Introduction to Metal Circular Saw Machine Models

A metal circular saw machine is a high-efficiency, high-precision metal cutting and blanking equipment widely used for cutting metal materials like sectional steel, pipes, and bars. There are numerous models, and their naming conventions and meanings vary significantly depending on the classification method (e.g., structure, control mode, feeding method).

Below, I will introduce the common models and characteristics of metal circular saws based on several main classifications, listing some models from mainstream brands in the market for reference.

1. Classification by Structure (The most common method)

1. Horizontal Metal Circular Saw Machines

This is the most common type. The saw blade axis is parallel to the worktable, and the material is placed horizontally for cutting.

• Characteristics: Stable structure, easy operation, suitable for cutting long and heavy materials. Easy chip removal and relatively simple maintenance.

• Common Model Prefixes/Representations:

  • G: Might represent the first letter of the Chinese words for “Cutting” or “Saw”.

  • H: Might represent the first letter of the Chinese words for “Horizontal”.

  • S: Sometimes represents “Saw” or “Swing” (for pivot feed).

  • MJ: Common in some brands, representing “Metal Circular Saw”.

• Example Model:

  • MJ-320A: Indicates a horizontal metal circular saw with a saw blade diameter of 320mm. The ‘A’ might denote an improved or basic version.

2. Vertical Metal Circular Saw Machines

The saw blade axis is perpendicular to the worktable, and the material is usually clamped vertically.

• Characteristics: Small footprint, suitable for cutting short materials, plates, or multiple pieces simultaneously. Some models are easy to integrate into automated production lines.

• Common Model Prefixes/Representations:

  • VL or L: Represents “Vertical” or the Chinese word for “Vertical”.

  • V: Represents “Vertical”.

• Example Model:

  • VL-400: Indicates a vertical metal circular saw with a saw blade diameter of 400mm.

2. Classification by Control Mode and Automation Level

1. Manual/Semi-Automatic Metal Circular Saw Machines

• Manual Type: Feeding, clamping, cutting, and retraction are all performed manually. Less common now, mainly used for maintenance or small workshops.

• Semi-Automatic Type: The most common type. Manual feeding, but after pressing the start button, the machine automatically completes clamping, cutting, blade lifting, and unclamping.

• Model Characteristics: Models usually don’t have special letters for manual/semi-automatic; they are often basic models.

2. Fully Automatic Metal Circular Saw Machines

Integrate automatic feeding mechanisms, sizing systems, finished product collection devices, etc., enabling “one-button” automated production.

• Characteristics: Extremely high efficiency, high sizing accuracy, low labor intensity, suitable for mass production.

• Common Model Prefixes/Representations:

  • NC: Numerical Control, usually refers to automatic models controlled by PLC and touchscreen.

  • CNC: Computer Numerical Control, more powerful functions, can store multiple processing programs for more complex sizing and cutting management.

  • A: Adding “A” after the basic model number, e.g., MJ-320A, might indicate an automatic or upgraded version (requires checking the manufacturer’s definition).

  • Auto: Directly uses the English word “Automatic”.

• Example Models:

  • MJ-315NC: Indicates a numerical control horizontal metal circular saw with a saw blade diameter of 315mm.

  • H-450CNC: Indicates a CNC horizontal metal circular saw with a saw blade diameter of 450mm.

3. Classification by Feeding Method

1. Pivot Feed (Four-bar linkage)

The saw head assembly pivots around a fulcrum, swinging down like a pendulum to cut. This is the mainstream feeding method.

• Characteristics: Stable cutting, low impact, long saw blade life.

• Model Representation: Most horizontal circular saws use this structure; the model may not have a special identifier.

2. Slide Feed (Linear Feed)

The saw head assembly moves back and forth on linear guides for cutting.

• Characteristics: Good rigidity, suitable for cutting large-diameter solid bars, but the structure is relatively complex.

• Model Representation: Models sometimes include identifiers like “G” (from Chinese for “Slide”) or “Slider“.

4. Example Models from Mainstream Brands

Note: Naming conventions differ greatly among manufacturers. The following are just examples; specific parameters require consulting the manufacturer’s catalog.

How to Choose the Right Model Metal Circular Saw Machines?

When selecting a metal circular saw, don’t just look at the model number. Base your decision on the following key parameters and your specific needs:

1. Material to Cut: Steel, aluminum, stainless steel, or non-ferrous metals? The material’s hardness and shape (pipes, bars, profiles) determine the required machine power and rigidity.

2. Cutting Diameter/Range: What is the maximum outer diameter and profile size of the material you need to cut? This determines the required saw blade diameter and model.

3. Cutting Accuracy and Cut Surface Quality Requirements: How strict are the requirements for length tolerance, cut squareness, and smoothness? High precision requires choosing a CNC cold saw.

4. Production Efficiency Requirements: Is it small-batch or mass production? The latter must consider fully automatic models with feeding systems.

5. Budget: Imported brands (German, Italian, Japanese) offer top quality but are expensive; Taiwanese brands offer excellent cost-performance; Mainland Chinese brands are the most competitive in price, but quality and service require careful evaluation.

Summary Recommendation: When consulting manufacturers, don’t just say “I need a metal circular saw model.” Instead, provide your specific requirements (as listed above). The best approach is to contact several reputable suppliers directly, provide them with your samples or detailed requirements, and let them recommend suitable models and arrange test cuts. This is the most reliable selection method.
