FULL DESCRIPTION OF OSA 100
Extremely compact, innovative design combined with precision
Functionality, modern numerical control system, extremely rich special equipment, and ease of automation of loading/unloading workpieces make the new Afm “OSA 100” lathe a unique offer on the machine tool market.
The use of a flat bed greatly increases the space in the machining zone, which allows the installation of various types of devices that increase the functionality of the machine while maintaining an economical level of the price of the machine.
The specificity of the machine design translates into specific benefits for the user:
- Enables machining with a greater number of different tools than when using a standard tool head.
- Tool change is usually faster than with a tool head.
- Faster and easier machine changeover when changing the workpiece.
- Low-cost solution for machining with driven tools such as milling or cross-drilling.
- Possibility of machining on the other hand using a manipulator that rotates the part.
- The possibility of easy and cheap automation of loading and receiving workpiece.
The simple design of the linear support allows for economical composition of interesting sets of tools and special devices enabling the implementation of very advanced technological operations without the need to purchase complicated and expensive options for standard CNC lathes. Below we show some noteworthy solutions that significantly increase the machine’s usability:
Undoubtedly, the first setting of a set of knife clamps with tools for processing a selected detail is more time consuming than setting up a standard tool head in a classic CNC lathe. In the OSA lathe, we offer replaceable tool strips on which we can mount ready-made tool sets for specific details. Converting a machine for the production of another workpiece boils down to merely replacing a tool bar with a ready set of pre-set tools and selecting another technological program from the memory of the control system. In this mode, the changeover time can be much shorter than in the case of a classic lathe with a tool head.
Considering the arrangement of the linear support in relation to the lathe spindle, both for machining holes and external surfaces we can use boring tools.
The use of right and left handles alternately gives the opportunity to optimize the use of space on the cross slide, which in turn increases the number of tools that can be used.
With small diameters of the peeled detail and many internal operations, it is a good solution to use a composite holder, which with a small size houses as many as four tools. By using several boring tools for external machining, alternating the use of right and left tools, e.g. for roughing and finishing, we have the chance to minimize the times of changeover movements when changing the tool cannot be achieved with the use of a classic revolver tool head.
Regardless of the above holders, we also offer classic right and left cross holders for knives with a 16x16mm diameter. These are the frames of our production, so they come into play all their modifications allowing to achieve the effect desired by the customer.
The machine is prepared to work with a rod up to 32 mm in diameter. Regardless of the possibility of using any bar feeders available on the market, we offer our proprietary simplified solution. A set of straight bar guide cooperating with a special holder – “bar puller”. The task of the bar guide is only to guide the bar in a ball-bearing guide tube lined with a Teflon reducing sleeve.
The bar feeding process is carried out using a bar ‘puller’
A special tool holder that ‘grips’ the bar, after releasing the grip clamp with feed in the ‘Z’ axis the carriage pulls the rod to the given size, the grip clamps again and the holder retracts and releases the clamp rod.
A very interesting advantage of the OSA 100 lathe may be its structural preparation for building automatic parts loading. The simplest, but at the same time very effective solution is the gravitational part feeding system and their loading into the holder using a pneumatic manipulator. The part placed in the feeding chute, properly angularly oriented, is gripped by a pneumatic manipulator mounted on the tool carrier and placed in the handle by means of the “X” and “Z” axis movements. Using the “C” axis for the proper orientation of the spindle, we can also specify non-circular details – eg hexagonal or square.
At the end of all operations, the part can be “picked up” by the detail catcher, which directs it to the machined workpiece basket, eliminating the need to select details from chips.
