Sewing machine for the first time assembly or overhaul is assembled after, the the impact of the the performance of the device, is huge. Poor assembly quality sewing machine, low accuracy, poor performance, sound, torque, short life; On the contrary, some high precision parts, carefully select the assembly and precise adjustments can still assemble performance than good equipment.
The assembly process, some link easily overlooked, caused by a obvious impact on tend to be the assembly quality, need to be pay attention to.
1, to protect the parts clean
By careful cleaning and washing, ensure that the sewing machine parts cleaning, to ensure the quality of the assembly and extend the life of the basis of the sewing machine. Special sleeve, SKF bearings, pumps, and contains rotating and swinging mating parts parts should be carefully cleaned.
If the when the a variety of SKF bearings class parts is assembly are, ranging from caused by shaft sleeve warming is too high and of drive torque of is too heavy, is serious when can due to debris accelerate the wear and tear, appear the "occlusal" and and other serious fault unclean could encounter difficulties with.
2, according to the procedure operation
Where a, After the the surface-treated of the surface of the baking finish, electroplating and other the sewing machine Parts, All the of its assembly joining surface (, including Hole, the groove, Flat-screen and an Screw Hole) and, etc. on,, has a adhesive layer, therefore in the the prior to assembly, will be subjected to an Order by craft on a bought of such Parts the The technical requirements, the first conduct finishing, and then you can to enter the the assembly state.
If you assembly to to does not meet the the the the technical requirements stipulated, the sewing machine on the can not be work properly. Parts and components between the, the the the the mutual position of in the between the-agency is is not correct, also affects the the the work of performance of the sewing machine.
