In the field of graphite processing, understanding the differences between natural graphite and artificial graphite is crucial for achieving high - quality and efficient production. This article delves into the processing characteristics of these two types of graphite, especially focusing on the selection of feed rate and cooling method.
Natural graphite and artificial graphite have distinct physical properties. Natural graphite is generally more brittle, with a looser structure. Its brittleness can lead to a higher risk of chipping during machining. On the other hand, artificial graphite has a more uniform and dense structure, which provides better cutting resistance. For example, in a study of 100 graphite samples, natural graphite had a chipping rate of about 15% during rough machining, while artificial graphite's chipping rate was only about 5%.
These physical property differences significantly affect cutting parameters. When it comes to feed rate, for natural graphite, a lower feed rate (around 100 - 150 mm/min) is recommended to reduce the risk of breakage. In contrast, artificial graphite can tolerate a higher feed rate (about 200 - 250 mm/min) without significant damage. Regarding cooling methods, natural graphite requires more gentle cooling to prevent thermal shock, such as using a mist - type coolant. Artificial graphite can withstand more aggressive cooling, like flood - type coolant, to improve heat dissipation and cutting efficiency.
Micro - structure processing of graphite materials faces several pain points. Modeling optimization is the first step. A well - designed CAD model can reduce the complexity of subsequent processing. For example, by simplifying the model, the number of unnecessary tool paths can be reduced by about 20%. In terms of tool path strategies, the choice between spiral down - cutting and straight down - cutting is crucial. Spiral down - cutting can reduce the impact on the tool and workpiece, especially suitable for natural graphite. Straight down - cutting is more efficient for artificial graphite but requires higher - precision equipment.
A real - world customer case can better illustrate these points. A company was processing high - precision graphite parts using natural graphite. By adjusting the feed rate and changing the cooling method from flood - type to mist - type, they increased the良品率 from 70% to 85%. They also optimized the tool path strategy, using spiral down - cutting, which reduced the tool breakage rate from 10% to 3%.
The GJ1417 high - precision CNC milling machine plays an important role in graphite processing. Its advanced CNC system can achieve smooth motion control, ensuring stable processing of micro - structures. For example, it can precisely control the movement of the tool within 0.01mm, which is essential for processing grooves and sharp corners below 0.1mm.
