Quality Carbide Center Drill Bit for Metal Application of center drills
Center drill bits, also known as Slocombe drill bits, are used in metalworking to provide a starting hole for a larger-sized drill bit or to make a conical indentation in the end of a workpiece in which to mount a lathe center. In either use, the name seems appropriate, as the bit is either establishing the center of a hole or making a conical hole for a lathe center. Nevertheless, because of the frequent lumping together of both the terminology and the tool use, suppliers may call center drill bits combined-drill-and-countersinks in order to make it unambiguously clear what product is being ordered.
1). Center drill types are commonly used to drill holes which provide small diameters. Mostly used to create pilot holes, they are very useful as they can guide the worker to correctly perform the holes he needs. Once the hole is located in the right place, the center drill has to be replaced with a normal drill which provides the right diameter. However, in order to use the center drill, you have to provide the proper lubricant so that the drill`s tip is not going to be twisted off while performing a specific task.

When interviewing Professor Li Yinjiang in China Superhard Materials Network, Professor Li Yinjiang said: This formula design program directly supports industrial production. The program directly gives the application formula of the abrasive tool for the requirements of the mechanical industry production. It is not an air-to-air argument and has a strong practicality. The main application is in four aspects:
(1) Abrasives of various hardnesses of brown fused alumina, white corundum, chrome corundum, black carbonized green silicon carbide abrasives, and diamond and CBN superabrasive ceramics, which provide ceramic binders and resin binders for abrasive tools manufacturers. Abrasives for various uses of agents, resin binders, and metal binders;
(2) Providing specific parameters for ordinary abrasive tools and superhard abrasive tools required for processing various mechanical parts for the machinery manufacturer of the abrasive tool;
(3) Providing the product parameters of the ordinary abrasive tools and superhard abrasive tools required by the user for the sales department of the abrasive manufacturing factory;
(4) Provide specific product parameters for ordinary abrasives and superhard abrasives suitable for grinding for the purchaser of the abrasive tool user.
After the launch of the newly upgraded formula design program, it has received great attention and registration from the vast abrasives industry. As of press time, the reporter was informed that in order to ensure the quality of training, and due to factors such as training venue restrictions, this training is limited to 50 people, and only a small number of places are currently available. It is hoped that relevant enterprises will inform each other and seek registration as soon as possible. (Registration method: click to enter )
Advantages of formula design program for superhard material metal bond and common abrasive ceramic and resin bond abrasives:
1, originality. The program was compiled by Professor Li Yinjiang for more than 50 years of production and teaching experience and accumulated information in the abrasives industry. No similar or identical applications have been found.
2. Directly support industrial production. The program directly gives the application formula of the abrasive tool for the requirements of the mechanical industry production. It is not an air-to-air argument and has a strong practicality.
3, the program is rich in content. The formula can be applied to the application formula of 17 major items such as automobile, bearing, tool and civil. It can choose various kinds of abrasives such as brown fused alumina, white corundum, black silicon carbide and green silicon carbide, and diamond, CBN and so on. Hard abrasive, using ceramic, resin, metal bond abrasives, with 12,000 recipe points and more than 1000 specific application formulations, the actual formula can be produced far more than this number.
4. Summary of history. After the 1950s, China's machinery industry developed rapidly. With the development of the machinery industry, the abrasives industry has also closely followed and received help from the former Soviet Union and the former East German countries. The information on grinding and processing has also received attention. Prof. Li Yinjiang collected the application materials of abrasive tools from the early 1960s to the 1990s. Based on the Technical Manual of Abrasives and Abrasives (published in 1993), the author compiled and compiled this procedure with certain authority.
5. Advanced. The program can be used online throughout the country through the Internet, regardless of regional restrictions, easy to promote throughout the country, and can be upgraded at any time! The recipe obtained by the user through the program is confidential, is not known to anyone other than the user, and protects the user's technical secrets.
The appearance of the ceramic resin bond abrasive formula design program has greatly improved the core of the abrasive manufacturing - the efficiency of the formulation design work, and meets the needs of the abrasive manufacturer, which can be said to be a good helper for the manufacture of abrasive tools.
