Embodiment 1
[0035] Embodiment 1: Polishing the surface of a 100×50×10mm jade slab.
[0036] Auxiliary materials: sintered magnetic abrasive, water-based grinding liquid, diamond grinding paste, iron powder, cleaning agent.
[0037] ① Cleaning: First, use an ultrasonic cleaning machine to add a small amount of cleaning agent to clean the surface of the jade slab, remove the surface stains of the jade relief crafts, and dry it;
[0038] ②Clamping: Fix the jade plate to be processed on the fixed workpiece table 10 of the numerical control auxiliary frame of the ultrasonic magnetic composite grinding device. The fixed workpiece table 10 is a magnetic material, which can be formed with the permanent magnet 6 after magnetization closed magnetic circuit;
[0039] ③Parameter setting: start the ultrasonic generator 7, set the frequency of ultrasonic generation to 15-20KHz, and the amplitude to 10-20μm;
[0040] ④ Coarse throwing: Mix the sintered magnetic abrasive with a particle size of 250-350...
Embodiment 2
[0046] Embodiment two: to the surface polishing of Buddha statue jade carving handicraft.
[0047] Auxiliary materials: sintered magnetic abrasive, water-based grinding liquid, diamond grinding paste, iron powder, cleaning agent.
[0048] ① Cleaning: First, use an ultrasonic cleaning machine to add a small amount of cleaning agent to clean the surface of the Buddha statue jade carving handicraft, remove the surface stains of the Buddha statue jade carving handicraft, and dry it;
[0049] ②Clamping: Install the Buddha statue and jade carving handicraft to be processed on the fixed workpiece workbench 10 of the numerical control auxiliary frame of the ultrasonic magnetic composite grinding device. 6 to form a closed magnetic circuit;
[0050] ③Parameter setting: start the ultrasonic generator 7, set the frequency of ultrasonic generation to 15-20KHz, and the amplitude to 10-20μm;
[0051] ④ Coarse throwing: Mix the sintered magnetic abrasive with a particle size of 200-250 μm ...

Abstract
The invention belongs to the technical field of stone processing, particularly relates to an ultrasonic wave and magnetic force composite grinding device for a jade emboss craftwork and a grinding process. The grinding device comprises a numerical control auxiliary machine frame, as well as an ultrasonic wave generating mechanism and a magnetic force grinding mechanism which are arranged on the auxiliary machine frame, the ultrasonic wave generating mechanism comprises an ultrasonic generator, a piezoelectric transducer, an amplitude transformer and an elastic cylinder clamp, wherein a collecting ring is arranged on the outer side of the piezoelectric transducer, the piezoelectric transducer is connected with a driving main shaft on the numerical control auxiliary machine frame, and the magnetic force grinding mechanism comprises a permanent magnet and a magnetic grinding material. According to the invention, ultrasonic wave vibration is used for forming impulse pressure on the surface of jade, the magnetic grinding material can be used for effectively improving the processing efficiency and the processing quality to the concave-convex surface of the jade under the composite effect of magnetic force and impulse pressure, mechanical polishing to the jade emboss craftwork can be achieved, and defects of manual polishing are overcome.
Description
technical field [0001] The invention belongs to the technical field of stone processing, and in particular relates to an ultrasonic-magnetic composite grinding device and a grinding process for jade relief handicrafts. Background technique [0002] For jade handicrafts processed by hand or machine, polishing is the last process of processing technology, and it is also the most important process of jade handicrafts processing. However, there is no special polishing equipment for the polishing of jade relief handicrafts, and manual polishing is often used for the unevenness of the surface of jade relief handicrafts. The polishing process is cumbersome, labor-intensive, and the working environment is harsh. At the same time, the surface quality is uneven after manual polishing, and the processing efficiency is low. Magnetic grinding is a new type of grinding method. The difference from traditional grinding methods is that the grinding tools used in magnetic grinding are loose ...
