 ZI- Type machine clamp BTA deep hole drilling head   is adopt inner discharge chip , the drilling heads diameter size from *0mm***0mm , BTA drill blade body adopt material imports with high strength and heat-treated steel ,more than 2 times higher than that of common drilling heads service life.guide block using hard alloy material processed ;BTA drilling head useing the high quality blade, its can be drilled hole in the carbon steel, alloy steel, aluminum , *5 # steel and other solid materials, length to diameter ratio up to  1:**0

 

2.Advantages: BTA drilling head for processing high efficiency, high durability, easy to install;

 

**1 , The selection of cooling liquid

Oil: according to the following reasons, the oil as the recommended preferred

(1)longer tool life. Choice of cutting oil or emulsion is very significant difference. Usually cutting oil, tool life can be extended to *0%

(2)Better off consistency and a wider range of cut

(3)When applying the emulsion, if the machine continuously, there is a danger of stagnation. When the machine is idle, the cooling tank should be ventilated to prevent the loss of activity of **2, Emulsion: as the recommended second options

Advocate the application of emulsion based on the following points:



(1) If drilling on the production line or in the central system on some of the machine tool, the application of pure oil will become complicated



(2) Drilling in machining center, the most drilling for high-speed processing is the  subsidiary operations.



(3) It can use the emulsion to the cleaning work-piece during

processing.If the use of oil, in the next process or storage, and sometimes need to clean the workpiece to remove oil.
