Surface Grinder – Reciprocating Table, Horizontal Spindle, Heavy

Surface Grinder – Reciprocating Table, Horizontal Spindle, Heavy

In our Reciprocating family we have separated all movements in X, Y and Z direction. Our objective is to attain a precision of 90°± 0° in all 3 axes and to preserve this precision through the life of the machine. This provides superior stability even at extreme ends of working range.

For large working area, high table loads and very high rates of material removal we offer our BW Series that distinguishes itself by its heavy-duty construction. The spindle head as well as vertical cross traverse and table guide-ways are specially designed for heavy- duty cycles.

The spindle runs in super precision angular contact preloaded bearings with optimum concentricity and balance characteristics. This sturdy design is key to accuracy, precision and reliability from the Alex Surface Grinder.

The spindle head travels in the vertical column in handscrapped guideways with power elevation and manual in-feed.
Automatic in-feed can also be provided as optional.

The transverse carriage carrying the column traverses firmly on the base on handscrapped guideways via an electromechanical drive. This provides intermittent cross-feed. The column carries out cross traverse only. This ensures the transverse guiding system is always uniformly supported by the rear base guide-ways regardless of column position. The spindle head only carries out vertical traverse, hence the grinding wheel is always at the same distance from vertical guide-ways regardless of working height, which in turn ensures absolute parallelism between grinding wheel and worktable.

The table carries out longitudinal traverse only, so that the entire grinding area is at all times fully supported by the guide-ways of the front base, even when the table is in its end positions.

The Alex low-pressure hydraulic unit is located inside the base, which establishes a defined thermal state in the machine frame.

All models are available with the option for CNC controls for automatic grinding cycle including wheel dressing and compensation.

All models can be customized for a specific application to suit specific customer needs.
