What Is a Horizontal Milling Machine?

Horizontal milling machine is a kind of machine tool. Its main axis is parallel to the table, it is in a horizontal position, and its rotation speed is 12 steps. Plane, bevel, groove, etc. It can be divided into universal horizontal milling machine, horizontal lifting table milling machine, universal rotary head milling machine and so on.

Bed: used for fixing and supporting

Horizontal milling machines are stable in quality and can be machined if suitable milling machine accessories are used

When using an ordinary milling cutter for milling on a horizontal milling machine, the movement trajectory formed by the milling cutter edge is a cycloid curve, so the chip changes from thin to thick during the upper milling period, and the milling cutter is stressed when it is stressed, and the cutting edge is avoided Fractured by impact. During down milling, the chips change from thick to thin, the milling cutter is under heavy load and light at the end, and it is easy to produce an impact to break the blade.

When milling on a horizontal milling machine, the roughing method uses the upper milling method, and the fine milling method uses the lower milling method. When using down milling, the screw of the milling machine needs to have a clearance eliminating device, otherwise it is easy to generate vibration and cause poor cutting surface.

Advantages of horizontal milling machine

The machine tool has good rigidity and can bear heavy load cutting.

The spindle motor of the horizontal milling machine has high power, wide speed range, and gives full play to the tool's efficiency and high-speed cutting.

The wear-resistant castings are made of vanadium-titanium wear-resistant cast iron, and important parts are made of high-quality alloy steel, which is stable and durable.

The machine tool has a perfect lubrication system.

Horizontal milling machine can be equipped with digital display device according to user needs. The product is easy to operate and has reliable performance. Various plane milling cutters, disc milling cutters, angle milling cutters, forming milling cutters and end milling cutters can be used to process various planes, inclined planes, grooves, etc.

Advantages of milling method on horizontal milling machine

It can be used in old milling machines, and does not produce invalid clearance movement of the screw;

Suitable for milling the black leather surface of castings;

The teeth of the milling cutter are light and heavy, and the blade is not easy to break.

Disadvantages of milling method on horizontal milling machine

There is more friction, the blade is easy to be blunt, and the life is short;

Easy-to-vibrate cutter, rough machining surface and poor machining accuracy;

The device is not easy and is not suitable for milling thin workpieces;

consumes a lot of energy.

Advantages of the down milling method of horizontal milling machine

Less friction during processing and longer life of milling cutter;

Easy clamping, no vibration, high precision of machined surface;

Easy to prepare, suitable for long and thin workpieces.

Four feeds consume less power.

Disadvantages of the down milling method of horizontal milling machine

The screw of the milling machine needs a clearance eliminating device, otherwise it is easy to produce invalid clearance movement;

Not suitable for milling cast iron and forgings;

Mill teeth are easily broken due to impact.
