QR Code Link to This Post
This unique milling machine was manufactured by VEB Pentacon Dresden, a German company for milling the surfaces of flat, complex-shaped parts that cannot be clamped in a vice, as well as the surfaces of cylindrical parts. It is the smallest milling machine in the world, with only one copy, and is also an extremely rare collector's item.
I. MAIN COMPONENTS
- A machine bed consisting of an instrumental stand with an electrical circuit and motor speed control switch.
- Work table bracket.
- Work table.
- Drive, consisting of a 26.5V, 1A, 7000 rpm electric motor with a 1-6 mm (0.039-0.236 in) tool chuck.
- AC 26.5V, 1A power adapter.
- Flat rubber damper.
-Tool box.
II. SPECIFICATION.
- Weight: 3.7kg (8 lb 2.4 oz)
- Dimensions: Length at the base: 193 mm (7.6 in). Width at the base: 100 mm (3.9 in). Height: 275 mm (10.8 in).
- Maximum milling cutter diameter: 6 mm (0.236 in).
- Maximum tool speed: 7000 rpm.
- Work table size: 53 x 80 mm (2.087 x 3.15 in)
- Maximum dimensions of the workpiece clamped on the worktable:
width 40 mm (1.575 in); length 75 mm (2.953 in).
- Adjustable work table lift ranges from 1-16.5 mm (0.0394-0.65 in) with an accuracy of 0.5 mm (0.0197 in) using a rack and pinion mechanism.
- Adjustable tool post lowering ranges from 0-50 mm (0-1.969 in) (with an accuracy of 0.25 mm (0.0098 in)using a rack and pinion mechanism.
- The milling depth (removable allowance thickness) is adjusted by moving only the tool post.
- The maximum distance between the lower end of the tool chuck and the worktable surface
is 78 mm (3.071 in). When the table is in its lowest position and the tool post in its highest position).
- Milling area: 21 x 15 mm (0.827 x 0.591 in)
- Work table, adjustable in two mutually perpendicular directions by 21 mm (0.827 in) and 11.5 mm (0.453in) using rack and pinion mechanisms. The table can rotate 360 degrees at a height of 14 mm (0.551in).
III. REQUIREMENTS FOR THE MILLING OPERATORS QUALIFICATION.
To achieve the required quality and accuracy of machining, a milling machine operator must have a good understanding of:
- how to select the correct milling cutter;
- how to set optimal milling conditions, including cutter speed and workpiece feed rate, depending on the strength and viscosity of the workpiece material;
- the purpose of each operating handle, clamp, and clamp on the machine;
Failure to understand all of the above will inevitably lead to machine failure or an accident!
