350CNC CNC Pipe and Tube Cutting Machine

The 350CNC CNC Pipe and Tube Cutting Machine with Hydraulic Cylinder Automatic Feed is an industrial metal cutting machine designed for efficient and repeatable processing of pipes, tubes, angle steel, rectangular profiles, and solid metal rods. The 350CNC configuration combines hydraulic feeding, horizontal clamping, controlled cutting-head movement, and a circular saw blade system to provide a practical solution for manufacturers that require accurate and consistent metal cutting.

According to the supplied specifications, the machine provides a maximum feed length of 1000 mm and feeding and cutting accuracy of ±0.1 mm. It supports saw blade diameters from 250 to 450 mm, with a 32 mm blade bore diameter and a specified pin-hole configuration. The main motor is rated at 4.5/5.5 kW, while spindle speed is specified at 60/120 RPM.

The actual cutting performance depends on material type, workpiece dimensions, blade selection, cutting parameters, and operating conditions.

CNC Pipe and Tube Cutting

The 350CNC is designed for controlled cutting of different metal profiles. The supplied cutting capacity includes a 130 mm round pipe, 110 × 110 mm square tube, 110 × 110 mm angle steel, 150 × 90 mm rectangular tube, 60 mm solid round rod, and 50 × 50 mm square solid rod.

These capacities provide flexibility for common metal fabrication applications. Customers should confirm the exact material grade and required cutting conditions before selecting the machine because stainless steel, carbon steel, alloy steel, aluminum, and other metals have different cutting characteristics.

The machine can be used for preparing workpieces for welding, machining, assembly, structural fabrication, and general metal manufacturing.

Hydraulic Cylinder Automatic Feed

One of the key features of the 350CNC is its hydraulic cylinder feeding system. The hydraulic cylinder moves the material through the feeding process, helping provide controlled positioning before each cutting cycle.

The maximum specified feed length is 1000 mm. Feed length can be adjusted by modifying the position of the stopper.

Hydraulic feeding can provide a stable solution for repeated production because the workpiece can be positioned according to a defined feeding distance rather than relying entirely on manual measurement.

For high-volume production, consistent feeding can help reduce repetitive operator work and improve production standardization.

Horizontal Clamping System

The machine uses a horizontal clamping method to secure the workpiece during cutting. Proper clamping is essential for achieving stable cutting performance and maintaining dimensional consistency.

The workpiece should be positioned correctly before the cutting cycle begins. Stable clamping can help reduce unwanted movement and vibration during saw blade engagement.

Different workpiece shapes may require different clamping considerations. Round pipes, square tubes, rectangular tubes, angle steel, and solid rods do not always behave identically during cutting, so the workholding setup should be matched to the material profile.

These figures should be treated as the specified machine capacities under applicable operating conditions. Actual cutting capability can vary according to material, blade type, workpiece geometry, and cutting parameters.

Circular Saw Blade System

The 350CNC uses a circular saw blade with a specified diameter range of 250–450 mm. The blade bore diameter is 32 mm, and the supplied pin-hole specification is 2 × Ø11 × 63 mm PCD.

Selecting the correct saw blade is important for cutting quality, blade life, and production efficiency. Tooth geometry, blade material, tooth pitch, workpiece material, and cross-sectional shape should all be considered.

A blade suitable for carbon steel may not provide the same results when used for stainless steel or non-ferrous materials. Buyers should provide their material and workpiece requirements when confirming the blade configuration.

Motor and Spindle System

The main motor specification is 4.5/5.5 kW, with a spindle speed of 60/120 RPM. A separate 40 W cooling motor is specified for the cooling system.

The cooling system can help manage heat generated during the cutting process. Proper cooling and lubrication, where applicable, can contribute to stable cutting performance and help extend blade service life.

The machine's cutting-head drive uses a turbine worm drive, providing controlled mechanical movement of the cutting head during operation.

Precision Metal Cutting

The supplied specifications indicate ±0.1 mm feeding accuracy and ±0.1 mm cutting accuracy.

In actual production, achievable results depend on material characteristics, blade condition, workpiece clamping, machine alignment, feeding setup, cutting parameters, and operator procedures. The stated accuracy should therefore be considered a machine specification rather than a guarantee that every material and workpiece will automatically achieve the same finished tolerance.

For applications with strict dimensional requirements, customers should conduct testing with representative materials and workpieces.

Applications

The 350CNC CNC pipe and tube cutting machine can be used in a variety of manufacturing and fabrication environments, including:

Steel fabrication
Metalworking workshops
Pipe processing
Tube manufacturing
Machinery manufacturing
Agricultural machinery
Automotive components
Construction equipment
Structural metal fabrication
Industrial equipment production
Welding preparation
General machine shops

The machine is particularly useful where repeated straight cuts are required from standard metal stock.

Automatic Cutting Workflow

A typical cutting process begins with loading the pipe, tube, profile, or solid rod into the machine. The workpiece is then positioned using the hydraulic feeding system and secured by the horizontal clamping mechanism.

After the required position is established, the cutting head moves through the cutting cycle. Once the cut is completed, the system can prepare for the next feed and cutting operation according to the machine's control configuration.

This workflow helps reduce manual measuring and positioning for repetitive production.

Automatic operation should not be interpreted as completely unmanned production. Loading, unloading, blade inspection, quality checking, maintenance, and other tasks may still require operator involvement.

Industrial Production Efficiency

For manufacturers processing multiple pieces of the same material and length, automatic feeding can make the production workflow more consistent. The hydraulic cylinder feeding method can reduce repetitive manual positioning and support standardized cutting cycles.

Production output depends on workpiece dimensions, material, cutting length, blade selection, cutting parameters, loading and unloading time, and operator workflow.

The machine can be used as a standalone cutting system or incorporated into a broader fabrication process.

Installation and Maintenance

Before installation, the machine should be positioned on a suitable foundation or stable working area according to the manufacturer's requirements. Adequate space should be provided around the machine for material loading, unloading, blade replacement, inspection, and maintenance.

Routine maintenance should include checking the saw blade, hydraulic components, feeding mechanism, clamping system, cooling system, drive components, electrical connections, and machine alignment.

Metal chips should be cleaned regularly from the work area. Worn blades and other consumable components should be replaced according to their actual condition and the manufacturer's recommendations.

Operators should use appropriate protective equipment and follow safe operating procedures when working with rotating saw blades, hydraulic systems, metal workpieces, and cutting chips.

OEM and B2B Supply

For machinery distributors, steel-processing companies, metal fabrication workshops, and industrial manufacturers, the 350CNC can be supplied as a practical pipe and tube cutting solution.

OEM and ODM requirements can be discussed for qualified projects, including machine configuration, branding, packaging, documentation, electrical requirements, tooling, and other application-specific requirements.

Customers are encouraged to provide the material type, workpiece dimensions, required cutting length, production volume, and accuracy requirements so the machine configuration can be properly evaluated.
