What is machining?

Machining is the removal of material in the form of chips. You size a workpiece by turning, milling, drilling, or grinding. You determine accuracy, shape, and roughness. The result: fits are correct, tolerances are met, and parts perform stably.

Why machining matters for your production

Your production relies on dimensional accuracy, repeatability, and lead time. Machining delivers tight tolerances and perfect surfaces. You minimize failure costs. You increase output. With the right machine, you choose quality without detours.

How does machining work in practice?

A cutting tool removes material with cutting speed, feed, and depth. Coolant removes heat and chips. You select the cutting insert or milling geometry based on material: steel, stainless steel, aluminum, or cast iron. This way, you keep tool life high and surface roughness low.

Main machining processes

• Turning: round parts, shafts, fits, and thread forms.

• Milling: planes, slots, profiles, and 3D contours.

• Drilling/reaming: precise holes with tight tolerances.

• Boring: large, precise bores in heavy components.

• Grinding: ultra-fine roughness and excellent dimensional accuracy.

What machines are there for machining?

For used machines, consider reach, power, spindle speed, table load, and control. Typical choices:

• CNC lathes: Series and precise turning. Ideal for shafts and flanges.

• CNC machining centers (3–5-axis): complex milling parts in one setup.

• Bed milling machines: long workpieces, heavy machining, easy accessibility.

• Drilling/boring machines: large housings, motor housings, and plates.

• Surface grinders: mirror-smooth surfaces and tight tolerances.

• Column drilling machines: fast and robust for hole patterns and secondary operations.

Why used machining machines are better

Used top brands offer performance for less investment. You can start faster with less risk. A reliable machine dealer offers demonstrations, quick delivery, and proven service. This way, you can scale up production powerfully. Additionally, you care better for the world and your business as a result. By buying a second-hand machining machine, you save CO2 emissions and spend less money. The money you save can be reinvested into the business.
