Universal cylindrical grinder URS 800 N

The URS 800 N universal circular grinder already meets every requirement in its standard version (internal grinding attachment, two 2-axis digital displays, etc.). This machine's design makes it ideal for tool and mold production, as well as for small series production.

Property

• The main spindle is hydrodynamically supported, meaning a film of oil prevents contact between the bearing and the spindle.
• The table can be tilted for conical grinding and set to the desired position using a scale
• 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
• Precisely aligned spindle head and stable grinding spindle head to achieve
• best possible machining results in various grinding processes
• Thanks to the strong ribs and large walls
• the base of the machine is relatively insensitive to temperature changes and deformation
• 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 longitudinal movement of the table takes place manually using a handwheel or automatically using 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
• Grinding spindle mounted on both sides with segmented and subsequently adjustable sliding grids
• The grinding spindle head is rotatable 180° for internal grinding
