Gun drilling is a precision process where accuracy must be maintained over long distances and through a wide range of materials. Consistency, straightness, and internal finish are critical, particularly when holes form part of a functional internal feature rather than a visible surface. At LDC Engineering Ltd, gun drilling accuracy is achieved through specialist equipment, experienced engineers, and controlled machining processes.
Specialist Machinery Designed for Gun Drilling
Gun drilling accuracy begins with using machinery designed specifically for deep, precision bores. LDC Engineering provides gun drilling up to 38mm diameter, with depths of up to 4 metres achievable on certain diameters. This type of drilling cannot be carried out reliably on standard machines, which is why dedicated gun drilling equipment is essential.
By using purpose-built machines, LDC can control drilling stability and maintain consistent bore alignment over extended depths, supporting components that require tight internal accuracy.
Experienced Operators and Process Control
Gun drilling accuracy depends heavily on the skill and experience of the engineers operating the machinery. LDC Engineering specialises in subcontract gun drilling and deep hole drilling, meaning their team works with precision drilling processes on a daily basis.
This experience supports accurate setup, correct tool selection, and controlled drilling across both simple and complex components. From straightforward heater holes to more advanced internal features such as multi-level water circuits, consistency is maintained throughout the drilling process.
Accuracy Across a Wide Range of Materials
Different materials respond differently during gun drilling, which can affect accuracy if not properly managed. LDC Engineering machines a broad range of materials including duplex, stainless steel, mild steel, aluminium, copper, bronze, cast iron, cast steel, resin, nylon, and wood.
This material versatility requires an understanding of how each material behaves under deep drilling conditions, helping ensure drilled holes remain accurate and repeatable regardless of material type.
Supporting Accuracy with In-House Machining Services
Gun drilling at LDC Engineering is supported by additional in-house machining services, including deep hole drilling, CNC milling, turning, radial drilling, and surface grinding. Their surface grinder includes a large table size of 1500mm x 500mm x 350mm, supporting accurate finishing where required.
By completing multiple machining stages in one facility, LDC helps maintain consistency between drilled features and other machined surfaces.
Consistent Results Through Specialist Focus
Gun drilling accuracy is achieved through a combination of specialist equipment, experienced operators, and controlled processes. LDC Engineering Ltd focuses on subcontract gun drilling and deep hole drilling, supporting customers who require reliable, repeatable results across both one-off components and batch production.
For gun drilling requirements where accuracy matters, LDC Engineering provides a focused and experienced solution.
