Vertical Honing Machine For Automative Parts

1. Main Functions of the Machine Tool
The 2MK2240 CNC vertical honing machine is specifically designed as a high-performance vertical honing machine for automotive parts, particularly suited for deep-hole applications. It is widely used for finishing hydraulic cylinders, spindle bores, engine cylinder liners, and cooling passages in various automotive components. As a reliable vertical honing machine for automotive parts, it consistently achieves bore size accuracy within IT7~IT9 and delivers inner surface roughness between Ra0.4 and 1.6μm. The machine supports both full-length and localized honing; during local honing, it effectively corrects taper, ovality, and local diameter deviations in the workpiece.

All major castings follow a box-type structural design, verified through finite element analysis and optimized to ensure proper mass distribution, high static and dynamic rigidity, and long-term precision stability. The castings are produced from high-strength cast iron using the resin sand process. After casting, they undergo normalizing to relieve internal stresses; a second normalizing cycle is performed after rough machining to eliminate both residual casting stresses and cutting-induced stresses, thereby guaranteeing excellent precision retention and thermal stability.

2. Overall Layout and Main Structural Components
The machine is arranged with its base section installed below floor level, while the workpiece upper end remains above ground for convenient operator measurement and setup. The layout adopts a fixed upper workpiece position and a vertically movable lower worktable.

Key assemblies include the base, worktable, spindle head, servo-controlled expansion system, column, coolant unit, and CNC control system. The primary cast structural parts are the base, worktable, spindle head, and column. This configuration ensures that the vertical honing machine for automotive parts delivers consistent cycle-to-cycle accuracy, and its servo tool expansion allows real-time diameter control-an essential feature for production environments where the vertical honing machine for automotive parts must handle varying bore sizes and material conditions with minimal operator intervention.

Workpiece table:

The work and the spindle box share a linear guide rail for reciprocating movement, and the worktable moves up and down to adapt to clamping workpieces of different lengths. The workbench moving system consists of servo motors, ball screw pairs, etc., to achieve up and down movement and servo clamping. The workbench is equipped with telescopic protection, which effectively protects the linear guide rail and ball screw pair and increases their service life.

The workbench is used to install fixed workpieces. The center of the workbench has a positioning hole that is coaxial with the height of the spindle box and is used to install tooling fixtures. This machine tool is equipped with a three-jaw self-centering chuck as standard. Special tooling fixtures are made by users themselves. The workbench has a T-slot for fixing workpieces or tooling fixtures.
