ZAI JSC has two main production workshop - workshop for tools with organic bond, producing high reinforced abrasive blades for cutting and grinding of metal and nonmetal materials and non-reinforced abrasive tools for grinding metal and nonmetal materials; and workshop for tools with inorganic bond producing ceramic and magnesium tools for grinding of metal and nonmetal materials.
Main production, with which in 1962 started work on the plant is the workshop for manufacture of abrasive tools of ceramic bond.
The technology of production in the workshop for tools with inorganic bond include the manufacture of abrasive mixtures, pressing, drying and firing in a tunnel furnace.
ZAI JSC has only one in Bulgaria 3000-ton press for automated production of large size grinding discs - up to 900 mm. Furthermore, it has workshop with 750, 500 and 250 ton presses automated, maintained in functional condition, meeting the highest requirements for accuracy of the product.
The second major production of ZAI JSC Berkovitsa is equipped with two unique in Bulgaria and high-tech machines of the latest generation for manufacture of tools with organic bond with parameters from 115 up to 125 mm and from 180 up to 230 mm. Each machine has a high capacity - up to 6000 disks at shift. The Full automation of the process includes a module for continuous quality control, allowing the minimization of the deviation of the parameters specified computer. Both machines are own investment by ZAI JSC for 1 million and 60 thousand Euro.
ZAI JSC Berkovitsa with the help of the European Regional Development Fund has invested in high-tech bakelite mashine for baking of tools with resin bond maintained the required temperature.
The majority of production of the workshop for manufacture of tools with organic bond is realized in the Eurozone and 20% meet the needs of the domestic market.
