T7220C High Precision Vertical Cylinder Boring and Milling Machine

T7220C High Precision Vertical Cylinder Boring and Milling Machine

The T7220C is a heavy-duty, multifunctional vertical cylinder boring and milling machine designed primarily for professional engine rebuilding, automotive workshops, and fleet maintenance centers. This machine is expertly engineered to perform two critical restoration tasks on a single platform: high-precision reboring of internal cylinder walls and smooth surface milling of engine block deck surfaces. It effectively corrects block warping, cylinder tapering, and ovality to achieve factory-standard geometries.

Built with an ultra-rigid cast-iron structure and an advanced mechanical drive layout, the T7220C ensures vibration-free performance and exceptional geometric accuracy. Featuring electronic variable spindle speeds and a precise longitudinal/cross worktable feed system, it provides technicians with effortless parameter adjustments to machine a wide range of passenger car and commercial truck engine blocks with premium micro-finish results.

• Dual Boring & Milling Functionality: Seamlessly switch between cylinder inner-hole boring and block deck surface milling, saving workshop space and equipment investment.

• Heavy-Duty Cast-Iron Rigidity: Constructed with a massive, high-stiffness structural frame that eliminates harmonic vibrations during deep roughing cuts.

• Infinitely Variable Spindle Speed: Equipped with electronic speed regulation, allowing operators to match perfect cutting speeds according to varying bore sizes and materials.

• Precision Multi-Axis Worktable: Features smooth longitudinal and cross table movements with accurate scale positioning, ensuring perfect alignment of multi-cylinder blocks.

• Rapid & Fine Feed Mechanics: Offers automated vertical fast-travel and precision micro-feed mechanisms, drastically lowering setup cycle times and reducing human error.

• Versatile Tool Outfitting: Comes with specialized boring heads, measuring devices, and milling cutters suitable for standard automobiles up to heavy commercial trucks.
