QR Code Link to This Post
Model: OB4067. It is the smallest professional, fully working vertical-milling desktop machine in the world, with only one copy, and is also an extremely rare collector's item. It is designed for light milling of the surfaces of flat, complex-shaped parts that cannot be clamped in a vice, as well as the surfaces of round cylindrical parts. It is also for conventional and coordinate drilling. It will complement and decorate any collection of rare and unique tools and instruments.
I. MAIN COMPONENTS
- Machine bed.
- Console pillar
- Work table bracket.
- Work table.
- Work table support.
- Round table.
- Electric motor drive, 26.5V, 1A, 7000 rpm
- AC Power adapter.
-Tool chuck, 1-6 mm (0.039-0.236 in).
- Flat rubber damper in case.
- Instrument box with the set of tools.
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: 330 mm (13 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 (0.453 in) using rack and pinion mechanisms. The table can rotate 360 degrees
at a height of 14 mm (0.551 in).
- Accuracy of the work table angle of rotation: 0.75° (0°45').
III. REQUIREMENTS FOR THE MILLING OPERATOR'S 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.
