HTS3000 Heavy-Duty CNC Horizontal Honing Machine

Overview

The HTS3000 heavy-duty CNC horizontal honing machine is an industrial-grade solution engineered to master the finishing of extra-long, large-diameter bores— a task where standard honing equipment falls short. Boasting a 3000mm (3-meter) work stroke, it delivers unparalleled precision, stability, and automation, ideal for manufacturing super-sized hydraulic cylinders, massive actuator tubes, and other critical long-bore components. Its rigid cast iron structure and advanced CNC controls turn complex long-bore honing into a reliable, repeatable, and highly efficient production process.

Core Features of HTS3000 heavy-duty CNC horizontal honing machine

1. 3-Meter Ultra-Long Honing Stroke

It offers a 3000mm single automated stroke, finishing bores up to 3 meters long in one setup. It eliminates manual repositioning or splicing, saving time and reducing human error in long-bore processing.

2. Ultra-Rigid Horizontal Bed Structure

Equipped with a massive, reinforced cast iron bed and carriage, the machine ensures superior stability and vibration dampening along the long axis. This design guarantees geometric accuracy throughout the entire 3-meter stroke for every workpiece.

3. Advanced Multi-Axis CNC Control System

Powered by high-precision CNC systems (e.g., Siemens), the machine controls the honing head’s X-axis (stroke), Z-axis (feed/expansion), and C-axis (spindle rotation). It supports complex cycle programming, ensuring absolute consistency in large-diameter bore finishing.

4. High-Torque Spindle & Servo Drive System

The machine features a high-torque spindle motor with a wide variable speed range (10-350rpm) and a robust servo-driven ball screw system. It delivers smooth, powerful, and precise movement for long-stroke honing operations.

5. Automated In-Process Sizing (Optional)

An integrated gauging system with automatic tool compensation is available for the machine. It achieves micron-level diameter accuracy without stopping the machine, boosting efficiency for mass production.

6. High-Capacity Coolant & Filtration System

The machine is fitted with a 500L high-flow coolant tank and paper-band/magnetic filtration. It effectively manages heat and removes swarf during long cycles, protecting tools and workpieces from damage.

7. Programmable Dwell & Reciprocation

The machine allows customizable stroke profiles, including variable speeds and end-stroke dwells. This optimizes surface finish and geometry for challenging materials in large-bore components.

8. Operator Safety & Ergonomic Design

Featuring a full-length safety enclosure with interlocked doors, centralized lubrication, and a pendant control station, the machine ensures safe and convenient operation in industrial environments.

Competitive Advantages of HTS3000 heavy-duty CNC horizontal honing machine

✅ Unmatched Extra-Long Part Capability

The machine solves the unique challenge of precision honing for super-long bores— a feat manual or short-stroke machines cannot achieve, making it a leader in heavy-industry finishing.

✅ Zero Geometric Errors

Its horizontal design and extreme rigidity eliminate deflection, ensuring exceptional bore straightness, roundness, and cylindricity across the full 3-meter length of the machine’s stroke.

✅ Dramatic Productivity Gains

Full automation of the long-stroke honing process with the machine cuts labor costs, eliminates human error, and boosts throughput compared to traditional honing methods.

✅ Superior Finish & Consistency

The machine delivers repeatable high-quality surface finishes (Ra, Rz) and exact tolerances. This is critical for sealing and performance in long hydraulic cylinders and actuator tubes.

✅ Lower Total Production Cost

Faster cycles, reduced skilled labor needs, minimal scrap, and extended diamond tool life (via optimal CNC parameters) lower the cost-per-part for long-bore work with the machine.

✅ Future-Proof Flexibility

The machine stores countless programs for different part lengths and diameters (within its φ20-φ630mm range), enabling quick changeovers for new projects.

✅ Industrial-Grade Durability

Built for continuous operation in demanding heavy-industry environments, the  machine ensures high uptime and a long service life, minimizing maintenance downtime.
