How are milling cutters, drill bits, and step drills produced?
2017-04-18
Gold powder every day with the machine tool to deal with, do you know the daily use of the milling cutter, drill, step drill is how to produce it? Xiao Bian today
Find a few videos, to share with you, of course, this is only a few pieces of video production tools, can not represent all of the relevant information
The find is limited, if a gold powder processing for various types of tools to understand words, welcome message or contribute to our ~ ~ ~ ~ oh
Milling cutter
Milling cutter is a rotary cutter with one or more cutter teeth for milling. Each in turn cutter tooth intermittently cut work
Margin. The milling cutter is mainly used to process the plane, the step, the groove, the forming surface and the cutting work piece on the milling machine and so on. Cylindrical milling cutter,
Face milling cutter, vertical milling cutter, three face milling cutter, angle milling cutter, saw blade milling cutter, T milling cutter, etc.. But how to make the milling cutter
Let's look at the video!
Bit
The rolling process is widely used in the forming of the bit. The biggest advantage of this technology is the high production efficiency, can make full use of raw materials; processing
The inner structure of the bit body of the drill bit has the continuity of the fiber, the grain is refined, the carbide is evenly distributed, and the red hardness is high. But the rolling process is also clear
Obvious defect, that is, the drill body is easy to crack. Under normal circumstances, the fracture rate of the drill bit is 5% ~ 10%, sometimes up to 20% ~ 40%, only
Due to the loss of hundreds of thousands of dollars. Especially in the case of the high price of high speed steel material, to solve the problem of bit crack,
Reduce the cracking rate, will enable enterprises to obtain greater economic benefits.
Step drill
Step drill also known as step drill or pagoda drill, mainly used in 3mm within the thin steel drilling, a drill can replace the use of multiple bits
The utility model can be used for processing the holes with different diameters according to the requirements, and the utility model can realize the one-time processing of large holes, and does not need to replace the drill bits and the positioning holes.
Ladder drill also known as step drill or pagoda drill (English name Step Drill), mainly for 3mm within the thin steel drilling, a drill
The utility model can be used as a substitute for a plurality of drill bits, and can be used for processing the holes with different diameters according to the requirements
Head and positioning holes.
Product manufacturing: at present, the overall ladder drill using CBN full grinding manufacturing, materials mainly for high-speed steel, carbide, etc., high processing precision,
According to the different processing conditions, the surface coating can be used to prolong the service life of the tool and enhance the durability of the tool.
Classification of products:
According to the groove shape of the product, it can be divided into three types: straight groove, spiral groove and arc slot.
According to the number of products can be divided into single blade, double edge, three blades, four blades and multi - edge ladder drill.
