What Distinguishes Industrial-Grade Automatic Drilling Tapping Machines?

Automatic drilling and tapping machines can complete drilling and tapping operations in a single continuous cycle. These integrated CNC systems eliminate the need for manual tool changes and maintain a positioning repeatability of ±0.01mm, even in a three-shift production mode.

Material Compatibility & Performance

Operating Principle

Single Cycle Machining: The integrated spindle motor employs a programmable clutch system, enabling switching between drilling and tapping modes within 0.3 seconds.

CNC Synchronization: The Fanuc/Mitsubishi control system coordinates feed speed (50-800 mm/min) and torque limiting (5-200 Nm).

Fault Prevention: Automatic reverse rotation of broken taps and tool wear compensation sensors.

Workpiece Clamping: Pneumatic vacuum clamping with a repeatability of 0.01°, suitable for batch processing.

Automatic drilling  tapping machine FAQ

Q: What maintenance plan is needed to ensure the continuous and stable operation of the automatic drilling tapping machine?

A: Please follow these machine tool maintenance procedures: Daily: Remove metal shavings from the guide rails and check the oil level in the lubrication tank; Weekly: Measure spindle runout with a dial indicator (accuracy ≤ 0.002mm) and test coolant concentration with a refractometer; Monthly: Relubricate the ball screw with grease and check the alignment of the servo motor encoder; Replace the motor carbon brushes every 500 hours and check the spindle belt tension.

Q: How do these machines prevent tap breakage when machining carbide threads?

A: We employ three safety measures verified in our die workshop:

Real-time torque control: Automatically reverses the rotation direction if resistance exceeds the tool's safe load curve.

Collision stop: An infrared sensor triggers an emergency stop within 0.15 seconds after a vibration peak occurs.

Pulse cooling: Cutting fluid is delivered to the cutting area at a pressure of 10 bar, which is crucial for machining stainless steel and titanium alloys.

Q: Can these devices be connected to our existing production monitoring system?

A: Factory floor integration supports the following methods:

Communication: Via Ethernet using the MTConnect protocol

Shop floor software: Direct connection to Siemens MindSphere or Rockwell FactoryTalk

Output data: Real-time part/tool counts and spindle load charts

Hardware interface: Standard RJ45 connector and MSR card reader for job tracking

Modern automatic drilling tapping machines can improve thread quality by 40-70%, while saving approximately 3.2 operators per 1000 parts, thus reducing labor costs.
