The rotary guide bush and the without guide bush changeable modes are two distinct options that are available for machining. By rearranging the initial text, a highly similar content could be generated:
In the world of machining, there are two options available when it comes to rotary tools: the rotary guide bush and the without guide bush changeable modes. These are two distinct ways of approaching the machining process, each with its own benefits and drawbacks. Those looking to optimize their machining processes should investigate each option thoroughly to determine which one is best suited to their individual needs.

The Rotary Guide bush is an excellent support for both the rotary guide bush mode and the mode without guide bush. In the rotary guide bush mode, it is specifically designed for processing shaft workpieces. It allows for a single feeding length of 150mm and provides the option for multiple feeding. Additionally, it ensures greater stability and precision during the machining process. The tail material length is kept at 220mm, offering ample support.
On the other hand, the mode without guide bush is perfect for processing shorter workpieces with a length to diameter ratio of less than 1:2.5. This mode is particularly advantageous as it helps minimize the length of the tail material. With this mode, the length of the tail is reduced to just 70mm, allowing for more efficient and precise machining of shorter workpieces.
Both modes of the Rotary Guide bush offer unique benefits depending on the type of workpiece being processed. Whether it's a shaft workpiece or a shorter one with specific length requirements, this versatile tool provides excellent support and flexibility to meet various machining needs.

Internal oil cooled electric spindle

Our Swiss CNC lathe machine now boasts independently designed and developed electric spindles utilizing Japan oil cooling technology. By overcoming the core issues that previously plagued our spindles, we have created a product with unrivaled rigidity, torque force, and processing accuracy. We chose to use NSK bearings to extend the life of our spindles while also ensuring radial stability. It is safe to say that our new spindles are a game-changer in the industry.

Large capacity cutting oil tank/scrap collection tank.

The waste collection box has been designed with a separating platform to collect chips, which allows the cooling oil to undergo preliminary buffering and cooling. This feature ensures that the oil is separated from the chips before entering the cutting oil tank. The tank has a capacity of 340L, and is equipped with multiple filter screens and oil return baffles to ensure an extended return path. This advanced filtration system ensures that the oil and chips are separated as far as possible.
Using this system, the oil temperature can reach full free cooling, and the debris entering the oil pump is greatly reduced. Consequently, the service life of the oil pump is extended. Overall, the waste collection box is an advanced and efficient system that ensures the safe and effective disposal of waste, while at the same time protecting the environment.

The method of ejecting the workpiece will depend on its length. If it is a short part, it will be ejected to the front of the conveyor belt. On the other hand, if it is a long part, it will be ejected from the rear of the sub spindle. This strategy ensures that the workpiece is properly ejected and does not cause any disruptions in the manufacturing process. It is important to have a well-defined workpiece eject method to guarantee the efficiency and accuracy of the manufacturing process.

Jianke's complete range of dual spindle Swiss CNC lathes comes equipped with a front discharge product collection system as a standard feature. When the length of the workpiece is shorter than 90mm, the front material receiving box can be utilized for efficient collection, and the finished product can be smoothly conveyed out through the built-in conveyor belt. However, for workpieces longer than 90mm, the rear discharge method can be chosen. In this case, the product is effectively ejected through the center of the sub spindle via a slot located on the side sheet metal of the machinery. By offering these versatile discharge options, Jianke ensures optimal productivity and adaptability in handling different workpiece lengths.

5、Powerful sixth axis tool holder

The JIANKE S series introduces a groundbreaking innovation in the form of the six-axis new model with a patented structure. This ingenious design is the result of JIANKE's independent research and development. By reshuffling the original content, we can emphasize the uniqueness and importance of the six-axis new model of the JIANKE S series.（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 JIANKE DT38-6S lathe support to upgrade rotary tools with B axis which can achieve a linkage rotation of 0-90 °. For processes with multiple angle holes and workpieces that require B-axis linkage milling processing, one-time processing can be achieved. And according to demand, the rotary tools can be replaced with a boring cutter.

**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 **
