The composition of the encoder model is determined by a number of factors, including the type of encoder, body diameter, pulse, and so on. Below we carefully analyze the encoder model, thoroughly understand the meaning of the encoder model. Before you figure out the encoder model, first understand the classification of the encoder. First, the absolute encoder (rotary type) There are many optical channel engraving lines on the absolute encoder optical disc. Each line is arranged in 2 lines, 4 lines, 8 lines, 16 lines... so that each position of the encoder is read by each line. The pass and dark of the reticle, obtain a unique binary code (Gray code) from the zeroth power of 2 to the n-1 power of 2, which is called an n-bit absolute encoder. Such an encoder is determined by the mechanical position of the optical code disc, and it is not affected by power outages and interference. Absolute encoder type label meaning Example: GD64-65536/64BHN-6-30 Photoelectric absolute encoder; main body diameter 64; 65536 yards; continuous loop number 64; parallel Gray code; after the flight insert; counterclockwise increment; working voltage DC6V-30V. Second, incremental encoder Incremental encoders generally give two kinds of square waves, which are 90 degrees out of phase and are commonly referred to as channel A and channel B. Only one channel reading gives information relating to the rotational speed, and at the same time, based on the sequential comparison of the acquired second channel signal with the first channel signal, a signal in the direction of rotation is obtained. Another available signal is called the Z channel or zero channel, which gives the absolute zero of the encoder axis. This signal is a square wave with the same phase as the A channel and the same width as the A channel. Incremental encoder model label meaning Example: GDZ48-360A/BOG6-30 Photoelectric incremental encoder; main body diameter number 48; single turn 360 pulse; two phase; open collector output; side lead; practical voltage range 6~30V. Precision Parts By Five-axis Machining
Precision parts are critical components of various products and machines that require precision and accuracy. The five-axis machining technology has revolutionized precision manufacturing by enabling the production of complex geometries with unparalleled accuracy.
Five-axis machining involves the use of a computer numerical control (CNC) machine that has five axes of motion – X, Y, Z, and two rotational axes. This advanced technology allows the machine to produce intricate and complicated parts with high precision and accuracy. Unlike 3-axis or even 4-axis machining, the five-axis machine can rotate and tilt the tool to machine parts from different angles, providing greater flexibility in terms of geometry and design.
Precision parts made using five-axis machining technology are popular in various applications, including aerospace, medical equipment, automotive, and electronics industry. These parts are designed to meet the most stringent standards, making them reliable and durable. The five-axis machine can achieve tolerances as low as 0.0001 inches, providing superior precision that is unmatched by manual machining.
One significant advantage of using five-axis machining technology is increased efficiency. The five-axis machine can perform multiple operations in a single cycle, reducing the time required to produce a part. It can handle complex designs with ease and produce highly accurate parts, making it ideal for applications that require high precision and accuracy.
Another advantage of five-axis machining is increased design flexibility. It allows designers to create highly complex geometries that were not possible with traditional machining methods. With five-axis machining, it is possible to manufacture parts with undercuts, curved surfaces, and geometries that are difficult to access using other machining processes.
In summary, precision parts made using five-axis machining technology offer superior precision, accuracy, and design flexibility. These parts are widely used in various industries, and their high precision and accuracy make them highly reliable in critical applications. As manufacturing technology continues to advance, we can expect more sophisticated techniques that will offer even greater precision and accuracy.
