In industries that demand multi-dimensional accuracy, such as aerospace, medical, mold & die, and energy systems, the need for flexible deep hole drilling has become more critical than ever. When components feature angled, multi-point, or variable-position bore holes, a conventional fixed-axis machine may not suffice.
This is where the Knee Type 3-Axis Deep Hole Drilling Machine from Shin-IL Machinery shines—offering manufacturers a versatile, high-precision platform that supports deep hole drilling across three programmable axes (X, Y, Z). Built with adaptability and structural integrity at its core, it enables complex, multi-directional hole machining in a single setup.
What Is a Knee Type 3-Axis Deep Hole Drilling Machine?
The Knee Type 3-Axis Deep Hole Drilling Machine is an advanced deep hole drilling system equipped with three linear axes of movement: longitudinal (X), vertical (Y), and cross-feed (Z), along with a vertically adjustable knee-type worktable.
This configuration allows precise positioning of the workpiece and tool head, making it ideal for parts with:
Multiple hole positions
Off-center bores
Angled drilling paths
Asymmetric structures
Unlike standard 1-axis deep hole drilling systems that are limited to straight-line drilling, this machine offers full flexibility to accommodate multi-angle and offset hole requirements with minimal repositioning.
Key Features of Shin-IL’s Knee Type 3-Axis Drilling Machine
Independent 3-Axis CNC Control
Each axis is independently programmable via CNC (Fanuc or Siemens), allowing for highly customizable drilling paths and easy automation of complex hole patterns. This ensures precision alignment and repeatability across multiple parts.
Heavy-Duty Knee Table Design
The knee-type table provides vertical travel (Y-axis) for tool positioning while also supporting large and heavy components. This structure minimizes vibration and maintains rigidity during deep hole operations.
BTA & Gun Drilling Compatibility
The machine supports both BTA and gun drilling processes, depending on hole diameter and depth requirements. It is ideal for machining deep holes with high L/D ratios, even in materials such as stainless steel, titanium, and hardened alloys.
Integrated High-Pressure Coolant System
A built-in high-pressure coolant system ensures optimal chip evacuation and temperature control, improving surface finish, tool life, and operational efficiency.
Multi-Material Capability
Suitable for drilling high-precision holes in:
Die steel & tool steel
Aluminum & non-ferrous alloys
Titanium & heat-resistant superalloys
Hardened aerospace-grade materials
Typical Applications
The Knee Type 3-Axis Deep Hole Drilling Machine is the ideal solution for:
Mold & Die Components: Cooling channel drilling in multi-face or stepped molds
Hydraulic & Pneumatic Parts: Drilling cross-holes and intersecting ports in manifolds
Medical Implants & Tools: Angled holes in orthopedic implants or bone reamers
Aerospace Parts: Multi-directional bores in structural and engine components
Defense Equipment: Barrel, breech, and breach ring drilling in artillery systems
Its ability to drill accurately positioned bores from multiple angles without re-clamping saves time, improves accuracy, and reduces the chance of error in complex part geometries.
