How can the bearing seat be well machined?.

Answer:

Bearing seat hole in the traditional mechanical products, most of which are connected with the box as one, such as welding box and casting box, etc., but also inside the box needs and the box to put in the dry bearing holes.Now in a parallel reducer box for example (because I can't say with any illustrations of Baidu pictures) box size is about the transfer case body such as 300mm*200mm*200m, because of its location, cylindricity, parallel degree is not high technology recommendations on CNC vertical milling machine, radial drilling can even, length in 1M about the crane reducer basically 110 CNC boring machining center, or 110 can meet, some of the ship unloader or mill reducer reducer, length of about 3m-4m, the height of 2m above, this would require 160 or 180 CNC boring and boring.In some special case stem bearing hole because of reasons such as appearance still need this boring mobile I just heard, but also introduced some technical requirements of position accuracy is particularly high, we generally use 150 machining center Dirk, left side edge debugge three coordinate detection mode until the machine compensation adjustment to meet the requirements of the drawings in the processing of finished products.A tool fixture selection according to the specific conditions of parts, there is a process to do, some on both sides of the box bearing hole in need of a product does not allow a processing, some allowance for rough boring, then put in fine surface finishing bearing hole, etc. not to enumerate.
The small bearing seat is machined on the lathe disc and bending plate.The large bearing seat is machined on the boring machine.
I. processing methods:1., small bearing seat in the lathe disc, bending plate processing. 2. bearing seat processing in boring machine.Two, the bearing seat bore a brief introduction:The installation point for bearing to provide the running base and the precise matching with the bearing is the bearing seat hole. The biggest influence factor of the running accuracy and the length of the bearing is the matching precision of the bearing bore. Bearing seat hole to achieve the precise size of the bearing requirements, and to batch size are unified, it is difficult to achieve in the mechanical processing, the use of new processing technology, processing is the urgent need for bearing users.
