CYLINDRICAL GRINDER URS800 N
Quantity: The URS 800 N universal cylindrical grinding machine features an excellent range of standard accessories which includes an inside grinding device and a 2-axis position display. Designed predominantly for model and tool making, this model is popular for the production of small serie
Hydro-dynamically mounted main spindle, oil film prevents contact between spindle and bearing
For conical grinding operations table can be tilted - scale allows precise adjustment to desired position
Guideways in x- and y-axis are precisely polished and manually finished
Longitudinal table guide and grinding spindle stock cross guide each feature V- and flat guiding
Achieve smooth results at various grinding operations due to the precisely adjusted spindle head and solid grinding spindle stock
Strong reinforcements and generously designed walls make the machine base resistant to temperature fluctuations and deformations
Oil film between spindle and bearing keeps the vibrations to a minimum to achieve top results and high accuracy
Longitudinal movement of table is either manual (by hand wheel) or automatic (by hydraulic feed)
Stepless feed adjustment with selective programmable stop at end of each table movement
Hydraulic or manual repositioning of grinding spindle stock
Grinding spindle features bearings on both sides and adjustable sliding flat grids
Swivelling spindle stock (up to 180°) for inside grinding operation-
