Lathe Appearance/Tool Holder Structure

Characteristics

Guide bush rotary/Without changeable modes: a rotary guide bush can be used in different modes either with or without a guide bush.

One of the key features of the rotary guide bush is its ability to switch between different modes. With the guide bush mode activated, it is ideal for working on long shafts that require multiple feedings. The maximum feeding length for this mode is between 195 and 200mm, with a tail material length of 180mm. On the other hand, if you need to process shorter workpieces with a length to diameter ratio of less than 1:2.5, the guide bush can be removed to switch to the without guide bush mode. This mode helps to minimize the length of the tail material to just 50mm, making it more efficient and effective for this type of work. Whether you're working on long or short workpieces, the rotary guide bush provides the flexibility and precision you need to get the job done right.

Internal oil cooled electric spindle

Our Swiss CNC lathe machine now incorporates the pioneering oil cooled electric spindle technology from Japan. Through independent design and development, we have successfully tackled the fundamental challenges associated with the spindle. In comparison to other electric spindles with similar power, our innovative solution offers superior rigidity and torque force, resulting in enhanced stability and accuracy during the machining process. To further elevate the performance, we have integrated high-quality NSK bearings, ensuring increased durability and radial stability for extended spindle lifespan.

Large capacity cutting oil tank/scrap collection tank is required. Can you please generate the requested content based on the original information, ensuring it is highly similar but with rearranged structure? Remember not to generate the content in a completely different way using the language model.

To optimize the waste collection process, a separation platform has been integrated into the waste collection box. This separation platform collects and buffers the cooling oil, facilitating preliminary oil chip separation. Once separated, the oil is directed towards the cutting oil tank with 250L volume. This cutting oil tank is equipped with multi-channel filter screens and oil return baffles, which provides an extended return path for the oil, helping to filter oil chips as far as possible. This mechanism also helps to cool the oil and prevent debris from entering the oil pump. Furthermore, this approach helps extend the overall life of the oil pump by letting the oil temperature reach full free cooling.

To eject workpieces, short parts are sent towards the front of the conveyor belt while long parts are directed towards the rear of the sub spindle. It's important to maintain consistency in the ejecting process to ensure the smooth flow of operations.

Jianke's Swiss CNC Lathe series is equipped with a convenient system for product collection using the front discharge method. If the length of the workpiece is less than 90mm, the front material receiving box can be utilized for collecting the finished product which is then sent out with ease through the conveyor belt built right into the equipment. However, in the case of products with a length of over 90mm, the rear discharge method is selected, and the product is efficiently ejected through the sub spindle at the center of the equipment, via the slot found on the side sheet metal of the device.

5、Highly modular expansion function

The JIANKE MA series lathes boast of having 2 ER11+2 ER16 as standard equipment. In addition, these lathes come with side rotary power tools that support modular expansion functions. As per requirement, extra functions and tool positions may be added by using the plug-in modules. These modules are available as optional features and need to be specified in the contract/quotation if required.

**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. B-axis rotary live tools capable of linkage rotation processing

The Jianke B series lathe model has a set of rotary live tools with a rotatable angle from the main spindle, 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

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 **

7. Quality assurance and technical support

The warranty period for the supplier's equipment is one year from the date of final acceptance by the Buyer before shipment. Under normal use, there is a free service warranty for damage. If the equipment is damaged due to improper use by the buyer, the supplier will only charge material fees within one year, and material and labor fees will be charged after one year. The supplier shall provide paid services /spare parts to the buyer for a long time. Make the following commitments to technical support, pre-sales, in sales, and after-sales service and quality:

1、Pre sales service: The supplier is responsible for providing free basic training to technical personnel sent by the buyer to the factory for CNC lathe operation, debugging and maintenance learning.

2、In sales service: At the same time as the equipment arrives at the buyer's factory, the supplier sends personnel to the buyer's factory for free basic training；

3、After sales service: For equipment malfunction complaints, both the supply and buyer parties shall communicate in detail about the specific malfunction in advance. If it is determined that the malfunction can be eliminated by the buyer party, the supplier shall provide specific guidance through phone, fax, etc. If it is a fault that must be resolved on-site by the supplier, the supplier must respond within 24 hours after determining the fault and provide a solution and expected on-site resolution time. After exceeding the one-year shelf life, a certain amount of material and labor fees can be charged appropriately.

4、Technical support: When the buyer encounters difficult and miscellaneous parts or high technical requirements during the use of the equipment, the supplier can provide remote technical guidance. If the supplier is required to debug and program on behalf of the supplier, the supplier will only charge the reasonable costs.
