Universal cylindrical grinder URS 800 N

The universal circular grinder URS 800 N meets every requirement already in the standard version (internal grinding device, 2 2-axis digital displays, etc.). This machine, based on the way it was designed, is ideal for the production of tools and moulds, but also for small series production.

Properties

• The main spindle is hydrodynamically supported, meaning that 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 transverse guide of the grinding spindle head, each with a V-shaped and flat guide
• Precision 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 reduces vibrations to a minimum: in this way it is possible to obtain precision and a good surface finish
• The longitudinal movement of the table takes place manually via handwheel or automatically via hydraulic power
• Continuously adjustable advancement with possibly pre-selectable waiting time at the end of each movement phase
• The resetting of the grinding spindle head occurs hydraulically or using a handwheel
• Grinding spindle mounted on both sides with segmented and subsequently adjustable sliding grids
• The grinding spindle head can be rotated 180° for internal grinding
