  3. LAPI and POLI Tools

LAPI and POLI Tools

• The tools are made of polyurethane foam.
• The tools are cooled with water (no added abrasive necessary).
• The tools minimize cracking layer in worked glass thereby polishing is easier. 
• The tools are suitable for lathes (vertical way) as well as for flat machines (horizontal way).
• The tools are easily profiled.

Grinding – LAPI

• We produce 6 types of LAPI Tools. The difference is in the grit of incorporated abrasives. 
• Lapi Pink has the greatest material removal effect and creates the roughest surface on glass, whereas Lapi Blue has the smallest material removal effect and creates the finest surface on glass.

PINK • The tool is suitable for removing seams after moulding, for rough working within radii of various dimensions, etc.

 

VIOLET • The tool has the same use as Pink, however, it creates a finer surface with a slightly lower removal effect on glass than the Pink wheel.

 

ORANGE • The tool is suitable for various kinds of manual repairs prior and following chemical polishing as well as for fining before mechanical polishing.

 

GREEN • The tool is suitable for fine cutting after rough LAPI. The tool creates surfaces which can be polished mechanically.

 

BLACK • The tool can directly polish concave surfaces, wedge cuts, etc. It is well suited for manual repairs of sodium-potassium crystal.

 

BLUE • The tool achieves final surface quality comparable to surfaces after processing with the finest pumice. In many cases this tool can be used for the final polishing.

 

 

Polishing - POLI

• We offer 2 types of POLI Tools. The difference is in selected polishing powder.

Brown • The tool contains polishing powder (cerium oxide) in high concentration.

 

 

WHITE • The best polishing powder (Cerox 1650) is incorporated inside the tool.
