The gradual trend of the lighting market is gradually changing. With the general decline in the price of LED bulbs and the rising awareness of consumers, the penetration rate of LED lighting will further increase. In the backlight market, the new round of home appliance subsidy policy is unclear, and orders are falling. Some LED manufacturers' revenues have declined, and the backlight market economy has declined from the previous month. With the coming of the Lunar New Year, the stocking demand of traditional holiday makers will provide some support for the performance of LED manufacturers, and the overall trend of the LED market is still upward.
The LED boom continued and the overall upward trend remained unchanged. In September, the total revenue of listed LED manufacturers in Taiwan fell by 1 to 11 billion Taiwan dollars, of which Taiwan's LED chip makers' revenues reached 3.86 billion Taiwan dollars, while Taiwan's LED packaging manufacturers' revenues reached 7.17 billion Taiwan dollars.
Apple's new tablet iPadAir and iPadmini are not lacking in highlights. Combined with the iPhone and iPhone 5s and 5c's first-week shipments exceeding expectations, Apple's new tablet sales will exceed market expectations, focusing on Apple's sales exceeding expectations and the double benefit of the industry chain: Goer Acoustics, Desai battery, Xinwangda, Anjie Technology, Crystal Optoelectronics, Lixun Precision; LED in the cycle of driving demand led by the trend of the upward trend, Sanan Optoelectronics, Sunlight and other leading stocks significantly benefited.
CNC Milling is to use the rotating multitool to cut workpieces, such processing method is efficient. Tool rotate (background) while working, and the workpieces move (as a feed movement), workpieces can also be fixed, but at the moment, rotate tool must also move (at the same time to complete the main motion and feed motion).Milling machine has a horizontal milling machine or vertical milling machine, large gantry milling machine.The machine tool can be ordinary machine tool, can also be a nc machine tools. With rotating cutter as a cutting tool.Milling is generally conducted on milling and boring machine, suitable for processing plane, groove, all kinds of forming surface (such as spline gear and thread) and special shape mould surface, etc
The characteristic of the CNC Milling is:
(1) cutter blade periodically participate in continuous cutting.
(2) each blade in the process of cutting, cutting thickness is variable.
(3) each tooth feeding alpha f (mm/teeth), said cutter every turn a blade workpieces relative displacement of time.
