The fading light of day plays across the machined surfaces of a Haas VF-2 column casting on the Haas assembly floor. More than 85% of all VF-2 parts are made in the Haas factory, and all major castings and critical machined parts are machined on Haas machines. These columns are machined complete in a pair of robotically loaded Haas EC-1600YZT HMCs.
Here at Haas Automation, we take full advantage of the capacities and capabilities of every machine in the shop to produce the right number of parts at the right time, in the most efficient way possible. Here, we’re utilizing the high-speed capabilities and large table of a Haas VF-3SSYT VMC to precision chamfer gears for the Haas 40-taper gearbox – 20 gears at a time, in a single setup.
It’s a high-production environment, and we put as much thought and engineering into optimizing our workholding and machining processes as we do into designing high-quality components for Haas machines.
These pinion gears for the Haas C-axis drive system are fresh off the hone and ready for final grind, before going to the assembly floor. The C axis system is included with the live tooling option on Haas turning centers to provide interpolated bidirectional motion at precise speeds and feeds for part positioning and repeatability.
The concept of a machine that can provide multiple axes of movement for cutting metal and other materials has changed very little since the dawn of the industrial revolution. These simple, basic tools, however, have benefited substantially from the application of computer technology. The modern Turning Center uses CNC (computer numerical control) to coordinate both simple and unbelievably complex movements of those axes. While electronic servomotors can provide axis movements in the tenths of a thousandth of an inch, the amazing performance of these machines is the result of high-precision positioning encoders, high-performance axis drives, and the powerful computer control that coordinates the axis movements and is able to repeat them precisely. Using a computer language called G-code, machining programs can be developed and tested offline, and then transferred to the machine and run with minimal human interaction.
These cam follower arms for the Haas side-mount tool changer are fresh off one of the many Haas EC-400PP pallet-pool HMCs in the Haas machine shop. The material for the arms is rotary surface ground, and then the blanks are loaded into an EC-400PP to cut the profiles. The profiled blanks are then loaded into another EC-400PP to machine the fronts and backs of the arms. When assembled to the tool changer cam box, the arms drive the shaft that raises and lowers the double-arm during a tool swap.

Haas inline direct-drive spindles use a Haas-designed and -built magnetic encoder assembly mounted to the motor to precisely control spindle rpm, and provide closed-loop feedback for accurate rigid tapping.
This heavy-duty, chain-drive system on the Haas Automatic Pallet Changer (APC) swaps pallets quickly to keep non-cutting time to a minimum. Available on Haas VF-3 and VF-4 VMCs, the APC boosts productivity by allowing non-machining tasks, such as part changeovers and fixture setups, to be performed on one pallet while parts are being machined on the other.
Haas machine tools feature a minimal lubrication system that optimizes the amount of lubricant supplied to the machine components. The system supplies lubrication only when needed – based on distance traveled or number of spindle revolutions. This reduces the amount of lube required, and eliminates excess lube that could contaminate the coolant.
These liner guide adapters for Haas turning centers are machined from 6061 T6 aluminum in two turning operations on a Haas ST-30Y, and one milling operation on a Haas VF-4 in the Haas machine shop. Next, they will be sent for black anodizing, before being packaged in the appropriate liner kit for the new Haas Bar Feeder. The yellow plastic mesh protects the threads on the adapters during transportation.
The liner guide adapters are manufactured in various sizes to match the spindle bore of each model of Haas turning center. They allow the turning center to use Haas Automation’s patented extruded spindle liners for bar feeding or bar pulling operations. The spindle liners ensure the bar feeds smoothly and accurately into the machine’s chuck or collet, and provide support for the bar as it turns.
These gears are destined for the gearbox of a Haas 50-Taper VMC. With the exception of heat-treating, Haas makes these gears entirely in-house. The gear blanks are machined in one operation on a Haas SL-25APL two-spindle CNC turning center with automatic parts loader and live tooling before going to the gear hobber. After hobbing and heat-treating, they are precision-ground for parallelism and perpendicularity before heading to assembly. Strict Quality Control procedures are observed at every step of production to ensure the high quality and dependability expected from Haas.

Completed side-mount tool changers on the assembly line at Haas Automation.
Side-mount tool changers are one of the most popular options for Haas small- and medium-frame VMCs, and they come standard on Haas large VMCs and HMCs. Not only do they hold more tools than a carousel-style tool changer, but they also provide faster tool changes, and store tools out of the work envelope for unobstructed machining.
The concept of a machine that can provide three axes of movement for cutting metal and other materials has changed very little since the dawn of the industrial revolution. These simple, basic tools, however, have benefited substantially from the application of computer technology. The modern HMC uses CNC (computer numerical control) to coordinate both simple and unbelievably complex movements of those three axes. While electronic servomotors can provide axis movements in the tenths of a thousandth of an inch, the amazing performance of these machines is the result of high-precision positioning encoders, high-performance axis drives, and the powerful computer control that coordinates the axis movements and is able to repeat them precisely. Using a computer language called G-code, machining programs can be developed and tested offline, and then transferred to the machine and run with minimal human interaction.
Dry machining 1018 steel on a Haas VM-3 using the Haas Minimum Quantity Lubrication (MQL) and Auto Air Gun options. The MQL system works through the Auto Air Gun to deliver a steady flow of compressed air and a small quantity of cutting oil directly to the cutting tool, which reduces heat, removes chips, and provides lubrication.
These blanks for Haas transmission gears are queued-up for hobbing on a Koepfer gear hobber in the Haas machine shop. The blanks are gravity fed to a robotic arm, which loads them into the machine for hobbing, and then automatically stages the completed gears for the next operation. Before hobbing, the gear blanks are turned, drilled, and tapped on a Haas SL-20APL with automatic parts loader and live tooling.
These 50-taper drawbars are fresh off a Haas ST-20 in the Haas Automation machine shop. The shafts start as bar stock that has been centerless ground to size, and then cut to length. The shafts then go into the ST-20 for OD and ID threads and finish turning, before moving to a Haas VMC for a set of milled flats. The shafts are then gundrilled for the TSC through-hole.
