FULL DESCRIPTION OF LATHE VENUS 350
The numerically controlled lathe Venus 350 is a modern, precise and at the same time a highly efficient machine tool, designed according to the latest trends in the construction of machines of this class. Important elements affecting the technical and operational parameters of the machine include:
Based on many years of experience in the field of machine tool design testing, AFM has developed an optimal angle of bed inclination, on the one hand guaranteeing the proper rigidity of the machine tool, and on the other hand good chip flow and relatively small dimensions of this class of machine.
The designer designed one common bed for the Venus family of lathe chuck-chuck, a chuck-rod version without tailstock. As a result, AFM is more flexible in adapting the final machine configuration to the actual needs of the customer.
Main lathe assemblies:
The headstock is not one cast screwed directly to the lathe bed as in traditional lathes, but consists of two bodies that allow a mutual partial compensation of thermal deformations resulting from the heating of the machine tool during cutting – this is the so-called “Hammock spindle suspension”, thanks to which it is possible to work the machine very accurately without a preheating period, immediately after starting.
The tailstock is moved by a hydraulic cylinder on non-playable rolling guides. In the upper part of the body, i.e. the head, there is a permanent rotary tuck built-in, or the sleeve ends with a Morse socket. This solution of the tailstock allows you to control its travel along the entire length both with a pedal and also fully automatically through CNC control.
In place of the tailstock, on the same guides, a capturing headstock can be built-in, which, in conjunction with the radial head, enables the workpiece to be machined from two sides.
The version of the machine with a capturing headstock requires the use of a tool head that allows radial clamping of left and right tools allowing machining of the workpiece both in the main and capturing headstock.
The carriage and cross slide have a rigid structure and are guided on rolling guides with preload. Adequately wide track spacing ensures bottom bracket stability and system rigidity in working conditions. In the special machine version, we mount the transverse support drawer on a prism at an angle of 300 to the lathe bed. By adding an additional drawer shift in the “X2” axis from a combination of “X1” and “X2” axis movements, we are able to obtain a carriage movement in the “Y” axis in the +/- 40mm range.
Tool System – in the basic version it is equipped with a 12-position tool head with direct clamping of 20×20 turning tools. Internal machining tools are clamped in the clamps around the circumference of the head disk. At the customer’s request, the tool system can be equipped with a head adapted for axial attachment of tools in all positions in standard VDI 30 holders. For machine versions with the “C” axis and driven tools, we always use heads with the VDI clamping system. In each case, the coolant is fed through the head disk and/or tool directly to the cutting area.
We recommend the use of a fast 12-position head with rotary tools for the version of the machine with a capturing headstock. The hydraulically released head tool disk allows radial clamping of tool holders with a VDI 30 shank. The disk allows the attachment of right and left tools, which enables machining of the workpiece mounted in the main and capturing headstock. A rotary tool can be mounted in each of the head sockets. The coolant is fed directly into the cutting zone via a tool disc and/or tool.
The lathe spindle is driven by a motor with infinitely variable speed control. The torque on the spindle guarantees standard machining of maximum turning diameters.
In the version of the lathe with controlled axis “C” and the head with rotary tools, the spindle drive has the possibility of precise angular positioning of the spindle, and the brake mounted on the spindle allows the elimination of spindle creep during milling or transverse or misalignment drilling operations.
To control Venus 350 lathes we use modern CNC control systems cooperating with digital drive systems with high dynamics and reliability. The choice of the customer depends on the use of one of the following systems:
We offer Fanuc and Siemens control systems together with Manual Guide or Shop-Turn software – a dialog programming aid, thanks to which programs can be created directly on the machine’s desktop without having to learn traditional programming.
Both Fanuc and Siemens control systems are equipped with a visual simulation of the machining process, clearly displayed on the colored control screen.
In addition, a control system simulator can be installed on the PC, configured in the same way as the system on the machine tool.
The control system can be connected as standard to the internal Ethernet network, which facilitates the management of technological programs, as well as allows remote diagnostics of the machine via the Internet.
When using simplified controls, we must take into account the limitation of control functionality. Simplified control versions do not have:
- 3D simulation
- Dialogue programming support (Manual Guide or Shop-Turn)
- Can be used for a simple – maximum 3-axis lathe (they do not support the machine version with interceptor and the “Y” axis).
