Debugging the concentricity

Steps:

Install the dial gauge on the spindle of the machine tool, ensuring that its measuring head can touch the outer surface of the measuring head of the edge finder;
Adjust the position of the dial gauge so that its measuring head is perpendicular to the outer surface of the edge finder measuring head;
Install the edge finder on the machine spindle and ensure that it is securely installed;
Manually rotate the spindle of the machine tool (at low speed) and observe the changes in the reading of the dial gauge;
Based on the reading of the dial gauge, determine the direction that needs to be adjusted;
If the dial gauge reading is too large in a certain direction, it indicates that the edge finder is off center in that direction;
Use a wrench or screwdriver to fine tune the corresponding position of the screw, gradually reducing the deviation;
After each adjustment, rotate the spindle again and observe the dial gauge reading until the concentricity of the measuring needle ball head is less than 0.005mm;
After adjusting the concentricity to the correct range, tighten all adjustment screws to ensure that the position of the edge finder is fixed.

Turn off the power of the machine tool and ensure that the equipment is in a power-off state,
Clean the installation interface and measuring head of the edge finder to ensure that there is no dust, oil stains, or impurities
Align the probe tip with the installation interface of the edge finder, ensuring that the positioning pin or keyway of the probe is aligned with the interface, gently insert the probe, and ensure that it is installed in place
During the tightening process, use the provided wrench to clamp the needle seat to avoid damaging the internal structure.

0.001mm Repeatability Accuracy

The repeatability accuracy reaches 0.001mm, which can more accurately locate the edges and feature points of the workpiece;
Ensuring more precise tool alignment and positioning during the machining process, thereby improving overall machining accuracy and reducing errors;
High precision edge finders can quickly and accurately complete tool alignment and positioning, reducing manual adjustment time and errors, thereby improving production efficiency, reducing scrap rates, saving material costs;
Adapting to complex workpieces, and improving automation levels.

The WP-500 wired probe adopts an E-type quick plug interface with a locking mechanism to ensure a stable connection and avoid looseness or detachment caused by vibration or movement.
It has a shielding layer that can effectively reduce electromagnetic interference and ensure the stability of signal transmission.
It is easy to plug and unplug and is equipped with a 3m long 2-core output signal cable.

Calculate deviation value

Contact the measuring head with the two edges of the workpiece and record the coordinate values X1 and X2 respectively.
Due to the diameter of the measuring head (ball head diameter), the actual edge position of the workpiece needs to be compensated by subtracting the radius of the measuring head
The length of the workpiece is known and is used to verify the accuracy of the measurement results
Calculation steps:
Calculate the distance between two measurement points: X2−X1
Subtract the actual length of the workpiece and the diameter of the measuring head to obtain the deviation value, divide by 2 to obtain the deviation value on one side

When do I need to zero？

1. Do not adjust the zero first. Tighten the zero adjustment screw of the measuring head and refer to the video on the homepage to measure the repeatability accuracy. The repeatability value obtained by installing on the machine tool - machine tool repeatability=probe repeatability. (Used to determine if the probe is functioning properly. Before completing this step, there is no need to continue with the next steps. Due to the price of the probe, you will be trapped in endless doubts about its accuracy, wasting time.)
2. When used without connecting wires for rotation, the measuring head can be adjusted without zeroing.
1). Divide the edges into sections: a. Rotating probe with speed less than 600; b. Measure the values of x1 and x2 on the opposite side; c. (x1+x2)/2=center of workpiece
2) Unilateral measurement, due to reasons such as zero adjustment/deflection/fixture, the actual rotation radius of the ball head is different from the ball head radius. Intuitively, it can be seen that the dynamic radius of the ball head needs to be measured: a. Prepare square blocks of known size (which can be workpieces of known size) and place them parallel to the XY axis.; b. Rotating probe with speed less than 600; c. Probe ball head, with the indicator block - X surface light on, the system's processing coordinates are reset to zero;d. Probe ball head, with the reference block and X-face light on, record the machining coordinates.e. (x value in 2.4- length of block in X direction)/2=dynamic radius value of ball head
This value includes the deflection value of the probe, which is not an integer. It is recommended to store this value in the system for future call. (Assuming it is A);f. Measuring workpieces: Measure the system coordinate values of the workpiece surface when the light is on with a measuring head. Based on the actual direction+- A, the precise coordinate values of the workpiece surface can be measured
3). When using the probe without rotation, it must be zeroed first. After zeroing, repeat the above steps.
3. Connected use (involving a lot of content and knowledge, different systems are different, and cannot be explained in detail), a brief reminder is as follows, self research based on the system.
a. The probe must be zeroed first.; b. requires circular or square markers for calibration. (Used to obtain initial standard values); c. Connect the wires according to the system manual, usually in parallel with the tool setter. (Wp-500 red 0 black signal NPN long open):d. For high precision requirements, the measurement needs to be oriented with the main axis. e. System macro program writing, the principle is to store/read and calculate the data obtained from measurement/coordinate axis offset/rotation.
