Description
Technical field
The present invention relates to panel processing technique field, especially, be related to a kind of curved face processing of ceramic product and finishing method and
Ceramic panel.
Background technology
Pottery tool has good wearability, and hardness is only second to diamond and reaches 9 grades of Mohs, and ceramic dense makes it have ratio simultaneously
The higher intensity of safety glass, the above-mentioned two characteristic of pottery is very suitable for for making high-end watch, mobile phone and other electronics
The accessories such as the shell of original paper.Simultaneously ceramic manufactures the manufacturing process more ring that process is than traditional plastic and glass etc.
Protect and energy-conservation, therefore ceramic material replaces traditional plastics, stainless steel material etc. as the shell of electronic product, will be that technology is sent out
The inexorable trend of exhibition.
For different products, ceramic panel structure has some difference, but primary structure is than relatively similar.As shown in Figure 1,
Several primary structures of ceramic panel are: cambered surface 01, bevelling 02, straight body position 03 and plane 04.Due to above-mentioned primary structure
Position, angle and size are all variant, from processing and fabricating to polishing process, each need using different processing methods.To fall
As a example the finishing method on side 02: in order to meet the requirement of high-end ceramic panel device development, obtain high light, the falling of low roughness
Side, must be polished to pottery, and this is the basic technology making ceramic panel reach ultra-smooth at present.
Because current ceramic product is just emerging for the technology making the accessories such as the shell of high-end watch, mobile phone and other electronic original parts
Rise, the technical staff of present patent application finds, do not have in prior art disclosed in be specific to the polishing side of ceramic product
, there is following weak point in method, and when being directly polished using the finishing method of presently disclosed ceramic product: 1, tool is no
Method is mated well with the bevelling of ceramic product, causes tool easily to wear and tear.2nd, the selection of polishing fluid and grinding force be not fine
Change, the ceramic product bevelling after polishing has that local surfaces are rough, it is insufficient to polish.3rd, once one can only be produced
Product are polished, and the working (machining) efficiency of product is low.
Content of the invention
Present invention aim at providing so that processing is more accurate, the bevelling roughness after polishing is lower, product polishing efficiency
The curved face processing of higher ceramic product and finishing method, to solve to process the technical problem not accurate, polishing is insufficient.
For achieving the above object, the invention provides a kind of curved face processing of ceramic product and finishing method, comprise the following steps:

A diameter of 20～100mm of sintering emery wheel；The angle ranging from single angle foretold between machine grip holder axis and sintering emery wheel axis；
C, sintering emery wheel rotation, control rotating speed at 3000～9000 rpms；The bevelling face of ceramic product is carried out polishing plus
Work, obtains the ceramic product with curved panel；
While polishing, pour into a mould coolant in the contact position of emery wheel and product；It is many that coolant comprises water, Polyethylene Glycol and many ethylene
Amine；
D, the ceramic product with curved panel is placed between grinding head for polishing and polishing mill lid, grinding head for polishing and ceramic product arc
Face coincide；
E, grinding head for polishing rotation, the relative rotation speed of grinding head for polishing is that between 1100～2000rpm, Stress control is in 0.1～0.5mpa
Between；
While polishing, contain sio in the contact position cast of bistrique and product2Polishing fluid, wherein sio2Mean particle dia is:
30～150nm.
Preferably, described grinding head posts mill skin, described mill skin is felt, epoxy resin skin or polished leather.
Preferably, ceramic product to be processed is wristwatch case or phone housing.
Preferably, described grinding head for polishing is the grinding head for polishing of four-head buffing machine.
Preferably, the feed speed of described sintering emery wheel is 0.1-0.2mm/min.
Present invention also provides the cambered surface of ceramic panel be using said method carry out curved face processing and polishing gained phone housing and
Wristwatch case.
The method have the advantages that
1st, processing precision is higher:
Ceramic product is placed in Dan Buji (also known as spherical surface miling-grinding machine) chuck the present invention, makes ceramic bevelling face at a certain angle
Be aligned sintering emery wheel horizontal plane carry out curved face processing after, then place it in polishing mill lid in be polished, can be according to reality
The size of product and radian, to adjust position and the gradient of chuck and grinding head for polishing, are mated well with the bevelling of ceramic product,
Tool is avoided to damage.
And, realize 360 degree of product bevelling evenly to polish, Yield lmproved 20～30%, obtain higher product quality.
2nd, polishing is more abundant:
The selection of polishing fluid and grinding force all more become more meticulous, and surface is more smooth.The area of the disposable qualification rate of product polishing
More than 90%, the surface roughness of ceramic product is less than 5nm.
3rd, production efficiency is higher:
Four-head buffing machine once can process the ceramic product in multiple grinding head for polishing, improve production efficiency simultaneously, greatly reduces life
Produce cost.
In addition to objects, features and advantages described above, the present invention also has other objects, features and advantages.Below
By reference picture, the present invention is further detailed explanation.
