Comparison between Manual Milling Machines and CNC Machines


The Bridgeport-style knee mill is still in use, and despite the development of CNC machine tools, a manual milling machine can be found on almost every shop floor.

A power supply, digital readout, collet rack, and vise affixed to the work bench are all possible features. The manual knee mill is still used for minor operations that require a rapid setup and only a few perforations in the workpiece.

In addition, so because head tilts, the ram travels, and the turret rotates, the manual milling machine is ideal for activities that demand a quick turnaround or don’t lend themselves to CNC programming.

Worker controls the CNC machine

Conventional Milling Machines Offer Benefits That CNC Milling Machines Do Not.

Although both CNC and manual milling are effective of vertical milling, one of the key distinctions between the two is the number of people required. CNC milling needs little interaction, and a skilled CNC machinist may handle many machines at once, whereas manual milling often requires just one worker. CNC milling’s most obvious advantage is lower labor costs.

Find A Milling Machine That Incorporates The Greatest Aspects of Both Manual and CNC Milling.

The Supra vertical milling machine may run for hours without the need for an operator present or for component changes only on shorter runs, depending on the sort of job you’re performing. Micro-stepper motors power the X-axis, Y-axis, and feather Z-axis, which may all move at the same time for 3-dimensional work, while the software controls the variable speed head. Despite this, the CNC Supra may be controlled manually for those minor jobs that arise while all of the others CNC mills are busy. In machinery that use CNC Supra vertical hammer mill, the classic manual mill may have gone obsolete.

Is a CNC Milling Machine With a Lower Footprint Required?

Despite the fact that the CNC Supra Vertical Knee Mill takes up much less space than other industrial machinery, your scenario may need the use of a smaller CNC milling machine. If that’s the case, the CNC Max Tabletop Mill is the answer to your problems. The MAX has a large travel range: 21.5″ on the X-axis, 10.5″ on the Y-axis, and 4.5″ on the Z-axis quill. For precision on such manufacturing runs, all 3 components are puck driven.


Despite the fact that CNC milling has a significant advantage over conventional milling in terms of labor savings, quality and repeatability, the capacity to handle complicated three-dimensional work, and enhanced adaptability, manual milling machines still have a place and purpose in any businesses. Those just starting out in company may choose to go with a less costly manual machine, while those without computer abilities may want to skip the CNC mill for now.

And, if your company is working on a number of large projects, having a manually milling machine on hand for little crises is a good idea.
