What is deep hole drilling

What is

HIGH MATERIAL REMOVAL RATE WITH HIGH ACCURACY

Deep Hole Drilling

A deep hole is defined as one that is a minimum of 10 times its diameter in depth. On the maximum side, a deep hole drilling is generally capable of drilling to a depth of 100 to 150 times its diameter. And hole deeper than 10 times the diameter should certainly be considered a deep hole, requiring a specialised drilling technique.

Deep hole drilling are characterized by high material removal rate plus high accuracy with regard to the straightness of the hole, surface finish and dimensional tolerances. The extreme conditions which apply when drilling deep holes place high demands on the tool, machine and associated equipment.

Deep Hole Drilling Systems

Performance Deep Hole Drilling Machine ▸ Made in Taiwan

Gundrilling system

The characteristic of the single flute gundrilling process is that coolant is fed through the coolant hole in the tool and exits along with the chips in the v-shaped groove (flute) on the drill tube from the drilled hole. the coolant also provides lubrication to the drill periphery.

✔ FC Series > Special design for gundrilling Heat Plate. The FC gundrilling machines only has X and Z axis.

BTA single tube system

BTA system is totally different with Gundrilling system. The chips come out from drill tube through tool spindle to conveyor. The BTA system is suitable for drilling larger holes with quicker feeding rate. *BTA has Ejector system and Single tube system. All BTA machines will be used Single tube system in Vastuna.

✔ BV Series > BTA drilling machine for round workpiece and drilling on-center holes.
✔ B Series > BTA drilling machine for round workpiece and drilling on-center holes.

Deep Hole Drilling Methods

Deep hole drilling is the machining of holes with a relatively large depth to diameter ratio. Whereas normal drilling techniques produce holes where the depth is rarely more than five times the diameter. In deep hole drilling the ratio may reach 150 times (depthe/diameter), and any hole deeper than ten times the diameter should certainly be considered a deep hole, requiring a specialised drilling technique.

Deep hole drilling can employ various machine set-ups: rotating workpiece, rotating tool, or both tool and workpiece rotating.

COUNTER-ROTATING TOOL AND WORKPIECE

The best straightness is obtained with counter rotation. Cutting speed is composed by tool and workpiece rotation speed.

ROTATING WORKPIECE

The next best straightness is obtained with a rotating workpiece. Cutting speed is depending on workpiece rotation speed.

ROTATING TOOL

The least straightness is obtained with a rotating tool. Cutting speed is depending on tool spindle speed.

By Drilling system

Gundrilling system

Gun drills (through coolant drill) are straight fluted drills which allow cutting fluid (either compressed air or a suitable liquid) to be injected through the drill’s hollow body to the cutting face. They are used for deep hole drilling—a depth-to- diameter ratio of 300:1 or more is possible.

BTA single tube system

BTA drilling tool heads are threaded or mounted onto long drill tubes, and use multiple cutting surfaces on a single tool to remove chips efficiently, exhausting them using high-pressure coolant through holes in the tool head, then out the drill tube and through the machining spindle. BTA tooling is available in brazed or inserted carbide configurations.
