OverviewThe T8018A is a precision fine boring machine for cylinder blocks, engineered to deliver high roundness and bore finish accuracy for inner bores. Its 30–180 mm diameter range and 450 mm maximum boring depth accommodate a wide variety of gasoline and diesel engine blocks used in automotive, marine and generator repair applications.
Main Capabilities- Processing diameter: 30–180 mm
- Maximum boring depth: 450 mm
- Spindle feed (selectable): 0.05 / 0.10 / 0.20 mm/rev
- Spindle rotational speed: infinitely variable
Key Features- Wide diameter range (30–180 mm): Supports compact and large engine blocks including inline and V configurations.
- Fine incremental feed control: Three selectable feeds for precision finish boring.
- Heavy-duty base and spindle assembly: Minimizes vibration and maintains alignment during deep boring operations.
- Quick-adjust boring head: Reduces setup time between different bore sizes.
- Depth-stop and dial indicators: Ensure consistent multi-cylinder alignment and repeatable finish depth.
Recommended Configurations- Centering tool kit for precise concentricity
- Magnetic-base dial gauge to measure taper, roundness and axial deviation
- Adjustable workholding jigs for quick change between inline and V-type blocks
- Surface finish hone set for final polishing to control oil retention and piston travel
- Coolant spray or chip blower to keep the cutting area clear
Application Case- Client: Automotive rebuild workshop (example)
- Use case: Reboring 4-cylinder diesel engine blocks to oversize pistons
- Setup: T8018A with precision centering base and honing attachment
- Results: Bore diameter deviation < ±0.01 mm; Surface finish Ra 0.8–1.2 µm; piston-ready bores
- Feedback: Reliable finish often eliminating need for secondary honing
