In the fast-evolving landscape of modern precision machining, where every micron of dimensional accuracy directly determines the qualification rate and added value of finished components, the normally open and normally closed integrated wired probe MT25-Plus emerges as a groundbreaking in-machine measurement solution tailored for small and medium-sized high-precision CNC machining centers. Developed to address the long-standing pain point of complex wiring and poor compatibility of traditional wired probes across different CNC systems, this model merges dual signal output modes in one compact body, while maintaining industrial-grade stability that can withstand the harshest workshop operating conditions. It perfectly fits application scenarios ranging from precision mold manufacturing, medical micro-component processing, 3C consumer electronics high-precision batch production to aerospace secondary positioning machining, eliminating the tedious probe replacement and rewiring steps caused by system switching, and helping enterprises greatly reduce equipment deployment costs and improve measurement consistency across the entire production line.
Core Innovative Design & Technical Advantages
The most defining highlight of the MT25-Plus lies in its patented normally open and normally closed integrated signal output structure. Unlike conventional wired probes that can only support a single output mode, this model reserves independent wiring ports for both signal states, allowing operators to freely switch between modes through simple wiring adjustment without modifying the internal circuit of the probe. When the black wire is connected to 24V and the cyan wire is connected to the SKIP signal terminal, the probe enters the normally open operating state; when the black wire is connected to SKIP and the cyan wire is connected to 24V, it automatically switches to the normally closed mode, realizing full compatibility with all mainstream CNC systems on the market including FANUC, HEIDENHAIN, Mitsubishi and domestic self-developed CNC systems. This design fundamentally solves the compatibility problem that traditionally requires purchasing different probe models for different machine tools, making it extremely convenient for centralized equipment management in large-scale machining workshops with multiple mixed system models.
In terms of core precision performance, the MT25-Plus achieves an ultra-stable 0.001mm repeat accuracy when operating within the recommended detection speed range of 30~150mm/min, and its 24.8mm compact outer diameter stainless steel body is equipped with a high-sensitivity precision trigger mechanism. It supports multi-directional contact induction covering ±X, ±Y and +Z axes, with expanded overtravel protection of XY±12.5° and Z-axis 7mm, which greatly reduces the risk of probe damage caused by accidental overtravel of the machine tool during high-speed movement. With an optimized contact force design of 0.9N in XY direction and 1.2N in Z direction, it balances rapid trigger response and gentle contact protection, leaving no indentation on the surface of aluminum alloy, copper, quenched steel and other common processing materials while ensuring no misjudgment of trigger signals.
The entire probe body reaches the industrial IP68 highest-level waterproof and oil-resistant protection rating, which can resist long-term erosion of water-based cutting fluid, oily coolant, metal chips and oil mist inside the enclosed machine tool cavity. The equipped 5-meter dedicated PUR outer sheath shielded cable adopts triple-layer shielding structure with high-tensile Kevlar fiber inside, supporting more than 5 million times of reciprocating bending in the machine tool drag chain, completely avoiding signal distortion or wire breakage caused by long-term movement. The built-in high-precision contact structure supports up to 12 million times of trigger cycles, far exceeding the average service life level of similar products on the market, and can maintain long-term stable performance even under 24-hour uninterrupted high-frequency measurement scenarios.
Practical Application Value in Machining Workshops
For the actual production side, the MT25-Plus brings multi-dimensional efficiency improvements for machining enterprises. On the equipment deployment level, the normally open and normally closed integrated design allows workshops to use a unified probe model across different machine tools with different systems, which simplifies the spare parts management process and reduces the inventory cost of different types of spare probes by more than 60%. On the measurement execution level, the 0.001mm ultra-high repeat accuracy ensures that all workpiece alignment, on-machine size inspection and tool wear compensation data are consistent and reliable, avoiding batch scrap of precision parts caused by measurement error. For example, in the batch processing of precision mobile phone middle frame molds, the MT25-Plus can automatically complete secondary positioning inspection after rough machining, and timely compensate the machining coordinate deviation caused by thermal deformation of the machine tool, reducing the mold finishing correction cycle from the original 2 hours to less than 10 minutes, and the overall machining efficiency is increased by more than 45%.
In terms of daily operation and maintenance, the MT25-Plus is equipped with three independent status indicator lights: the PROBE light flashes synchronously when the probe is triggered, the POWER light keeps on to indicate normal power supply, and the ERROR light will be activated in case of abnormal trigger or circuit fault, allowing operators to quickly identify the working status of the probe at a glance. The standard mounting thread of the probe body is compatible with all mainstream stylus specifications on the market, and users can quickly replace different lengths and different materials of stylus according to the processing scene, realizing flexible adaptation to measurement requirements of different complex feature positions. Even for small deep cavity molds that are difficult to access with ordinary standard probes, the MT25-Plus can smoothly complete size inspection by matching the extended stylus, without the need for secondary clamping of the workpiece, avoiding positioning errors caused by repeated clamping.
