Nowadays, CNC turning machines are divided into two categories according to the way of clamping work pieces and the spindle arrangement, namely vertical lathes and horizontal lathes. The CNC oil country lathes belong to horizontal model because most of the work pieces are too large to be loaded on a vertical platform. In the vertical lathes, the work piece is clamped vertically, and the cutting tools are installed in the same direction connected to the spindle, so that the CNC machining proceeds in the vertical direction.
Compared with CNC horizontal lathes, due to the gravity effect, the vertically clamped work piece arrangement will be firmer and better fixed. Manufacturers of vertical turning machines usually turn it into high precision and high quality production equipment, which is used in automotive industry, aerospace, sports equipment manufacturing, and some larger work pieces are not suitable for heavy duty turning lathes, such as CNC oil country lathes with highly efficient spindles.
There is no invincible system that wins everything. In the vertical clamping mechanism, the spindle of the vertical turning lathes is located behind the chuck, which may cause the vertical arrangement of the chuck and the cylinder on the base case to bear too much gravity. The lathe spindle of CNC machines may be belt driven, or other types of driving methods. Driving powers of spindles can be designed based on the CNC lathes’ types.
Similar to other CNC milling machines and CNC machining centers, CNC turning lathes can also be equipped with power tools and tool magazines to improve their functionality and versatility and provide users with greater processing possibilities. The power turret is a modern standard accessory for many CNC turning machines and one of the most important accessories for users of CNC lathes. Taiwanese suppliers have aimed at this business and developed many high quality power turret and power tool products to support the needs of lathes’ users from different sectors around the world. Lathes are now very versatile compared to the past times.
These components and accessories bring great convenience to users. In the past decade, no matter how prices change, demand has surged. Many power turrets are driven by single motor with servo function, which can ensure the best processing results and save the best energy consumption. At the same time, they can also provide great rigidity to the work piece, thereby providing ideal cutting performance.
In addition to the power turret, tool magazines and automatic tool changers (ATC) are also the best selling products of Taiwan's machine tool accessory suppliers. The tool magazine and automatic tool change system made in Taiwan can provide the optimal tool to tool time according to the customer's cycle time engineering to help customers meet order requirements. Compared with global competitors, Taiwanese suppliers know how to provide customers with comprehensive services based on local conditions and upgrade machine tools and accessories to the latest version to meet various new order requirements.
Spindles, chucks and corresponding hydraulic cylinders are also very developed in Taiwan's machine tool component market. Together with CNC turning machine, there are a series of lathe products, components and accessories that are widely used in different industrial fields around the world.
Speaking of the design of heavy duty lathe machine, among the many different designs of turning machine structures, there is a very common thing, that is, the horizontal arrangement of the spinning spindle, which is used to clamp the work piece to be processed by the cutting tool.
A lathe machine is also called a turning machine. It is a machine tool that rotates a work piece on a rotating axis for cutting, knurling, sanding, drilling, deformation, facing, turning and other processing which is related to the spinning spindles. This type of machining is performed by moving the tool, which will be applied to the target work piece and create an object with an axis-symmetrical contour. By convention, the horizontal arrangement is the most common machine tool design used for heavy duty machining, because this arrangement can handle loading issues in a much easier way, thus providing a convenient machining process.
