Whether it’s laser cutting, precision sheet metal fabrication, press breakwork, manual lathe or mill, CNC milling or  CNC tunning with our GibbsCAM full 3D Cad/Cam software, MMI is ready to make it happen.

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.

That’s what Master Machining, Inc. has provided its customers for over 30 years. If you want a design, machining and fabrication partner that takes pride in every project and brings solutions to the table, then you need MMI. From prototypes to large  productions to full assemblies, MMI wants to make you look good with their end-to-end solutions. Our 16,500 square foot facility stocks 70% of common use materials, so your tight deadline is no problem for us.

※Divide by 1000 to change to m from mm. vc (m/min) : Cutting Speed Dm (mm) : Workpiece Diameter π (3.14) : Pi n (min-1) : Main Axis Spindle Speed

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

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.

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.
