The ratio of a hole’s depth to its diameter (D: d), and typically, holes with a ratio greater than 10:1 are regarded as deep.
The need for straighter, more precise gun barrels led to the development of deep hole drilling, which expanded as other industries incorporated deep hole drilling processes to enhance their own applications. Deep hole drilling into metal has a wide range of applications in a variety of industries.
Profound opening boring comprises BTA penetrating and firearm boring, with extra cycles intended for explicit resilience goals and by and large performed on BTA-style profound opening boring machines.
From aluminium to super-alloys, deep hole drilling is used to control the diameter of workpieces, ensure straightness, and provide a superior surface finish.
Processes for deep hole drilling work by delivering high pressure coolant, efficiently ejecting chips, and drilling holes in metal that are deeper than a standard CNC machine can reach.
Manufacturing tolerances and production requirements can be met reliably, accurately, and effectively thanks to this.
The Global Deep Hole Drilling Machines Market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
The B850 is a brand-new deep hole drilling machine from UNISIG’s B-series.
UNISIG evaluated all previous designs when developing the B850. The bed and rack-and-pinion system were kept, and feed systems were updated to make them more rigid and less likely to backlash. A new three-range, automatically shifting headstock featured a helical-geared, high-performance transmission.
The machine’s construction was made simpler by incorporating cutting-edge ideas for gearing and the power train. As a result, the machine cost less money and performed better.
A standard programmable coolant system is also available on the B850. The machine’s user-friendly controls and other new design features allow the operator to concentrate on the part being machined rather than managing numerous manual functions.
For the high power and high torque required to drill holes up to 180 millimeters (7.1 inches), both the work and tool headstocks provide 166 horsepower. 221 millimeters (8.7 inches) in nickel alloys in steel with carbon, and 320 mm (12.6 in.) with counterboring. The machine can drill to maximum depths of 1.98 to 19.81 meters (78 inches). to 65 ft).
The B850 is a product in the UNISIG B-series that is made to drill round workpieces on center in aerospace, defense, and oil and gas applications.
These machines are able to perform counterboring, trepanning, skiving, and roller burnishing, in addition to the standard BTA drilling techniques, to the exacting tolerances required by manufacturers in these and other industries.
DD40E/2 FINCM CNC Double-Spindle Horizontal Deep Hole Hydraulic Drilling Machine.This machine is primarily made up of a longitudinal sliding table, a vertical column sliding table, a double-spindle feed sliding table, a worktable and bending plate, a hydraulic system, a cooling system, an automated lubrication system, an electrical system, and a chip conveyor, among other things.
This DD40N/2 is primarily used for drilling holes in the tube plate of shell and tube heat exchangers used in the petroleum, chemical, pharmaceutical, thermal power station, nuclear power plant, and other sectors. The maximum workpiece diameter is 4000mm (must be rotated 180°), and the maximum drilling depth is 750mm.
