In the mechanical processing workshop, a versatile machine is quietly revolutionizing the traditional processing methods - the drilling tapping machine. Through the 360° freely rotating arm and the multi-functional spindle, it enables the completion of processes such as drilling, tapping, and reaming on large workpieces with a single setup.
A drilling tapping machine is a type of machine that integrates multiple functions such as drilling, tapping (threading), and chamfering. This machine combines the flexibility of a traditional swivel drilling machine with the efficiency of a tapping machine, and is widely used in the field of mechanical processing. This article will mainly analyze the core features and technologies of the drilling tapping machine.
I. Core Positioning and Structural Characteristics of the Integrated Drilling Tapping Machine

1.Rocker arm design
Double-column structure:
The outer column is fitted onto the inner column. The rocker arm rotates around the inner column through a bearing (with a 360° rotation capability), significantly reducing the operational burden and enhancing stability.
Multi-directional adjustment:
The rocker arm can move up and down along the outer column (for example: for model 16C6-1, the rotation range can reach 360°), enabling it to accommodate the processing of workpieces of different heights and positions.
Compatibility of heavy-duty workpieces:
When dealing with the situation where large workpieces need to be fixed on the ground or the base, there is no need to use a special workbench. The drilling tapping machine can be placed on a special suction cup for operation.
2.Power and Transmission
Hydraulic/servo hybrid drive: Some high-end models adopt a hydraulic motor chain drive to achieve the rotation assistance of the rocker arm, supporting manual/automatic switching to solve the problem of strenuous operation for large rocker arms.
Spindle separation control: The main motor drives the drilling/tapping process, while an independent lifting motor adjusts the height of the swivel arm to avoid interference during movement.
II. Core Functions and Technical Advantages of the Integrated Drilling Tapping Machine

1.Multifunctional integrated processing:
Integrated drilling + tapping + chamfering: The main shaft supports forward and reverse rotation, and is compatible with the automatic feed function, enabling direct tapping after drilling without the need to change equipment.
2.Efficiency and Accuracy Assurance:
Automatic feed and pre-selected speed variation: The hydraulic pre-selection transmission machine shortens the auxiliary time, while the mechanical/electrical dual-safety feed system prevents incorrect operation.
3.The all-round helper of the maintenance workshop:
In the field of equipment maintenance, manual cranks can quickly locate the specific repair positions of large equipment, and complete operations such as boring repair, bolt hole repair, and re-tapping, making them an indispensable solution for equipment maintenance.
III. Comprehensive Adaptation of the Drilling Tapping Machine Industry
Steel structure industry: Used for link processing on H-shaped steel, steel columns, and steel beams, it meets the processing requirements of different cross-sectional size workpieces.
Mold manufacturing also: processes guide pin holes, cooling water channels, and threaded fixing holes on large molds to meet the requirements of multi-position and multi-angle processing.
General mechanical manufacturing: Suitable for processing small-batch parts such as box bodies and flange plates, balancing efficiency and flexibility.
IV. Considerations for Selecting a Drilling Tapping Machine:
Processing size range: Measure the maximum size and weight of the regular processed workpieces to determine the processing range. Key points to focus on:
The distance from the end face of the spindle to the base: This determines the height of the workpiece that can be processed.
Distance from the center of the spindle to the column: This determines the processing range of the workpiece in the horizontal direction.
Swivel arm lifting stroke: Affects the adaptability of processing at different height positions.
Integrated drilling Tapping Machine installation conditions:
Check the flatness of the workshop floor.
Taking into account the need for equipment mobility, some models can be equipped with wheels.
Evaluate whether the power configuration meets the power requirements of the motor (if there are any special requirements, please contact us for customization.)
V. Operation and Precision Assurance of the Integrated Drilling Tapping Machine
1.Standardize operation procedures
Safety Startup Checklist:
Confirm that all locking mechanisms are in the unlocked position.
Check the lubrication condition of the guide rails and ensure that they are well lubricated.
Manually rotate the main shaft to confirm that there is no abnormal resistance.
Carry out no-load test runs and observe that all mechanisms operate normally.
Operating Prohibitions for the Integrated Drilling Tapping Machine:
It is strictly prohibited to change speed during operation. When changing speed, the machine must be stopped first. If necessary, manually rotate the main shaft to assist in the engagement of the auxiliary gears.
Before raising/lowering the rocker arm, the locking nut of the column must be loosened: to prevent damage to the transmission gears.
Avoid prolonged consecutive tapping operations: Prevent the motor from overheating
2.Precision Assurance Maintenance System:
Key points for daily maintenance:
Guide rail lubrication management: Regularly apply the specified lubricant to maintain an oil film on the guide rail surface.
Inspection of exposed friction points: Daily check the lubrication status of each friction area
Cleaning and Maintenance: Remove iron filings and coolant residues in time to prevent corrosion.
Precision verification cycle of the drilling Tapping machine:
During daily processing, the accuracy is verified by measuring the test pieces.
Perform main shaft radial runout detection every six months.
Check the verticality and positional accuracy of the main shaft every year.
The drilling tapping machine, with its multi-functional integration feature, has become an indispensable basic equipment in the modern mechanical processing field. With the continuous development of modular design and intelligent control systems, this classic machine is experiencing a revival and continues to provide efficient processing solutions for small and medium-sized manufacturing enterprises. In today's industrial manufacturing that pursues individualization, the drilling tapping machine, with its unique value, will surely continue to shine on the production frontlines of the workshop.
