Precision Profile Grinders

Precision Surface & Profile Grinders

Description

• In our NH 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 at all times. This provides superior stability even at extreme ends of working range.
• The spindle runs in super precision angular contact preloaded bearings with optimum concentricity and balance characteristics.
• The spindle head travels in the vertical column in handscrapped guideways with power elevation and manual infeed
• The transverse carriage carrying the column traverses firmly on the base on handscrapped guideways via electromechanical drive. This provides intermittent cross infeed.
• The table carries out longitudinal traverse only, so that the entire grinding area is at all times fully supported by the slide ways of the front base, even when the table is in its end position.
• The column carries out cross traverse only. This ensures the transverse guiding system is always uniformly supported by the rear base slideways regardless of column position. the spindle head only carries out vertical traverse, hence the grinding wheel is always at the same distance from vertical guideways regardless of working height, which in turn ensures absolute parallelism between grinding wheel and worktable.
• 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 guideways are specially designed for heavy duty cycles.
• The Alex low pressure hydraulic unit is located inside the base which establishes a defined thermal state in the machine frame.
• Optional: All models are available with CNC controls for automatic grinding cycle including wheel dressing and compensation.
• All models can be customized for specific application to suit customer needs.
• For Creep feed applications we offer our CF Series. This series focus is on individual production solutions. All 3axes X,Y,Z are powered by servomotors and drives through precision ball screws. feed rates start from a few millimeters to a very wide range on the upper end.
• Spindle is of superior rigid construction to handle heavy full cur grinding load.
• Coolant system is of very robust design to ensure adequate dissipation of heat.
• Dressing system is designed to suit individual application. (Fully automatic cycle to include rapid approach creep feed grinding, auto dressing, compensation and return to home position)
