Boring Bars
Boring bars by Dorian Tools are designed to enlarge a pre-drilled hole / cast by turning the inner diameter of the hole. These tools can work to any diameter by adjusting the speed, feed and nose radius and allowing a right- / left-handed operation as per user convenience. These Dorian turning tools feature a circle multi-lock / clamp-lock / screw-lock mounting which provides an easy-to-change insert facility and a secure connection to reduce vibrations. The round shanks of these boring bars are made of carbide / steel and are offered within the diameter range of 0.375 - 2.5 inches. For different applications, a wide range of shims are available to correct the inclination of the lead angle with the flank angle of the threads.

Features
- Raptor Supplies offers a variety of left-hand and right-hand Dorian boring bars for various internal machining applications and for enlarging existing holes.
- Boring bars are typically longer than drill bits, resulting in a larger surface area for vibrations to occur.
- Due to their dense structures, these units provide a more stable cut when an axial force is applied.
- Selected units have a shallow thread that does not run the length of the unit. When compared to a drill bit, this thread pattern can generate more vibrations through the boring bar, resulting in a tighter seal in the interior of the material being bored.
Working Mechanism
- Boring bars have the main body that is attached to and rotated by the milling sleeve of the machine tool.
- A precision mechanism within the main body moves back and forth, actuated by the linear movement of the machine tool boring spindle.
- Due to the rigidity of the boring bar and the precision of its internal mechanism, the tool accurately reflects the contouring capabilities of the machine tool to which it is attached.
Frequently Asked Questions
What are the requirements for installing the boring bar on a machine?
- The lateral movement of the boring bar should be under CNC control.
- The machine tool's table or column should move in the same direction as the boring bar.
- The boring spindle and milling sleeve should rotate in unison.
How do you stop boring bars from chattering?
- Slow down the cutting speed.
- Increase the depth of the cut (Rule of thumb is at least your tool nose radius).
- If possible, increase the feeding rate.
- Select a tool with a smaller nose radius.
- Reduce the stick out of the bars.
How do I stop my boring from vibrating?
A variable stiffness dynamic vibration absorber (DVA) is added inside the boring bar to reduce vibration and thus improve the performance of boring operations. The DVA's stiffness is provided by two rubber bushes located within the DV
