Welcome To Hayagreevaya Enterprises

A deep hole is defined by its depth-to-diameter ratio (D:d), and typically holes greater than 10:1 are considered deep holes. Deep hole drilling into metal has a range of applications across several industries, with its origins tracing back to the need for straighter, more accurate gun barrels, and expanding as other industries integrated deep hole drilling processes to improve their own applications. Deep hole drilling consists of BTA drilling and gun drilling, with additional processes designed for specific tolerance objectives and generally performed on BTA-style deep hole drilling machines. Deep hole drilling is used in a variety of materials from aluminum to super-alloys, and is capable of achieving tight diameter control, straightness, and superior surface finish into workpieces.

Deep hole drilling processes work by using special tools and setups to deliver high pressure 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.

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 up to a limited depth-to-diameter ratio.

We are offering services to pan India and Abroad, the drilling minimum Dia12mm toDia 110mm, drill depth up to 3 mtrs, accuracy of 30 microns along with mirror finishing.

DHD3 is a machine with 2 heads(spindles) that can work independently in parallel. The machine was built in-house and is a prime example of the precision engineering , design and execution, capabilities. The machine involves servo control and motion control in multiple axes with high accuracy and precision. The machine is capable of drilling holes up to 3000mm deep and 110mm wide.

Our facility prides in having 5 VMC machines and can accommodate large amount and variety of works with all 5 VMCs working in parallel. The specifications of Our VMC machines are given below:

Motion Details:

VMC machines are using a 2D, 3D, milling , boring , drilling and angle profiles. a typical Vertical Milling Center (VMC). Parts to be machined are fastened to the machine table. This table moves in the XY-Plane. As the operator faces the machine, the X-Axis moves the table left-right. The Y-Axis moves the table forward-backward. The machine column grips and spins the tool. The column controls the Z-axis and moves up-down.

Plano Milling Machine is widely used in industries for precise shaping of metals & various solid materials. These entire machines are ideal for various processes such as slot cutting, routing in metallurgy industry.Hayagreevaya Enterprices has 2 Plano Milling Machines and is capable of handling different types of jobs owing to the same.

Our Radial Drilling Machines are armed with light centering spindle, ergonomically grouped controls, precise depth release, electrohydraulic clamping for drillhead, arm and sleeve; shock free engagement of taps etc.

Specifications:

Oxy-fuel cutting use a combination of fuel gases and oxygen to cut metals. A variety of different fuels may be utilized, although the most common is acetylene. Other gases utilized include natural gas, propane, hydrogen, propylene, liquified petroleum gas (LPG), and combinations of these gases.

Oxy-fuel cutting begins by using a torch to heat a metal to its kindling temperature. This is the lowest temperature at which the metal in question will spontaneously ignite. At this point, a stream of oxygen is trained onto the metal, in turn burning it into a metal oxide. This new metal oxide then flows out and away from the intact material being utilized. Any leftover slag can be wiped or tapped away. It’s actually the heat produced by the metal oxide and its contact with the rest of the material which actively continues the cutting process. The torch itself only heats the metal to begin the process.

Unit2 houses a Oxy Fuel Cutting Machine which is equipped with features to ensure high level of control and precision.
