CNC Deep Hole Vertical Honing Machine

Automotive Parts Vertical Honing Machine – 2MK2210 CNC Vertical Honing Machine

1. Main Functions
This automotive parts vertical honing machine is designed for high-precision machining of deep-hole components such as hydraulic cylinders, spindle bores, cylinder bores, and cooling holes. It achieves dimensional accuracy of IT7–IT9 and surface roughness of Ra0.2–Ra1.6 μm.
The automotive parts vertical honing machine supports both integral and local honing, enabling correction of taper, ovality, and localized bore errors.

2. Structural Design & Castings
All castings utilize a box-type structure optimized via finite element analysis, ensuring high rigidity, reasonable mass, and precision stability.
Castings are produced from high-strength cast iron using resin sand molding, followed by normalization before and after rough machining to eliminate internal and machining-induced stresses-critical for the long-term accuracy of this automotive parts vertical honing machine.

3. Machine Layout & Key Components
The automotive parts vertical honing machine consists of a base, worktable, spindle box, servo tool expansion system, column, cooling system, and CNC system. Main castings include the base, spindle box, and column.

Base & Worktable
A movable worktable (front/back direction) is mounted on the base, driven by a servo motor and ball screw pair, with steel telescopic covers protecting the guides and screw. The worktable center features a locating hole coaxial with the spindle for tooling, and comes standard with a three-jaw self-centering chuck. T-slots parallel to movement direction allow flexible workpiece or fixture mounting.

Spindle Box & Servo Tool Expansion System
The spindle box provides rotational power via a servo motor and reducer. The servo tool expansion system-comprising a servo motor, precision planetary reducer, and ball screw-controls honing tool expansion and contraction. This automotive parts vertical honing machine enables both constant-pressure and quantitative feed control.

Column

Fixed to the base, the column houses linear guides for spindle box reciprocation, driven by a servo motor, reducer, and ball screw pair for smooth, high-efficiency, high-precision motion. Organ-type telescopic covers protect the guides and screw.

Cooling System
An above-ground tank system with a cooling pump, magnetic roller filter, and paper bag filter supplies external oil-jet lubrication and cooling, effectively flushing chips from the cutting area.

Machine Protection
The automotive parts vertical honing machine features a semi-enclosed structure, offering splash protection and a clean, modern appearance.

Throughout the design and construction, this automotive parts vertical honing machine emphasizes rigidity, precision stability, and operational flexibility, making it a specialized solution for high-quality bore finishing in automotive and hydraulic applications.
