# How Do Cnc Swiss Machines Work

What Is Swiss Machine–The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment.

With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days.

After the war, it was gradually widely used in the manufacturing industry with the needs of development; then Taiwan, China introduced this technology and independently developed this type of equipment for different machining needs. The manufacturing of Swiss Machines China started relatively late. Due to technical closures and policy restrictions, Chinese Swiss Machines mainly relied on imports to meet machining needs before the 1990s.

With the continuous development of automation and the strong market demand, the Chinese market has emerged. A large number of powerful CNC Swiss Machine manufacturers have produced this series of machine tools in coastal Guangdong, Jiangsu Nanjing, Shandong, Liaoning, and inland Xi'an, and have achieved good market applications, filling the domestic gap.

Compared with CNC lathes, Swiss Machine has made a qualitative leap in machining efficiency and machining accuracy. Due to the use of two-axis arrangement of tools, the machining cycle time is greatly reduced. The table overlap function, the thread chip effective axis movement overlap function, and the direct spindle indexing function during secondary machining can shorten the idle time.

The chip tool has always been processed at the clamping part of the spindle and the workpiece, which ensures the constant machining accuracy. At present, the maximum machining diameter of Swiss Machine on the market is 32mm, which has a great advantage in the precision shaft machining market. This series of machine tools can be equipped with an automatic feeding device to realize fully automatic production of a single machine tool and reduce labor costs and product defect rates. It is very suitable for mass production of precision shaft parts.

**CNC swiss machines** are generally used to process small parts from bars, with large batches, many of which are formed at one time. As long as it involves bar machining, the diameter should not exceed 20. The advantage of the center lathe with the feeder is great (because the center lathe must be equipped with a feeder for machining), so it is a small independent production line, no matter what It is machining speed, labor cost, and he has advantages.

The main difference is: the material of the swiss machine is moving, the knife moving machine is the knife moving,

The old name of swiss machine in China should be a slitting lathe. Mainly used for holding small parts and mass machining.

Generally, the feeder passes the bar through the through hole of the main shaft, and the spring chuck is automatically clamped. If the part overhangs, it needs to be equipped with a center. If the tail needs to be processed, a second spindle is required. If it is necessary to process four and six equally divided holes, a driven tool holder and spindle indexing are required.

The swiss machine is mainly limited by the diameter of the material. Generally, the largest type of center lathe can only process parts with a diameter of 20 mm. I have only seen a center lathe that can process a diameter of 32 mm in the data. As long as it is a part that can be processed by a centering machine, its machining accuracy, machining speed, and cutting machine are difficult to compare! The main advantages are as follows:

- The spindle can turn parts with a length of more than 200mm in one clamping without stopping. If you are turning a part with a length of 5mm, you can turn the tool and the center, but you can turn 20~30 parts in one go before you need to stop and feed.
- When cutting, the center lathe will always fix the nearest position of the material, so the rigidity is very good. After you think about your lathe clamping the parts, the tool will stick to the clamping position for a few mm to turn, and the rigidity will be good. to what extent.
- The swiss machine is a combination of turning and milling, and the complexity of one-time machining and forming is not comparable to that of the old-fashioned automatic car, which is commonly known as the cam machine lathe. And now the more advanced CNC automatic lathe, we call it a center lathe or a slitting lathe. Mainly, the spindle Z moves forward and backward, and the knife can move in X and Y, which can realize three-dimensional machining and one-time forming.

Main models: RNC-V15E, RNC-V20E (turn-milling CNC swiss machine) [Machining range]: The clamping specification is Ф2mm~Ф20mm, which can be processed to a length of 700mm. The length of one feeding is 165mm, and the long product can be processed through the second time Feeding is realized, it can process smooth special-shaped materials, such as hexagonal, square, triangular and other special-shaped standard profiles, and can process stainless steel bars with hardness below HRC34 and below and difficult to process, such as copper, aluminum, easy-to-car iron, 45# steel, stainless steel : 303, 304, 314, 316, 416 and other materials, machine nylon rods and special-shaped materials. Machining function: The machine tool is fully automated from feeding to machining to receiving, and 3 to 5 machines can be processed at the same time with one operator. The row-type slitting cylindrical cutter has high reliability and fast tool change. It can be installed with 5 cylindrical cutters, 4 end face machining knives, 4 powered cutter heads, and a total of 13 knives, which can be clamped at one time: Turning pin external circle, cone, arc, curved surface, internal and external threads, cutting a slot, spiral groove, end face side drilling, boring, end face side tapping, lettering, etc. to the process.

## The Machining function Of Cnc Swiss Machine

- It is suitable for large-scale, multi-variety and high-precision machining tasks of "slender shaft" parts with relatively large length and diameter and "small" and "special-shaped" parts. Equipped with an automatic feeder to realize automatic feeding, automatic machining, and automatic feeding. This cycle will automatically alarm until the bar is processed, which truly realizes the mode of one person and multiple machines, which greatly saves labor costs.
- The standard configuration of the machine tool is equipped with 4 power milling cutters, 5 outer circular cutters, 4 end face circular cutters, one feeding process can be completed at the same time: turning outer circle, turning cone, turning ellipse, inner and outer thread, electric spindle Realize the stepless indexing function, can rotate to any angle to mill the plane you want to machine, milling plane, milling slot, spiral groove, cutting groove, side drilling, eccentric hole, tapping, lettering, knurling , and so on to the process. It saves secondary machining such as secondary milling and drilling. Improved precision and machining efficiency. Save secondary machining equipment and labor. It breaks the monotonous function of traditional machine tools that can only be turned and can only be milled.

## The Precision Of Cnc Swiss Machine

The speed range of the electric spindle is: 100~12000r/min to implement stepless speed change, the three coordinate axes of z, x and y are all controlled by high-grade servo motors, and the c-axis is the indexing of the spindle (five axes and four linkages). High-precision imported ball screw and linear guide, the radial runout of the positioning cone of the electric spindle is guaranteed to be within 0.0025mm, and the axial runout of the spindle is less than 0.0015mm. This machine tool belongs to the new generation of intelligent high-precision machining machine tools in the 21st century. . The roundness of mass production and machining is within 0.005mm, the dimensional control accuracy is guaranteed to be within 0.01mm, and the diameter (coaxiality) is within 0.004mm/100mm.
