RAMAN Hydraulic Surface Grinding Machine
Developement
Surface Grinding are backed by two decades of intensive research and development. Engineered with utmost precision. RAMAN Surface Grinders are built with highest accuracy for a long and trouble free services under the most stringent shop floor requirement. Your shops will turn out better work, more profitable with any one of these. Raman Surface Machines for years to come. Raman Surface Grinding Machines Conform to the international Standards of accuracy, as prescribed by Dr. Schlizengear , and this accuracy endures over the years.
Special Features
RAMAN Surface Machine has a unique bed-type design in which the bed carrying the table and the upright are aligned exactly at right angles. The saddle is guided on hardened and ground V-guide ways resting on high precision steel balls for smooth operations.
Wheel Head is mounted on rigidity constructed vertical column supported by pre-loaded precision bearing. Spindle is driven by means of a set of V-belts. All driving pulleys are dynamically balanced . Vertical feed is actuated through a mechanical gear drive incorporated inside the column.
Hydraulic Longitudinal traverse is infinitely variable ranging from 1.5 to 18 metersper minute.Fine feed capability 0.001 mm. Longitudinal table Transvere is
Lubrication
Automatic lubrication system is built-in feature of each RAMAN Surface Grinding Machine. The Table, Saddle and Cross Feed Screwhave an arrangement for continuous lubrication. Lubricant is fed into required areas under constant pressure. Over spilling lubricant is drained into the reservoir.
