DRO Horizontal Boring Mills

Feature of DRO Boring and Milling Machine 1) The speed change of main motion and feed motion of the machine are all adopted hydraulic pre-selection centralized control, which can save the auxiliary time and increase the working efficiency of the machine. The indicator lamps are lighted up to give the signal during the course of speed and feed changing. 2) The vertical coordinate (headstock lifting direction) and cross coordinate (table transverse movement) and longitudinal coordinate ( table longitudinal movement, supplied according to the custom's requirement) are provided with new type Digital Display Unit with memory function, which make the machine with complete function and high accuracy. 3) The machine is to be used in following environment and operating conditions: Humidity: When under the max. temperature of 40°C, the relative humidity shall not be over the range of 50%, high relative humidity is allowed under low temperature (90% under 20° C). 4) Height above sea level: Lower than 2000 m. Atmosphere pollution: There is no excessive dust, acid gas, corrosive gas and salt component,i.e., dust concentration is not allowed more than 10mg/m3,and acid, salt and corrosive gas are not allowed containing. url:http://www.sfmachinetools.com
