Description
Technical field
The invention belongs to ceramic processing technique field, in particular, provide a kind of pressureless sintering carborundum thin-walled workpiece and add
Work method.
Background technology
The Mohs' hardness of silicon carbide ceramics reaches 9.2-9.5 grades, is only second to diamond, very difficult processing.Pressureless sintering carbon
During SiClx ceramics thin-wall part processing, in order to avoid product is crushed in process, the depth of cut is very small, only 0.005mm,
Processing efficiency is especially low.The present invention increases workpiece by the way of space between paraffin filling inner hole of workpiece and workpiece and frock and added
The larger depth of cut can be set in the intensity in man-hour, process, processing efficiency is effectively improved.
The content of the invention
It is an object of the invention to provide a kind of pressureless sintering carborundum thin-walled workpiece processing method, existing production is solved
The problem of product processing efficiency is low, improves the processing efficiency of product.
Workpiece is fixed using processing tool and paraffin by the present invention, is increased Workpiece structure intensity, is passed through surface grinding machine
And machining center is processed to it, Product processing efficiency is improved.Concrete technology step is as follows：
Product blank shape size 141*141*32mm, hole size 135*135*32mm, wall thickness 3mm.Product design chi
Very little 140*140*30mm, hole size 136*136*30mm, wall thickness 2mm；Characterized in that, processing step and the technology of control ginseng
Number is as follows：
(1) two planes above and below workpiece are processed using surface grinding machine：
1) using paraffin filling inner hole of workpiece is made by oneself, filling self-control paraffin is common paraffin and rosin in mass ratio 3:1-
6:1 is formulated；
2) workpiece for making wax by oneself is fixed on the workbench of flat stone mill by fixture, be ground respectively using surface grinding machine
Lower two planes；
(2) side of outside four of workpiece is processed using machining center：
It is fixed on by fixture by the workpiece for making paraffin by oneself is filled on the workbench of machining center, utilizes Φ 20- Φ 40mm
Resin-bonded diamond grinding head is processed to four sides of outer workpiece；
(3) side of inside four of workpiece is processed using machining center：
1) heating removes inner hole of workpiece self-control paraffin, workpiece is put in the middle of metal frock, metal frock hole size ratio
The big 30mm of outer workpiece size, highly more than workpiece height 5-10mm, thickness 15-20mm, using make by oneself paraffin filling frock with
Space in the middle of workpiece, wherein frock one end and workpiece one end are in the same plane；
2) above-mentioned frock and workpiece are fixed on the workbench of machining center, utilize Φ 12- Φ 16mm resin-bondeds gold
Hard rock bistrique is processed to four sides of inside workpiece；
3) after machining, heated partses remove self-control paraffin, and use alcohol washes, obtain product.
The diamond grit of described diamond grinding head is 80-180 mesh.
It is an advantage of the current invention that workpiece is fixed using processing tool and self-control paraffin, increase Workpiece structure is strong
Degree, is processed by surface grinding machine and machining center to it, improves Product processing efficiency.
