CNC boring mills for precision machining operations of milling, boring, drilling, reaming and tapping on large workpieces

Primarily designed for high-performance boring and milling, our CNC table type boring and milling machines also excel at drilling, reaming, and plane milling operations. They are exceptionally suited for processing box-type parts, frame components, and molds where precise hole spacing is critical. A key advantage is the ability to complete multiple processes—milling, boring, drilling, reaming, and tapping—in a single workpiece clamping, significantly enhancing productivity. These machines offer sophisticated six-axis control with four-axis simultaneous linkage, enabling complex operations like circular interpolation and the machining of 3D curved surfaces.

Applications

This machine is widely used for the machining of box-type components, frame structures, and mold parts.

Features

Each axis is driven by its own dedicated servo motor, allowing for stepless speed regulation.

The main machine is equipped with a rotary table and features a cross-slide structure. It is composed of several major components including the bed, worktable, upper and lower saddles, column, a side-mounted horizontal spindle box, and a tailstock.

Under the control of the CNC system, arbitrary four-axis simultaneous linkage can be achieved, thereby satisfying the processing requirements for various workpieces.

The machine can be configured into different grades and specifications according to user requirements, by incorporating different CNC systems, achieving different precision levels, and selecting various rotary table size options.

Main Components

The CNC table type boring and milling machine primarily consists of the (machine) bed, column, headstock, saddle, transverse saddle, worktable, lubrication and cooling systems, and the electrical system.

Worktable The worktable's transverse movement along the saddle guideways constitutes the X-axis. The saddle's longitudinal movement along the bed guideways is the W-axis. The headstock's vertical movement along the column guideways is the Y-axis. The boring spindle's axial movement within the milling spindle is the Z-axis. The worktable's 360° rotation on the transverse slide is the B-axis. The sliding carriage, worktable, and other major components are made from high-quality castings. They undergo a secondary heat treatment (thermal aging) after rough machining to eliminate internal stress, prevent creep, and maintain long-term precision stability.

Machine Bed The integral machine bed is manufactured from high-quality castings, with an internal cavity featuring a rational arrangement of reinforcing ribs. It undergoes a secondary heat treatment after rough machining to eliminate internal stress, prevent creep, and ensure long-term precision stability.

Column The column is made from high-quality castings and employs a double-wall structure with internal reinforcing ribs. It also undergoes a secondary heat treatment after rough machining to eliminate internal stress, prevent creep, and maintain long-term precision stability.

Headstock The headstock is a box-shaped high-quality casting, with reinforcing ribs arranged on its inner walls. It undergoes a secondary heat treatment after rough machining to eliminate internal stress, prevent creep, and maintain long-term precision stability.

Main Drive System The main drive system utilizes an AC spindle servo motor. The main motor is directly connected to a reducer, and then, after reduction via an imported reduction gearbox, it drives the milling spindle's rotation through a synchronous toothed belt.
