Since the 1980s, foreign deep hole drilling machine technology has been developing in a comprehensive and flexible direction on the basis of meeting the requirements of accuracy and efficiency. There are new breakthroughs in the processing accuracy of deep hole drilling machines, the flexibility of multi-species processing and the flexibility and variety of machine tool configurations.     The sequence is highly centralized, highly efficient short beats and multi-function knowing monitoring. The development trend of deep hole drilling machine technology is: (

(1) Wide application of CNC technology: major foreign manufacturers of deep hole drilling machines have their own serialized complete CNC deep hole drilling machine universal parts. On deep hole drilling machines, not only general power components are applied with NC technology, but also the indexing of fixtures or The automatic indexing and positioning of the corners and box changing devices also use CNC technology, so that     In one step, the working reliability and processing accuracy of the deep hole drilling machine are improved. (

    (2) Development of flexible technology: Since the 1980s, foreign countries have adopted a series of adjustable, variable, and interchangeable measures for medium-to-large-scale production and multi-variety processing equipment to make the processing equipment flexible. For example, a deep hole drilling machine composed of a turret power head and an interchangeable spindle box has been developed; at the same time, according to the development of the machining center,     Developed two-coordinate and three-coordinate modular processing units, and on this basis, a flexible processing automatic line (FTL) was formed. This structural change can not only realize the rapid and sensitive adjustment and change of multi-variety processing requirements, but also make the machine tool configuration more flexible and diverse.

    (3) Development of comprehensive automation technology: The rapid development of the automotive industry has put forward many new demands for automated manufacturing technology. The high efficiency of mass production requires that the manufacturing system can not only complete general machining processes, but also complete parts from rough All processes from incoming line to finished product offline, and automatic code after offline     Stacking, packing, etc. A 90 million mark gearbox and clutch shell production line put into use by a large German automobile company KASSEL gearbox plant in 1987 is a model of such an integrated automated manufacturing system. The system consists of two similarly symmetrically arranged automatic lines, working in three shifts, each line producing 2,000 pieces per day     The shooting time is 40 seconds. The whole line is composed of 12 double-sided deep hole drilling machines, 18 three coordinate processing units, empty frame robots, blank warehouses at both ends of the line and three coordinate measuring machines, which can realize the processing of three types of parts. The empty rack robot completes the palletizing and packing of the workpiece off the assembly line. With the development of integrated automation technology, a number of     Professional manufacturers of equipment for assembly, testing, inspection, cleaning, etc. have further improved the matching level of the manufacturing system.

    (4) Further increase the degree of process concentration: In order to reduce the number of machine tools and save area, foreign countries continue to take various measures to further increase the degree of process concentration for products with a high degree of process concentration such as deep hole drilling machines. Such as the use of cross slide table, multi-coordinate universal parts, moving headstock, double head boring car end face head, etc.     Form a machine tool or set up a tool magazine at the fixture location, and realize the process concentration through tool change processing, so as to maximize the effectiveness of the equipment and obtain better economic benefits.
