The Influence Of Gear On CNC Milling Parts
Weimi Hardware Tech. Company | Updated: Aug 03, 2017

The Influence of Gear on CNC Milling Parts
Gears in the CNC Milling Parts play a role in transmission, is a very important auxiliary processing parts, gears directly affect the normal operation of the milling machine, but also has a great impact on the service life, mainly in the processing of the advantages and disadvantages of the workpiece, So we have to choose the appropriate gear according to the following requirements.
 1.CNC Milling Parts used by the need for a good processing technology and heat treatment, easy to improve the overall performance of the milling machine;
  2. The surface of the gear must have sufficient hardness and wear resistance, can effectively prevent the gear surface wear or corrosion;
  3. The center hole of the gear must be of sufficient strength and good toughness in order to prevent the gear from breaking, otherwise the processing time, the load is very large in the case of easy to break the root of the gear, thus affecting the use and production progress.
Visible good gear for CNC Milling Parts processing is still very important, good gear to have high strength, high toughness and heat treatment characteristics.
  CNC Milling Parts and the workpiece in contact with the workpiece part of the direction of rotation and the same direction of the workpiece into a smooth milling, and vice versa for the reverse milling; Here we give a brief introduction to the characteristics of the latter two.
 1.CNC Milling Parts with the characteristics of milling
When the cutter teeth are in contact with the workpiece, the cutting thickness is zero, and only when the knife teeth are slid over the cutting surface left by the previous knife teeth, the cutting thickness of each knife is gradually changed from small to large A distance, cutting thickness to a certain value, the teeth really began to cut. Since the direction of the horizontal milling force is the same as that of the workpiece feed when milling, when the force of the tool teeth is large, the worktable will have a gap between the screw and the nut. The smoothness of the cutting process, affecting the quality of the workpiece processing, and serious damage to the tool; due to the greater friction between the teeth and the workpiece, so the surface of the cold chilled phenomenon is more serious.
CNC Milling Parts to choose to follow the milling, the knife teeth on the workpiece through the distance than the reverse milling, knife teeth each time by the workpiece surface cutting, should not be used to process the hard skin of the workpiece, the average cutting time milling Thickness, cutting deformation is small, compared with the reverse milling power consumption less.
  2. Features of reverse milling
    The reverse milling makes the cutting thickness gradually change from large to small, and the sliding distance of the tooth on the cutting surface is very small. Since the direction of the horizontal cutting force acting on the workpiece is opposite to that of the workpiece feed, the table The screw and nut can always keep a side of the thread tightly fit.
    Therefore, under the same cutting conditions, CNC Milling Parts the use of reverse milling when the tool is easy to wear; visible milling and reverse milling have their own advantages and disadvantages, the specific use of which milling method or according to the requirements of the workpiece is processed, the requirements of the surface smooth High degree of use with the smooth milling, and vice versa using reverse milling.
