CNC Machining Center U Drilling Bit CNC Tools Hole Making High Speed Coolant Indexable WC 3D U Drill Bit with Carbide Inserts

* Indexable U-Drill system.* Uses SPMG WCMT inserts.
* With internal through coolant capabilities.
* Excellent for general purpose indexable drilling.
* General insert grade available for machining Steel, Stainless Steel, Cast Iron




Points to note when using the U-drill:
1. The installation of U-drill should pay attention to the positive and negative direction, which blade is upward, which blade is downward, which faces inward, which faces outward.
2. The center height of the U-drill must be corrected, according to its diameter size to require control range, generally controlled within 0.1mm, the smaller the diameter of the U-drill, the higher the center height requirements, the center height is not good U-drill the second side of the abrasion, the hole diameter will be large, the service life of the blade to shorten the U-drill is small if it is very easy to break.
3. U-drill on the coolant requirements are very high, must ensure that the coolant from the center of the U-drill shot, the coolant pressure should be the greater the better, you can plug up the excess water outlet of the turret to ensure that its pressure.
4. The cutting parameters of U-drill should be in strict accordance with the manufacturer's instructions, but also take into account the different brands of inserts, the power of the machine tool, the machining can be referred to the size of the load value of the machine tool, to make the appropriate adjustments, generally using a high speed, low feed.
5. U-drill inserts should be checked frequently and replaced in time, and different inserts should not be installed in reverse.
6. Adjust the feed amount according to the hardness of the workpiece and the length of the tool overhang, the harder the workpiece is, the larger the tool overhang is, and the smaller the amount of travel should be.
7. Do not use excessive wear of the blade, should be recorded in the production of blade wear and the number of workpieces can be processed in relation to the timely replacement of new blades.
8. Use adequate and correctly pressurized internal coolant. The main function of the coolant is chip removal and cooling.
9.U-drill can not be used to process softer materials, such as copper, soft aluminum.
