CYLINDRICAL GRINDER URS3000 N
Quantity: The URS 3000 N universal cylindrical grinding machine is suitable for external cylindrical grinding of workpieces up to 320 mm diameter. Part of the standard equipment is the internal grinding device, increasing the range of applications significantly. A popular model for machine construction, mould and tool making and production of small series.
When conical grinding, the table can be swivelled to either side and exactly positioned by using the scale
Oil film between bearing and spindle keeps vibrations at a minimum level, hence achieving outstanding results and top accuracy
Precisely balanced spindle head and solid grinding head guarantees extraordinary results at any type of operation
Strong reinforcements and solidly designed walls of the machine base makes it resistant to temperature fluctuations and deformations
Spindle is mounted from both sides and features adjustable sliding bearings consisting of three segments
Hydrodynamic bearing of spindle, therefore no contact between spindle and bearing
Longitudinal table feed can be set to automatic mode - hydraulically driven or manual mode - by handwheel
Stepless feed adjustments with selective programmable hold time at the end of each table movement
Longitudinal table guide and cross guide of grinding headstock each feature a V-guide and flat guide
Hydraulic or manual repositioning of grinding spindle stock
Guideways in x- and y-axis are precisely constructed and hand-polished-
