Numerical control cylindrical grinder machines citing of typical spare parts

5 ㎜) , everywhere unilateral grinding surplus 0.

1 ㎜, try an analysis grinding of its numerical control machines craft. Graph 12 nozzle a powerful person 1. Grinding workpiece part drawing analyses 10h5 of Φ of the circle outside this spare parts () ㎜ and Ra0 of cone surface roughness.

2 μ M, and coaxial spends Φ 0.

005 ㎜ are the focal point that grinding treatment should reach. 2. Choice device basis is mixed by the appearance of treatment spare parts the condition such as material, choose cylindrical grinder of GA5N numerical control. Numerical control system is FANUC-10T, deserve to have automatic measurement unit. 3. Workpiece technology program decides the requirement that spends because of having coaxial really, want to install the grinding that places the circle outside finishing and cone so. According to the structural appearance of nozzle a powerful person, use M12 × 0.

16 ㎜ of 5 ㎜ whorl and Φ flank screws fixed position. Grinding method can wear a columnar face with control of smooth emery wheel already, reoccupy circular arc, linear interpolation walks out of circular arc face and cone (see a picture 13) , also can become emery wheel nap figure of outline of standard of nozzle a powerful person, undertake figuration grinding (see a picture 14) . Graph 13 use interpolation function grinding to pursue two kinds of plan compare 14 figuration grinding, grind circular arc and cone with smooth emery wheel, have most advanced grinding only, interface is small, emery wheel wears away fast, cone precision is low, surface roughness is poor, because this is unfavorable,adopt this plan. Because want the length of grinding part not quite, can use the means of figuration grinding, departmental cent grinding efficiency is tall at the same time and dimension precision is more consistent, the surface roughness value of cone part also is met small. But as a result of the constant change of emery wheel dimension as grinding process, bigger accumulation arises in batch treatment error, the dimension public errand of unwarrantable spare parts. Undoubted, use measure grinding to be able to solve afore-mentioned problems directly. This machine tool provided automatic measurement unit, achieve a measuring instrument when dimension of part be metricaled by grinding workpiece when some set is worth, the measuring instrument issues signal, the takes G31 block that carrying out ends, hop to unload one block. Accordingly, a greater relative value can give in block, in this block motion dictates to set value is reached before was not being carried out, this paragraphs of the rest moves by oversight, enter carry out below one block. Use this kind of method to be able to make the public errand between each spare parts is controlled in ± 0.

In 001 ㎜. 4. External diameter of parameter of craft of treatment of numerical control grinding is transverse the set of grinding condition: Measure partial 1P=0 directly.
