USED HAAS UMC750SS – 2018
The 2018 HAAS UMC750SS is a 5-axis CNC universal machining center designed for manufacturers that need high-speed machining, multi-sided access, and reduced setup requirements. The UMC750SS combines a vertical machining center platform with an integrated dual-axis trunnion table, allowing manufacturers to perform 3+2 machining as well as simultaneous 5-axis machining. The documented 2018 configuration provides 30 inches of X-axis travel, 20 inches of Y-axis travel, and 20 inches of Z-axis travel, giving the machine a substantial working envelope for medium-sized components.
The “SS” designation identifies the Super Speed version of the UMC750. Compared with the standard UMC750, the UMC750SS is equipped with a higher-speed spindle and is designed to provide faster machining cycles. Documented 2018 machines are equipped with a 15,000 RPM inline direct-drive spindle rated at 30 HP, providing the spindle speed required for aluminum, stainless steel, plastics, brass, and many other materials.
The integrated trunnion is one of the most important features of the UMC750SS. Its B axis tilts from approximately +120 degrees to -35 degrees, while the C axis provides 360 degrees of rotation. This allows the cutting tool to approach multiple faces and complex surfaces from different orientations without repeatedly removing and repositioning the workpiece.
The UMC750SS uses a 19.7-inch diameter platter with a documented maximum workpiece load of approximately 660 pounds. The platter incorporates T-slots and a precision pilot bore for flexible workholding and fixture positioning. This makes the machine suitable for vises, custom fixtures, tombstone-style workholding arrangements, and other 5-axis production setups.
Tool management is handled by a side-mount automatic tool changer. The documented 2018 machine has a 40-position tool changer, while Haas specifications for the UMC750SS family also identify 30+1 and 40+1 configurations depending on production version and equipment. The 2018 used-machine examples specifically show a 40-position ATC.
The UMC750SS also benefits from Haas’ Next Generation CNC control environment. Documented 2018 machines include features such as Dynamic Work Offsets, Tool Center Point Control, rigid tapping, high-speed machining, macros, Ethernet, USB, wireless networking, and Renishaw Wireless Intuitive Probing System. These functions are particularly valuable when the machine is used for complex multi-axis components.
Another important production feature is through-spindle coolant. A documented 2018 UMC750SS includes through-spindle coolant, programmable coolant, a chip conveyor, and an auxiliary coolant filter. These systems can improve tool life, chip evacuation, and cutting performance during deep-hole drilling, pocketing, and high-material-removal applications.
The UMC750SS is particularly well suited to aerospace, defense, medical, automotive, energy, mold and die, precision engineering, and general contract manufacturing. Its ability to machine multiple faces in one setup can reduce fixture changes, improve positional accuracy between features, and shorten overall production time.
For manufacturers purchasing a used 5-axis machining center, the 2018 HAAS UMC750SS provides an attractive combination of high spindle speed, 5-axis capability, 30 × 20 × 20 inch travels, 40-tool capacity, probing, through-spindle coolant, and Haas CNC control.

WHY CHOOSE HAAS UMC750SS
The biggest advantage of the UMC750SS is its integrated 5-axis capability. Instead of removing and repositioning a component for every face, the machine can rotate and tilt the workpiece to access multiple surfaces.
The 30 × 20 × 20 inch travels provide a substantial working envelope for medium-sized components. This makes the UMC750SS suitable for significantly more than small 5-axis prototype work.
The 15,000 RPM spindle is another major advantage over the standard UMC750. The higher speed is useful for small cutters, high-speed finishing, aluminum, plastics, brass, and other applications where elevated spindle speed can improve productivity.
The 30 HP spindle motor also provides sufficient power for substantial material removal. This gives the machine a useful combination of high-speed machining capability and general-purpose cutting performance.
The integrated B/C trunnion provides +120 to -35 degrees of tilt and 360 degrees of rotation. This gives manufacturers substantial flexibility when machining angled surfaces, compound features, holes, pockets, and complex contours.
The 40-position tool changer allows complex programs to run with a broad selection of cutters already loaded. This can be especially valuable when machining components requiring roughing, semi-finishing, finishing, drilling, tapping, chamfering, and specialty tools.
The Renishaw wireless probing system can significantly improve setup efficiency. Automated probing can establish workpiece locations, verify dimensions, and help reduce manual setup operations.
The combination of DWO and TCPC is another major reason to choose the UMC750SS. These functions are designed to simplify and improve multi-axis machining by allowing the control to account for changes in workpiece orientation.
Finally, the UMC750SS provides a strong balance between capability and machine complexity. A manufacturer can gain true 5-axis machining, high-speed spindle performance, automatic tool changing, probing, and through-spindle coolant without moving into the much larger footprint and investment associated with some high-end aerospace machining centers.
WHY BUY USED HAAS UMC750SS
A used 2018 HAAS UMC750SS can provide access to modern 5-axis machining capability at a significantly lower acquisition cost than purchasing a comparable new machine.
The machine’s 15,000 RPM spindle and 30 HP motor make it suitable for both high-speed finishing and demanding production work. The 40-tool ATC further expands the types of jobs that can be completed without manual tool changes.
The integrated trunnion is particularly valuable for shops transitioning from 3-axis machining to 5-axis production. Instead of purchasing several specialized fixtures, the machine can use B and C axis positioning to access multiple faces of a component.
A used UMC750SS can also provide substantial savings when it already includes expensive accessories. Documented 2018 machines have been equipped with through-spindle coolant, Renishaw probing, programmable coolant, chip conveyors, auxiliary coolant filtration, and other production features.
The Haas Next Generation control is another advantage for shops already operating Haas equipment. Familiar programming, controls, tooling, and service procedures can reduce the learning curve when adding another machine.
The relatively recent 2018 model year also makes these machines attractive compared with significantly older 5-axis equipment. However, age alone should not determine value. Actual spindle hours, feed hours, power-on hours, maintenance history, crash history, and axis accuracy should all be reviewed.
One documented 2018 UMC750SS shows more than 24,000 power-on hours but substantially fewer feed and spindle hours, demonstrating why buyers should examine the complete machine-hour history rather than relying only on the year.
The trunnion should receive particular attention during inspection. Buyers should verify B- and C-axis positioning, backlash, brake operation, rotary accuracy, encoder performance, and signs of crash damage.
The spindle should also be checked at multiple speeds and under cutting load. Bearing noise, temperature, vibration, taper condition, drawbar performance, and spindle orientation should all be evaluated before purchase.
HOW MUCH DOES A USED HAAS UMC750SS COST?
The asking price of a used 2018 HAAS UMC750SS depends heavily on machine hours, spindle condition, trunnion condition, CNC options, probing, coolant equipment, tool changer, chip conveyor, tooling, and overall maintenance history.
A current used-market listing for a 2018 HAAS UMC750SS identifies the machine as being in excellent condition and equipped with a 15,000 RPM spindle, 40-position ATC, Renishaw wireless probing, through-spindle coolant, programmable coolant, chip conveyor, Next Generation Haas control, DWO, TCPC, rigid tapping, Ethernet, USB, wireless networking, and other options.
Another documented 2018 UMC750SS manufactured in November 2018 has approximately 4,927 feed-cutting hours as of June 2023 and was used primarily for plastic, stainless steel, and brass machining.
The Used CNC Exchange listing for this specific model/year currently describes an indicative used-market range of approximately $95,000 to $185,000, depending on spindle hours, condition, installed options, tooling, automation, and overall configuration. This should be treated as a market estimate rather than a guaranteed sale price or appraisal.

A machine toward the lower end of the used-market range may have higher hours, fewer options, worn tooling, or require refurbishment. A premium example with low cutting hours, a healthy spindle, accurate trunnion, probing, through-spindle coolant, chip conveyor, extensive tooling, and documented maintenance can command substantially more.
The most important consideration when purchasing a used UMC750SS is therefore not simply the 2018 model year, but the condition and configuration of the individual machine.
A properly maintained 2018 HAAS UMC750SS remains a highly capable Universal Machining Center for manufacturers requiring 5-axis machining, high-speed cutting, multi-sided access, automatic tool changing, probing, and production-oriented coolant and chip management. Its combination of 30 × 20 × 20 inch travels, 15,000 RPM spindle, 30 HP motor, 40-tool ATC, 500 mm trunnion platter, and B/C-axis capability makes it particularly valuable for aerospace, defense, medical, automotive, mold, energy, and precision manufacturing applications.
