Universal cylindrical grinder URS 1000 N

The URS 1000 N universal cylindrical grinder is suitable for external cylindrical grinding operations on workpieces up to 320 mm in diameter; the standard internal grinding attachment further expands its application range. This machine is primarily used in mechanical machining, toolmaking, and forming, as well as for finishing small batches.

Property

• The oil film between the bearing and the spindle minimizes vibrations: this way it is possible to obtain precision and a good surface finish.
• The large table can be tilted for conical grinding to two different positions and set to the desired position by means of a scale
• Precisely aligned spindle head and stable grinding spindle head for best possible machining results in various grinding processes
• Thanks to the strong ribs and large walls, the machine base is relatively insensitive to temperature changes and deformation.
• Grinding spindle mounted on both sides with tri-segmented and subsequently adjustable surface sliding bearings
• The main spindle is hydrodynamically supported, meaning a film of oil prevents contact between the bearing and the spindle.
• The longitudinal movement of the table takes place manually by means of a handwheel or automatically by means of the hydraulic power supply.
• Continuously adjustable feed rate with optionally preselectable waiting time at the end of each movement phase
• The grinding spindle head is reset hydraulically or by handwheel
• Precision hardened and hand-scraped guides in the x and y axes
• Longitudinal table guide and cross guide of the grinding spindle head, each with a V-shaped and flat guide
