Why casting defects and parts damage can cause oil leakage in CNC machining centers
The oil leakage in the CNC machining center is generally divided into three states,namely leakage,dripping and oil flow.Under normal circumstances,every hour and a half of the static bonding surface,a drop of oil and a moving joint surface every 6 minutes drop a drop of oil is leaking.Whether it is a moving joint or a static joint,when a drop of oil is dropped every 2-3 minutes,it is dripping oil;more than 5 drops per minute is flowing oil.
The general requirement for the equipment to reach the leak is that there must be no leakage at the external static joint surface of the equipment,and slight leakage is allowed at the joint surface,but it is not allowed to flow to the ground.Some leakage inside the device is allowed,but it is not allowed to penetrate into the electrical box and the drive belt,and can be led back into the lubrication box.Why do casting defects and parts damage cause oil leakage in CNC machining centers?
(1)The castings have defects such as blisters,pores,cracks,loose tissue,etc.,and no measures are taken.During the use of the equipment,these defects are often the source of oil leakage.
(2)When the oil pipe and pipe joint are made of plastic or oil-resistant rubber products,the materials will age and become hard and brittle,causing oil leakage due to rupture of the oil pipe and pipe joints.
(3)After long-term use of the sealing ring,especially those in the moving parts,the sealing performance will be lost due to friction and wear.In addition,if the gap between the shaft and the shaft hole(sleeve)increases,the oil leakage is also caused.
(4)Parts processing accuracy error and other reasons.For example,the flatness of the joint surface of the box body and the lid of the box is too poor,the surface roughness is too large,and the residual stress of the workpiece is too large to cause deformation of the workpiece,so that the joint surface is not tightly attached.Or if the fasteners are loose,etc.,it will cause oil leakage.
When the CNC machining center is seriously leaking,it will affect the work of our CNC lathe.When there is a problem with our CNC lathe,we must deal with it in time.
