A semi-automatic circular metal saw is an industrial device specifically designed for cutting metal materials such as steel plates, aluminum plates, pipes, and profiles. It features a semi-automatic workflow—the rotation and feed of the saw blade are driven by a motor, hydraulic, or pneumatic system, while feeding, clamping, and angle adjustment still require manual or semi-automatic operator control.

Main Components and Working Principle:

Circular Saw Blade: A high-speed rotating metal circular saw blade, often equipped with a coolant circulation system, which maintains blade life and achieves a clean cut with virtually no burrs and low noise during cutting.
Drive and Transmission: Employs a cycloidal pinwheel, bevel gear, or gear transmission mechanism, providing stable speed and high sawing efficiency.
Clamping and Feed: Double-sided, two-way clamps or hydraulic/pneumatic quick-clamping devices ensure secure material fixation; the feed speed is adjustable, and some models feature automatic feeding.
Angle Adjustment: The saw head can rotate left and right (commonly 0°–45°), supporting beveling or milling. Precise angle adjustment is suitable for special processing needs such as pipe joints and beveling. Cooling and chip removal: The circulating cooling pump works in conjunction with the mist lubrication system to reduce cutting heat and collect metal chips, keeping the working environment clean.

The Automatic Circular Metal Saw is a CNC machining equipment specifically designed for cutting metal materials such as steel bars, round tubes, square tubes, and angle steel. It uses a high-speed rotating circular saw blade to quickly and precisely cut metal, and is equipped with a complete automation system, enabling fully unmanned operation. Its main features include:

Automatic Feeding and Positioning
Using a hydraulic or servo-driven feeding device, the material is automatically fed into the cutting area and precisely positioned.
Automatic clamping and separation of workpieces allow for continuous cutting after a single feed, eliminating the need for manual clamping.

CNC Control System
Based on a PLC/HMI or CNC control panel, the user interface is typically a large touchscreen. Users only need to input parameters such as material specifications, cutting length, and cutting speed; the system automatically adjusts parameters such as saw blade speed, feed rate, and cutting depth.
Supports programmed batch processing, suitable for mass production.

High-Efficiency Cutting Performance
The saw blade speed is adjustable from 50–180 rpm (or even higher), and with a high-power dual-speed motor or frequency converter drive, high-speed cutting is achieved with a cutting accuracy of ±0.05mm.
An oil mist or water mist cooling system ensures virtually burr-free cutting, extending saw blade life and reducing post-processing costs.

Safety and Protection
A fully enclosed protective structure, blade vibration damping technology, and automatic alarm and emergency stop devices ensure safe operation and automatically shut down the machine in case of abnormalities.
|An automatic chip conveying system (spiral or chain type) removes metal chips in real time, keeping the work area clean and reducing maintenance frequency.

Wide Range of Applications
It can cut metal materials such as round bars, round tubes, square tubes, and angle steel with diameters of 8mm–230mm (some models are larger), and can also be used for non-ferrous metals such as stainless steel and aluminum alloys.
Commonly used in the processing of metal parts in the automotive, mold, construction, and shipbuilding industries.
