G. Indars, consultant, has 35 years of experience in grinding, lapping and 
polishing as well as extensive knowledge of diamond and other abrasive 
compound formulations. Process development and technology transfer are also 
offered.

Gunars Indars consults on a wide range of material processing requirements including tight tolerances, extremely flat surfaces, optical finishes, very thin parts and also choosing the right diamond or abrasive to lap or polish materials like molybdenum or even internal polishing of a small diameter bent titanium tube. Process capabilities include lapping and polishing, machining and shaping, diamond sawing, dicing, wafering, cutting and slicing, micro drilling, precision honing, ceramic machining, quartz and glass machining, optical polishing, flat lapping, silicon polishing, diamond and other abrasive compound formulating, ceramic annealing and joining, anodic bonding, laser slag removal, wafer and substrate thinning, semiconductor material backlapping, diamond wheel dressing, chip reduction in dicing, precise metrology measurements, edge grinding and crystal wafering.
