With the advent of the CNC era, the production efficiency of processing equipment has been continuously improved, and high precision and high efficiency have become synonymous with the performance of CNC machining centers. Correspondingly, customers have lower requirements for product prices. In order not to affect corporate profits, this has new requirements for processing costs. Under the premise of not reducing product quality, how to carry out maintenance at a lower cost is a problem that should be considered.

There are many ways to improve maintenance costs, including: improving employee productivity, extending tool life, improving consumables management, and reducing energy consumption. Here is an effective way to extend tool life, improve part quality, and reduce manufacturing costs. It has a remarkable effect on tapping and threading.

What are the types of machining center tools?

The machining of the workpiece by the machining center is mainly realized by tools. The tools used in the machining center are generally CNC tools, which can adapt to the high speed, high efficiency and high degree of automation of the CNC machining center. There are many types of machining center tools, and the classification methods are:

According to the tool structure

It can be divided into integral types; mosaic type, which adopts welding or machine-clamp connection, and machine-clamp type can be divided into two types: non-indexable and indexable; special types, such as composite tools, shock-absorbing tools, etc.

According to the tool material

It can be divided into high-speed steel tools, carbide tools, diamond tools, and other materials tools (such as cubic boron nitride tools, ceramic tools, etc.).

According to the cutting process

It can be divided into turning tools, including outer circle, inner hole, thread, cutting tool, etc.; drilling tools, including drills, reamers, taps, etc.; boring tools; milling tools, etc.

There are many types of tools in the machining center. The commonly used ones are CNC end mills, spot drills, center drills, twist drills, group drills, face milling cutters, round nose cutters, T-shaped cutters, keyway cutters, ball cutters, internal R cutters, Dovetail groove milling cutters, fine boring cutter, reamer, rolling cutter, rotary file, etc.

How to prolong the tool life of machining center

Let's first understand the tap. The tap is a tool for processing internal threads. The tap is the most important tool for manufacturing operators to process threads. There is an essential difference between a tap and a rotor. In short, a drill is used for drilling and is a tool for drilling. Taps are used for threading in holes. They are tools for threading and have commonalities in maintenance.

The wear of the tap, by magnifying inspection of the cutting edge of the tap, found that there were some tiny particles adhering to it. The analysis concluded that these metal particles came from the aluminum alloy workpiece material, and although they were very fine, they still prevented the tap from effectively cutting the thread and were difficult to remove. For the vmc850 machining center with a complete cooling system, the effect of removing these metal particles by increasing the coolant pressure is not ideal.

In view of the above problems, a traditional mechanical operation method can be used to improve. Clean the tap with a brush with nylon bristles, and must do this every tapping cycle. In order to avoid the time-consuming interruption of the tapping cycle caused by the cleaning of the tap on the vmc850 machining center, the nylon brush can be installed on the fixture and programmed through CNC machining so that the tap is close to the fixed nylon before the start of each tapping cycle. The brush cleans the cutting edge once.

The success of a small nylon brush in the tap has been extended to the cutting tools used. Although the effect of prolonging the life of different tools is different, it is a simple and effective method for the cost of only a few dollars.
