Specification

  Machine functions:

1.                  The working principle of bench type milling machine is similar to the one of the typical commercial milling machine.

2.                  It can perform milling, precision drilling and boring.

3.                  It should be accurate, safe and user-friendly.

4.                  Consists of five main parts:

• Headstock
• Column
• Machine table
• Knee
• Holding vice.

5.                  All the axes are movable with the help of hand wheel.

6.                  Simplify the structure of the machine and the number of components

7.                  Easy to assembly

8.                  Nice appearance

  Machines dimension:

1.                  Overall dimension of the milling machine:

• Height = 550mm
• Width = 400mm
• Depth = 400mm

2.                  Dimension of the machine table:

·        Length = 500mm

·        Width = 125mm

·        Height = 40mm

3.                  Dimension of the base:

·    Length = 300mm

·    Width = 160mm

·    Height = 60mm

4.                  Dimension of the column:

·    Length = 360mm

·    Width = 125mm

·    Height = 50mm

  Travelling dimension:

1.            X = 350mm

2.            Y = 150mm

3.            Z = 200mm

4.            Spindle from the column = 120 mm

  Safety:

1.                  Safety guards

·        Installed at all the moving parts of the machine where users can touch.

·        To protect users from getting hurt.

2.                  Emergency stop

·        To stop the machine immediately.

3.            All the sharp edges should be filed off.

  Quality Planning:

1.                  The acceptance criteria of the angles between each axis should be

2.                  The acceptance criteria of the angle between the table and a reference table should be

  Motor:

1.                  The size of the motor should not be too large.

2.                  It should be installed at the left hand side of the headstock

• Most of the users use right hand to adjust the height of the Z-axis
• The height of the motor may obstruct the users.

3.                  Angular speed is about 1500rpm
