Haas VMC CNC Selection
When selecting your Haas VMC, youll want to take into consideration both your current and future needs for size, speed, versatility, power, and precision. Machines will vary by size taper, the number of axis (which determines part complexity), the spindle rpm (revolutions per minute) and tool capacity, among other things. You can speed up your selection process by learning more about the various series of milling machines that Haas offers.
Haas Milling Machines & CNC Machining Centers
Milling is a machining process of using rotary cutters to remove material from a workpiece to create a part. Vertical milling machines and mini-mills make smaller parts and the super-size parts are usually made on a horizontal machining center. Because of the ever-increasing complexity and features being added to both kinds of machines, both kinds may be referred to as machining centers. Most CNC milling machines have the ability to move the spindle along the Z-axis which allows for freedom to engrave and make much more complex parts. When a fifth axis is added, making the machine a 5-Axis machine, the B axis controls the tilt of the tool to make extremely complicated geometries. Most selections for CNC milling machines begin with the size parts you plan to machine.
VF Series Haas Vertical Milling Machines
The V in the VF series refers to vertical, and the F1 was unofficially called the Very First One. It was first sold in 1988. They caused quite a stir in the industry because no American manufacturer had ever offered machining centers for under $50,000. In our used Haas machines listing you will find that the VF1 has evolved over the years. The earlier models had considerably lower horsepower, coming it as low as 7.5, as compared to the 2018 version which is 30 hp. The progressing speed has been amped up from only 20 blocks per second to 2000 bocks per second on newer models.
Of course, computer communication has changed, and Haas has kept up. When selecting your next vertical milling machine, youll want to consider the communication method, originally it was an RS232 but now ethernet and USB are standard, and some machines are equipped with WiFi. The program memory in 1988 was just 128k, but the 2018 version now allows for 1 GB standard with options up to 64GB.
Ramping up Speed on Vertical Milling Machines
In 2002 the Super-Speed, called SS in the product line, was first introduced. If youre looking for speed, the super-speed VF-2SS is a CNC vertical mill that goes 12,000 rpm instead of 8,100 rpm like the standard series VF. All things being equal, parts made on the SS often can be made with a 20% reduction in cycle time. These fast machines were the first in the VMC series, and they are built for speed and precision.
Haas VR Series Vertical Machining Centers
Though production for the VR Series ended in 2013, you can still find them used. The VR Series of machines for Haas is a five-axis contouring machining center designed for large 5-axis machining operations. Travels range from 64 x 40 x 30 for the VR-8 to 120 x 40 x 30 for the VR-11. These machines can make large complicated parts using a dual-axis spindle with a fully enclosed gimbal design to protect gears from chips and coolant. The VR series comes standard with a 32-pocket automatic tool changer that swings out for unobstructed machining and a 30 hp, high-torque spindle. Some options to look for including the rpm of the spindle which may be 15,000 rpm or 10,000 rpm, the connectivity options and various through-spindle coolant systems.
Haas UMC Series Universal Machining Centers
The UMC Haas machining centers all come in the same size, 30 x 20 x 20 but with various features. The UMC-750 is a great 40 taper, 5 axis, 40+1 tool machine with 8,100 rpm. Add the SS and the spindle speed is increased for faster cycle times. The UMC-750P is a 5-axis profiling CNC vertical mill for extra versatility.
Haas Mini Mill Series
The mini-mill series of machines have travel distances of either 16 x 12 x 10 or 20 x 16 x 14. These are compact, economical machining centers often used in schools, for start-up shops or as a first step in a CNC machining process. The mini-mills operate on single or three-phase power and hold up to 10 tools. The Super Mini Mill has a faster spindle speed and tool changer than the original Mini Mill. The least expensive version is the Mini Mill-EDU which was made as a limited edition for schools. It only has a tool capacity of one.
Haas Drill-Tap Series (DRILL/TAP/MILL SERIES)
The DT Series are compact high-speed drill and tap machines that can mill. The DT-1 series comes at 20 x 16 x 15.5 and the DT-2 series comes with 28 x 16 x 15.5 travels. They have a powerful BT30Taper inline direct-drive spindle with 12,000 rpm capability and can hold 20+1 tools.
Haas Gantry Series
The Gantry Series routers cut large sheets or machine small parts by the thousands. These router tables have travels of 145 x 85 x 11 for the GR-712 and 121 x 61 x 11 for the GR-510. They are three-axis with 10 tool capacity and 8,100 rpm.
Compact Mill Series
For a full-featured CNC for small parts, such as the watch, medical, dental or jewelry industries, the Compact mill is an excellent choice. It has 12 x 10 x 12 travels, 3 axis and a super-fast rpm at 30,000 rpm. With its 20 tool capacity, its a great choice for parts with minute features that require extreme accuracy.
Toolroom and Mold Machines Series
These CNC machines are designed especially for making tool and molds. The toolroom mill has a large travel capacity but can be customized for the number of axis, rpm and tool capacity, making it possible to have machines that are cost-effective for specific purposes. Mold machines are designed for accuracy, thermal stability and rigidity to make molds to demanding specifications. They come in 3/4/5 axis, with 12,000 to 30,000 RPM and 24 to 40 tool capacity.
