Definitions
- the object of the present invention is to enable short series to be undertaken without having to change the machines which are engaged in long production series. This is en- abled by using milling cutters in which the blank to be machined is secured to the holder for a cutting tool and that a number of holders are placed on the milling table ⁇ provided with fixed, stationary tools.
- the holder with the blank is programmed to be carried to the various holders with stationary tools and the blank is therefore subjected to various turning operations.
- Some of the hol ⁇ ders may contain drills, thus enabling even drilling opera ⁇ tions to be executed.
- the holders ' for the various stationary tools are suitably applied on a support surface, said surface preferably being provided with two carrying handles.
- the holders on the support surface can be adjusted to certain desired positions. In this context both the holder and the tool in relation to the holder may be adjusted.
- the support surface with holders is secured to a milling table, after which machining can be effecred.
- the milling cutter may preferably consists of a CNC-program- med cutter.
- the picture shows a rotating holder (1) for a tool.
- the holder (1) forms part of a conventional milling cutter. Instead of the holder containing a cutting tool, it con ⁇ tains a blank (2) to be machined.
- a support surface in the form of a rectangular girder (4) provided at each end with a handle, (5 and 6) is placed on a milling table (3).
- the support surface (4) is designed to receive five different holders (7, 8, 9, 10, 11) for stationary tools.
- Each holder (7) is secured to the support surface by means of two screws (12 and 12) and is adjustable in transverse direction.
- Each holder (7) is provided at the top with a tool attachment (13, 14, 15, 16, 17).
- the tool attach- ent in the holder (7) furthest to the left is designed for a cutting tool (18).
- the tool (18) can be adjusted via the attachment (13), in relation to the holder (7).
- the drawing shows two more holders, (10 and 11) of the same type as the holder (7).
- the tool attachments (16, 17) for holders (10 and 11) are designed for supporting tools.
- Two more holders, (4 and 9), are also shown, each of these being provided at the further end with a chuck (19 and 20) retaining a drill (21) and a tapping tool (22).
- the tools are adjustable in relation to the holders (8 and 9).
- the device according to the present invention functions as follows: the holders (7 to 11) are secured in the de ⁇ sired positions on the support surface. Both holders and attachments are secured.
- the support surface with the holders is car ⁇ ried by the two handles (5 and 6) to a milling table (3) , where it is secured in a predetermined manner.
- the blank (2) in the holder for cutting tools can now be conrrolled in such a manner that the blank is first presented for machining a holder 7 and thereafter in turn to the tools in the holders (8, 9, 10, 11).
- the holder with the blank need not move to the holders in the order men ⁇ tioned. Different se ⁇ uences are also feasible.
