The basis for the production (modernization) was taken over the new VSZ-103.
Modernized hydraulics, new electrics (“RITTAL” housing, “ABB” components, “Schneider-electric” components), in accordance with ISO9002 standard, replacement of the electrical drive of the product with a frequency converter (Made in Japan, “Yaskawa”). The grinding wheel motor is equipped with a soft start system, a barograph is installed to indicate the load on the motors, and a barograph to control the oil temperature. The control circuit is constructed with an intelligent relay “Schneider-electric”. To control the grinding process in two axes, a ruler and DRO LIR-540R are installed.
Two inner sanding heads (Fortune), bezel. Depending on customer requirements, additional assets and lunettes can be produced
Machine location: Latvia
Year of construction 1999, 2018 completely overhauled by the manufacturer
The plant was used to manufacture and grind torpedoes, underwater mines and air bombs for military purposes.
Assembly and transport costs within the EU are included in the price.
