Choosing between two used CNC machining centers can feel like comparing a project car with a daily driver. On one side is a 1991 Mori Seiki MV-Junior priced at $3,500. On the other is a 2013 Haas VF-4 with a $44,500 asking price. The gap between them forces you to choose between a low-cost fixer-upper and a newer machine with more capacity.
Quick verdict
If you are comfortable replacing a Y-axis limit switch, fixing an oil leak near the lube pump, and occasionally coaxing the tool changer arm, the Mori Seiki MV-Junior is a low-cost way into CNC milling. If you need a machine that is ready to run production parts on a larger table, the 2013 Haas VF-4 is the more dependable purchase despite the higher price. In short: choose the Mori Seiki for a project you can repair; choose the Haas for a machining center you can put to work immediately.

Where each product wins
The Mori Seiki MV-Junior wins on entry price and spindle speed; the Haas VF-4 wins on work envelope and power. The comparison table above shows the split. If the purchase is about getting a capable CNC mill for the least money, the Mori Seiki is the standout. If the purchase is about the largest work area and the most horsepower, the Haas takes it.
Product notes
Mori Seiki MV-Junior
The Mori Seiki MV-Junior is a genuine CNC vertical mill for people who do not mind turning a wrench before pushing the green button. The machine has a 35 x 16 in. table, 22 x 16 x 18 in. travels, a CAT 40 taper, and a 20-tool side-mount changer with a Fanuc control. It comes with a disclosed list of work: the Y-axis limit switch needs replacement, there is an oil leak near the lube pump, and the tool changer arm can hang occasionally. Even with those repairs, the lowest price in this pairing leaves room in the budget for parts and tooling. The machine has a track record too-the previous owner used it since 2009 and made thousands of parts on it. What holds it back: it will not make chips until you address the issues, and it is a 1991 machine.
2013 Haas VF-4
The 2013 Haas VF-4 is the option to choose when the goal is output, not restoration. At the top of this price pairing, it justifies itself with a 50 x 20 x 25 in. work envelope, a 52 x 18 in. table, a 20-hp spindle, and a 7,500-rpm top end. The Haas CNC control and coolant system are already in place, and the 20-tool ATC covers most job-shop work. At 13,500 pounds, it is the heavier of the two. The catch is the upfront cost: the asking price is far higher than the Mori Seiki, so it demands a serious budget or financing. If you need a vertical machining center that can handle larger parts and has newer controls, this Haas is the stronger fit.
Final choice by use case
Choose the Mori Seiki MV-Junior if you want a low-cost vertical machining center and have the skills to replace a limit switch, trace an oil leak, and work through a sticky tool changer. It is also a reasonable fit for low-volume prototype work or as a second machine for a shop with existing CNC support. Choose the 2013 Haas VF-4 if your priority is production capacity and your budget can reach the higher asking price. That machine is built to go into production without a project plan.
