Lap Sanders

 

If you want to polish flat surfaces, like book ends and geodes, then you use a vibra-lap. If you want polished nuggets of tumbled stones, then you use a tumbler, if you want to cut and shape rocks for jewelry or polish an end of petrified wood, then you use a cabochon unit. There are other more advanced methods of polishing, like making spheres, marbles, faceting gemstones, and carving.

Here is the differences explained:

Vibra-lapping: To polish a flat surface, like a book end or geode, you use a saw to cut your flat surface, then a grinder to remove any burrs left by the saw, then a vibra-lap to polish.

A vibra-lap is a round pan that vibrates. You place grit and water in the flat pan and then place your rock in on the grit. It vibrates and grinds down the surface. When vibralapping, you complete the process in 3 stages--coarse, fine, and polish. Each stage takes 6-8 hours. You fill the pan 2/3rds full of rock, so if you are polishing geodes, usually you can do 3-4 sets at a time.

GRIT SEQUENCE FOR LAPPING

The following sequence of silicon carbide grits is commonly used, and will generally produce a satisfactory polish on most materials:  60/90, 220, 400, 600, 1000, and then a polish.  Generally, the more steps the better the polish.

Automatic Vibrating Lapidary Unit

Takes all the work out of lapping. Just load, start & walk away

 

The vibrating lap is designed to abrade and polish automatically. The inertia of the heavy rock slab holds it relatively still while the lap pan vibrates underneath. This action replaces the circular rotation used by conventional lapping machines.

Our new design and grooved plate gives you faster cutting. Bumper ring prevents gemstone damage. Pad insert enables work piece to be polished in the same pan. One thumb screw releases pan for easy cleaning.

Comes complete with 110V, 60 HZ motor, polish pad, bumper ring, instructions and guarantee. 

When ordering specify 'Model Number' and item ordering.

Vibratory Lap Model DL-18

 

Double Deck Vibratory Lap Model DL-18
You can be rough grinding and finish polishing at the same time with this 18" double pan set-up
.

Use the top pan with its special pad for all polishing and the lower pan for the other stages of grind and pre-polish. Brackets hold the two pans in place, one above the other, and are designed for easy removal of the pans. Slabs rotate in a circular orbit so there is little damage to any stone edge. Use a Lapmate (described below) and you greatly reduce your lapping time. Machine is made of non-rusting aluminum castings.
 Only weighs 50 pounds so can be moved from place to place but is still heavy enough for stability while in operation.

The machine comes with frame, motor, two pans, polishing pad, set of brackets.

Diamond Pacific
"Vi-Bro-Laps" 

Both the 20" & 27" Vi-Bro-Lap models give you the satisfaction of achieving flat surfaces on geode halves, agate, petrified wood & other material, yet relieves you of the necessity for constant attention to the lapping process. --Diamond Pacific        Call for shipping information on this item.

 Also comes with Lap Mate weight for slabs!

Features:

  • Can accommodate a number of specimens at the same time

  • Tempered aluminum lap plate is grooved in a criss-cross pattern, permitting abrasive particles to circulate between the lap plate and the work piece so that the abrasive itself is continuously being crushed into a smaller size--this reduces the number of different grit sizes which are needed

  • Turn over the lap plate to the polishing pad side which is cemented on. Combined with polishing compound, a fine mirror-like finish is produced easily

  • Lap plates are manufactured from heat-treated aluminum alloy to produce a tough, wear-resistant surface. Each surface has milled V-grooves in a square grid pattern.

  • Suspension is controlled by aircraft strength cable, adjustable for fine leveling to keep work pieces evenly distributed over the lap plate surface.

  • 20VL measures 21"W x 21"D x2 1"H

  • 27Vl measures 28"W x 28"D x 30"H

  • Frame is welded, fabricated steel for stability

  • Comes with 1/3 HP motor, one medium Lapmate, polish pad & galvanized circle. 

* Crating fee included

When ordering specify 'Vi-Bro Lap and item ordering' as well as size.
