Every CNC shop eventually faces the same buying fork: do you put money into a complete machining center or into the setup tool that makes an existing machine more accurate? The choice between the 2013 Haas VF-4 Vertical Machining Center and the USA 3D Trigger Edge Finder CF-38 is not a normal head-to-head, because one is the machine and the other is the accessory. But that difference is exactly why you need to think through it before spending.
Quick verdict
Buy the Haas VF-4 if your shop needs an actual vertical machining center with a 50" x 20" x 25" envelope and a 20-tool automatic tool changer. Buy the CF-38 3D Trigger Edge Finder if you already have a CNC machine or router and your next dollar is better spent on precise, repeatable edge finding during setup.
At a glance: Haas VF-4 vs CF-38

| Listed price | USD 44,500.00 | USD 102.60 |
| Price bar | ||
| Condition | Used | New |
| What it is | Complete vertical machining center with Haas CNC control and coolant system | 3D trigger edge finder for locating edges and coordinates |
| Key specs | 50" x 20" x 25" travel, 52" x 18" table, 20 HP, 7,500 RPM, 20 ATC | Repeat positioning accuracy ≥0.005, probe directions ±X ±Y +Z, trigger life ≤3 million times |
Where each product wins
The Haas VF-4 wins when the job is producing parts. It has the travels, table space, horsepower, and tool capacity to act as the center of a shop. The 52" x 18" table and 3,500 lb table load capacity mean it can handle workpieces that a benchtop edge finder cannot even touch.
The CF-38 wins when the bottleneck is setup. Instead of bumping an edge and taking a guess, this 3D trigger edge finder locates edges in ±X, ±Y, and +Z with repeat positioning accuracy of ≥0.005, and it has a trigger life rated up to 3 million times. For a shop that already has a spindle, that kind of repeatability is worth a lot.
Product notes
2013 Haas VF-4 Vertical Machining Center 50" x 20" x 25" #8340
This is the complete machining center purchase. The VF-4 combines a 20 HP spindle running at 7,500 RPM with a 20-position automatic tool changer, so you can run longer cycles without swapping tools by hand. Its 50" x 20" x 25" travels and 52" x 18" table give you room for substantial workpieces, and the Haas CNC control plus coolant system are already part of the package. The limitations are practical: it is a used 2013 machine, and it occupies a serious footprint at 118" x 110" x 117.5" and 13,500 lbs. Make sure your floor, power, and rigging can handle it before you commit.
USA 3D Trigger Edge Finder to Find CNC Machining Center Three-Coordinate CF-38
This is the precision setup tool. The CF-38 is a new 3D trigger edge finder with a tungsten steel probe and ruby tip, and it is designed with waterproof and dustproof construction for shop-floor reliability. It finds edges in ±X, ±Y, and +Z, with repeat positioning accuracy of ≥0.005. The package includes the CF-38 probe and one tip, but not the CR1632 button cell battery, so you will need to provide that yourself. The limitation is that it is an accessory, not a machine: it cannot replace a spindle or a work envelope. It only pays off when there is a CNC machine or router already in the shop to use it on.
Final choice by use case
- Choose the 2013 Haas VF-4 if you are buying (or replacing) the actual production machine. It gives you a vertical machining center with a 50" x 20" x 25" envelope, a 20-tool ATC, and the structural capacity to handle heavy table loads.
- Choose the CF-38 3D Trigger Edge Finder if your CNC machining center or router is already running and you want faster, more repeatable edge finding during setup.
- If the budget only covers one line item, ask whether a machine already exists. No edge finder can cut a part, and no machining center is as quick to set up as a dedicated probe.
