Milling machines use cutting tools that are cylindrically shaped. They are capable of working on a wide range of materials, from sheet metal to wood to large blocks, in order to create products in varying shapes, sizes, and conformations as they move through the product either horizontally or vertically.

Substitute f=.008IPR, RE=.031 into the formulae. h=(.008)2÷(8×.031)×1000=.258µinch The theoretical finished surface roughness is .258µinch.

Other, more complicated machines, called Turning Centers, are capable of machining more complex parts due to their ability to move along an additional axis (y-axis) or have specific additional functionalities.

The lathe is a perfect tool to use when the operation calls for repeatable and symmetrical cylindrical parts. In a normal turning operation, the material to be cut is clamped and rotated by the main spindle. Meanwhile, the main cutting tool is attached to a cross slide, which allows the stationary cutting tool to move along different axes to facilitate the cutting of the flat material.

A milling machine is one of the most common CNC router machines you will find in any CNC workshop. In this type of machine, the cutting tool rotates rapidly and can move across different axes while the material being machined remains stationary.

Feedrate

A lathe is a type of CNC router machine wherein its main cutting tool remains stationary as the main material being machined is clamped and rapidly rotated. It is typically used in a process called turning, where the material rotates rapidly while the cutting tool slowly moves along the y-axis and removes small parts of the material to create cylindrical parts.

First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=0.2×1000=200(mm/min) Substitute the answer above into the formula. Tc=lm÷l=100÷200=0.5(min) 0.5×60=30(sec)The answer is 30 sec.

Equip your operations with top-tier CNC lathes and milling machines to give you the means to gain a competitive edge in your industry.

Typically, the cross slide allows the cutting tool to move along the x- and z-axes, enabling the cutting of the material into shapes with radial symmetry.

SFM to RPM

First, calculate the cutting length per min. from the feed and spindle speed. l=f×n=.008×1000=8IPM Substitute the answer above into the formulae. Tc=lm÷l=4÷8=0.5(min) 0.5×60=30(sec) The answer is 30 sec.

Milling machines are typically used to produce a wide variety of products, machine components and parts. This is carried out using the rapid rotating action of the cutting tool, which removes material from the workpiece gradually as it moves along the work surface.

Substitute f=0.2mm/rev, RE=0.8 into the formula. h=0.22÷(8×0.8)×1000=6.25µm The theoretical finished surface roughness is 6µm.

Lathes and milling machines fundamentally differ in how they perform and interact with production materials. In a nutshell, their difference lies in which components move while the other remains stationary during a machining operation. By understanding these differences, you can take full advantage of their capabilities and take your manufacturing operations to the next level.
