What is a cnc machine tool probe

According to function classification, can be divided into workpiece detection head and tool detection head

According to the signal transmission mode classification, can be divided into hard wire connection type. Induction type. Optics and radio.

The choice of transmission mode depends on the application.

Install the machine tool probe

The machine tool probe can be installed on the CNC lathe. Machining centers. Most CNC machine tools, such as CNC grinders. During the machining cycle, the size and position of the tool or workpiece can be directly measured without manual intervention, and the offset of the workpiece or tool can be automatically modified according to the measurement results, so that the same machine tool can be processed with higher precision parts.

The characteristics and functions of the probe system of CNC machine tools:

1. Workpiece probe system:

Accurate measurement, calibration of workpiece position, automatic calibration coordinate system.

Quickly correct fixture position and reduce manual adjustment time.

Simplify fixture design and reduce fixture cost.

First time in machine measurement check, no offline.

Improve productivity and consistency of batch processing sizes.

Cyclic measurement, monitoring workpiece size and position, automatic correction of offset quantity.

Shorten the auxiliary time of machine tool and improve productivity.

Enhance confidence in unmanned processing.

Fully automatic operation avoids possible injury to the operator.

2. Tool measurement system:

Quick measurement. Correct tool length and diameter offset values.

Fast. Automatically measure and correct all tools in turret tool holder or tool library.

Avoid manual intervention manual knife error.

Ensure the exact dimensional accuracy of the first piece.

The cutting tool is broken to prevent breakage.

Shorten the auxiliary time of machine tool and improve productivity.

Enhance confidence in unmanned processing.

Why use a probe on a CNC machine tool?

Time is money. Instead of spending time manually correcting the position of the workpiece and inspecting the workpiece, it is better to put it into machining. The head measurement system reduces auxiliary time and workpiece scrap costs with manual correction and inspection tools. Buying a CNC machine means a lot of money. Although it has the ability to cut metal quickly and produce complex workpieces, the machine tool can only express its value when cutting parts. Some machine tools have ineffective auxiliary time, most machine tools will idle for several hours or long periods of intermittent processing. The truth is simple. Many companies still use hand knives. Workpiece correction and off-line inspection can leave expensive equipment vacant. The use of measuring heads reduces auxiliary time and waste and increases processing time. Improve accuracy.

Manual tool setting, workpiece correction and off-line inspection are time-consuming processes and prone to operating errors. Using a probe allows quick tool alignment and avoids expensive fixture costs. The probe software can automatically compensate the tool length. Diameter, workpiece position and dimensional errors. Manual detection with a dial meter on the machine is inefficient, manual measurement is highly dependent on the skills of the operator, or moving the workpiece to the three-coordinate detection machine and other off-line detection methods may take a lot of time, if there is a deviation, it is impossible to install back to reprocessing. Using the probe, the workpiece can be detected quickly and the offset compensation value can be set automatically. Using the probe can save 90% auxiliary time and cut more parts. Reduce auxiliary time for tool and workpiece correction. The measurement software automatically updates tool and workpiece coordinate offset for faster and higher accuracy, reducing scrap caused by tool and workpiece correction errors. The workpiece probe mounted on the spindle can accurately identify the position of the workpiece and detect whether the workpiece is misinstalled. High repeatability of tool and workpiece alignment eliminates workpiece scrap caused by alignment error. Reduce operating costs and expensive fixture costs. Reduce the number of operators. Without the need for expensive precision fixtures, the workpiece probe can find the position of the workpiece using a simple tightening device. Improve process control, test the workpiece, reduce the auxiliary time of offline test. Detecting the main dimensions of high value workpieces is very important for unmanned processing. Tool damage detection and recognition, tool recognition and damage detection, to remind the operator or automatically replace the spare tool, improve safety. Automatic operation of the knife. All machine protective doors remain closed during workpiece alignment or testing.
