fasteners & spring production

Spring specialists at OMD With more than 50 years’ experience as a manufacturer of spring end grinding machines, OMD Officina Meccanica Domaso is also specialised in the production of wet grinding machines for hot coiled springs and for grinding spring ends with a wire diameter up to 90mm. Series H (models: H50, H80, H100, H150), which are traditional pendulum grinding machines with one grinding wheel for grinding one spring end at a time. For big production volumes, Series HA/2 (models: HA80/2; HA100/2) machines have two grinding wheels and horizontal axis, with automatic progressive cycle for simultaneously grinding of both spring ends. These machines are designed for working in aggressive environments and are complete with technically reliable solutions, accuracy and selected materials. The pendulum grinding machines have a horizontal spindle for grinding on the front surface of the grinding wheel with automatic feed and automatic compensation of the grinding wheel. The production range includes two series:

The machines offer following working methods:

• • •

Spindle group feed with constant grinding pressure; Spindle group feed with variable pressure; Grinding with cooling breaks.

The Series H150 traditional pendulum grinding machine ▲

The series HA/2 consists of a double, horizontal mandrel and a loading plate for the simultaneous grinding of both spring ends. The machines are equipped with automatic control and positioning system, automatic grinding wheel compensation, automatic dressing for grinding wheels, electronic adjustment of the loading plate rotation and system for recycling cooling water.

The working methods of these machines are: Automatic grinding system with variable feed; Automatic grinding system with constant pressure; Automatic grinding system with constant feed; Automatic grinding system with cooling breaks. • • • •

The machines are PLC controlled and use a simple and functional operator interface for programming and diagnostics. Finally, the possibility to use an inverter enables programming the rotation speed of the grinding wheel according to the used abrasive material and/or the processed material.
