1. Product Overview
The Makinopc TD40-A Infrared Wireless Probe is a high-precision contact-type measuring solution developed to cater to the growing demand for accuracy and efficiency in modern precision machining scenarios. Adopting advanced optical signal transmission technology, this probe is specially designed for CNC milling machines, lathes and grinding machines, making it an ideal choice for mass production of parts. It excels at workpiece alignment and 2D in-machine inspection on small and medium-sized CNC machining centers, while automatically compensating for tool wear. This core functionality effectively guarantees the machining accuracy of finished parts, drastically reduces the scrap rate and rework rate, and brings tangible cost savings and efficiency improvements to machining workshops of all scales. The product is updated to version 2026.07.04, with every performance indicator optimized to meet the latest industry standards for precision manufacturing.
2. Core Technical Specifications
Every parameter of the TD40-A probe is carefully calibrated to deliver consistent, reliable performance in harsh industrial environments:
- Signal Output State: It supports integrated normally open and normally closed output modes. The wiring logic is clearly defined: when the black wire is connected to 24V and the cyan wire is connected to SKIP, the probe works in normally open mode; when the black wire is connected to SKIP and the cyan wire is connected to 24V, it switches to normally closed mode seamlessly.
- Repeat Accuracy: Achieves an ultra-high repeat accuracy of 0.001mm under the recommended detection speed range of 30~120mm/min, which meets the strict precision requirements of high-end precision parts processing.
- Signal Transmission Mode: Adopts interference-free infrared signal transmission, which effectively avoids signal loss and misjudgment caused by electromagnetic interference inside the machine tool, ensuring stable and continuous data transmission.
- Stylus Induction Directions: Covers ±X, ±Y and +Z full-direction induction, with overtravel protection of XY±12.5° and Z-axis 6mm, which greatly reduces the risk of equipment damage caused by accidental overtravel of the machine tool during measurement.
- Contact Force: The standard contact force of 1N balances the sensitivity of triggering and the protection of the stylus and measured workpiece, avoiding indentation on the surface of precision parts while ensuring rapid triggering response.
- Contact Life: The built-in precision trigger structure supports up to 10 million contact trigger operations, which means the probe can maintain stable accuracy for a long service life even under high-frequency repeated detection scenarios of mass production.
- Body Material: The main body is made of high-strength stainless steel, which has excellent corrosion resistance and mechanical impact resistance, and can adapt to the mixed environment of cutting fluid, metal chips and oil mist inside the machine tool for a long time.
- Power Supply System: The probe is powered by a 3.6V 14250 lithium battery, and the receiver supports a wide voltage input of 16V to 28V, with the operating current less than 50mA, which achieves low power consumption and long battery life. There are three independent LED indicator lights to display the working status: the PROBE light flashes to indicate the probe trigger status, the POWER&BAT light alerts for low battery, and the ERROR light is activated when a system fault occurs, allowing operators to quickly grasp the equipment status at a glance.
- Protection Performance: It is rated IP68 for waterproof and oil resistance, which can resist the erosion of most common cutting fluids and oil stains in the workshop. The receiver cable is 5 meters long with oil resistance, and the length of the cable and metal protection tube can be customized according to actual on-site layout requirements. The receiver bracket is equipped with a magnetic suction component, which does not require additional drilling and punching during installation, greatly reducing the difficulty and time cost of on-site deployment.
- Operating Environment: The normal working temperature range is -5℃ to 40℃ (no frosting), which can adapt to the temperature changes of most ordinary processing workshops.
- Appearance Dimension: The outer diameter of the probe body is 40mm, the overall dimension tolerance is controlled within ±0.1mm, which can be easily installed on various types of small and medium-sized CNC machining centers without additional modification of the tool holder.
3. Key Usage Guidelines
To fully exert the performance of the TD40-A probe and extend its service life, please strictly follow the operation specifications during daily use:
- First, it is recommended to add a 0.5-second delay after triggering the M code of the machine tool, which can effectively avoid mis-triggering of the probe caused by the instantaneous jitter of the machine tool movement, and ensure the stability of measurement data.
- Second, when the probe is impacted by high-pressure coolant or violent water spray for a long time, it is necessary to install an additional customized protective cover to avoid damage to the internal optical transmission window and trigger structure by strong impact.
- Third, during online inspection, the detection speed must be strictly controlled within the range of 30~120mm/min, and the detection speed must be kept completely consistent every time, which is the core premise to maintain the 0.001mm repeat accuracy of the probe.
- Fourth, for the power supply wiring, it must be ensured that the 0V terminal of the power supply is connected to the machine tool ground (zero point). If negative pressure power supply is used, an additional fuse must be installed in the circuit to avoid burning out the probe circuit due to abnormal current.
4. Application Value in Modern Machining
In the current fiercely competitive precision manufacturing industry, the TD40-A probe brings revolutionary production improvement for processing enterprises. Before the widespread use of on-machine inspection probes, operators often needed to spend a lot of time on manual alignment of workpieces, which not only had low efficiency but also could not avoid human-induced alignment errors, leading to batch scrapping of parts in serious cases. After installing the TD40-A probe, the machine tool can automatically complete the workpiece alignment and size inspection in the entire machining process without unloading the workpiece from the worktable, which saves the tedious steps of transferring the workpiece to the CMM for inspection. At the same time, its automatic tool wear compensation function can correct the tool offset in real time according to the detection data after each batch of parts is processed, to avoid the dimensional deviation of processed parts caused by tool wear, which can reduce the scrap rate of precision parts by more than 70% in actual production, and the comprehensive return on investment of the equipment can be recovered in a very short cycle.
