Requirements for supply of drawings to Lincoln Binns Ltd
Data for milling of holes can be supplied in paper sketch or drawing form or as a dxf format computer file. Our cnc milling machine recognizes the bottom left hand corner of its table as the origin. This translates to the bottom left corner of the object as viewed on the computer screen or paper drawing. Drawings or dxf files must be supplied with the box or end plate in the correct orientation relative to this origin, and dimensions (not required for dxf files) must be from this point.
The correct orientation for an end plate is with its centre line vertical and the screw holes offset towards the top of the page (end plates A, B and C) or with the central extra screw hole towards the bottom of the page (end plate D). The origin for these plates will be where the left and bottom edges intersect. This is actually just off the edge of the end plate because the corner is radiused. The screw holes are already in the end plates and do not need to be provided as part of the information for the dxf or drawing, other than they help confirm the orientation of the end plate, similarly, on a sketch, a simple rectangular representation of an end plate will suffice.
The correct orientation for a box section extrusion is achieved by placing the extrusion with open end on the desk in front of you and the face to be milled towards you. The bottom left corner of the front face as you view it is the origin, and the extrusion will be represented on the drawing or computer screen as a simple rectangle. You must specify which of the two faces the drawing represents - ribbed or plain. We cannot mill holes in the dovetail sides of the extrusions.
If you want to supply us with a CAD drawing in dxf format the easiest way to start is to download the appropriate end plate dxf from our website, add the required holes (in a different colour, preferably black), and email it back to us.
Here are the downloads:
This is what the dxf download of end plate C will look like:
We have a variety of CAD programs including Solidworks so we should be able to open most formats
