CNC Deep Hole Pull Boring Machine

CNC Pull Boring Machine – High-Precision Deep Hole Boring Solution

 

cNC pull boring machine Overview:

The LTK2230 CNC Pull Boring Machine is a high-performance deep hole boring system designed for precision machining of large workpieces. It supports pull boring operations on components with hole diameters from Φ40mm to Φ300mm and workpiece lengths up to 8000mm. This machine is ideal for industries requiring high rigidity, stable cutting performance, and automated control, such as hydraulic cylinder manufacturing, heavy machinery, and automotive parts production.

CNC Pull boring Machine Structure & Features :

1. CNC pull boring machine Working Principle

Cutting oil is supplied through the oil feeder and the gap between the boring bar and the workpiece bore. Chips are flushed into a chip conveyor for efficient removal.

 

2. Main Components of cNC pull boring machine

Heavy-duty cast iron bed (resin sand casting, normalized, double V-ribbed structure)

Tailstock with hydraulic drive and cone plate clamping

Oil feeder with servo-driven axial movement and tool support sleeve

Boring headstock (rotary drive via belt and gear train)

Tool support bracket with automatic return mechanism

Workpiece support stands and center clamps

Automatic lubrication system with low-level alarm

 

3. Workpiece Clamping Process (Fully Automated)

Workpiece support stand rises automatically

Workpiece is placed on the stand

Tailstock and oil feeder move axially to clamp the workpiece with cone plates

Center clamps engage automatically

Support stand retracts

 

4. CNC & Drive System:

Controller: Siemens 828D

Z-axis (feeding): Servo motor + gear-rack drive

X-axis (clamping): Servo motor + gear-rack drive

Boring headstock: Manual 3-speed gearbox with stepless regulation

 

Standard Accessories :

Quality & Manufacturing Highlights:

1. Cast iron components undergo two-stage aging treatment to eliminate internal stress

2. Induction-hardened guideways for high wear resistance

3. Precision-ground gears with high-frequency quenching for strength and durability

4. Integrated oil return channels and splash guards for clean operation
