Haas CNC VF-2 Controls
The Haas control makes the VMC (Vertical Machining Center) easy to operate. Even models going to back to the year 2000 had Haas-only features like Word Processor Editing to help operators easily make changes. They carried features like one-touch, multi-function jog-handle and quick code programming even on machines made 18 years ago. They provide a robust dependable control that is integrated with the Haas CNC machine. They do not rely on third-party NC suppliers. Haas VF-2 machines have dedicated keypads with a full array of keys including a complete alphanumeric keypad with all common functions clearly labeled for operator use. Operators dont need to remember any encrypted codes. Keep in mind, if you are buying an older Haas, its very likely that the control can be updated.
The Haas CNC VF-2 controls come with one-button features to make common multi-step functions fast. For example, a tool offset can be reduced to the push of one button. Other common functions of the one-button function include setting work offsets, homing the machine and selection the next tool during setup. The jug-handle on most CNC machines is used to only move the axis around. But on the Haas VF-2, the jog-handle can be used in other modes to cursor through the program for overriding spindle speeds, faster editing, or to scan through offsets, parameters, etc. All of this is easy to see on the high-density, high-contrast LCD screen that is common to many years of VF-2 production. This 15 TFT LCD display screen will not wash out in bright light because the panel is mounted behind anti-glare tempered glass for production and easy viewing. The USB port makes it easy to use your own USB flash memory devices or external hard drives if you are not connecting via ethernet or Wi-Fi.
DWO/TCP on VF 2 Haas CNC
When looking for a used Haas VF-2, consider asking about the DWO/TCP option. This stands for Dynamic Work Offsets and Tool Center Point Control. Its a software feature designed by Haas to increase productivity and reduce setup times. It makes setting up easy by allowing an operator to place the part and fixture anywhere on the machines table or platter. The machine will find it no matter the location that was programmed by the CAM system. DWO and TCPC determine the difference between the centers of rotation which are programmed in the CAM system and the centers of rotation inside the machine and applies the appropriate offsets. This saves money by eliminating costly work holding, like self-centering fixtures and the regeneration of programs by CAM systems.
Haas Rotary Table & Fixturing Accessories for Haas VF2
Haas offers rotary tables that may be sold along with a used VF2. Youll see these listed along with the VF2 with model numbers like HRT160, HRT160SS, HRT210, HRC210, HRT210-2, etc. These add 4th axis capability for round parts to odd-shaped castings. They are T-Slotted rotary table that allows for very flexible fixturing. All Haas mills can have this added to the Haas control in the field to gain multi-axis capability. Haas also has a wide range of workholding solutions from tailstocks to quick-change fixture plates to manual scroll chucks. You will want to inquire about any additional fixturing tooling that may be included with your used VF-2 Haas CNC. New, the small rotary tables cost between $9,000 and $10,500 and medium tables (the HRT210 and HRT310 series) run between $10,500 to $16,000. Since you can boost your production with high-precision rotary products, they are well worth the extra expense.
Buying A Haas VF2 CNC
Buying a used CNC vertical machining center like the VF-2 is similar to buying a used car. Like the new car that loses the greatest percent of the value the day you pull it off the lot, its when a brand-new machine leaves the manufacturer that it loses most of its value. The good news is that after the initial depreciation, Haas used CNC machines hold their value MUCH better than cars.
The base model new VF-2 machines from Haas have consistently sold for between $49,000 and $52,000 for the last 10 years. When prices are above this in the used Haas CNC market, youre likely to find extras like through spindle coolants, chip augers, programmable coolant, spare M codes, coolant filters, 4th axis drive, 4th axis rotary tables, side ATC and more. Youll also find pricing varies depending on the condition, the number of spindle hours and age of the VF-2 CNC.
And like a car, new CNC machines every year come out with bells and whistles that incrementally improve production capability and accessories to improve performance.
The VF-2 configurations have changed relatively little making it a great option to buy used. Because of its popularity, finding machinists for the VF-2 is easier than for other CNCs. When you are looking at a used VF-2 Haas machine for sale, youll want to get photos and carefully inspect for signs of wear and tear, get the maintenance records as well as the hours of operation.
