ema smart sensors for CNC machine tools
As an important electrical component on CNC machine tools, the wide application of various types of sensors makes the machine tools achieve its high degree of automation and high precision. The sensor is a device or device that can sense the specified detected amount and convert it into an available output signal according to a certain law. The input signal (that is, the detected amount) is a non-electric quantity, and the output signal is often a power that is easier for us to deal with. A large number of sensors are used in a CNC machine tool: proximity switches, pressure sensors, temperature sensors, level sensors, speed sensors and other types of sensors, mainly used to detect position, pressure, temperature and flow.
ema, as a professional sensor manufacturer, has a complete range of sensors for machine tools: Pressure sensors, temperature sensors, speed monitors, intelligent proximity sensors, liquid level sensors, etc., can perfectly meet the strict requirements of large machine tools for speed response, as well as meet the strict requirements of small and medium-sized machine tools and high-precision machine tools for accuracy: 1, high reliability and high anti-interference; 2, high precision and customer requirements for speed; 3, easy to use and maintain, suitable for machine tool applications; 4, low maintenance costs.
The following describes the application of various types of Emaar sensors on machine tools:
1. Proximity switch for position detection:
As the name suggests, when the object is close, there will be a signal output switch, it does not need to be in direct contact with the detected object, the main application of IMA’s proximity switch on the machine tool is in the tool selection control of the tool holder, the stroke control of the workbench, the piston stroke control of the cylinder and the cylinder.
2. Detection of pressure:
The pressure sensor is a sensor that converts the pressure into an electrical signal, and the intelligent pressure sensor of Emma has multiple sets of programmable output signals, which can be fully programmed for the output signal type, with high sensitivity, high repeatability, excellent stability, and suitable for monitoring the workpiece clamping force on the machine tool. When the clamping force is lower than the set value, it will cause the workpiece to loosen, and the system will send an alarm to stop the tool; In addition, it is used in the lubrication system, hydraulic system, and air pressure system to detect the pressure in the oil or gas path. When the pressure of the oil or gas path is less than the set value, the electric shock will act and then send the signal to the control system for control.
3. Temperature detection:
Ima temperature sensor is PT1000/PT100 thermal resistance measuring element, mainly used to monitor the temperature on the machine tool for temperature compensation or overheat protection, machine tool in the work with the rotation of the motor and the movement of moving parts, cutting will generate heat, but the temperature distribution is uneven, will cause a certain temperature difference, The CNC machine tool produces thermal deformation, which affects the precision of the machined parts. In order to avoid these effects, the machine tool will be installed with a temperature sensor, which can immediately transmit the detected temperature value to the control system, and can also be transmitted to the control system when the set point is reached to monitor and control the temperature of the machine tool.
4. Flow detection:
Imma’s flow sensor for fluid (liquid and gas) flow detection is unique, this year IMMA won the German iF product design award of the whole new intelligent flow temperature, this integrated sensor perfectly integrates the temperature and flow detection sensor, can sense the flow and temperature two physical quantities at the same time. And the output is two independent signals, the two outputs can be set separately, very suitable for use in the hydraulic system, lubrication system and cooling device of the machine tool, with an IMar temperature flow integrated sensor can monitor two important parameters, can save money, and more stable.
5. Liquid level detection:
Emma’s product range also includes sensors for level detection, including tuning fork level sensors; Float float type liquid level sensor; Float type liquid level sensor; The capacitive level sensor, among which the small tuning fork and float type level sensor are specially developed and applied in the detection of the level of smaller tanks by IMA Company. At present, a large number of applications are used in the detection of kerosene, lubricating oil, hydrochloric acid, etc., in the lubrication system of machine tools, it is very suitable for the level detection of lubricating oil.
