Wired Touch Probe Sensor for CNC Lathes [K3S Series]

An Ultra-Compact, Wired Touch Probe Sensor for CNC Lathes K3S Series

Compact touch probe for use on automatic lathes and NC surface grinders

The K3S series is an ultra-compact, wired touch probe sensor.
Designed with the industry's smallest diameter of φ17.8 mm to match the size of the tool holder, the sensor does not take up space and does not interfere with other tools. Especially on CNC automatic lathes and small multitasking machines, it measures the end face of the workpiece to determine the machining origin and outer and inner diameters. Additionally, it is used for grinding wheel wear detection on cylindrical grinders and workpiece height measurement on NC surface grinders.
It reduces the burden of the inspection process and contributes to improved productivity.

It operates at the moment the measuring element contacts the workpiece, enabling highly accurate position detection with a repeatability of 1μm.

When mounted on high-precision processing machines such as NC grinders and CNC automatic lathes, it acts like a simple 3D measuring machine.
It eliminates manual variation in workpiece measurement and reduces setups such as moving and setting workpieces for inspection, thereby realizing cost reductions.

Smallest diameter for machine tools

Smallest diameter for machine tools

The smallest diameter is φ17.8mm to φ19.05mm, and the main unit is designed to fit tightly into the milling holder of a lathe or other machines.
It can be mounted on a grinding machine or CNC lathe with limited space without interfering with other tools.
*In the picture, the main unit is clamped and the side is fixed with an set screw for installation.

Principle Structure

By placing the touch-probe on the stylus tip against the workpiece or table, a high-precision ON/OFF signal is output, which can be input to NC/PC equipment.

The moving part swings with the three points of contact as fulcrums. Since the contacts play the role of fulcrums, a momentary ON/OFF signal is output when one of the fulcrums is detached.

It is recommended to supply power only during measurement to protect the contact-point.
(*The contact force varies depending on the direction of detection. If the contact force varies depending on the detection direction, a perfect circle will not be formed when measuring a perfect circle shape (roving phenomenon), and thus it is necessary to take this specific quality into account.)
