New Designed Vertical Honing Machine

                                                               Vertical CNC honing machine

Machine Overview

This machine tool features a rational and robust structural layout. All primary motions-including spindle rotation, reciprocating movement, and tool expansion-are driven by servo motors combined with high-precision transmission systems, ensuring excellent rigidity, stability, and machining accuracy.

The machine is equipped with a complete cooling, filtration, and protection system and is centrally controlled by a reliable CNC system. It is specifically designed for high-precision honing of large, deep-hole components.

1. Overall Structure

The machine mainly consists of the following key components: base, worktable, spindle box, servo-controlled expanding tool system, column, guide frame, cooling system, and CNC control system.

Major structural parts-including the base, worktable, spindle box, and column-are manufactured from high-strength cast iron, providing superior rigidity, structural stability, and vibration damping.

2. Main Components Description

2.1 Base and Worktable

The worktable is driven by a servo system and allows smooth forward and backward movement, enabling convenient loading and clamping of workpieces.

The table surface is equipped with a standard three-jaw chuck, T-slots, and a central positioning hole, allowing flexible fixture installation and secure workpiece positioning. All moving components are protected by steel covers to effectively safeguard guideways and ball screws.

2.2 Spindle and Expanding Tool System

The spindle and expanding tool system are fully servo-driven, providing precise control over spindle rotation and tool expansion. The system ensures high positioning accuracy, stable operation, and reliable expansion performance, fully meeting the requirements of high-precision honing applications.

2.3 Column and Reciprocating System

The column is rigidly mounted on the base, and its guideways support the reciprocating motion of the spindle box. This motion is driven by a servo motor and transmitted through high-precision ball screws. An accordion-type protective cover is installed to protect the transmission components and maintain long-term machining accuracy.

---

2.4 Guide Frame

The guide frame shares the same guide rail as the spindle box. It is designed to position and clamp the upper end of long workpieces while simultaneously guiding and supporting the honing tool, thereby ensuring machining stability and precision.

---

2.5 Cooling System

The machine adopts an external coolant injection method combined with an above-ground coolant tank. A multi-stage filtration system, consisting of a magnetic roller and paper filter, ensures high coolant cleanliness, effectively providing lubrication, cooling, and efficient chip removal during the honing process.

---

2.6 Protection and CNC Control System

The machine is equipped with a semi-enclosed protective structure, which effectively prevents coolant splashing while maintaining a clean and professional appearance.

An independent CNC electrical cabinet features internal cooling, dust protection, and temperature control, ensuring stable, reliable, and long-term operation of the control system.
