High static rigidity,dynamic rigidity,and rotortion rigidity. Precise three jaw internal&external grinder for FX-150AAL Feed-on methodfront&rear automatic left&right automatic Spindle speedInternal 0-55000rpm external 0-12000rpm working head 0.75KW Motor Spindle 1HP*2 Machine dimension(L*W*H) 1000*800*1480 Net weight(approximate) 680kgs Processing rangeinternal diameter 1.5-160mm external diameter 0.5-400mm Machine Maintenance Chapter1.Principal Axis Section:Machine should be cleaned every-day accompanishing its job, Iron filings attached on the Principal Axis should be blew off using the air-gun,when blowing iron filings, must be perpendicular comapring with the Axis,which prevent iron filings blowing into inner Principal Axis,further shortening worklife of Principal Axis. ATTENTION! 2.Slide Rail Section:Inject located by the right side for the machine , must pull it for three or four times everyday,to enhance slide rail better lubricating ,Oil slide in the Inject's inner oil chamber should be added new oil slide after using exhausted , Afore adding new oil slide, keep vent valve 's back off opening up , that is for absolute cleaning inner storing fee-oil , then adding new oil slide ,for the specification is 'Mobi11405'. 3.Leather Belt Section:Wiping the leather-belt by cleaning cloth every two or three days , which prevent the belt pasting iron filings ,leading the influence for the Principal Axis' normal revolve,and worklife of the convey of wheel. 4.Electronic Control Section:Make sure the Electronic Control Box being closed in the working hours , preventing the dust coming in ,again installing the flushing device need to be high attentioned.for the coolant oil pouring into the Box inside. 5.Except point to the above-mentioned Cleaning and Maintenance , Adding anti-rust oil for all parts of Machine after ever-day cleaned, Done it thorough-going of dealing with matter for the anti-rust .which can extend worklife for the Machine.
