BELT POLISHER

DRY & WET SURFACER

FOR DRY GRINDING:

Dry belt Surfacer is a continuous belt sander. It is used for removing sharp edges and for rough polishing of mounted/unmounted specimen. The Dry Belt Surfacer consists of a continuous belt of size 36″ X 4″ width (915 mm X 100 mm). The Belt runs on aluminium pulleys one of which is directly coupled to 1/4 H.P.,T.E.F.C. 220 Volts AC, single phase motor. The other pulley is fitted on a spindle in dolly which is spring loaded thus offering quick changing of worn out belts and keeping a fixed tension. The design also incorporates axial adjustment to align the belt in the centre. The belt runs over a plate situated between the two pulleys giving a working surface of approximately 4″ X 7″ area. It is totally enclosed for safety. The cover can be easily removed for changing the belt. Approximate dimensions of the base are 23″ X 20″ X 13″ height.

FOR DRY & WET SURFACE:

Similar to above but having arrangement for both wet and dry grinding it is supplied with coolant tank located in the base, a coolant pump with switch and pilot light, brush type coolant dispenser, water and drain connections. The switch enables dry polishing when put off. This is driven by a 1/4 H.P.,T.E.F.C. 220 Volts AC, single phase motor. The machine can use a large volume of water to keep the sample cool and avoid heat effects. A ‘S’ type water dispenser is used which remains parallel to the belt. The Machine is mounted on a self contained angle iron table.

ELECTROLYTIC POLISHER CUM ETCHER

Electrolytic Polishing is an electrochemical process for preparation of Metallogrpahic samples. It is a reverse process of electroplating, wherein the material from the samples is removed away by electrolytic action in presence of D.C. Potential. Electrolytic Polishing renders distortion free finely polished samples in seconds. In terms of quality, speed and ease of operations, electrolytic polishing exceeds mechanical polishing methods.

Necessary and optional Accessories
POWER SUPPLY UNIT. A 150 volts, 2.5 amps. DC supply source operating on 230 volts 50 cycles single phase AC mains. DC voltage varies with the help of a dimmerstat voltmeters with ranges 0-15 V and 0-150 V. Ammeters with ranges 0-250 MA and 0-2.5 A.DC.
