Modernization:
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.

Completeness:
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

Former use:
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.
