Large Tube Honing Machine For Repair Works

Large Tube Honing Machine for Repair Works – Key Features & Specifications

▲ Servo-Controlled Honing Head Expansion & Tightening

Stable & Precise Pressure Control: Servo motor sets tightening/expanding pressure via torque, ensuring constant pressure during the honing process. Ideal for large tube honing for repair works, where consistent material removal is critical.

Automatic Inner Hole Inspection: Enables partial honing to enhance efficiency. In constant pressure mode, the torque display table digitally shows torque at each point, allowing operators to assess workpiece inner hole condition. For repair works, this allows targeted honing of damaged or uneven sections first, followed by thorough honing once the aperture is uniform. This improves efficiency and guarantees cylindricity and straightness – essential for large tube honing for repair works.

CNC Digital Control: All parameters are digitally set and read via the CNC system panel for precise adjustment.

▲ Cooling Method: External & Internal Oil Feeding Combined Mode

High-Pressure Flushing: Honing oil is fed internally through the honing bar, creating high pressure to effectively wash away honing debris – a key requirement for large tube honing for repair works to maintain surface integrity.

Enhanced Cooling for Long Tubes: Internal oil feeding overcomes the cooling limitations of external methods, especially for long workpieces (over 1.5m) . It ensures the honing head is constantly cooled and flushed, keeping stones sharp and drastically improving efficiency and quality – a major advantage in large tube honing for repair works.

Flexible Operation: External oil feeding can be selected for shorter workpieces.

Machine Brief

● Machine Functions & Application
This machine is specifically designed for large tube honing for repair works, as well as fine machining of cylindrical deep-hole parts like hydraulic and gas cylinders. It excels at both whole and partial honing, correcting taper, ellipse, and local aperture errors – common tasks in large tube honing for repair works. The servo-controlled honing head allows both constant pressure and constant volume infeed.

● Workpiece Clamping
Workpieces are placed on 3 sets of adjustable V-type brackets and locked with pipe clamp chains. This robust system ensures secure holding during demanding large tube honing for repair works.

● Machine Main Structure
Comprising: Machine bed, honing box, 3 workpiece brackets, 5 honing bar supports, rack and pinion, cooling system, Delta PLC control, and electric cabinet. Every component is built for the rigor of large tube honing for repair works.

● CNC Axes

Z1 Axis: Longitudinal infeed (reciprocating movement) of the honing box.

Z2 Axis: Controls tool expansion and contraction.
Both axes are servo-driven for precision, critical for accurate large tube honing for repair works.

● Machine Bed
High-rigidity cast iron bed, aged twice for stability. Features roller linear guides for high-speed reciprocation and a precision-ground rack. Designed to withstand the heavy loads of large tube honing for repair works.

● Honing Box
Drives the honing head with steplessly adjustable speed. The spindle, supported by robust bearings, handles high axial and radial forces – a necessity for large tube honing for repair works.

● Workpiece Bracket
3 sets of V-shaped brackets with anti-slip plates. The V-edges move synchronously via screw adjustment to center different diameters. Pipe chains manually lock the workpiece, ensuring stability during large tube honing for repair works.

● Honing Bar Support
5 sets (1 fixed, 4 movable) support the honing bar during processing and measurement, preventing deflection – vital for accuracy in large tube honing for repair works.
