About Haas Automation

Haas Automation was founded in 1983 by Gene Haas and quickly became one of the most recognizable names in CNC machining. The company’s first major breakthrough came in 1988 with the introduction of the Haas VF-1 vertical machining center, which was designed to provide machine shops with a reliable and affordable CNC milling platform.

Since then, Haas has grown into one of the largest CNC machine tool manufacturers in North America. Thousands of Haas machines are installed in machine shops across the United States and around the world.

One reason Haas remains popular in the used machinery market is the company’s focus on simple machine design, standardized controls, and strong service support through Haas Factory Outlets.

Another reason is Haas’s clear machine naming structure. Once you understand how Haas organizes its machine families, it becomes easier to identify exactly what type of machine you are looking at and how it fits into a machining operation.

Haas Vertical Machining Centers

Haas is best known for its vertical machining centers, particularly machines in the VF Series.

The VF Series is one of the most widely used CNC mill platforms in the industry. Machines such as:

• Haas VF-1
• Haas VF-2
• Haas VF-3
• Haas VF-4
   

In Haas naming conventions, VF stands for Vertical Factory, while the number typically identifies the machine size and travel capacity. For example, the VF-2 is one of the most widely searched Haas models and is often considered a standard job shop CNC mill.

Other vertical machining platforms include:

• Haas Mini Mill
• Haas Super Mini Mill
• Haas VM Series mold machines
   

Because of their reliability and simplicity, Haas vertical machining centers are often one of the most searched CNC machines in the used equipment market.

Haas Horizontal Machining Centers

Haas also produces horizontal machining centers designed for higher production machining environments.

These machines are commonly found in the EC Series, including models such as:

• Haas EC-400
• Haas EC-500
• Haas EC-1600
   

Horizontal machining centers allow shops to machine multiple sides of a part in a single setup, improving efficiency and reducing cycle time.

Buyers searching for a used Haas horizontal machine often look for EC-series models because of their ability to handle larger parts and automated pallet systems.

Haas 5 Axis Machining Centers

Haas also manufactures several multi-axis machining platforms designed for complex part production.

One of the most recognized families is the UMC Series, which includes machines such as:

• Haas UMC-500
• Haas UMC-750
• Haas UMC-1000
   

The UMC designation stands for Universal Machining Center, referring to the machine’s ability to perform full 5-axis machining.

These machines are widely used in aerospace, medical, and complex component machining environments where multiple part orientations are required.

Haas CNC Lathes

In addition to machining centers, Haas manufactures a full range of CNC turning centers.

Haas lathes are typically found in two major families:

SL Series

Older Haas lathes such as the SL-20, SL-30, and SL-40 remain common in the used market.

ST Series
Newer Haas turning centers are part of the ST Series, including machines such as:

• Haas ST-10
• Haas ST-20
• Haas ST-30
• Haas ST-40
   

In Haas naming conventions, ST refers to “Series Turning”, while the number generally indicates machine size and capacity.

These machines are widely used for producing shafts, fittings, bushings, and other turned components.

Haas Drill & Tap Machines

Haas also produces high-speed machining platforms known as Drill & Tap machines, often used for smaller precision parts.

These machines are commonly found in the DT and DM Series, including:

• Haas DT-1
• Haas DT-2
• Haas DM-1
   

Drill & tap machines are designed for high-speed production of smaller components, particularly in industries such as electronics, medical devices, and small precision machining.

Haas Gantry Machines and CNC Routers

For larger machining applications, Haas produces gantry-style machines and routers designed for cutting large parts and plates.

These machines are commonly found in the GR Series, including:

• Haas GR-510
• Haas GR-712
   

Gantry machines are often used for machining large aluminum plates, molds, and fabricated components.

Why Buyers Look for Used Haas Machines

Buyers searching for used Haas equipment are often looking for a combination of:

• reliable CNC platforms
• easy-to-learn control systems
• strong parts and service availability
• widely recognized machine families
• machines that are common in U.S. job shops
   

Because many buyers search for machines by exact model numbers, terms like Haas VF-2, Haas VF-4, Haas ST-20, and Haas UMC-750 often carry strong search intent in the used machinery market.

That is why strong Haas brand pages include both machine type keywords and model family names.
