Torque-Monitored Thread Tapping Machine by Taurox

The Taurox thread cutting machines offer three flexible start modes that ensure precise and reliable machining – perfectly matched to your workpiece and production requirements.

Start via Start Button

In this manual mode, the spindle is positioned by hand onto the workpiece. Pressing the start button initiates machining exactly at the defined starting point.

Special feature: When combined with a pneumatic feed, the machine automatically detects the contact point with the workpiece – a pressure sensor simulation automatically sets the workpiece zero point. The process then starts immediately at the preset speed.

Start at Workpiece Zero Point

The spindle starts automatically as soon as it leaves its idle position – whether positioned manually or automatically. Once the predefined zero point is reached, the machining process begins.

Advantage: With the option of defining a second zero point, workpieces with multiple height levels can be machined efficiently in a single sequence – ideal for components with steps or varying surfaces.

Start by Torque Detection

This advanced start mode detects the beginning of machining via an adjustable torque threshold. As soon as this value is reached, the machine automatically begins the threading process.

Especially suitable for:

• Workpieces with varying zero points
• Complex geometries without a clear reference surface
• Flexible or semi-automated production setups

Note:
Not suitable for very small threads or in combination with the “thread re-cutting” mode. The depth accuracy is slightly lower than with the other start modes, but this method offers maximum adaptability.

Conclusion:
With the three start modes, you can tailor your Taurox thread cutting machine precisely to your production environment – for greater flexibility, reliability, and productivity.

The Taurox thread cutting machines support a wide range of specialized machining modes that can be precisely tailored to your specific application. All parameters can be configured via the intuitive control interface – ensuring maximum process reliability, repeatability, and quality.

Thread Cutting – Blind Hole

Designed for precise cutting of blind-hole threads where the thread depth is limited.

Adjustable Parameters:

• Chip Breaking: Can be activated to reduce chip accumulation.
  • Initial chip break depth (1.0–50.5 mm)
  • Interval depth (0.5–25.0 mm)
  • Retract angle or distance (e.g. 45°/90°/180° or 0.5–12.5 mm)
• Reversing: Number of reverse movements during cutting (3–15 per cycle)

Benefit:
Improves chip evacuation, extends tool life, and reduces the risk of tool breakage – especially with long-chipping materials.

Thread Cutting – Through Hole

For open-thread holes where the tool passes completely through the workpiece.

Adjustable Parameters:

• Braking Depth: Optional
  • Automatic: Machine calculates the retract position to protect the thread
  • Manual: Fine adjustment (0.0–6.0 mm)

Benefit:
Enables high cycle speeds with consistent process safety thanks to controlled retraction.

Thread Recutting

Used for reworking existing threads, e.g. removing coatings or burrs.

Adjustable Parameters:

• Torque Reduction during the lead-in phase (10–90%)
• Stop Depth to limit the reduction phase (0.2–80.0 mm)

Benefit:
Prevents damage to parts and tools when refreshing existing threads – ideal for delicate materials.

Thread Forming

Chipless thread production by plastic deformation – no chip formation required.

Special Features:

• No chip breaking necessary
• Ideal for high-strength materials and tight-fitting threaded connections

Benefit:
Increased thread strength, no rework or chip disposal required. Longer tool life with proper lubrication.

Thread Insert Installation

For precise insertion of threaded inserts such as Helicoil or Ensat.

Adjustable Parameters:

• Shutoff Criterion: Selectable via torque or depth

Benefit:
Precise, automated insertion – perfect for series production or repair operations.

Screw Driving / Reaming

Combined operation mode for controlled screw installation with optional reaming process.

Adjustable Parameters:

• Depth-based Stop
  Advantage: Defined screw depth
• Torque-based Stop
  Advantage: Protection against overtightening
• Depth Progression (0–10): Synchronization between rotation and feed
• Release Height (5 mm up to full stroke): Early restart after feed completion

Benefit:
Ideal for assemblies requiring precise torque or insertion depth. The optional reaming process optimizes fits and surface finish.

Thread Gauging

Used for verifying thread accuracy and tolerance via a gauge or plug gauge directly on the machine.

Adjustable Parameters:

• Torque Boost on Reverse (10–4000%): Increases reverse torque for reliable Go/No-Go inspection

Benefit:
Fast, documentable thread quality inspection integrated directly into the production process – ideal for in-line quality assurance.

Conclusion:
The machining modes of the Taurox thread cutting machines cover the full range from standard threading to testing and specialized assembly tasks. With targeted parameter configuration, each mode can be precisely adapted to your material, tolerances, and quality requirements.
