Hillary Machinery supplies drilling and tapping centers for high-speed drilling, tapping and light milling applications. Also known as drill tap centers, these compact CNC machining centers combine fast spindle speeds, rapid axis movement and quick tool changes to reduce cycle times on small and medium-sized production parts.

Drilling & Tapping Centers for High-Speed CNC Machining

Drilling and tapping centers are compact CNC machining centers designed for applications where speed, rapid tool changes and efficient production are priorities. Commonly called drill tap centers, these machines are particularly effective for parts requiring extensive drilling, tapping and light milling operations.

Their combination of high spindle speeds, fast axis movement and quick tool-to-tool times can help manufacturers reduce cycle time and increase production throughput.

What Is a Drill Tap Center?

A drill tap center is a CNC machining center optimized for fast drilling, tapping and milling operations. Like a vertical machining center, it can perform multiple machining operations under CNC control, but its design typically emphasizes speed, compact construction and rapid tool changes.

Drill tap machines can be an efficient choice when the workpiece does not require the size, spindle torque or heavy-cutting capability of a larger vertical machining center.

Drilling & Tapping Center Operations

Depending on the machine, tooling and workpiece, drilling and tapping centers can perform operations including:

  • Drilling
  • Tapping
  • Thread milling
  • Reaming
  • Countersinking
  • Counterboring
  • Spot drilling
  • Face milling
  • Light pocket milling
  • Contour milling
  • Engraving and marking

Drill Tap Center vs. Vertical Machining Center

Drill tap centers and vertical machining centers overlap in capability, but they are generally optimized for different production requirements.

A drilling and tapping center can be an excellent choice for smaller parts where rapid drilling, tapping, tool changes and light milling dominate the machining cycle. A larger vertical machining center may be more appropriate when the application requires greater workpiece capacity, heavier cuts, larger tools or higher spindle torque.

Advantages of High-Speed Drill Tap Centers

  • Fast tool-to-tool change times
  • High spindle speeds
  • Rapid axis acceleration and positioning
  • Compact machine footprint
  • Efficient drilling and tapping cycles
  • Capability for light milling operations
  • Reduced cycle times on suitable production parts
  • Potential for multiple machines within a compact production area

Drilling & Tapping Center Applications

Drill tap centers are particularly well suited for small and medium-sized components requiring multiple holes, threaded features and light milling.

  • Automotive components
  • Aerospace components
  • Electronics housings
  • Medical components
  • Hydraulic and pneumatic components
  • Industrial equipment parts
  • Aluminum housings and enclosures
  • Brackets and mounting components
  • High-volume precision parts
  • Components with numerous drilled and tapped holes

High-Speed Machining of Aluminum

Drilling and tapping centers can be especially productive for aluminum components where high spindle speeds and rapid machine movement can be used effectively. Housings, brackets, covers and other aluminum components with numerous drilled, tapped and milled features are common applications.

Machine selection should still account for the actual material, cutting tools, required metal-removal rate and surface-finish requirements.

Choosing the Right Drilling & Tapping Center

Selecting the right drill tap center requires evaluating the complete machining process. Hillary Machinery can help compare factors including:

  • Workpiece dimensions and weight
  • X, Y and Z axis travel
  • Table dimensions and load capacity
  • Spindle speed
  • Spindle horsepower and torque
  • Tool magazine capacity
  • Tool-to-tool change time
  • Rapid traverse rates
  • Drilling and tapping requirements
  • Milling requirements
  • Part material
  • Accuracy and surface-finish requirements
  • Production volume
  • Required cycle time
  • Automation requirements

Automating a Drill Tap Center

Drilling and tapping centers can be integrated into automated production systems when higher spindle utilization or reduced operator handling is required. Depending on the application, automation may include robotic machine tending, part-presentation systems or other material-handling equipment.

Because drill tap centers often have relatively short machining cycles, automation should be evaluated carefully to ensure the loading system can support the required production rate.

Drilling & Tapping Center Frequently Asked Questions

What is a drilling and tapping center?

A drilling and tapping center is a compact CNC machining center optimized for high-speed drilling, tapping and light milling operations.

Is a drill tap center the same as a vertical machining center?

Both are CNC machining centers and can perform many of the same operations. Drill tap centers generally emphasize high-speed movement, rapid tool changes and efficient processing of smaller parts, while larger VMCs may provide greater workpiece capacity and heavy-cutting capability.

Can a drill tap center perform milling?

Yes. Drilling and tapping centers can perform milling operations in addition to drilling and tapping. The appropriate amount and type of milling depends on machine spindle capability, tooling, material and the required cut.

What materials can a drilling and tapping center machine?

Drill tap centers can machine a range of materials including aluminum, steels and other machinable metals. The appropriate machine, spindle and tooling should be selected around the actual material and machining requirements.

Why are drill tap centers fast?

These machines are designed around production efficiency, typically combining fast axis movement, high spindle speeds and rapid tool changes to minimize non-cutting time between operations.

Can a drilling and tapping center be automated?

Yes. Drill tap centers can be integrated with robotic machine tending and other automation systems when the part, cycle time and production process support automated loading and unloading.
