What is a drilling and tapping center?

A drilling and tapping machining center is a type of CNC machine tool for cutting metals, commonly known as a "drilling and milling tapping machine", "drilling and milling machine", "drilling and milling machining center", etc. It is currently the fastest and most accurate machine tool in the market that integrates cutting, drilling, and tapping. The drilling and tapping machining center is derived from the vertical machining center, and the machine tool occupies a smaller area and has a smaller machining stroke than the vertical machining center. It is mainly used for processing light and small metals and is not suitable for heavy cutting. The configuration usually adopts a servo-type tool magazine, BT30 spindle, and linear guide rail. According to classification and positioning, the manufacturers of drilling and tapping machining centers each have their advantages. Customers should evaluate the positioning of the machine model to narrow down their selection range for the products they need to process and select a suitable high-quality brand based on the positioning of the machine model. Huaen Intelligence is a high-quality emerging mid-range brand, with well-known international brands such as Fanuc and Brother from Japan. Compared with vertical machining centers, the main characteristics of drilling and tapping centers are small and flexible, fast moving speed, high spindle speed, fast drilling and tapping, and fast tool-changing. The drilling center adopts linear guide rails, with a maximum fast-moving speed of 48m/min or 64m/min. The common maximum speed of the BT30 spindle can reach 20000rpm/24000rpm, and the adjacent tool change time is 1 second. At present, the CNC systems commonly used in drilling and tapping centers in the market are FANUC (Japan), MISUBISHI (Japan), Syntec (Taiwan, China), and iNC (Chinese Mainland). The drilling center is a universal machine tool that can process most materials. However, due to its insufficient cutting force, it is usually used to process lightweight products such as aluminum and copper in bulk. Common products on the market that are processed using drilling and tapping centers include metal frames for mobile phones, couplers, power tools, clocks, coppersmiths, LED lampshades, and other die-casting products.

The difference between a CNC machining center, a CNC lathe and a CNC milling machine

The common feature between CNC machining centers and CNC lathes is installing CNC systems on ordinary machine tools. A lathe equipped with a CNC system is called a CNC lathe, a milling machine fitted with a CNC system is a CNC milling machine, and adding a tool magazine to the CNC milling machine is called a machining center. In terms of the number of axes, CNC lathes control two axes, while machining centers have at least three axes (which can also be four or five axes); From the perspective of processing range, CNC lathes are mainly to process rotating parts, while machining centers can process curved surfaces, grooves, and so on; From the perspective of the tool magazine, CNC lathes do not come with a tool magazine, while CNC machining centers come with an automatic tool-changing system. The difference between CNC machining centers and CNC lathes is that machining centers can exchange machining tools automatically. Install different cutting tools on the tool magazine and use an automatic tool-changing device to replace the machining tools on the spindle in one clamping, achieving multiple machining functions. The workpiece of the machining center completes all processes in one clamping, while the CNC lathe only completes the processing of one process. The basic programming code is the same, but some special instructions may not work between different systems. The machining center has powerful functions and integrates functions such as milling, grinding, hole turning, and tapping, making it a comprehensive CNC machine tool. It can be said that almost any hardware product, mold, or product can be made using a machining center. The power of machining centers is far more than that. They are stable, safe, highly efficient, require less manpower output, produce smooth and textured products, and have good dimensional accuracy. The machining centers are also durable, and can generally be used for at least 10 years. Henan Huaen Intelligent Equipment Co., Ltd. specializes in manufacturing vertical, horizontal, and gantry machining centers. The workpiece can be clamped in one go to achieve multi-faceted processing, including complex processes such as turning, milling, boring, drilling, tapping, and reaming, effectively controlling the form and position tolerances, and ensuring consistent machining quality.

What components are optional for vertical machining centers?

The application of vertical machining centers is pervasive, and their advantages of high machining accuracy and efficiency are incomparable to ordinary machine tools. The body of the vertical machining center is made of high-grade cast iron and undergoes strict natural aging and stress relief processes to ensure its machining accuracy and stability. When you, as clients, place procurement, we, as machining center manufacturers, usually make reasonable recommendations based on your processing requirements and materials. The prices of machining centers with different configurations also vary greatly. The quotation would vary from many factors. As clients, what you need to be concerned about is how to choose the best-fit components for your company. Below is my introduction to you: Optional components for vertical machining centers: System: Common ones include Fanuc and Mitsubishi from Japan, Siemens from Germany, Syntec from Taiwan, and iNC from China. Tool magazine: bucket hat or disc-style tool magazine (mechanical arm tool magazine). Screw: Taiwan-imported high-precision screws or made-in-China brand screws. Fourth and fifth axes: optional. Chip conveyor: chain or spiral type. The spindle brand for vertical machining centers is also important. With the optimization of workpiece materials and the improvement of machining accuracy requirements, there are also many applications of high-speed and high-power electric spindles. After being equipped with a series of related devices that control the spindle temperature and vibration power functions, the safety and reliability of high-speed operation can be greatly guaranteed. The advantages of integral high-precision electric spindle are obvious, with small vibration and less thermal deformation. An independent cooling device is used to control the constant temperature of the rotating C-axis, B-axis, tool mounting electric spindle, and cutting oil. The core constant temperature control system and superior spindle circulation internal cooling system ensure stability during high-speed operation and consistency in part machining accuracy. By selecting suitable components, a cost-effective vertical machining center can not only complete rough and fine machining of parts with one clamping, but also carry out various production processes in small and medium-sized batches, and can fully form automatic line batch production.By selecting suitable components, a cost-effective vertical machining center can not only complete rough and fine machining of parts with one clamping, but also carry out various production processes in small and medium-sized batches, and can fully form automatic line batch production.

What are the differences between gantry machining centers and gantry milling machines?

Gantry machining centers and gantry milling machines are all large CNC machine tools. The processing objects of both are the same, which are large workpieces, such as large castings, sheet metal parts, or large box parts. Both are widely used in the mold processing industry. The machining process of gantry milling machines and gantry machining centers is the same, and their bed structures are also similar. The gantry machining center and gantry milling machine are automated machining-type CNC machine tools controlled by CNC system programs. Both should be classified as high-performance CNC machine tools in terms of machining accuracy and efficiency. The more intuitive difference is that the gantry machining center has a tool magazine with an automatic tool changer, while the gantry milling machine does not. It wouldn't be so hard to tell that the gantry machining center equipped with a tool magazine has an automatic tool-changing function, so it can be said that the machining accuracy of the gantry machining center is higher than that of the gantry milling machine. It is easy to see from the summary that when using a gantry milling machine, manual replacement of suitable tools for different types of machining is required, while gantry machining centers can automatically change tools through a robotic arm.

The difference between a vertical machining center and a horizontal machining center

A vertical machining center refers to a machining center where the spindle is in a vertical state. Its structural form is mostly a fixed column, and the worktable is rectangular without indexing and rotation functions. It is suitable for machining disc, sleeve, and plate parts. A vertical machining center generally has three linear motion coordinate axes and can install a rotating table along the horizontal axis on the worktable, commonly known as a four-axis machining center in the industry. It is mostly used for machining spiral line parts. Vertical machining centers are easy to install, operate, observe machining conditions, debug programs, and have a wide range of applications. However, due to the height of the column and the limitations of the tool-changing device, it can't process parts that are too high. When machining cavities or concave surfaces, chips are not easily discharged, and in severe cases, they can damage the tool, destroy the already machined surface, and affect the smooth progress of machining. A horizontal machining center is a machining center with a horizontal spindle, usually equipped with an automatic indexing rotary worktable. It generally has 3-5 motion coordinates, commonly consisting of three linear and one rotary motion coordinate. After one clamping, the workpiece completes the machining of the other four surfaces except for the mounting and top. It is most suitable for machining box-type parts. Compared with vertical machining centers, horizontal machining centers have convenient chip removal and are beneficial for machining, but they have complex structures and higher prices.
