Choosing a bench metal lathe often comes down to capacity, precision features, and what you're comfortable spending. The two candidates here sit at opposite ends of that spectrum: the Precision Matthews PM-1130V is a full-featured bench-top lathe with a 2-axis DRO, while the 8.7x18 automatic-feed lathe targets lighter work and a smaller footprint.
Quick verdict
If your projects involve longer stock, precise measurements, and a machine that arrives with a digital readout installed, the Precision Matthews PM-1130V is the more capable choice. If you're turning smaller diameters and want automatic feed and electronic threading without a major outlay, the 8.7x18 bench lathe is the practical alternative.

Where the Precision Matthews PM-1130V fits
The PM-1130V is built for bench-top work that demands precision and repeatability. Its factory-installed 2-axis DRO takes the guesswork out of positioning, while the 1.5 HP AC inverter drive provides variable speeds in two ranges-low for torque, high for speed. The power cross feed works in both directions. This makes it a strong fit for a shop that regularly turns longer parts or needs to match threads on repair jobs. The top speed is lower than the smaller lathe, which is worth keeping in mind for very small-diameter finishing.
Where the 8.7x18 fits
The 8.7x18 bench lathe (model MX-S450) focuses on lighter work. The electronic threading system simplifies switching between metric and imperial units, and the fully automatic feed reduces manual effort on repetitive cuts. The cast iron and aluminum alloy construction handles soft metals, acrylics, and plastics well. This machine suits small shafts, bushings, and repair work.
Product notes
Precision Matthews PM-1130V Bench Top Metal Lathe
The PM-1130V comes with a 6-inch chuck and a 30-inch distance between centers, which puts it in a different class from the 8.7x18 for longer workpieces. The 2-axis DRO is a standout addition, giving you a built-in readout without the need to install one after purchase. The 1.5 HP inverter drive offers two speed ranges, and the power cross feed cuts in both directions. Threading includes inch, metric, right-hand, and left-hand forms, so you can handle a wider variety of jobs. If you want a bench lathe that is ready for precise, repeatable work, this is the more complete package. The lower top speed of 2000 rpm may limit very fine work on tiny diameters.
Metal Lathe Machine 8.7 x 18 in Precision Bench Power Metal Lathe Automatic Feed
The MX-S450 takes a simpler approach with an 18-inch maximum length and 8.7-inch maximum diameter. Its 1250W brushless DC motor is quiet and requires no maintenance, and the 2500 rpm top speed gives you headroom for small-diameter finishing. Cast iron and aluminum alloy construction keeps the machine stable while cutting soft metals, acrylics, and plastics. The clear limit is the work envelope: you cannot turn stock longer than 18 inches or wider than 8.7 inches without moving up to a larger lathe.
Final choice by use case
Both lathes have their place. The PM-1130V is the machine to budget for when you need a lot of built-in precision. The 8.7x18 is the one to start with if you're working small.
