Specification Brand : GBJ BulletPoint1 : ☞This product is the main accessory of coordinate boring machine, horizontal boring machine, ordinary boring and milling machine, boring and milling CNC machine tools. It can be used for boring, boring outer circle, boring end face, boring stepped hole, boring inner hole end face, cutting inner hole and ring groove on outer circle, etc. BulletPoint10 : Diameter Direct Reading: 0.001" BulletPoint2 : ☞Precise control and free adjustment: The scale of the dial is clear, and the circle is divided into 100 equal parts. The movement of each scale is 0.005mm, the diameter is 0.01mm, and the operation is simple. BulletPoint3 : ☞Select material with high hardness. Using 40CrMo material, it has strong rigidity, special surface treatment, high hardness, good seismic performance, suitable for high speed, and guarantees the density of hole processing. BulletPoint4 : ☞The boring range of the complete set of boring tools: 10-150mm, and the diameter of the boring tool bar is 50mm. Precision fine-tuning: 0.01mm (one revolution of 0.02mm), adjustable stroke 20mm. The boring bar easily and directly enters the boring head hole. BulletPoint5 : ☞The refined boring bar is made of alloy steel, which has strength and toughness, good hardenability, and no obvious temper brittleness. After quenching and tempering, it has obvious impact resistance. The taper design of the bar increases the anti-vibration capability of the boring bar.
