Product Description

Stop Production Losses Before They Stop You—Zero Failures, Absolute Certainty

In the relentless pursuit of perfection, an undetected tool failure is more than an inconvenience—it's a profit killer. Wasted materials, scrapped parts, and costly machine downtime end here. Introducing our Physical Contact Breakage Detection System: the uncompromising, industrial-grade solution for shops that accept nothing less than 100% reliability.

The Cost of a Single Unseen Breakage is Staggering. Are You Protected?

Eliminate Scrap & Rework: Catch a broken drill, mill, or tap before it ruins a high-value workpiece. Protect your margins from the first part to the thousandth.
Slash Unplanned Downtime: Automate tool integrity checks right inside the machine. No more manual inspections. No more guessing. Just continuous, confident production.
Prevent Catastrophic Damage: A broken tool left unchecked can lead to a cascading failure, damaging the spindle, workpiece, and machine components. Our detector is your first and best line of defense.
Unlock True Lights-Out Machining: Run your CNC machines with unwavering confidence overnight and over weekends. The system doesn't sleep, so your profits can work around the clock.

Engineered for Certainty: How Unbreakable Reliability is Built In

Absolute Physical Verification
While optical sensors can be fooled by coolant, chips, or shadows, our system relies on a fundamental truth: physical contact. A robust, precision-ground probe makes definitive contact with the tool tip, confirming its presence, length, and integrity beyond any doubt.

Benefit: Ironclad reliability in the harshest machine shop environments. Immune to coolant spray, airborne mist, or lighting conditions.
Brutally Simple, Industrial Tough
This isn't a delicate instrument. The probe and mechanism are built from hardened steel and engineered to withstand accidental impacts, vibration, and the demanding conditions of a high-production floor.

Benefit: A "set-it-and-forget-it" solution that endures year after year, requiring virtually no maintenance and delivering an unbeatable return on investment.
Seamless CNC Integration
The system installs directly into your machine's work envelope and plugs straight into the probe port of your CNC control (e.g., Fanuc, Heidenhain, Siemens, Mitsubishi). It uses standard, familiar G-code macros.

Benefit: Quick and simple installation. Your existing CNC operators can program and manage it with ease, making it a natural part of your workflow.
Lightning-Fast Cycle Within Cycles
The verification cycle takes seconds. The probe rapidly approaches, makes contact, and retracts. This minimal time investment protects hours of machining time by ensuring every tool is perfect.

Benefit: Maximize spindle uptime. The incredibly fast check ensures your machine spends its time making chips, not waiting.
Versatile Tool & Setup Checking
Go beyond simple breakage detection. Use it to verify tool presence after an automatic tool change, or even perform quick tool length setting verification after a changeover.

Benefit: A multi-functional tool that enhances your entire process reliability, from tool management to final part quality.

Certifications

Certified with CE / ISO

100% Double Inspection Before Shipment

Independently verified to meet global safety, environmental, and quality management standards, ensuring that every product is suitable for worldwide industrial applications.

All products in our factory undergo at least two inspections before packaging and shipment: self-inspection on the production line and inspection by quality control staff. This ensures that every item meets strict quality standards.

12-Month Warranty & After-Sales Support

Proven by Global Customer Case

Our commitment doesn't stop at delivery. We provide a full one-year warranty with responsive technical support, replacement options, and remote troubleshooting if needed. Operators can rely on continuous uptime with zero worries.

We have customized and supplied the detector to leading international machine tool manufacturers, such as Doosan, which reflects the trust and recognition our products have earned in professional production environments.

Packaging & Shipping

From Packaging to Delivery, Every Step is Professional

Each unit of the equipment is individually and carefully packaged for maximum protection.
We use export-grade cartons that meet international shipping standards and offer excellent structural strength. The inside of each carton is filled with white EPS foam to absorb shock and prevent damage during transportation. The exterior is reinforced with PP strapping to keep the carton securely closed throughout the journey.

For shipments containing multiple machines, we upgrade the packaging specifications even further to ensure the equipment arrives at the customer's site in perfect condition.

Lead Time:
In-stock standard models can be dispatched within three working days.
For small-batch production orders, the manufacturing lead time is typically 15–30 days.

FAQ

Q1. Which machines is it compatible with?
Compatible with vertical/horizontal machining centers, drilling & tapping centers, CNC milling and engraving machines. Supports carousel or chain-type tool magazines, I/O interfaces, and PMC input points.

Q2. What is the detection accuracy?
Accurately detects various tools with 1 mm precision. Ensure minimal vibration at the installation location for optimal results.

Q3. Will it damage tools?
No. The detection plate has adjustable contact force, preventing any impact on tool life.

Q4. Is installation difficult?
Installation is simple: mount the controller and detection unit, connect to machine I/O, and set up the CNC routine. No machine modifications are needed; setup typically takes a few hours.

Q5. Does it require manual triggering?
No. Fully automatic detection is supported, including automatic machine stop and alarm if a problem is detected.

Q6. What can it detect?

Broken tools, Tool length abnormalities (misalignment or looseness), Improper clamping & Chip entanglement, etc.

Q7. What is the detection rod's lifespan?
Made of high-strength, wear-resistant material, with a typical life of up to 10 million triggers. The rod is replaceable, keeping maintenance costs low.
