M1420 Conventional Universal Cylindrical Grinding Machine
Application:
* When conical grinding, the table can be swiveled 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 guarantee extraordinary results at any type of operation
* Strong reinforcements and solidly designed panels 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 the option of a programmable hold time at the end of each table movement
* Hydraulic or manual repositioning of grinding spindle stock
* Guideways in x- and y-axis are precisely constructed and hand-polished
* Longitudinal table guide and cross guide of grinding headstock each feature a V-guide and flat guide
