Our series of products represented by Carbide Boring Bar have won the love of our customers with strict production technology and superior quality!
The boring bar is the connecting rod of the boring machine, the deep hole drilling and boring machine and the corresponding drill bit, boring head, rolling head and combined boring and rolling head.
The length of the single-section rod is 0.5 meters, 1.2 meters, 1.5 meters, 1.7 meters, 2 meters, etc., to suit the needs of different machine tools and different processing depths.
The boring bar is made of alloy. Generally, 40Cr is used, and 45 steel is also used. Some anti-vibration boring bars are made of tungsten steel and made of full tungsten carbide, which has excellent rigidity and good shock absorption. These materials must be forged and then normalized, and then quenched and tempered after rough machining. The hardness reaches Rockwell HRC28-33, and they are processed into standard toolholders with high strength and good shock resistance.
