Summary

This educational video explains the function and components of a milling machine, focusing on the vertical milling machine. The narrator introduces the machine's parts, such as the drive motor, machine head, spindle, and machine table, alongside auxiliary tools like the vise. Different types of milling machines (horizontal, vertical, and universal) are also discussed, highlighting key distinctions in spindle positioning. The video demonstrates how to install the milling knife and provides an overview of essential buttons, slides, and the machine's base. It aims to help viewers understand the milling process and the machine’s structure and functionality.

Takeaways

• 😀 A milling machine is a machine tool that uses a rotating cutter to cut or shape a workpiece mounted on the machine table.
• 😀 The three main types of milling machines are horizontal, vertical, and universal, each differing in the position of the machine spindle.
• 😀 The vertical milling machine has a spindle positioned perpendicular to the machine table.
• 😀 The main parts of a vertical milling machine include the drive motor, arm, machine head, machine spindle, collet, and milling knife.
• 😀 The drive motor converts electrical energy into mechanical motion to move the main spindle.
• 😀 The arm connects the machine body with the machine head and allows adjustment of the machine's angle and position.
• 😀 The machine head holds the spindle and can move up and down while adjusting the angle of the milling tool.
• 😀 The milling machine table supports auxiliary tools like the vise or dividing head and is used to hold the workpiece.
• 😀 The knee of the milling machine supports the table and helps move it longitudinally or transversely.
• 😀 The buttons on the milling machine control various functions, including the machine's spindle, lighting, cooling system, and automatic movement of the table.

Q & A

What is a milling machine?

A milling machine is a machine tool that rotates a milling cutter by a spindle at a certain speed to cut or shape the workpiece mounted on the milling machine table.

What are the main types of milling machines?

The main types of milling machines are horizontal milling machines, vertical milling machines, and universal milling machines. The primary difference lies in the orientation of the machine spindle.

What distinguishes a horizontal milling machine from a vertical milling machine?

In a horizontal milling machine, the spindle is positioned horizontally, while in a vertical milling machine, the spindle is positioned vertically or perpendicular to the machine table.

What is the purpose of a universal milling machine?

A universal milling machine combines features of both horizontal and vertical milling machines, with a spindle that can be adjusted to both horizontal and vertical positions.

What is the role of the drive motor in a vertical milling machine?

The drive motor converts electrical energy into mechanical motion, which moves the main spindle and drives the automatic movement of the machine.

What function does the arm or arm part of the milling machine serve?

The arm connects the machine body to the machine head and can be adjusted both forward and backward, as well as in terms of angle.

What is the machine head in a vertical milling machine responsible for?

The machine head holds the machine spindle and allows movement both up and down. It also adjusts the slope of the milling channel.

How is the milling cutter mounted on the machine?

The milling cutter is installed on the arbor, which is tightened by a locking bolt. A collet and milling knife are used to secure it, and it is tightened using a key.

What is the function of the milling machine table?

The milling machine table holds and supports auxiliary tools, such as a vise or dividing head, during the milling process.

What are the functions of the slides on the milling machine?

The slides on the milling machine allow for movement in three directions: the longitudinal slide (red), transverse slide (yellow), and the vertical slide (orange), which helps move the milling machine table up and down.
