Characteristics

Guide bush and changeable modes are two different options available for rotary applications.
The rotary guide bush is a component that provides support and guidance to the workpiece during machining. It helps to maintain precision and stability during the rotary motion. This type of guide bush is fixed, meaning it remains in place throughout the machining process.
On the other hand, without guide bush changeable modes allow for flexibility in machining. In this mode, the guide bush is not used, and the workpiece is held directly by the rotary device. This provides more freedom in terms of the workpiece length and allows for the use of different types of workpieces without having to change the guide bush.
Both options have their advantages and disadvantages. The rotary guide bush offers improved precision and stability but limits the workpiece length and requires changing the guide bush when working with different types of workpieces. On the other hand, without the guide bush, changeable modes offer more flexibility but may sacrifice some precision and stability.
The choice between these options depends on the specific requirements of the machining process. Factors such as workpiece length, precision demands, and the need for flexibility should be considered when deciding which option to use.

The Rotary Guide bush provides excellent support for different modes of operation. In the rotary guide bush mode, it is specifically designed for processing shaft workpieces. With a feeding length ranging from 195 to 200mm, it allows for efficient and precise machining. Moreover, it offers the flexibility of multiple feeding options. The tail material length is optimized at 180mm, ensuring effective processing.
On the other hand, the without guide bush mode is ideal for handling shorter workpieces. It is specifically designed for workpieces with a length to diameter ratio of less than 1:2.5. This mode ensures minimal tail material length, enhancing efficiency and reducing waste. The tail length is set at 50mm, enabling precision and accuracy while processing these shorter workpieces.
By offering these interchangeable modes, the rotary guide bush provides versatility and adaptability to different machining needs. It guarantees optimal performance and maximizes productivity, no matter the type of workpiece being processed.

Internal oil cooled electric spindle

Our Swiss CNC lathe machine's spindle is equipped with exceptional oil-cooled electric spindle technology, brought over from Japan, which we have extensively studied and developed. Through our ingenuity and expertise, we have successfully overcome the vital issues related to the spindle. When compared to rival electric spindles with equivalent power, our creation possesses greater rigidity and torque force with highly reliable processing accuracy. For maximum longevity and radial stability, we opted to utilize NSK bearings, ensuring that our product delivers long-lasting durability that surpasses industry standards.

A cutting oil tank with a large capacity that can collect scrap is available. To produce a comparable content, the original text information should be rephrased and presented differently.

The waste collection box is designed with a chip collection platform that separates the cooling oil from the chips. This platform helps to provide preliminary buffering and cooling, which ensures effective oil chip separation. The cooled oil then flows into a 250L cutting oil tank. This cutting oil tank is fitted with multiple filter screens and oil return baffles that are used to extend the return path of the oil. These mechanisms further separate and filter the oil chips as much as possible, ensuring the oil temperature reaches optimum levels for free cooling. By doing this, it reduces the debris that enters the oil pump and prolongs its service life.

The workpiece ejection method involves the front ejection of short parts on the conveyor belt, while the rear ejection of long parts is facilitated by the sub spindle. The goal is to ensure efficient handling and management of workpieces based on their size and dimensions. By implementing this approach, the workflow can be optimized, allowing for smooth operations and seamless transitions during the manufacturing process.

Jianke's complete range of dual spindle Swiss CNC lathes are equipped with a front discharge product collection method as a standard feature. The front material receiving box is used for collection when the workpiece length is less than 90mm, and the products are sent out through a built-in conveyor belt. If the product length is more than 90mm, the rear discharge method can be selected, and the product is ejected through the center of the sub spindle via a slot on the side sheet metal of the equipment. To summarize, Jianke's dual spindle Swiss CNC lathes come with a variety of product collection and discharge methods depending on the size of the workpiece.

5、Powerful sixth axis tool holder

JIANKE has developed an innovative, patented structure for the latest model of their S series, featuring six axes. This cutting-edge design is the result of JIANKE's independent research and development efforts.（Patent NO. ZL202220166953.5）

Turning tools：●The regular six axis standard configuration does not have a turning tool position, and the O.D. turning processing can only be achieved by installing O.D. turning tool carbide inserts on the boring tool shank, which has poor rigidity.

▲S series six axis lathe equipped with 2*12×12 square tool shank，stronger enough to turning O.D.

Side milling tools：●The regular six axis lathe standard configuration does not have a side rotary tools and needs to be expanded through plug-in modules. The plug-in modules can only be 1 potion hole with 1 rotary tool and the price is expensive.

▲The S series six axis lathe comes standard with 4 ER16 side rotary tools. If there are not enough positions, it could expand 3 side rotary tools by occupying 1 position of ER16, achieving a maximum of 6 side rotary live tools; At the same time, the tool direction is milled from top to bottom, which has stronger milling rigidity than the side milling rotary tools.

End face milling：●The regular six axis lathe comes standard with four end face rotary tools, which cannot be extended for more end milling tools. If there are requirements which need functions expanded, it will occupy the end face rotary tools position which cause shortage of end face rotary tools.

▲The S series six axis lathe is equipped with 3* ER16 end face rotary tools as standard. If there are not enough positions, it could expand three end face rotary tools by occupying one side rotary tool position, achieving a maximum of six end face rotary tools.

6. Highly modular expansion function（Patent NO.ZL202220166953.5）

The MA series lathes are standard equipped with 2*ER11 +2*ER16 rotary tools of the main spindle, the2* ER16 rotary tools able to use plug-in modules.

The MA25-6S model lathe, both the main spindle side rotary tools and sub spindle rotary tools could achieve

plug-in expansion modules.

（Plug-in modules are all options，if needed , please list them in the contract/quotation）

**The above is only a demonstration of the plug type expansion functions of some modules.Please confirm with JIANKE if you have more requirements of other modules based on actual processing**

6.Swiss CNC lathe requirements for raw materials in the processing of long bar materials.

1、Recommended use of polished/precision drawn materials: As the standard bar feeder supports a maximum length of 3M for bars, it is recommended that the length of a single bar material should be ≤ 3M；

2、Consistency of material diameter tolerance within ± 0.02mm；

3、The consistency of material roundness tolerance is within 0.005-0.01mm；

4、The straightness of the material is required to be within 0.35mm/m；

5、All the bar materials need to be chamfered at both ends；

6、Some large-diameter materials and irregular(suquare/hexagonal) materials require to turning the tail of them to match the bar feeder collet and easy to be sent through the spindle hole；

7、When the material hardness is higher than HRC28 degrees, a prior declaration is required。

** The above are the regular requirements of raw materials for the Swiss CNC lathe, and the material tolerance can be relaxed/tightened according to the actual product accuracy requirements **
