Automatic Longitudinal Feed Cylinder Boring Machine with Stepless Speed Regulation and Optional Cylinder Block Surface Milling for Engine Boring Equipment

The T8018C is a production-oriented cylinder boring machine with automatic longitudinal worktable feed, designed for medium and heavy engine repair workshops and engine remanufacturing plants. Compared with manual feed models, it adopts a stepless speed regulation automatic feed mechanism, with stable feed speed and uniform cutting amount, which greatly reduces the labor intensity of operators and ensures the consistency of batch processing accuracy.

This model is mainly oriented to medium-duty diesel engines, construction machinery engines, and commercial vehicle engines. It supports an optional cylinder block surface milling function and can be used for boring cylinder blocks, cylinder liners, and various sleeve parts. It is standard equipment for medium-sized engine remanufacturing production lines and large-scale commercial vehicle repair bases.

• Automatic longitudinal feed system: Stepless speed regulation automatic feed, stable cutting speed, uniform boring allowance, good batch consistency, and greatly reduced labor intensity of workers.
• High-rigidity long-stroke guide rail: Reinforced column guide rail, stable accuracy during long-stroke boring, suitable for medium and heavy engine cylinder blocks.
• Wide process adaptability: 8-speed spindle + stepless feed, which can be matched according to different materials, bore diameters, and process requirements, with strong process adaptability.
• Optional integrated milling function: Optional cylinder top surface milling unit; one clamping completes boring and milling, reducing secondary positioning error and improving processing efficiency.
• Stroke limit protection device: Equipped with upper and lower stroke limit switches, which automatically stop when reaching the set position — safe and reliable, suitable for long-time continuous operation.

1. Heavy-Duty Boring Spindle Unit
   High-rigidity cast iron column with precision grinding guide rail. 2.2 kW high-power spindle motor, strong cutting ability, suitable for continuous boring of medium and heavy engines.
2. Automatic Longitudinal Feed Worktable
   Longitudinal automatic feed mechanism with stepless speed regulation, stable feed speed and uniform cutting. The transverse is manually adjusted for centering. Equipped with stroke limit device for safe production.
3. Optional Milling Compound Unit
   Side-mounted milling head unit, which can mill the top surface of the cylinder block at the same time as boring. Compound processing improves production efficiency, which is very suitable for remanufacturing batch production.
4. Automatic Control Operation Panel
   Integrates spindle control, feed speed regulation, stroke setting, and lubrication control. The operation interface is clear, and workers can quickly master the automatic production mode.
