If want to do micro hole processing for some smaller part, must have the stable machine with more higher rotation speed spindle; And the model of RS4-300R micro hole gundrill machine is not only have 10,000 rpm tool spindle ,but also have double-roatation design (tool and workpiece rotation). Customer can drilling minimum hole to 1.5 mm with cone clamping system. This design can save more time on change the workpieces and easy to operate.

Vastuna deep hole drilling machine in Haoway

Vastun deep hole drilling machine

Haoway Precision Co., Ltd.

Haoway Precision Co., Ltd.  was processing the spindle quill at the beginning.

Due to the expansion of the business, they got the deep hole processing case of the hollow cooling ball screw. So that they need to increase more equipment.

After bought the first double rotation machine ( R1-2000R) from Vastuna in 2018, that machine has good performance and high quality to provided the stable quality processing with every order, therefore, the customer decided to increase the demand for production capacity.

Use the machine R1-2000R doble-rotation gun drill drilling machine, the maximum drill depth can be 4500mm ; if want to more rapid productivity, it will need more spindle model of the machine.

According to customer demands, Vastuna started to develop the model R2-1500, which have two spindles, can process two workpieces at the same time. For the demand of the quantitative output, this machine can provide more efficient productivity ; the capacity of the drill depth can up to 3500mm.

After discussed the solution with customer and help them solve the problem, we recommended they purchased the model R2-1500. The customer were incredibly important in our line of business and ordered the R2-1500 machine from Vastuna to solve the problem of insufficient production capacity.

In 2019, Vastuna successful delivery machine R2-1500 double-rotation gundrill machine to Haoway precision Ltd. We insist on offering the best quality to customer from design to finished the machine ; every process all passed the several inspection.. And we also had high repurchase rate on our machine. That is our customer gave us the greatest encouragement and affirmation.

What is “Deep Hole Drilling”?

What is

Gundrilling system machines, Deep hole drilling machines

Made in

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.

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.

Systems

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.

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.
