Precihole Machine Tools Pvt. Ltd.

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

Deep hole drilling is often used to access metal through a small hole in the ground. The metal is then. The metal is then advoaded into a tool that can be used to remove it from the surface.

Precihole manufactures a compact and precise straightening press for gun barrels. Barrel black straightness is a very important factor that determines the accuracy of the weapon system. Barrel is long slender shaft that is likely to bend during many stages of heat treatment and machining it goes through all the way from bar stock to a gun ready profiled and chambered barrel. A Precihole press allows straightening of all blank OD's from Ø20mm to Ø60mm and lengths of up to 1500mm. It is very simple and does not require any special operator skills.

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.

BTA stands for Boring and Trepanning Association which developed this deep hole drilling system. It involves a single drill tube in which high-pressure coolant is supplied to the drill through the annular area between the drilled hole and the tube's outer diameter. The chips are evacuated through the I.D. of the tube. The drill head is screwed to this drill tube which is much stronger compared to the kidney-shaped shank of a gun drill, hence much higher metal removal rates are possible. This involves the use of a Pressure head which is basically a high-pressure seal between the workpiece and the drill bush. BTA/STS drilling is generally used for ф19 and above.
