2018-12-26

Deep hole drilling machine, different from traditional hole processing methods, mainly relies on specific drilling techniques (such as gun drilling, BTA drilling, jet suction drilling, etc.) The special machine tools for drilling are collectively referred to as deep hole drilling machines. It represents an advanced and efficient hole machining technology with high precision, high efficiency and high consistency.

Features

They represent advanced and efficient hole processing technology, which can obtain precise processing results in one pass. The processed holes have accurate positions and good dimensional accuracy; high straightness, coaxiality, and high surface finish and Repeatability. It can easily process various forms of deep holes, and can also solve various special types of deep holes, such as cross holes, inclined holes, blind holes and flat-bottom blind holes. It can not only be used to process deep holes with large aspect ratio (up to 300 times), but also can be used to process precision shallow holes, and its minimum drilling hole diameter can reach 0.7mm.
Status Quo of Deep Hole Drilling Machines in China

After my country's entry into the WTO, the opportunities and challenges faced by the manufacturing industry coexist. Enterprises in the deep hole drilling machine industry have adjusted their strategies in a timely manner and adopted active coping strategies. There has been a good momentum of production and sales. Enterprises in the drilling machine industry only have deep-hole drilling machines. According to incomplete statistics, the output has reached more than 1,000 units, with an output value of more than 390 million, an increase of more than 10% compared with 2004. In addition, the added value of the deep-hole drilling machine industry, product sales rate, Economic indicators such as the total salary of all employees and the value of export fees have increased to varying degrees. New products and new technologies have increased significantly compared with last year, which shows that the industry and enterprises are operating in good condition.

(1) Changes in the product structure of industrial enterprises: enterprises in the deep hole drilling machine industry are mainly aimed at automobiles, motorcycles, internal combustion engines, agricultural machinery, construction machinery, and chemicals.

Machinery, military industry, energy, light industry and home appliance industries provide special equipment. With the further integration of my country's entry into the WTO and the world's machine tools, the products of the deep hole drilling machine industry enterprises have begun to change to numerical control and flexibility. Judging from the production situation of enterprises in the past two years, the market demand for CNC machine tools and machining centers is on the rise, while the traditional drilling, boring, and deep-hole drilling machines have a downward trend. "Main Economic Indicators Statement" is a statistical data showing that only from the production situation of several large key enterprises in the country, in 2003, 890 CNC machine tools were produced, with an output value of 161.87 million yuan, and 148 production and processing centers, with an output value of 57.7 million yuan; There are 985 machine tools, with an output value of 258.38 million yuan, and 159 production and processing centers, with an output value of 70.99 million yuan. In 2005, as of April, the output value of CNC machine tools, machining centers, and the output value was close to the level of 2003. Development of refined manufacturing technology and complete sets of process equipment.

(2) From 2001 to 2002, in less than two years, more than a dozen enterprises have implemented shareholding system transformation, and some small factories have almost all withdrawn from the state and become privately owned. Now, some key state-owned enterprises are also considering shareholding system transformation. , the transformation of the system has become irresistible. "The private economy has experienced four stages from being discriminated, being despised to being underestimated, and now being highly valued." The form is developing rapidly.

(3) Current status and development trend of deep hole drilling machine technology and equipment: Deep hole drilling machine and its automatic line are manufacturing technologies and complete sets of process equipment that integrates mechanical and electrical machinery and is highly automated. It is characterized by high efficiency, high quality, economical and practical, so it is widely used in construction machinery, transportation, energy, military industry, light industry, and home appliance industries. my country's traditional deep hole drilling machine and deep hole drilling machine automatic line are mainly controlled by machine, electricity, gas and hydraulic pressure. Its processing objects are mainly large and medium-sized box and shaft parts with relatively large production batches (deep hole developed in recent years). Drilling machine processing connecting rods, plates, etc. also account for a certain share), complete drilling, reaming, reaming, processing various threads, boring holes, turning end faces and bosses, boring various shapes of grooves in holes, and milling planes and molding surfaces, etc. There are many types of deep hole drilling machines, including large deep hole drilling machines and small deep hole drilling machines, single-sided, double-sided, three-sided, horizontal, vertical, inclined, compound, and multi-station rotary table deep-hole drilling machines, etc. ; With the continuous advancement of technology, a new type of deep hole drilling machine - flexible deep hole drilling machine is more and more popular among people. Replacement, with programmable logic controller (PLC), digital control (NC), etc., can arbitrarily change the work cycle control and drive system, and can flexibly adapt to a variety of adjustable and variable deep hole drilling machines. As the deep hole drilling machine and its automatic line is a high-tech special product with high technical comprehensiveness, it is designed according to the special requirements of users. It involves processing technology, tools, measurement, control, diagnostic monitoring, cleaning, assembly and testing. leakage technology. The overall technical level of deep hole drilling machines and their automatic lines in my country is relatively backward compared with developed countries. Some high-level deep hole drilling machines and automatic lines required in China are almost all imported from abroad. The large-scale import of process equipment will inevitably lead to the expansion of investment scale and increase the production cost of products.
