Abstract
Abstract A method for making a first object (1) which can be fixed with great precision with respect to a second object (2) comprises the steps of pressure-casting the first object from a plastically deformable, relatively soft metal such as light metals and zinc alloys, sizing the first object (1) at least in the area of desired surfaces (12, 13, 14) of contact between the first object (1) and the second object (2) by pressing the first object (1) into a sizing tool which consists of a hard material and has in the area of the contact surfaces (12 to 14) a negative form with respect to the desired form of the first object (1), the first object (1) undergoing a plastic deformation at least in the area of the contact surfaces (12 to 14). The additional step is performed of applying a relatively hard metal surface coating to the first object (1) at least in the area of the contact surfaces (12 to 14) (FIG. 1 ).

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
131 words
A method of manufacturing a pallet including at least one resilient centering tenon having contact surfaces to be engaged in stiff, non-resilient walls of a groove of a machine table for fixing the pallet in a predetermined position relative to the machine table, the method comprising the steps of pressure casting a pallet from a plastically deformable light metal selected from the group consisting of aluminum, aluminum alloy, brass, and zinc alloy to obtain a cast pallet with a centering tenon having contact surfaces, and then pressing at least a centering tenon of said cast pallet obtained in said casting step into a sizing tool which plastically deforms the centering tenon at least on an area of the contact surfaces thereof so that at least said area is sized and solidified.
Claim 2
Independent Claim
131 words
A method of manufacturing a pallet including at least one resilient centering tenon having contact surfaces to be engaged in stiff, non-resilient walls of a groove of a machine table for fixing the pallet in a predetermined position relative to the machine table, the method comprising the steps of pressure casting a pallet from a plastically deformable light metal selected from the group consisting of aluminum, aluminum alloy, brass, and zinc alloy to obtain a cast pallet with a centering tenon having contact surfaces, and then pressing at least a centering tenon of said cast pallet obtained in said casting step into a sizing tool which plastically deforms the centering tenon at least on an area of the contact surfaces thereof so that at least said area is sized and solidified.
Claim 3
Dependent Claim
25 words
The method of manufacturing a pallet according to claim 1, further comprising a step of providing at least said area with a hard surface coating.
Claim 4
Dependent Claim
24 words
The method of manufacturing a pallet according to claim 1, wherein said sizing tool is made of a material harder than said light metal.
Claim 5
Dependent Claim
21 words
The method of manufacturing a pallet according to claim 2, wherein said step of providing is performed before said pressing step.
Claim 6
Dependent Claim
21 words
The method of manufacturing a pallet according to claim 2, wherein said step of providing is performed after said pressing step.
Claim 7
Dependent Claim
28 words
The method of manufacturing a pallet according to claim 2, wherein in said casting step said pallet is cast with an accuracy of about 10 to 50 μm.
Claim 8
Dependent Claim
27 words
The method of manufacturing a pallet according to claim 6, wherein in said pressing step the pallet is sized with an accuracy between 1 to 5 μm.
Claim 9
Dependent Claim
148 words
Method of manufacturing a pallet including a plurality of centering tenons disposed on one plane and offset at uniform angles from one another in the plane and having contact surfaces to be engaged in grooves provided in a support and likewise disposed in the plane and offset at uniform angles from each other, for fixing the pallet in a predetermined position relative to the support, the method comprising the steps of pressure casting a pallet from a plastically deformable light metal selected from the group consisting of aluminum, aluminum alloy, brass, and zinc alloy to obtain a cast pallet with a plurality of centering tenons having contact surfaces; and then pressing at least centering tenons of said cast pallet into a sizing tool which plastically deforms the centering tenons at least in areas of the contact surfaces thereof so that at least said areas are sized and solidified.
