Problems solved by technology

[0002] At present, the tools for grinding and processing diamond grain lenses cannot make significant progress due to the parameters of heat dissipation, grinding, self-sharpening and life. The disadvantage is that the production efficiency is low and cannot have real productivity. Folding whetstone has good machinability, high processing efficiency, good self-sharpening, strong stability, and good heat dissipation for rough grinding of optical glass lenses, that is, unzipped whetstone

Embodiment 1

[0048] A tool for grinding stones is used in the rough grinding process of optical glass lenses.

[0049] According to the requirements of the client's order for the rough whetstone according to the formula of the present invention, calculate the consumption of various raw materials:

[0050] For example: to produce 20 pieces of Huangzhe whetstones: ×16, the particle size is 270 / 325, and the shape of the Huangzhe whetstone is a hollow cylinder with an outer diameter of 2CM, an inner diameter of 1.6CM, and a height of 1CM.

[0051] A. Calculate the materials used for 20 whetstone rings:

[0052] Volume X Density X Quantity

[0053] (1 2 -0.8 2 ) X 3.14 X 1 X 12 X 20 = 271.296 grams (unit CM).

[0054] B. Calculate the materials used for 20 transitional layers of wasteland whetstones (height is 0.5CM):

[0055] Volume X Density X Quantity

[0056] (1 2 -0.8 2 ) X 3.14 X 0.5 X 10 X 20 = 113.04 grams (unit CM).

[0057] Density definition of the present inventio...

Embodiment 2

[0097] A tool for grinding stones is used in the rough grinding process of optical glass lenses.

[0098] The invention discloses a wild-cut whetstone, which is composed of a whetstone ring 1, a transition layer 3, and a 45# steel matrix 4. The whetstone ring 1 is connected to the transition layer 3 by vacuum hot-pressing sintering, and the transition layer 3 is connected to the 45# steel matrix 4 by high-frequency silver welding.

[0099] There are four cooling grooves 2 equally divided in circumference on the outer edge of the wild-folded whetstone, and the included angle between the cooling grooves 2 and the cooling grooves 2 is 90 degrees.

[0100] The material of the transition layer 3 is pure copper.

[0101] The material of the described whetstone ring 1 is mixed according to the following component ratios:

[0102] Material Specification Ratio

[0103] Titanium alloy powder 300 mesh 10%

[0104] Copper powder 300 mesh 50%

[0105] Iron powder 300 mesh 10%

Abstract

The invention discloses a milling and grinding wheel which comprises a milling and grinding wheel ring, a transition layer and a 45# steel substrate, wherein the milling and grinding wheel ring and the transition layer are in vacuum hot pressing sintering connection; the transition layer and the 45# steel substrate are in high-frequency silver soldering connection; four heat radiating grooves which are distributed circumferentially and uniformly are formed in the outer edge of the milling and grinding wheel; an included angle between every two adjacent heat radiating grooves is 90 degrees; a material of the milling and grinding wheel ring is a titanium alloy binding agent which is formed by fully mixing nonferrous metal powder and diamond micro-powder; and a material of the transition layer is pure copper. Remarkable technological improvements on the milling and grinding wheel are as follows: the cutability is good, the processing efficiency is high, the self-sharpening performance is good, the stability is high, and the heat radiating performance is good.

Description

technical field [0001] The invention belongs to the technical field of processing optical glass lenses, in particular to a rough grinding processing tool for optical glass lenses. Background technique [0002] At present, the tools for grinding and processing diamond grain lenses cannot make significant progress due to the parameters of heat dissipation, grinding, self-sharpening and life. The disadvantage is that the production efficiency is low and cannot have real productivity. Zhe whetstone has good machinability, high processing efficiency, good self-sharpening, strong stability, and good heat dissipation for rough grinding of optical glass lenses, that is, unzipped whetstone. Contents of the invention [0003] In order to overcome the lack of heat dissipation, abrasiveness and self-sharpening of the prior art tools for grinding and processing optical lenses, a slotted whetstone is invented to improve heat dissipation, good machinability and high processing efficiency...
