The difference between drilling machine and cnc machining center

Drilling and tapping machine and machining center are CNC machine tools, but they are different in function, application scope, structure and configuration, processing accuracy and speed, cost and maintenance.

1. Function and application range

Machining center: Machining center is a highly automated machine tool, integrating a variety of processing functions such as milling, drilling, tapping, etc., suitable for multi-process processing of complex parts, suitable for mass production and processing of complex parts.

Drilling and tapping centers: Drilling and tapping centers are primarily focused on machining functions such as drilling, milling, and tapping, and are often used in the machining of light and small metal parts, designed to show greater efficiency and accuracy in these specific functions.

2. Structure and configuration

Machining center: The machining center is usually equipped with a large tool library and automatic tool change system, which can realize the rapid switching of multiple tools, and may have three axes, four axes or even more than five axes.

Drilling and tapping center: The structure of the drilling and tapping center is relatively simple, usually focusing on high-speed drilling and tapping functions, and the tool library capacity is smaller, but the tool change speed is often faster.

3, processing accuracy and speed

Machining center: Due to its versatility, machining center has high requirements in machining accuracy and can achieve high-precision machining.

Drilling and tapping centers: Drilling and tapping centers are usually better than machining centers in drilling and tapping accuracy and speed, especially in the machining of light and small parts

4. Cost and maintenance

Machining centers: Due to their high degree of automation and versatility, the acquisition and maintenance costs of machining centers are usually higher.

Drilling and tapping centers: Drilling and tapping centers are relatively low cost and easier to maintain, making them suitable for smes or scenarios with high demand for specific machining functions.

5. Other differences

Volume: The volume of the drilling center is usually smaller than that of the machining center, because it mainly works with smaller workpieces.

Tool store tool change system: the drilling and attacking center generally uses the sun type tool store, and the machining center generally uses the tool arm type tool store.

Processing object: The drilling and tapping center mainly processes small aluminum parts, such as mobile phone shells, etc., while the processing center is mainly used in the field of mold processing, mainly processing steel materials.

Cutting force: The drilling and tapping center does not have a large cutting force, suitable for processing aluminum alloy and other soft metal materials, and the machining center is good at large cutting, suitable for the processing of hard metal materials.

In summary, the choice of drilling machine or machining center depends on the specific production needs, cost budget and processing objectives. The machining center is the ideal choice for enterprises that require multi-functional, high-precision and complex parts processing. For companies that focus on specific processing functions and pursue high efficiency and cost effectiveness, drilling and tapping centers are more suitable.
