CNC floor-type boring and milling machine: high growth leading the modern processing trend

[China Machine Tool Business Network Market Analysis] CNC floor-type boring and milling machines are mainstream products in the machine tool industry. Driven by demand, the production of CNC floor-type boring and milling machines in China has maintained rapid growth, leading the trend of modern machining with their new design concepts. The structure types, featuring no-boring-spindle ram-type designs and interchangeable milling heads based on the concept of high-speed machining, have shown their charm and demonstrate a strong trend of replacing traditional milling processes. Various milling head attachments, represented by two-axis swiveling milling heads, have become the main means of achieving high-speed, high-efficiency composite machining, offering wider process capabilities, higher power, and stronger rigidity, marking a significant breakthrough in the development of floor-type milling and boring machines.

In recent years, domestic CNC floor-type boring and milling machines have made tremendous progress. Experts predict that CNC machine tools will continue to grow at an annual rate of up to 25% in the coming years. In particular, CNC floor-type boring and milling machines are expected to see a significant increase in sales revenue. These machines are equipped with a comprehensive range of functional components, with a self-sufficiency rate of about 60%, and domestically developed CNC systems account for about 75% of total production. In recent years, companies have increased investments and focused on the development of CNC floor-type boring and milling machines.

Hanchuan CNC Machine Tool Company launched a new precision CNC floor-type boring and milling machine in 2014, specifically designed for machining large box-type parts, highlighting its advanced technology in this field.

Yang Yonghou, the general manager of Qingdao Yunchi Heavy Industry Machinery Co., Ltd., also stated that after extensively studying the domestic and international markets, the company decided to concentrate its technical forces on independently developing CNC floor-type boring and milling machines, which are now in production. The product adopts CAD optimization and modular design. Based on the existing series of products, the structure and parameter data of the product can be appropriately modified according to the special requirements of users. Various accessory milling heads, tool magazines with different tool capacities, and other auxiliary devices such as cooling units can be configured according to the requirements and types of different machining parts for users to choose from. It is widely used in the numerical control machining of various heavy, large, and medium-sized precision parts in industries such as locomotives and rolling stock, automobiles, aerospace, textile machinery, machine tools, motors, and molds. The project has a total investment of 610 million yuan, covers an area of 194 acres, and has a planned construction area of 146,000 square meters. It is a key construction project in Qingdao.

Since CNC floor-type boring and milling machines are mainly used for machining large parts, they offer a wide range of milling processes, especially high-power, heavy-duty cutting, which is a major processing advantage of floor-type milling and boring machines and a traditional process concept. However, the technological development of contemporary CNC floor-type boring and milling machines is changing traditional process concepts and machining methods. The concept of high-speed machining is replacing the traditional concept of heavy cutting, bringing changes to machining processes through high speed, high precision, and high efficiency, thereby promoting structural changes and technological advancements in floor-type milling and boring machines.

CNC floor-type boring and milling machines are mechanical processing equipment that integrates multiple advanced technologies, suitable for finish machining, semi-finish machining, and rough machining. The installation location of CNC floor-type boring and milling machines is very particular, requiring avoidance of direct sunlight, humid environments, large temperature gradients, and proximity to vibration sources to prevent internal components from malfunctioning due to poor contact, which can seriously affect the machining accuracy of parts. When connecting the power supply of a gantry-type boring and milling machine, a stable voltage must be ensured, and voltage fluctuations must be within the specified range; otherwise, damage to the machine's motor may occur, leading to accidents and processing failures. The ambient temperature of the working environment should be below 30°C, with a relative humidity of less than 80%, and the power supply box should be equipped with an exhaust fan to ensure a constant temperature for all components. Otherwise, excessively high temperature gradients can affect the service life of the control system, and excessively high humidity can cause dust on the circuit board to stick, leading to system short circuits.

According to the results of the integration of informatization and industrialization assessment, the overall situation of single-application informatization in CNC floor-type boring and milling machine industry enterprises is relatively good, and information integration applications have also reached a certain scale and level. However, the level of comprehensive integration, collaboration, and innovation among information systems still needs to be improved. Among them, smaller-scale enterprises face greater difficulties in achieving comprehensive integration, collaboration, and innovation due to constraints such as late starting points, insufficient basic investments, and irregular management.

There is a lack of information systems that meet industry needs. Information systems are the foundation of enterprise informatization and industrialization integration. Currently, the market lacks information systems that are well-suited for CNC floor-type boring and milling machine enterprises, making informatization and industrialization integration efforts often less effective and difficult to achieve expected goals. Industry standards are lagging, and the degree of standardization for informatization and industrialization integration is insufficient. Establishing informatization construction standards suitable for the CNC floor-type boring and milling machine industry is of great significance for standardizing and promoting in-depth informatization and industrialization integration in industry enterprises.

Today, the most notable feature of the development of CNC floor-type boring and milling machines is their evolution towards high-speed milling, all adopting ram-type (no-boring-spindle) structures and equipped with various milling head attachments with different process capabilities. The advantage of this structure is that the ram has a large cross-section, good rigidity, long travel, fast movement speed, and is easy to install various functional attachments, mainly high-speed boring and milling heads, two-axis double-swiveling milling heads, etc., which maximize the process capabilities and machining range of CNC floor-type boring and milling machines, significantly improving machining speed and efficiency.
