Types of CNC Lathe for Heavy Duty
According to the earliest archeological records, the first lathe can be dated back in the Egypt in around 1300 BC, and were used for a wide variety of weaponry applications. The documentary records of lathe or rotational machinery can dates back to some Hellenistic relics as well, by which ancient craftsmen utilizes the turning mechanism to make household tools, weapons, agricultural tools, jewelry object, and other important items to be used in their daily lives and emergent cases such as fighting and war occasions.
Common feature: Horizontal design
Speaking of the design of the heavy duty lathe machine, among the many different designs of the turning machine structures, one thing is common, that is, the horizontal arrangement of the spinning spindle that clamps the work piece which is to be processes by the cutting tools. Since a lathe machine is also called a turning machine, that is a machine tool that rotates a work piece on an axis of rotation to perform various machining operations such as cutting, knurling, sanding, drilling, deformation, facing, and turning; such machining are conducted with tools that are applied to the targeted work piece and to create an object with symmetry profile with the axis. Conventionally speaking, horizontal lathe models are the most commonly utilized designs for the heavy duty tasks because the loading issues can be dealt with in a much easier way, granting convenient machining processes for operators.
CNC & Heavy duty applications
Regarding the structural design of the lathe machine, or say, turning machines, there are categories that are divided into two main types according to the way that clamp the work pieces. Those are vertical lathe and the horizontal counterparts.
For the horizontal one, work pieces are clamped on the joint of the spindle, which is driven by a power output with belt-driven, direct-driven, or in-built motors by which the model of the driven power decides most of the processing advantages.
In addition to the clamping mechanism, the hydraulic clamping force is triggered by the cylinder installed beside the spindle case for the chuck device in order to ensure the clamping force to be firmly fixed. In this way, the work piece would not go splitting up if the spinning speed is too fast, rendering unstable spinning movement. However, if the length of the work piece is too long, then there would be inevitably a straightness issue on the work piece, and there would be a tailstock at the end of the work piece to make sure the longer work piece is stabilized firmly from head to toe, making the tooling processing smooth and precise.
For the machining of heavy duty to be possible the structure of horizontal model makes the operation much easier because it is more dynamic balanced to roll those work piece components and machinery accessories on the horizontal platform than on the vertical counterparts. Furthermore, regarding the vertical type CNC heavy duty lathe machine, the work piece is clamped vertically so that the cutting tool is equipped on the same direction and the machining is conducted vertically.
Gravity issue helps in vertical models
On the other hand, though horizontal is a common model, vertical is also workable and widely accepted due to certain structural features. By this arrangement the clamping is much more stern and fixed due to the gravity effect compared to the horizontal methodology. Manufacturers of CNC vertical turning machines usually made their vertical turning machines into great manufacturing facilities for users in a variety of industrial sectors that pursue for big work piece, high precision, heavy weight demands. With the vertical clamping mechanism, the spindles of vertical turning lathes are also located behind the chuck, while some may be belt-driven, and some may be other types of driving mechanisms.
Modern machining business model requests for agile machinery and machine versatility to be the basic conditions for manufacturers. Therefore, like other milling machines and machine centers, turning lathes can also be equipped with power tools as well as tool magazines to boost its functionality and versatility, granting wider processing possibility to users in all kinds of working circumstances. Power turret is a modern and standard accessory of many CNC turning machines, and as one of the most important accessories to the users of CNC lathes, Taiwanese suppliers aim at this business and have developed many well known power turret and power tool companies that supports the demands form lathe users all over the world market.
Many of these mechanical power turrets are driven by servo motor with great torque but swift features, which can assure the best machining effects and save the optimal energy consumption. By adding the milling functionality, the capability of turning machine becomes much more competent in industrial application, rendering a great and wider variety of choices for customers and onsite operators. Even most of the heavy duty lathe machines tend to be more conventional, now the smart trend also is integrated into this field regarding the machine design, so users of the heavy duty lathe machine will also consider other smart features of the machine and its accessories while they are considering buying a new one.
