Deep Hole Drilling Machines

What are deep-hole drilling machines?

Deep hole drilling is a machining process in which holes are created up to ten times deeper than the hole diameter. Suitable for a range of metals, including the strongest of superalloys, deep hole drilling is used in many fields, including oil and gas generation, aerospace, and heavy industry.


How are deep-hole mold-making drilling machines used?

Deep hole drilling is generally performed on dedicated deep hole drilling machines which are manufactured and assembled to optimize the processes for straightness and efficiency. Advances in technology allow CNC machining centers, equipped with high-pressure, through-spindle coolant, to be capable of gun drilling deep-hole up to a limited depth-to-diameter ratio. Precihole Machine produces highly capable BTA drilling machines, gun drilling machines, and facing and centering machine with applications exceeding 400:1 D:d ratios.

Deep hole drilling processes work by using special tools and setups to deliver high-pressure gun drilling coolant, evacuate chips cleanly, and achieve depth-to-diameter holes into metal beyond what a common CNC machine can reach. This allows manufacturers to achieve their manufacturing tolerances and production requirements reliably, accurately, and efficiently.

What are the advantages of deep-hole drilling machines?

Deep hole drilling machines are ideal for a variety of sizes of deep holes and production levels and are necessary for holes that are approximately 20:1 depth-to-diameter or greater in ratio. Dedicated deep hole drilling machine provide tooling support, coolant delivery, and process feedback that allow manufacturers to achieve their deep-hole drilling goals. These features optimize the process and prioritize deep hole drilling methods, by reducing cycle time, stabilizing tooling, evacuating chips, and preventing tool breakage and process failures, when compared to CNC machining centers.

These deep hole drilling tools hold location to accurate tolerances, generate burr-free holes, and are sized to precise specifications. They can also be formed, deep-holeAdditionally, this operation creates accurate, repeatable holes with outstanding surface finishes, which eliminates the need for one or more secondary or finishing operations.

What is Facing and Centering Machine?

Image
 FCVN Series Facing & Centering Machines Precihole manufactures a special purpose, highly versatile machine for facing and chamfering barrel blanks. Accuracy in these operations is critical for the barrel blank to be located and aligned properly in the cone clamping system on gun drilling and pull reaming machines. If the barrel is improperly faced or chamfered, the barrel does not seat properly in the cone leading to inaccuracies in the gun drilling operation. This machine engages the component simultaneously at both ends. The combined facing and chamfering operation use a special tool that ensures high productivity. Two hydraulically operated self-centering work holding vices hold the barrel blank accurately. Total cycle time is generally less than 30s. Automation for loading and unloading barrels can be added as an option on the machine. Facing and Centering Machine  Features Use of ball screw and servo drives for linear motion Simultaneous facing and chamfering operati...

What is Honing Machine Process?

Image
Metalworking is a process that uses machinery to shape or cut metal. There are a variety of different methods for doing this, but one of the most popular is honing machine process. This process uses a specially designed machine to create a smooth, consistent surface on metal parts. The honing machine can be used on a variety of different metals, including steel, aluminum, brass, and copper. Honing machines are tools designed to clean and smooth metal using hard tools and rough stones as abrasives. The honing process was developed to allow for the improvement of bore geometry, size control, surface finish, and surface structuring. The honing process provides the final sizing and uses the specified surface finish in the interior of a tubing or cylinder bore. Finishing is accomplished by using abrasive stones of suitable grit and grade to polish the work surface. The stones are rotated and reciprocated on the rock grinder under controlled pressure to produce cross-hatch patterns on the s...
