What’s the Difference Milling Machine and Grinding Machine?

What’s Milling Machine

Milling machine mainly refers to the machine tool that processes various surfaces of workpiece with milling cutter. Generally, the main movement of milling cutter is rotation, and the movement of workpiece and milling cutter is feed motion. It can process plane, groove, various curved surface, gear, etc.

Milling machine is a kind of machine tool that uses milling cutter to milling workpiece. In addition to milling plane, groove, tooth, thread and spline shaft, milling machine can also process more complex profile, with higher efficiency than planer, which is widely used in mechanical manufacturing and repair departments.

What's the Difference Milling Machine and Grinding Machine?

Milling machine is a kind of widely used machine tool. It can process plane (horizontal plane, vertical plane), groove (keyway, T-shaped groove, dovetail groove, etc.), gear dividing parts (gear, spline shaft, sprocket), spiral surface (thread, spiral groove) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the rotary body and cut off the work. When the milling machine is working, the workpiece is installed on the worktable or indexing head and other accessories. The milling cutter rotates mainly, supplemented by the feeding motion of the worktable or milling head, and the workpiece can obtain the required machining surface. The productivity of the milling machine is higher because of the intermittent cutting with multiple cutting edges. In short, milling machine can be used for milling, drilling and boring of workpieces.

What’s Grinding Machine

Grinder (grinding machine) is a kind of machine tool which uses grinding tools to grind the workpiece surface. Most grinding machines use high-speed rotating grinding wheel for grinding, and a few use other grinding tools such as oilstone, abrasive belt and free abrasive for processing, such as honing machine, ultra precision machining machine, abrasive belt grinder, grinder and polishing machine.

What is the difference between lathe and milling machine?

Lathes and milling machines are used to cut raw materials, but their cutting methods are very different. The lathe rotates the material, while the milling machine uses a rotary tool for various cutting operations. To take advantage of both, you must understand the differences between them and their respective functions.


If you need to cut material that is cylindrical, you might choose a lathe. It is better at holding work, and cutting the material will be much easier because of the nature of the machine . You can drill only on center with a lathe, so if you need an off-center hole or to make straight cuts in metal, you will be better off putting that material in a vise or fixture and cutting it using a milling machine. Angled cuts, and anything that needs to remain non-cylindrical, will be better cut in a milling machine.
