Advanced Spindle Technology
The built-in spindle design reduces centrifugal force effect and restrains spindle vibration,
which increases the spindle life span and improves long-term machining accuracy.
Built-in motor spindle on front and back spindles
Built-in motors are extremely compact and achieve maximum rigidity, a requirement for achieving maximum speeds and exact concentricity.
Built-in motor spindle have high power up to high speed and maintain high precision and low vibration all in one simple mechanical structure.
Built-in main and back spindle motors increase tooling accuracy.
Precision High Responsive Temperature Control with oil cooler: each motorized spindle is equipped with an internal and external temperature sensor.
Circulating oil cooling: The cooling circulating channel is used to cool the spindle in order to keep its temperature within a certain range and ensure the service life and axial accuracy of the spindle.
High dynamic rotation accuracy =
High gloss effect result + good surface machining quality = good surface texture.
High static rotation accuracy =
The end face run-out of the shaft end of the motorized spindle and the run-out in the taper hole are ≤0.003mm
The vibration of the spindle is ≤0.8mm/s.
Water Cooled spindle Motors
Build in spindles with constant temperature control
The spindle really is the heart of the machine and is designed with the application and user specifications in mind. Regardless of what type of machine you are running, the spindle allows the machine to function. Water cooling increases the spindle life drasticaly, keep the high precision tolerances of the machining within strict tolerances and reduce maintenance costs .
Hybrid Guide Bush
Convertible to Chucker in Minutes
The flexibility of the Swisstek Series is enhanced by its ability to switch between Guide Bush Mode (Swiss type) and Non Guide Bush Mode. With the rough material chucking option, a user can easily convert the SwissTek series to run without the guide bushing. For parts with less overhang (machining length less than 3 times the bar diameter ), the rough material chucking option allows the main spindle to extend into the cutting area.
This added capability lowers running costs by leaving a shorter bar remnant and allowing the use of less expensive non-ground bar
Changing from one configuration to another only takes minutes, allowing the user to choose to run the machine either with or without guide bushing as the needs change. A special interfacing mechanical design of guide bush can be mounted or dismounted based on the actual situation. It is more flexible in use and save cost on facility and space in the factory.
With Guide Bush | Without Guide Bush |
| Suitable for long bar work-piece: increased precision | Suitable for short workpieces : reduced losses |
Convert to chucker mode in minutes
With the increase in material cost in recent years, it’s great that SwissTek Series have chucker mode to reduce waste. In chucker mode, the machine doesn’t require the space between the guide bushing and the collet so there is less bar remnant. Chucker mode does not require the use of ground bar stocks, so it is suitable for cheaper cold-drawn bar machining.
In addition, the powerful chucking force enables heavy cutting, minimizes roughness and improves roundness. The user can choose between guide bushing mode or chucker mode according to the length of the part to be produced and be able to convert to chucker mode in minute
Swiss-type CNC screw machines
Like other kinds of lathes, a Swiss-type CNC screw machine allows workers to cut, drill, or otherwise manipulate a workpiece along an axis of rotation in order to guarantee symmetry along that axis. It gets its name from the region it was originally invented in, as Swiss watchmakers initially used them to make the tiny screws for clocks, which helped cement their reputation for making the best timepieces on the entire planet. Today, a Swiss-type CNC, also known as a Swiss Screw Machine, is a type of lathe that is perfect for manufacturing a huge range of parts and pieces.
The Difference
The quality that makes a Swiss CNC screw machine unique from other machines is that it provides material with additional support through what’s called a guide-bushing. The guide-bushing is fitted around the material and prevents a large amount of the bar stock being exposed, which provides rigidity and allows the machine to hold a tight tolerance better than other kinds of lathes.
The Wide Range of Possibilities
While the name Swiss screw machine implies that it is only useful for making screws or other threaded parts, there is actually a wide range of projects and parts that this machine is capable of making. Because of the rigidity and support that the machine provides, turned parts that are long, slender, and detailed are particularly well-suited to being made by a Swiss-type lathe. Of course, Swiss screw machines aren’t only limited to the small and slender. All kinds of parts can be machined on them, to the point where the all major manufacturers in the defense, medical, and aerospace industries rely on Swiss-Type CNC Screw Machines to make many of the parts that their complicated designs include.
A Swiss CNC screw machine is a fantastic addition to any manufacturing floor.
Difference for your parts when using a guide bush or not
Easy removable coolant tank and chip conveyor for cleaning - Independant from Machine
No thermal contact with coolant and Machine bed : Thermal much more stable production.
Why using a Swiss Style Lathe?
A Swiss Lathe is a type of lathe whereby the holding mechanism or collet is recessed behind the guide bushing. The Swiss lathes are also commonly known as Swiss screw machines, Swiss automatic lathes or Swiss turning centers. The Swiss lathe differ from the traditional lathes in the way that the holding mechanism or collet that holds a bar stock will not be exposed directly to the lathe bed and the tooling. This particular configuration provides this specific machine tool a number of benefits over the traditional type lathes.
The advantages of the Swiss lathe over traditional lathes are largely due to the fact that it utilizes guide bushing. The guide bushing purpose is to offer an additional support to stock material when the part is machined or turned. This guide bushing is fitted closely yet not tightly to surround the bar-stock materials.
The support of this bar-stock material means that the functions of the guide bushing act in a similar fashion as steady-rest does on carriages of traditional lathes.
The Swiss-style lathes typically hold a better tolerance on the parts as turning operations will be conducted closely to the guide bushing.
The guide bushing offers rigidity to turned parts due to the fact that a very small amount of the stock will be exposed once they have left the bushing and until such stage that the turning tools have been engaged.
The guide bushing offers significant rigidity to the stock and these machine types are significantly well-adapted to holding a tight tolerance.
Another benefit of the abilities of the Swiss-style lathe is that they have the abilities to turn the small-diameter parts. Alternatively, they can turn parts that have a larger length-to-diameter ratio. Chatter of tools is also minimized due to the guide or tool bushing position.
