Likai Technology Co., Ltd.
Li Kai launched a multi wire cutting sapphire saw
[China machine tool business] Shandong Li Kai Electronic Technology Co., Ltd. for LED substrate material industry capacity bottleneck problems, launched a series of a variety of multi line cutting machine, the comprehensive performance of equipment basic and Japanese equipment comparable, widely praised by customers.
Multi wire cutting machine is an important component of LED industry chain, which is mainly used in cutting process of LED substrate material (such as sapphire, Si, silicon carbide, etc.).
On the development direction of the industry, high material utilization, low cost of large size sapphire crystal is one of the development direction of the industry. At present, China put into operation of LED sapphire substrate of about 30 enterprises, production capacity of more than 100 million pieces / year, has exceeded the global demand.
Along with the expansion of demand, the problem of LED substrate material industry capacity bottleneck is highlighted, and the material cutting equipment with high precision, high efficiency, low cost and high investment return can effectively alleviate this problem. However, in reality, due to the technical monopoly and other issues, the domestic multi wire cutting machine technology has long been a bottleneck, domestic manufacturers rely more on imports.
In order to change this situation, Li Kai Electronic Technology Co., Ltd. after years of research and development, successfully developed a series of a variety of multi line cutting machine, after repeated process equipment test, improvement and promotion, a put on the market, will get the customer's wide acclaim.
LKCA400 type rolling line cutting machine is a kind of multi line cutting machine which is specially designed for the super hard brittle materials such as sapphire, which has the advantages of high cutting efficiency, high cutting precision, high detection precision, control precision, stable operation, environmental protection and energy saving.
LKCA400 multi line cutting machine Innovation by roller side removing structure, simple operation, to replace a Luo pull only 0.5 hour, a domestic removing roller the shortest time, domestic machine replacement roller time is 2 hours; roller adopts double cone positioning, so that the front and the back of the concentric, to ensure the concentricity of the front and the rear positioning, the operation is stable without beating, to ensure that the cutting quality.
First use of domestic 10 wire guide wheel structure, guide pulley diameter is 120mm, wire radius increased significantly and reduce the degree of bending of the steel wire, and guide a substantial reduction in the number, the greatest degree of reduced rate of disconnection.
The first spindle adopts water cooling sleeve structure, the bearing is sealed the installation of a maintenance free structure, strong ability of water
To ensure the use of the equipment in high speed operation of the bearing environment, increase service life; (oil cooling or oil mist cooling post maintenance costs are high, and have a certain impact on the bearing, high accuracy of imported equipment are used in maintenance free program).
In addition, precision cable automatic induction system by the steel wire pull of the timely feedback signal, fast response and accurate detection, cable tracking stability; unique disconnection protection system, in any position as long as there is a broken thread immediately shutdown protection, avoid disconnection continues to run, to prevent the roller surface have a greater damage. The original machine roller in continuous thread must move to both ends in order to alarm.
The performance of LKCA400 multi line cutting machine is basically comparable to that of Japanese equipment, cutting precision and cutting yield even exceed import equipment. At the same time, it can also be tailored for different manufacturers of process requirements, customized combination, comprehensive cost of equipment.
