What is the meaning of CNC machine walking? It is actually a spindle box mobile CNC lathe, referred to as the walking machine. Most of the machines on the market can be longitudinal turning, so people often call it a longitudinal CNC lathe. Here to give you a detailed introduction to the meaning of CNC machine walking.

CNC walking machine working principle:

When machining, the tool is kept in a fixed position, the spindle is moved back and forth, which can support multiple feeding and can support the processing diameter of no more than 32mm. The machine with guide sleeve has good rigidity and high precision, which is very good for batch processing of long bar materials. Of course, the machine tool with the guide sleeve will have more or less waste of tail material, because it needs to leave enough space to clamp. The central lathe generally has two cutting modes of guide sleeve and no guide sleeve which can be switched arbitrarily.

Structure analysis of CNC walking machine:

It is mainly composed of a main shaft (auxiliary spindle) and a tool holder.

The spindle can move and rotate, and can be fed multiple times, and the auxiliary shaft is to assist the spindle processing, feeding, and subsequent processing, so as to shorten the product processing time.

The tool rest part has a turning tool, a side power head, a end face fixing seat and a countershaft end milling seat. The turning tool can turn groove, outer diameter, thread, cutting, etc. The side power head can drill, tap, saw groove, milling flat, milling groove, etc. The end face fixing seat is rotated with the main shaft C1, so as to drill, tap, boring, etc. After the auxiliary shaft end milling seat is matched with the auxiliary spindle, drilling, tapping, sawing slot, milling flat, milling groove, etc.

What are the general models of walking machine:

If the model can be divided from the processing diameter, the number of spindles and the number of moving axes, the model produced by different manufacturers will be different.

From the market, the machine can support the processing diameter of no more than 32mm, the general model will be 12, 16, 20, 26, 32. Some may have 38mm, but due to the high development cost and small market demand, few manufacturers will provide this model.

From the number of spindles, there are single spindle CNC walking machines and double spindle CNC walking machines on the market. Among them, the single spindle is also known as the three-axis walking machine, which is composed of the main shaft Z axis and the X and Y axis of the tool holder, and then equipped with the turning tool, the side power head, the end boring tool holder, and a system channel to control. The dual-spindle machine is controlled by two or more independent system channels, in addition to X, Y, Z axis, there is a secondary spindle and multiple moving axes, more suitable for processing complex products.

The processing capacity of the double spindle is better than that of the single spindle, and some processes can not be completed on the single spindle, and the double spindle can carry out a coherent processing, which greatly reduces the overall processing time.

Structure analysis of machine walking tool rest row:

If it is a side row of knives, it is generally used for a large number of knives, and it is necessary to switch the tool frequently. The advantage of this row of knives is to improve processing efficiency, but it is also prone to chip wrapping, and if the knife is arranged too closely, it will affect the use of plug and insert expansion function.

If it is a horizontal knife, it can support a variety of plug and insert expansion functions, the row distance between its power head will be sufficient, and the cutting steel is strong, easy to remove chips, but the tool change time will be slightly longer, because the tool is above the tool holder, the stroke is longer.

Advantages of machining:

The machine can simultaneously carry out turning, milling, drilling, boring, tapping, engraving and other composite processing, saving labor costs on the whole, and the workshop production can realize a multi-machine operation.

The machine is a combination of turning and milling and automation, which reduces the manual assistance time, makes the product production precision better, and improves the product pass rate.

The machine can be combined with the feeding machine to automate production and improve production efficiency.

The efficient operation of the machine reduces the investment in fixed assets, reduces the cost input for the enterprise, and improves the profit.
