Key Features Of CNC Vertical Honing Machine
This Vertical Honing Machine is designed to process a wide range of bore types, including through holes, blind holes, intermittent holes, stepped bores, and other complex internal geometries. It supports stable bore finishing across different component designs and machining conditions. The machine helps achieve reliable geometry correction, improved surface finish, and consistent dimensional control for precision internal hole processing.
The MB Series Vertical Honing Machine is suitable for honing multiple workpiece materials, including cast iron, quenched steel, aluminum alloy, titanium alloy, stainless steel, and ceramics. This wide material compatibility allows the machine to meet different machining requirements across a variety of applications. It provides greater flexibility in component processing and process planning when working with different material properties and bore finishing standards.
Equipped with an advanced CNC control system, this Vertical Honing Machine enables precise parameter setting and stable process control for different workpieces and machining requirements. The integrated USB interface supports convenient program transfer between the machine and a computer, making data management and program backup more efficient. This feature also helps improve repeatability and simplify operation during different honing tasks.
The Vertical Honing Machine includes both manual and automatic tool wear compensation functions to reduce the impact of abrasive wear during operation. This helps maintain stable bore size, surface finish, and machining accuracy throughout extended processing cycles. The compensation function also improves process consistency and reduces the need for frequent manual correction.
This Vertical Honing Machine combines a spindle speed range of 100–2000 rpm with a reciprocating speed of up to 40 m/min, delivering strong performance in both efficiency and precision. The servo motor and ball screw system provide 0.1 μm resolution, allowing accurate stroke and feed control during the honing process. This helps improve machining efficiency, shorten cycle times, and maintain consistent finishing quality.
To ensure stable operation, the Vertical Honing Machine is equipped with a complete support system that includes cooling, filtration, and automatic lubrication. The magnetic separator, paper tape filter, and oil cooler help maintain honing oil cleanliness and temperature stability, with filtration precision up to ≤ 25 μm. At the same time, the automatic lubrication system reduces mechanical wear, supports long-term precision, and improves overall machine reliability.
