The multi-bit combination drilling machine is a highly efficient and specialized hole processing equipment. It can complete the drilling or tapping of multiple holes on a workpiece at one time through the simultaneous operation of multiple bits. It is widely used in batch production scenarios and significantly improves processing efficiency and accuracy.
I. Core Functions and Advantages
High efficiency : Compared with traditional single-axis drilling machines, multi-bit combined drilling machines can complete the processing of multiple holes in one feed, with efficiency increased by several times or even dozens of times.
High precision : It adopts fixed or multi-axis linkage design, combined with guide hole plates or numerical control systems, to ensure accurate hole spacing and good consistency.
Strong applicability : Supports processing of various materials such as metal, aluminum alloy, and plastic, and is especially suitable for standardized production in industries such as automotive parts, bathroom hardware, doors, Windows, and curtain walls.
High degree of automation : It can be combined with pneumatic, hydraulic or numerical control systems to achieve automatic feed, fast feed/working feed switching, reducing the labor intensity of workers.
Ⅱ. Main Types and Application Scenarios
| Type | Feature | Applicable scene |
| Adjustable multiple spindle drill | The number and spacing of the main shafts are adjustable, offering strong flexibility | Small-batch and multi-variety processing, such as molds, custom brackets, etc |
| Fixed multi-axis drilling machine | Customized according to the workpiece, with high precision and good stability | Mass production of single products, such as engine casings, wheels, etc |
| Nc multi-head drilling machine | It is equipped with a PLC or CNC control system and supports programming operation | Processing of parts with complex hole layout and high-precision requirements |
| Pneumatic/hydraulic multi-head drilling machine | The gas-liquid damping device is adopted, ensuring smooth feed | Drilling of aluminum profiles and long materials, such as processing of door and window and curtain wall profiles |
Ⅲ. Typical Technical Parameters (Taking Common Models as Examples)
Drilling diameter range : Φ3-13mm (some can reach Φ25mm)
Number of spindles : 2-12 heads (customizable upon request)
Main motor power : 1.5-11kW (depending on configuration)
Control mode : manual, semi-automatic or fully automatic control
Applicable materials : aluminum profiles, steel, cast iron, copper parts and other metal materials
Iv. Purchasing Suggestions
If it is used for the production of large quantities of standard parts , fixed or multi-station combined drilling machines should be given priority to ensure processing consistency.
If the hole spacing of the processed object changes significantly , it is recommended to choose an adjustable multi-spindle machine or a CNC model to enhance adaptability.
For the processing of aluminum profile doors and Windows , it is recommended to use horizontal combined drilling machines equipped with pneumatic feed and adjustable power heads, such as the HSLZ-513 type;
When emphasizing operational convenience, you can choose an intelligent model with touch screen control and self-diagnosis function for faults.
