what are the differences between a drilling center and a machining center? the drilling and tapping center, also known as the drilling and tapping machine, is a high-speed cnc machine tool that has become popular in recent years. it is mainly used in the processing of aluminum products that are currently very popular. a few years ago, many product shells and parts were mainly plastic parts, which were generally completed with molds. and now more and more products begin to use advanced aluminum alloy materials, which are processed and formed by cnc machine tools at one time, which puts forward higher requirements for processing efficiency. occupy the market and have achieved remarkable results.
the working principle of the machining center is to formulate the process plan according to the part drawings, select the technology or the computer to automatically compile the part processing program, and convert the various movements of the machine tool and all the process parameters required by the part into the information code that the cnc device of the machine tool can accept. and store these codes on the information carrier (perforated tape, disk, etc.), send the information carrier to the input device, read the information and send it to the numerical control device, or use the computer to communicate directly with the machining center to complete the input and output of the part program. output.
although these two machine tools are not unfamiliar to everyone, many new users have many unclear points about machining centers and drilling and tapping centers, and they are not even able to distinguish what is a machining center and what is a drilling and tapping center, so that they confuse the concepts. in response to this phenomenon, the engineers of taicheng cnc will make a comprehensive analysis for you from the following aspects.
1. different size
although the structure of the drilling and tapping center and the machining center are similar, their volumes are completely different. because the drilling and attacking center has the ability to operate at high speed, its mechanical operation flexibility is especially considered in the design. its body has been slimmed down, and the weight of each axis is much lighter than that of the machining center, and since the drilling and tapping center mainly processes workpieces with smaller scales, its stroke is also smaller than that of the machining center. many. therefore, the volume of the drilling and tapping center and the machining center has changed significantly. generally, the volume of the drilling and tapping center is about 2 meters * 2 meters * 2.6 meters, while the common 850 models of the machining centers are generally 2.8 * 2.8 * 3 meters or so.
second, the tool changer system is different
the drilling and tapping center generally chooses the sun-type tool magazine. the tool magazine is generally installed on the upper end of the spindle. the capacity of the tool magazine is generally 16t, and the capacity of the servo tool magazine will not exceed 21t. the machining center generally uses the tool arm type tool magazine, which generally has a capacity of 24t. this tool magazine is generally installed on one side of the column.
3. different processing goals
drilling and tapping centers are generally mainly processing small aluminum parts, which are commonly referred to as products. the scales of the targets it processes are generally relatively small, and large workpieces are rarely presented. for example, the currently popular mobile phone frame, mobile phone shell, mobile phone middle frame and so on. the machining center is mainly used in the field of mold processing, mainly processing steel materials. it can be said that it is an indispensable model in the mold processing industry. generally, it will also be deployed with the mold engraving and milling machine.
fourth, the cutting force is different
due to its structural characteristics, the drilling and tapping center does not have a large cutting force, but it is very sufficient for processing metal materials such as aluminum alloys. of course, it can also process materials such as stainless steel, but generally it does not appear like large cutting like a machining center. machining center z is good at large cutting. through its large torque mechanical spindle, it can easily cope with the large amount of cutting of various hard metal materials, and has strong cutting ability.
