The Difference between The Movable Guide Sleeve And The Non-guide Sleeve of The CNC Centering Machine.

The difference between the movable guide sleeve and the non-guide sleeve of the CNC centering machine.

The difference between CNC centering machine and CNC tool walking machine is that when processing, the Z-axis direction of CNC tool walking machine is the tool is moving back and forth, while CNC centering machine in the processing, is the front end of the spindle holding the material in the Z-axis direction of the forward and backward movement, and at the same time, with the help of the movable guide sleeve to ensure the precision of the parts, it can be imagined that the movable guide sleeve for the centering machine plays a role, but due to the movable guide sleeve have a certain thickness, and at the same time the spindle But because the movable guide sleeve has a certain thickness, and the spindle clamping material position from the movable guide sleeve also has a certain distance, thus in the CNC centering machine processing products will leave a section of the tail material, resulting in a great waste of material. So do CNC centering machine manufacturers and according to this waste will be active guide sleeve removed, directly to the front of the spindle lengthened so that it can be through the tool holder plate to the tool holder sliding plate. Thus we can see the CNC centering machine with movable guide bush and no guide bush structure of the big difference.

The movable guide sleeve is composed of many parts, including the drive shaft, guide sleeve support frame, guide sleeve outer wall, slewing bearings, the first and second synchronous belt composition, is the spindle rotation through the first synchronous belt rotation drive drive shaft, drive shaft through the second synchronous belt drive movable guide sleeve on the movable guide sleeve and the spindle to achieve the same rotational speed, so that the degree of wear and tear on the raw materials and product precision, the advantages of this kind of centrifugal machine structure The advantage of this kind of centrifuge structure is in the processing of long and thin shafts, higher hardness of materials and higher precision parts, but the tail material is longer, which is easy to cause the waste of raw materials.

　　No guide sleeve in fact is to lengthen the front end of the spindle, remove the movable guide sleeve part, so that it passes through the tool holder plate directly, the advantage of this kind of centering machine structure is that the tail material is shorter, no waste of raw materials, but only suitable for doing the L/D ratio is not big, the material hardness is not high, the raw material is shorter, can't be used to send the material with a feeder for the flat material, and at the same time to the centering machine spindle and the spindle bearings and service life of the machine to cause a certain amount of impact.
