What materials can an electric tapping machine tap?

1. Common carbon steel and alloy steel

Including commonly used mold steels such as Q235, 45# steel, A3 steel, S136, 718, and NAK80, enabling high-precision thread machining.

2. Stainless steel

Suitable for applications requiring corrosion resistance. The electric tapping machine, with its stable torque, can smoothly machine internal and external threads on stainless steel.

3. Copper and copper alloys

For soft metals such as brass and copper-zinc alloys, the machine's flexible tapping system prevents tap breakage and ensures a smooth surface finish.

4. Aluminum alloys

Lightweight metals are commonly used in aerospace and automotive parts processing. The stable speed of the electric drive allows it to maintain high precision even on aluminum.

5. Cast iron and ductile iron

With appropriate torque control, reliable tapping operations can be achieved on high-hardness cast iron materials.

How to choose the right electric tapping machine model for your factory?

1. Material and thread specification matching

Determine the required maximum torque range based on the hardness of the material being processed and the thread size. Excessive torque can easily cause the tap to break, while insufficient torque will result in incomplete thread formation. When selecting a model, refer to the machine's torque adjustment range and material compatibility table.

2. Power, Speed, and Machining Depth

Different models of electric tapping machines vary significantly in power (HP/kW) and speed (rpm). Large-diameter threads (such as M24 and above) require higher power and lower speeds to ensure cutting strength; fine threads (M5-M10) are suitable for high-speed mode. The power-speed ranges provided in the product catalog can be directly compared with process requirements.

3. Working Radius and Arm Length Design

The machine tool's working radius determines the maximum size of the workpiece that can be machined. If the workpiece diameter or machining depth is large, a model with a working radius of 1900mm or more should be selected; for workshops with limited space, a more compact arm length design can be considered.

4. Automation Functions and Ease of Operation

Modern Electric Tapping Machines are equipped with depth sensing, automatic lubrication, and programmable control panels, which can significantly improve production efficiency and reduce operating difficulty. When selecting a model, priority should be given to models with these intelligent features to meet the needs of "one-click tapping" and mass production.
