Embodiment one
Fig. 1 is the structural schematic diagram of the composite ceramics turning blank 100 in the embodiment of the present invention one；Fig. 2 is Fig. 1 along B-B
The cross-sectional view of line；Fig. 3 is enlarged view at the A of Fig. 1.Fig. 1, Fig. 2, Fig. 3 are please referred to, the composite ceramics turning base in the present embodiment
Part 100 includes ceramic form 10 and filled layer 20.Filled layer 20 includes being bonded in the work surface P1 of ceramic form 10 and filling out
Fill the first filling part 21 of the pit C1 on work surface P1.
In process, process tool by ceramic form 10 apply perpendicular to pit C1 depth direction horizontal force.
Inventor the study found that the reason of existing Machining of Ceramics method generallys use grinding first is that ceramic batch to be processed
Surface be the out-of-flatness with many pit C1 surface, this makes ceramic form 10 in the horizontal force by cutter, and not
The resistivity being capable of providing with depth layer is different, is mainly reflected in have the surface layer of pit C1 due to the presence of pit C1, and
The feature that certain cantilever design is presented loses lateral support ability at pit C1, thus surface layer cutter active force and lateral
Resultant force between support force is not zero, and is greater than the resultant force of lower layer, so that ceramic surface by one is acted on ceramics on the whole
10 surface layer of blank, and using the hole bottom of pit C1 as the torque of position, which makes, under the action of the horizontal force of cutter,
It is easy to crack ceramic form 10 along the tangential direction of the lower end pit C1, it is serious to occur collapsing to what depth direction extended
Fragment obtains smooth finished surface to can not process by the method for turning of big cutting data, limits the processing of ceramics
Efficiency.
In the present embodiment by ceramic form 10 work surface P1 fill filled layer 20, the first of filled layer 20
Filling part 21 fills the pit C1 on work surface P1, and when using the turnery processing of larger cutting data, turning cutting tool is applied
The horizontal force for being added on 10 surface of ceramic form is supported jointly by the laterally supporting power of ceramic form 10 and the first filling part 21, pit
Ceramic form 10 at C1 can equally receive good lateral support, and 10 cutting lay of ceramic form is everywhere by of substantially equal
Load, therefore resultant force is substantially zeroed and is parallel to the work surface P1 of ceramic form 10, ceramic form 10 is not easy to occur deep
It spends the crackle in direction or fragmentation phenomenon occurs, so as to obtain smooth finished surface under larger cutting data.This reality as a result,
Applying the composite ceramics turning blank 100 in example can allow for the machining of larger cutting data, have high in machining efficiency and energy
Enough obtain the beneficial effect of smooth finished surface.
For the circumferential surface for further protecting ceramic form 10, filled layer 20 further includes the second of the circumferential surface of encirclement ceramic form 10
Filling part 22.The setting of second filling part 22, can so that when needing to carry out round corner machining to the seamed edge of ceramic form 10
Guarantee seamed edge uniform force in process, is less prone to fragmentation phenomenon.And the outer peripheral surface and ceramic blank of the second filling part 22
Can also have clamping part 22a between the circumferential surface of part 10, to facilitate the clamping of the ceramic form 10 of plate-like structure before processing, keep away
Exempt from the processing for directly clamping the influence ceramic form 10 of ceramic form 10.
Heat molten type material of the filled layer 20 above-mentioned by fusing point lower than ceramic form 10 is constituted, such as filled layer 20 is by high score
Sub- polymer or fusing point are constituted lower than the metal or alloy of ceramic form 10, as aluminium and its alloy or titanium and its alloy are constituted.
