The Haas VC-400 and Pallet Pool

The VC-400 combines the versatility of our small VF Series vertical machining centers with the pallet-changing ability of our EC-400 HMC. The fully integrated pallet changer allows you to set up jobs on one pallet, while you’re running parts on another pallet. In this video, we show our 6-Station Pallet Pool coupled to the VC-400 for true “lights out” capability.

VC-400 Cutting Demo

Check out this cutting demo showing the power and versatility of the VC-400. The fully-integrated pallet changer allows you to set up jobs on one pallet, while running parts on the other pallet so your spindle never stops turning.

VC-400 Spotlight

In this video, Milton and Andrew are looking at the new VC-400 pallet changing VMC. If you're interested in a productive way to keep the spindle turning more of the time on your vertically oriented parts, then stick around.

*Haas machines are designed to operate on 220 VAC (200-240 VAC) power. An optional internal high-voltage transformer (380 - 480 VAC) is available for all models, except the Desktop Machines, CL-1, CM-1, and SR Series routers. This optional high-voltage internal transformer is not field installable; it must be ordered with the machine.

Haas machines destined for Europe and the UK are configured with an internal high-voltage non-isolated transformer to operate on 400 VAC, except the Desktop Machines, CL-1, CM-1, and SR Series routers.

ATTENTION! Optional high-performance spindles may have a higher power requirement than the standard spindle. However, if the spindle horsepower (kW) does not change, the power requirement remains the same. Verify the power requirement before running power for your machine.

† Air consumption on 40-taper DC Series machines may be higher, when Through-Tool Air Blast (TAB) is activated.

Available 6-Station Pallet Pool

Whether you’re doing high-volume production runs, high-mix/low volume machining, or just want to run lights-out, you can boost the productivity of your VC-400/SS with our fully integrated 6-station pallet pool. NOTE: The Pallet Pool requires the optional 50+1 side-mount tool changer. Not field installable. Must be ordered with a new VC-400/SS.

Overview

The VC-400 and VC-400SS vertical machining centers combine the machining capabilities of a VF-1 with an HMC-style pallet changer to provide nearly continuous machining, with virtually no downtime. Load and unload parts on the pallet waiting at the load station, while the spindle is making chips in the work envelope to keep the machine producing parts. You can even set up a new job on one pallet, while your machine is making parts on the other. A dedicated pallet-scheduling table in the Haas control lets you check the status of each pallet.

Spindle

The VC Series machines feature the same powerful, shop-proven, Haas-built spindle that comes standard on most Haas vertical machining centers .

It is a 40-taper, inline direct-drive spindle, coupled directly to the motor to provide excellent surface finishes and greater thermal stability. The inline spindle is available in speeds up to 15,000-rpm, as well as HSK-A63 taper.

Liquid-cooled for long hours of reliable operation
17.125" (435 mm) wide-stance Z-axis linear guide separation for solid stability
Robust 40 mm Z-axis ballscrew and 35 mm linear guide construction
Includes multi-nozzle coolant ring for added coolant delivery coverage
Optional Programmable Coolant Nozzle with 34-positions for precise coolant delivery to multiple length cutting tools (shown in image)
Optional Through-Spindle Coolant (300 or 1000 psi)
Optional Through-Tool Air Blast
Optional Pulse-Jet System for tapping and drilling with oil

Pallet Changer

The VC-400 and VC-400SS come standard with a dual-pallet changing system for uninterrupted production. With the mill-style table, you can have two vises side by side on each pallet to run small batch parts, or you can run large parts by setting up one operation on each pallet with multiple vises.

The table features three standard 5/8" (16 mm) T-slots that accept nearly any type of workholding, for fast, easy setups.

Table dimensions: 22" x 14.5" (559 x 368 mm)
Standard 5/8" (16 mm) T-slots
Hydraulic clamping for rigid machining
Pallet maximum weight capacity is 880 lb (399 kg) each
Pallet Pool maximum weight capacity is 500 lb (227 kg) each

Hydraulic Pallet Clamping

The hydraulic power unit provides power to clamp the pallets to the pallet receiver, as well as raise and lower the pallet-changer mechanism.

Hydraulic clamping ensures repeatable accuracy for every pallet change, and provides high rigidity for heavy machining.

Pallet Pool (Optional)

Whether you’re doing high-volume production runs, high-mix/low-volume machining, or just want to run lights-out, our fully integrated pallet pool systems can boost your productivity. The VC Seriec Pallet Pool integrates seamlessly with the Haas control, which includes a simplified Pallet Scheduling Table that allows job scheduling functions from a single dedicated page. You can assign programs to each pallet, and re-start a job in the middle of the process.

6 storage locations + 1 machining station
Total of 7 functioning pallets included
22" x 14.5" (559 x 368 mm) pallets

Maximum weight per pallet ,including workholding: 500 lb (227 kg)
Not available for field installation

Side-Mount Tool Changer

The VC-400 and VC-400SS come standard with a 30+1 toolside-mount tool changer.

We’ve produced our own tool changers since 1988, with complete integration and functionality in mind. We use our own designs, and wouldn’t have it any other way.

This Haas side-mount tool changer features a servo-driven carousel that allows direct positioning to any tool in the carousel – no more indexing one pocket at a time. Faster positioning reduces cycle times during short machining operations, or when the carousel is not pre-staged for the next tool.

Standard 40 taper, 30+1 tools
Available for the HSK-A63 Spindle
50+1 side-mount tool changer available (optional)
Direct-positioning carousel for super-fast tool staging
Fast tool changes shorten cycle times on every tool change
Pocket Tool Table in the control allows complete control over the tool changer
Identify tools as LARGE to leave adjacent pockets empty
Identify tools as HEAVY to slow tool changer motion

Chip Management

At the heart of the VC-400’s chip management system is a wide belt-type chip conveyor positioned in the center of the machine, directly under the spindle. The steep walls of the interior enclosure easily funnel chips to the conveyor.

The conveyor discharges chips at the height of a full-size industrial barrel. Washdown nozzles mounted in the ceiling are fed by a separate coolant pump, and allow you to direct coolant flow to areas where chips may gather, to further enhance chip evacuation.

Automatic Probe Riser (Optional)

An automatic probe arm stores the tool setting probe in a protective compartment during machining operations. When the tool probe is needed, an M104 code activates the automatic probe arm to lift the probe and lock it into place. When probing is complete, an M105 retracts the probe to its protective compartment.

Included with the Wireless Intuitive Probing System (WIPS) Option
Programmable with M-codes for in-process tool inspection
Dedicated page on the Haas control for manual operation
Probe remains free of chips and contamination in the work envelope

Stepped Base and Column

The stepped base and column design of the VC-400/SS, where one X-axis linear guide rail is on a different horizontal plane than the other, increases the rigidity and stability of the spindle-head column assembly. With hydraulic pallet clamping and the stepped base/column design, the machine is very rigid, all the way to the top of travel!
