Description
Technical field
The present invention relates to a kind of method for grinding and isolated plant thereof, especially a kind of method for grinding and isolated plant thereof that square or regular polygon is polished into spheroid or accurate spheroid.
Background technology
In the prior art, the production process of spherosome generally includes following steps: 1) plate material is cut into square; 2) rolling grinding: utilize the mutual shear action of abrasive media and square,, make it to become the torispherical polyhedron of corner slyness with the corner angle and the Edge Blend of square; 3) use the electroplated diamond abrasive sheet of different-grain diameter successively, the polyhedron rough lapping is become accurate spheroid; 4) with abrasive media accurate ball lapping is become spheroid; 5) use the fine gtinding medium at last, spherome surface is handled, so that spheroid reaches high-precision product requirement.
Above-mentioned rolling method for grinding is suitable for the bigger material of volume, but often makes a futile effort for the less regular polygon of volume.Tracing it to its cause, mainly is that the weight of little regular polygon is too light, and the friction between little regular polygon and the abrasive media can't produce effective grinding.Even it is also of no avail to add heavy iron and lead sweat in abrasive media, it is cracked that little regular polygon is produced.
Summary of the invention
The technical problem to be solved in the present invention is exactly for solving the deficiencies in the prior art, a kind of suspension grinding method of the innovation that is used to make spheroid or accurate spheroid is provided and is applicable to the suspension grinding device of the uniqueness of this technology, using this method both can polish slick and sly by quickly and efficiently that weight is lighter little regular polygon grinding charge, can be provided effective ground effect by abrasive body to what make again, and can not damage by abrasive body by more crisp frangible material.
Technical solution of the present invention is as follows:
Suspension grinding method mainly comprises the following steps:
1. get the raw materials ready, be about to grinding charge and cut into accurate regular polygon or the supplied materials of accurate regular polygon is ready to;
2. in a container, pack into and have the liquid of proper viscosity;
3. the liquid of will this accurate regular polygon grinding charge putting into this container with proper viscosity;
4. the lapping device with rotatable motion inserts in the liquid with proper viscosity of container;
5. drive lapping device aligning regular polygon grinding charge and be rotated grinding, and grinding charge is carried out sampling Detection at any time;
6. when the grinding charge sampling Detection reaches the predetermined technique requirement, stop to grind;
7. elimination has the liquid of proper viscosity, cleans grinding charge, to being ground into product collect, dry, storage.
Wherein the 5th step spin finishing process is divided three phases:
1. pre-the grinding, the granularity of the polishing particles of this stage lapping device is moderate, carries out the high speed rotation, with wedge angle and corner grinding, avoids simultaneously causing bursting apart;
2. rough lapping, the granularity of the polishing particles of this stage lapping device is thicker, carries out the high speed rotation;
3. smooth grinding, this stage is adopted polishing lapping device, improves rotating speed if needed simultaneously and grinds.
Implement the suspension grinding device of aforementioned suspension grinding method, at least comprise: one is equipped with the container of the liquid with proper viscosity, a lapping device suspends in the liquid with proper viscosity of this container, other has a rotating driving device, this rotating driving device drives this lapping device rotation by a rotating shaft, this lapping device can be installed in the single face in the described rotating shaft or go up the abrasive disk that bottom surface is evenly equipped with polishing particles for one, can also by a plurality of single faces affixed in the rotating shaft or on, the abrasive disk that bottom surface is evenly equipped with polishing particles constitutes, or is the structure formation of affixed a plurality of abrasive disks in a plurality of rotating shafts; In addition, lay polishing particles or have in the liquid of proper viscosity at the inwall of container and add the effect that an amount of polishing particles also can play grinding.Aforementioned rotating driving device can be made of a motor, is driven the rotating shaft of lapping device or is directly driven the abrasive disk rotation by the rotating shaft of this motor.Described container bottom central authorities also can design the formation that a conical projections or clock breast shape projection is beneficial to rotating vortex.This suspension grinding device also can be fixed by frame, and the upper and lower of this frame is extended with the support arm of a support drive device and the supporting plate of support container respectively.
When abrasive disk rotates under rotating driving device drives, have eddy current that the liquid in rotation of proper viscosity produces and make accurate regular polygon grinding charge rotation and suspend, when grinding charge in rotary course, when touching abrasive disk, grinding charge will be ground.That follows abrasive disk does not stop rotation, the liquid motion with proper viscosity with grinding charge at random mode ceaselessly by the abrasive disk grinding, the corner angle of grinding charge and corner will be ground off at short notice, spheroid or spheroid at last become to be as the criterion.In like manner, the polishing particles of container inner wall also can produce ablation to grinding charge.Can sneak into an amount of abrasive media so that better grinding to be provided in having the liquid of proper viscosity, particularly the surface flatness to grinding charge has effect preferably.
Can provide reliable preliminary working product for the product of manufacturing high-precision requirement with method of the present invention.The high accuracy product is for example: 10 grades or the above spherical eyeglass of optics, the main performance of its product reaches following standard: diameter tolerance: be less than or equal to+/-2.54 microns sphericity: be less than or equal to+/-0.254 micron.The method for example also can be applicable to: pottery, and magnetic material, metal, small ball bearing is used for other material such as accurate ball of flowmeter and the similar processing of product.
