The difference between drilling and tapping machines and machining centers

The difference between drilling and tapping machines and machining centers. Both drilling and tapping machines and machining centers are CNC machine tools, but they differ in functions, application scope, structure and configuration, machining accuracy and speed, cost and maintenance.

  1. Function and application scope

Machining center: A machining center is a highly automated machine tool that integrates multiple machining functions such as milling, drilling, and tapping. It is suitable for multi-process machining of complex parts and suitable for mass production and machining of complex parts.

Drilling and tapping center: The drilling and tapping center mainly focuses on machining functions such as drilling, milling and tapping. It is usually used for the machining of light and small metal parts. The design makes it show higher efficiency and accuracy in these specific functions.

  1. Structure and configuration

Machining center: The machining center is usually equipped with a large tool magazine and an automatic tool changing system, which can realize the rapid switching of multiple tools and may have the linkage capability of three, four or even five axes.

Drilling and tapping center: The structure of the drilling and tapping center is relatively simple. It usually focuses on high-speed drilling and tapping functions. The tool magazine capacity is small, but the tool change speed is often faster.

  1. Processing accuracy and speed

Processing center: Due to its versatility, the processing center has high requirements for processing accuracy and can achieve high-precision processing.

Drilling and tapping center: The drilling and tapping center is usually better than the machining center in terms of drilling and tapping accuracy and speed, especially in the processing of light and small parts.

  1. Cost and maintenance

Processing center: Due to its high degree of automation and versatility, the purchase cost and maintenance cost of the machining center are usually high.

Drilling and tapping center: The cost of drilling and tapping centers is relatively low, and maintenance is also simpler. It is suitable for small and medium-sized enterprises or scenarios with high demand for specific processing functions.

  1. Other differences

Volume: The volume of the drilling and tapping center is usually smaller than that of the machining center because it mainly processes smaller workpieces.

Tool magazine tool changing system: The drilling and tapping center generally uses a sun-type tool magazine, while the machining center generally uses a tool arm-type tool magazine.

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

Cutting force: Drilling and tapping centers do not have large cutting force and are suitable for processing soft metal materials such as aluminum alloys, while machining centers are good at large cutting and are suitable for processing hard metal materials.

In summary, choosing a drilling and tapping machine or a machining center depends on specific production needs, cost budgets, and processing goals. For companies that require multi-functional, high-precision, and complex parts processing, machining centers are an ideal choice; while for companies that focus on specific processing functions and pursue high efficiency and cost-effectiveness, drilling and tapping centers are more suitable.
