. In order to control costs as well as maintain high quality standards in their finishing departments, an increasing number of companies have adopted vibratory finishing to fulfill their specialised requirements. The SM and SP series of vibrators are the result of the most technologically advanced machining and construction techniques. They allow modular automatic work stations to be created, enabling the most complex process cycles to be completed in the most rational manner (see the station on the cover). 5 Separation of parts from media is accomplished automatically, using either magnetic extractors (see accessories on page 10) or a pneumatic unloader or by component surfacing. 6 Moto-Vibrator : The "heart" of the machine is well oversized and requires no scheduled maintenance or regular greasing. 7 Vibration control, thanks to the most versatile and universal system allows the choice of either manual or automatic operation for rapid and perfect results. 8 Three-dimensional balancing and adjustment of the machine delivers continuous and correct adherence of the abrasive inserts to the pieces being processed, preventing harsh movements which cause pitting and hardening of the surfaces. The result is an optimum fine smoothing, micro-finishing and polishing process. 2

3 Ideal and functional proportions in the flat groove structure Universal control of the centrifugal forces Main Uses These machines have been designed for surface finishing of especially delicate metal parts where automatic wave extraction cannot at times be used because of flecking. They are also designed for large items that require high quality such as faucets, handles, household articles, etc., and special processes such as: Steel (gears, trinkets, tools, etc.) Stainless steel (houseware, cutlery, bearing parts, food industry components) Aluminium (pressed or die-cast) Alpaca (pump bodies, cycle components, electronic parts, spectacles, etc.) Brass (taps, handles, metal trinkets, etc.) Zamak (casting, die casting) The machines are used in particular for deburring, smoothing, polishing and matte finishing of pieces, with maximum dimensions and weights as reported in the table of page 11, using ureic, plastic, ceramic, wooden chips and corn sawdust. Production Depends on the application, type of material, dimensions and shape of the pieces. Refer to our research service. Wall column mounted electric panels - wall-mounted waterproof control panel IP V a.c. controls to EC standards - solutions available: a) manual unloading b) automatic unloading c) automatic unloading with inverter Working cycle In accordance with the application, material, dimensions, weight and shape of the pieces. Our research and applications service will indicate the theoretical/practical methods for determining the working cycle, abrasive inserts and auxiliary compounds to use. 3

4 Distinguishing features of a continuous evolution: the strong points of Nicem vibrators Standard electric control panel for dryer ASC Dimensions: 400 x 500 x 200 mm Standard automatic electric control with timed inversion for VIB SM and SP Dimensions: 400 x 500 x 200 mm A very versatile machine with regard to options and choice of operating modes, adaptable to any type of working with high quality finish: - this machine does not transmit any vibration to the base, and therefore to the ground; whatsoever does not need any floor anchors, thanks to its special design. - Monolithic tank (without sump or screws) with thick, scratch-proof, oil-proof polyurethane lining with anti-stick grooves. - New abrasive insert/water (main) drain plug with special anti-blocking system. - Water drain hole positioned lower than the groove; suitable for ball valve (manual) or pneumatic servo-controlled automatic valve. - Easy to clean water drain plug/filter. - The SM and SP vibrator series are completely flat and as such have the greatest capacity of the circular VIB family, having the highest output/productivity ratio. The flat groove does not have any obstacles along its route and consequently guarantees the best quality finish. - They are manual machines but can be automated completely (see cover photo) with magnetic extractors, with the application of the pneumatic unloader and the help of transport belts and vibrating screens, as well as a battery of vibrators, vibrating dryers, or a machine with a tunnel, Archimedian screw, or mat to wash or dry. There is therefore no need for the presence of an operator during the processing, separation, and unloading phases. - The machines can be programmed from an automatic control panel. Used together with the ASC dryer, means that the process can be completed without the presence of any personnel. - Quick and simple maintenance. - Lubrication: Long Life.

12 SOUNDPROOFING COVERS Soundproofing covers are available for the five vibrator models and three dryer models. The covers have manual/automatic opening and closing, thanks to which the noise levels are contained. For overall dimensions, refer to the table on page 11. Waste water treatment Purification plants with continuous and discontinuous sludge recovery. Nicem can supply purification plants from the simplest manual type to the most automatic for the clarification of water from vibrofinishing treatment. In manual plants, filtering is obtained by decantation and separation through filtering bags of the solid elements which can be founded in waste water. In semi-automatic plants, the clarification of the water is obtained byaddingade-emulsifying-adsorbent product that causes the formation of flocculi which adsorb the major part of impurities in the water. The purifying process is based on the clarification of the water via flocculation and decantation process. All the treatments produce waste sludge which is of the palpable and stabilised type and must be disposed of as "special waste". In the first solution (DEC2N) the cycle is manual and discontinuous with control panel with motor protection device.
