Description

Combined type low-chatter T-shaped slot milling cutter for fine iron machining

Technical Field

The utility model relates to a milling cutter technical field specifically is a T type slot milling cutter that quivers is hanged down to smart iron processing combination formula.

Background

The T-slot milling cutter may be classified into a taper shank T-slot milling cutter and a straight shank T-slot milling cutter. The milling cutter for T-shaped slot is used for processing T-shaped slot on various machine table tops or other structures, and can be divided into a taper shank T-shaped slot milling cutter and a straight shank T-shaped slot milling cutter. The application is as follows: the method is used for processing T-shaped grooves on various machine table tops or other structures. Characteristics and precision: the milling cutter is a special tool for processing the T-shaped groove, after the straight groove is milled, the T-shaped groove with the accuracy meeting the requirement can be milled at one time, the end edge of the milling cutter has a proper cutting angle, the cutter teeth are designed according to the inclined teeth and the staggered teeth, the cutting is stable, and the cutting force is small. Specification description: t-slot mills are generally described in terms of their type: the diameter (external diameter) of the disc and the tooth part, the thickness (blade part length) of the disc, the number of teeth (blade number), the diameter (handle diameter) of the handle part, the total length and the T-shaped slot milling cutter generally adopt high-speed steel and hard alloy, and if the T-shaped slot milling cutter is used for processing common free-cutting metal (below HRC 30), the T-shaped slot milling cutter can be made of the high-speed steel. If the hardness of the processed material is high or the processed material is difficult to cut, the hard alloy is preferably selected to be made. The T-shaped slot milling cutter made of hard alloy has two types of integral milling and welding, the cost performance is high, the alloy is welded (the cost is saved by inserting the alloy), if the processing requirement is high and the precision requirement is high, the integral hard alloy is recommended to be used for manufacturing, but the price is much higher.

The current T-shaped groove milling cutter is used for processing T-shaped grooves on various mechanical table tops or other structures, the traditional T-shaped groove milling cutter is easy to vibrate and affect the flatness of a processed T-shaped groove due to the fact that the fixing strength of a cutter bar and the cutter head is not enough in the using process, and the cutter head is easy to damage by the milling cutter in the processing process. Therefore, the combined type low-chatter T-shaped slot milling cutter for fine iron machining is improved.
