Description
[technical field]
The invention belongs to the electrovacuum technology field and specially refer to the turning process that a kind of electrovacuum is used glass.
[background technology]
A kind of unformed shape by the melting object obtains through cooling is called vitreous state, and it is a kind of state of material outwardness, is similar to gaseous state, liquid state, crystallization etc.Glass belongs to the material of this class " vitreous state " exactly, and it is that various oxide compound heating and meltings become melt, obtains through overcooling again.
The development of electron tube once generally adopted glass as insulating material in the pipe shell-and-tube in early days, and at present, the electrovacuum ceramics that performance is more good has replaced glass in a large number, particularly is used widely in the microwave tube at electron tube.But because glass has the advantage of himself, it is at electron tube, especially still have a wide range of applications in display device, the photoelectric device etc., even in microwave tube, glass is a small amount of output window that is used as some pipe still also, the resonant window of discharge tube etc.
In the course of processing of traditional electron tube with the glass component, all be to adopt diamond cutter to cut and grinding.Along with the development of technology, the function of glass component is more and more, and shape becomes increasingly complex, and needs the amount of processing also more and more.High with the diamond cutter cost, working (machining) efficiency is also low.
[summary of the invention]
Technical problem to be solved by this invention is to propose a kind of electrovacuum of actually operating that can instruct with the turning process of glass, to improve traditional glass working method cost height, inefficient shortcoming.

[embodiment]
1, the electrovacuum annealing process of glass material:
In traditional glass processing, bursting that inside glass stress causes is the not high one of the main reasons of passing rate of processing.Glass all can cause stress in heating, cooling and the course of processing.In order to eliminate this stress, must carry out anneal.So-called annealing reheats glasswork to conversion temp exactly, insulation for some time, and then Slow cooling is to normal temperature.The conversion temp of glass refers to the minimum temperature that the glass solid-state properties disappears, and being commonly defined as viscosity is 10
13Pool (1 pool=1 dyne. second/centimetre
2) temperature be conversion temp.This temperature can be found in the material behavior of producer, and each producer is not quite similar.
The annealing standard of the glass of the present invention regulation is, glass heats is high about 5 ℃ to the conversion temp that provides than producer, and then insulation 30min cools to room temperature with the furnace, do not allow to adopt the form such as forced air cooling to improve its rate of cooling in process of cooling.
The selection of lathe tool material when 2, electrovacuum is with glass turning processing:
Select to add the rare metal carbon compound as: YW1, YW2 are as cutter material.
