Bore Machining

Precision bore machining services for industrial components requiring tight tolerances and superior surface finishes. Our boring capabilities cover a wide range of bore sizes, depths, and configurations. Whether you need a simple through bore or a complex stepped bore with internal grooves, we have the expertise and equipment to deliver.

Bores are among the most critical features in mechanical components, often serving as bearing surfaces, seal surfaces, or alignment references. We ensure every bore we machine meets the highest standards of accuracy and finish.

Our Bore Machining Services Include:

• Internal Bore Machining: Precision boring of internal diameters using lathe boring bars and boring heads for accurate hole sizing and finishing.
• Precision Boring: Fine boring operations for achieving tight tolerances (up to H7 fit) and excellent surface finish for bearing housings and precision components.
• Through Bore & Blind Bore: Boring of both through holes and blind holes with flat bottom or profiled bottom as per requirements.
• Step Boring: Multi-diameter bores with precise shoulder depths and concentricity between steps for complex housings and adapter plates.
• Taper Boring: Internal taper boring for Morse tapers, Jacobs tapers, and custom tapered bores for tool holding and mounting applications.
• Counter Boring & Spot Facing: Enlarging existing holes to specific depths for bolt heads, socket cap screws, and counterbore fasteners.
• Internal Grooving: Cutting internal grooves for circlips, O-rings, oil seals, and snap rings within bores.
• Bore Honing (if available): Fine surface finishing of bores for hydraulic cylinders, pneumatic cylinders, and precision bushings.
