Precision Matthews PM-727M benchtop mill

This machine falls into the mid-size benchtop mill category. Larger than the PM-25M but economically priced. It too requires NEMA 34 stepper motors on all axis. The Precision Matthews pm727m benchtop mill is your best bet for entry-level and small-scale machining. You can also transform them into CNC for improved machining using our conversion kits.

The Precision Matthews PM-727M benchtop mill is a compact machine yet capable of handling heavy workpieces. 


While other mills of this class are equipped with plastic gear, the PM-727 M’s machine head features hardened and ground steel. This allows the mill to cut through the bulkiest materials. 


Thanks to the size of the PM-727M benchtop mill, space is no longer a constraint for workshops. That’s because the dimensions of 39″ x 74″ x 30″ mean you can install this just about anywhere. 


Coming to machining, the mill is simple to operate even during such operations that call for high tolerances. Its .001″ table graduation on X and Y axis and inch pitch lead screw ensures you don’t face any difficulty while making cuts or drills.


Also, you can follow the manufacturer-provided user guide to complete the machine setup and start operations. 


An intelligent design attaching a column to the base and a wide mounting area makes the Precision Matthews PM-727M mill way more rigid than similar mills of its class. 


The mill needs a single-phase 120-volt circuit, which is standard for buildings across the country. So you need not install any additional circuits in your machine shop. 


The PM-727M benchtop mill is covered by a 3-year long manufacturer warranty, the longest of most mills. 


Although the PM-727M mill is a manual machine, you can get a Precision Matthews conversion kit and turn this mill into CNC in a cost-efficient way. 


Further, we can also customize these turn key machines to meet your specific requirements.
