一. Precision
Accuracy includes accuracy and precision, as described below:
1. Positioning accuracy (accuracy)
The maximum difference (absolute value) between the distance reached by the reference point and the original distance is called the positioning accuracy.
2. Reproducibility of round-trip position (precision)
or specify bit reproducibility, which indicates a linear slide stage
During the round-trip movement, the position difference value measured at a set position is called the round-trip position reproducibility by the maximum value in the whole journey.
3. Walking parallelism
1) Refers to the parallelism between the slide plane of the platform and the module installation plane. The gauge stand is in the center of the slide plane, and the pointer is placed on the mounting plane to take the maximum difference measured by the whole stroke.
2) Refers to the parallelism between the slide table of the platform and the module installation datum. The gauge stands in the center of the slide plane, and the pointer is placed on the mounting datum on the side of the module, and the maximum difference value of the full-stroke measurement is taken.
2. Speed:
1. Maximum linear speed
The maximum linear speed (V) of the linear slide stage is calculated by multiplying the maximum speed of the ball screw (S) by the lead (L). V(mm/sec)=5(rpm)-=60×L(mm)
二. Maximum speed
It means that the maximum allowable rotation speed of the ball screw is determined by its critical speed. Resonance may occur when the lead screw speed exceeds the critical speed. The critical speed is related to the length of the lead screw, so the critical speed of the ball screw also indirectly determines the effective stroke and total length.
The maximum allowable speed of the ball screw is calculated as follows:
3. Acceleration and subtraction speed:
The so-called speed refers to the operating speed set by the slide, which must accelerate from the stop state, maintain the speed to move to the destination after reaching the working speed, start to slow down before arriving, and finally stop.
The acceleration and deceleration speed is determined by the user according to the actual use needs of the ball screw stage
The acceleration is calculated as 0.15G for leads below 5, and 0.3G for other leads.1G=9.8m/s'; then 0.15G=1470mm/?; 0.36=2940mm/s'. ball screw stageThe maximum movable mass depends on the acceleration.*Note:
The acceleration and decreasing speed will cause an inertial load on the mass of the handling, and the larger the speed of acceleration and decreasing, the smaller the mass that can be moved. Excessive acceleration and decreasing speed will produce a large impact force and should be avoided.
4. Acceleration and Deceleration
The work cycle is determined by the customer's actual needs. The commonly used work cycle is shown in the figure below, including acceleration time Ta, constant speed time Tc, deceleration time Td, and dwell time Tf.
三. Installation:
For ball screw stages, if the intended use is vertical (Z-axis), please note that vertical installation is a special usage condition. The load should be within the maximum listed movable weight (upright). Otherwise, timing belt types are prohibited from vertical usage.
四. Maintenance:
The parts of the linear platform that require maintenance include the ball screw, U-type guide rail, and related components. Every three months, or after traveling 100 kilometers, lubricants must be replenished on the ball screw and linear guide rails. Please also check for any dirt or debris in the system.
