However, after CNC processing, the surface of many products is still relatively rough, so secondary surface finishing is required at this time. At the moment, precision parts are processed by CNC in many different industries. Do you have any idea how the parts of robots are manufactured and processed? This time, let's talk about the machining industry!

1. Making a Turn

Processing on a lathe, also known as turning, falls under the category of mechanical processing. The primary purpose of turning tools in lathe machining is to turn rotating mechanical components. Lathes are the type of machine tool that are utilized the most frequently in manufacturing and repair facilities for mechanical equipment. Their primary purpose is to perform operations on revolving-surfaced CNC components such as shafts, discs, sleeves, and sleeves.

The method of cutting a workpiece on a lathe known as turning involves rotating the workpiece relative to the cutting tool while the piece is being cut. The primary source of cutting energy for turning operations comes from robotic components rather than tools. Turning is the most fundamental and widespread method of cutting CNC milling part, and it plays an extremely important role in the production process. The machining of the rotating surfaces of robot parts can be accomplished through turning. Turning methods are able to process the majority of mechanical parts that have rotating surfaces, such as inner and outer cylindrical surfaces, inner and outer conical surfaces, end faces, grooves, threads, and rotary forming surfaces. Other processing methods include milling and drilling. The majority of the tools that are used are turning tools.
Lathes are the most widely used and the most commonly used process for processing robot parts, accounting for approximately 50% of the total number of machine tools. This is because lathes are the most common type of machine tool that is designed to cut metal. In addition to being able to turn the workpiece with turning tools, the lathe also has the capability of using drills, reamers, taps, and knurling tools for drilling, reaming, tapping, and knurling respectively.

2. Milling

Milling is the process of securing the blank and then using a milling cutter that rotates at a high speed to run on the blank while it is fixed in order to cut out the desired shape and features of the robot part. Machining of complex shapes and features can be accomplished by CNC milling machines, whereas traditional milling is typically used for milling relatively straightforward features and contours such as slots and contours.

A rotary tool for milling machining that can have one or more teeth is referred to as a milling cutter. During operation, the allowance of the workpiece is removed from each cutter tooth in turn, which occurs intermittently. On milling machines, milling cutters are most commonly utilized for the purposes of machining planes, steps, grooves, forming surfaces, and cutting off robot parts. Milling is a widespread CNC parts practice in the field of cold metal processing. In milling, as opposed to turning, the tool rotates at a high speed under the drive of the spindle, while the precision parts to be machined remain relatively still. This is the primary distinction between the two processes.

3. Planing

Planing is a cutting method that involves the use of a planer to carry out a horizontal relative linear reciprocating motion on robot parts. This method is utilized primarily for the purpose of modifying the shape of robot parts. The accuracy of the planing processing is between IT9 and IT7, and the surface roughness Ra is between 6.3 and 1.6um.

Components of the planing motion include the main cutting motion, which is characterized by the linear reciprocating motion of the workpiece, and the feeding motion, which is characterized by the linear intermittent motion of the tool. Low productivity can be attributed to the fact that there is a return idle path in the main motion of planing and that the reciprocating motion cannot be performed at a high speed. Because of the characteristics of planing, it is most commonly utilized in single-item and small-batch production, as well as in maintenance and mold workshops. In addition, planing is widely utilized in mold workshops.

Planing is primarily utilized for the processing of planes, which can include horizontal, vertical, or inclined surfaces. Planing is also widely utilized for the CNC machining of straight grooves, including right-angle grooves, dovetail grooves, and T-shaped grooves, amongst other types of grooves. It is also possible to use it to process racks, gears, splines, and forming surfaces with straight lines if the appropriate adjustments and addition of certain accessories are made.

4. Grinding

Grinding is a method of processing that involves removing excess material from a workpiece by means of abrasives and tools that are themselves abrasive. Grinding is one of the most commonly used cutting methods for various types of robot parts.

Grinding is an abrasive cutting process that involves processing the surface of a workpiece with an abrasive tool such as a high-speed rotating grinding wheel. Grinding is a cutting process. Grinding is used to machine special and complex forming surfaces like threads, gears, and splines in addition to the inner and outer steel CNC machining cylindrical surfaces, conical surfaces, and flat surfaces of a variety of workpieces. The high hardness of the abrasive grains allows the abrasive tool to sharpen itself, and grinding can be used to process a wide variety of materials. These materials include hardened steel, high-strength alloy steel, carbide, glass, ceramics, marble, and other high-hardness metals and non-ferrous metals. metallic material.
Grinding is typically used for semi-finishing and finishing; its accuracy can reach IT85 or even higher; the surface roughness is typically within the range of 1.25 to 0.16 microns; precision grinding achieves surface roughness within the range of 0.16 to 0.04 microns; and ultra-precision grinding achieves surface roughness within the range of 0.16 to 0.04 microns. Grinding has a Ra range of 0.04-0.01 micron, and mirror grinding can achieve Ra values as low as 0.01-0.01 micron. Huiwen Zhizao has been dedicated for a long time to the processing of high-precision, high-difficulty, and easily deformed metal and plastic parts, as well as the production of light alloy and composite parts in small and medium batches, and the provision of robot parts procurement and customization services.

5. machining center controlled by a CNC

A CNC machining center is a type of CNC machining machine that possesses all of the capabilities of other CNC machines. Milling, boring, drilling, tapping, and thread cutting are all done with a single piece of equipment thanks to this feature, which gives the machine a wide range of technological capabilities. The CNC machining center is outfitted with a tool magazine that stores a variety of tools or inspection tools in varying quantities. These tools can be automatically selected and replaced by the program as the processing progresses.

The CNC machining center possesses powerful capabilities for performing comprehensive processing. When the workpiece is clamped all at once, it is able to complete a greater number of processing contents while maintaining a high level of processing accuracy. Its efficiency is five to ten times higher than that of conventional equipment, particularly for batch processing of workpieces with moderate processing difficulty. It is more suitable for single-piece processing or medium- and small-batch multi-variety production with complex shapes and high precision requirements, and it is able to complete many processing tasks that standard equipment is unable to complete.
