CNT has been able to build machines that our competition chose not to build. Once we understand your manufacturing process and production goals, we can design a solution to fit them.
We integrate SolidWorks and finite element analysis (FEA) into the design and development of our solutions to simulate the machines and minimize deflection. We adopt laser tracking to certify positional accuracy. CNT can also incorporate UV curing capabilities into your machine, if your application requires it.
Long Table for Machining Curtain Wall and Extrusions
In 1999, CNT built the first of several machines designed to drill and mill 30-foot long aluminum extrusions for pre-engineered commercial building exterior wall coverings, known as curtain walls. (This operation was previously being performed by individuals with drills and tape measures. The milling was done separately on a manual Bridgeport with 30 inches of table travel, requiring frequent indexing of the part.) With the 30-foot bed, pivoting head, automatic tool changer and alcohol/oil coolant system, the CNT machine provided a single-step, automated solution.
12-foot-long Table for Small Parts Production
In 1999, CNT built the first of several machines designed to drill and mill aluminum extrusions for a variety of applications, including door & window frames, aerospace and transportation industry components, lighting enclosures and wall systems. (These operations had typically been performed by individuals with drills and tape measures. The milling was done separately on a Bridgeport with limited table travel, requiring frequent indexing of the part.) With a 12-foot bed, 24 vise clamp positions, eight pop-up position stops, a pivoting head, 16-position automatic tool changer and alcohol coolant system, the CNT machine provides a single-step automated solution. On the machine pictured here, the vise deck is removable to allow access to a fully functional vacuum grid bed for machining aluminum sheet material. The vise deck is removed using four lifting rings and is easily and accurately reinstalled using location pins.
Bar Stock and Sheet Goods Metalworking
CNT Motion has been producing large-work-area metalworking CNC Router/Mills as a cost-effective solution for milling large, light-gauge to medium-thickness steel, aluminum, copper, brass and other metal bar/plate. Many of our customers have found that our CNC Router/Mills are ideally suited for their specific applications, providing greater flexibility, higher speeds and larger work areas than traditional vertical machining centers.
Stair Stringer and Tread Machine
CNT has been building machines for cutting stair treads for a number of years. The machine has two individually programmable X-axes, each attached to a Z-head for mirror-image and split-head machining to optimize material for the best possible yield. A custom software program allows the operator to pick material type and thickness, rise and run, style of stringer (box, open, horse cut, winder, etc.) and end cuts.
Custom Table and Fixturing System for Fence Manufacturing
Since 1994, CNT Motion Systems has been manufacturing machines for the fence industry. Our fence machines feature special air-activated, self-centering clamps to hold PVC, wood or aluminum fence posts ranging from 1-8" in width. The two-, four- and eight-spindled configurations deliver high production for this efficient, affordable solution.
Conveyor Feed-through Parts Machining
This machine was designed to be installed inline with an existing panel processing cutter. The pre-cut parts are pushed into the machine from a stacker where an optical sensor activates the ball screw clamping of the servo-driven, conveyor-style belt feed. The part is moved at a high speed to the next optical sensor located 56" from the in-feed where it is oriented to begin machining. The X-,Y-,Z- and W-axes machine the top profiles before the part is advanced by the conveyor belt system through the fixed (yet adjustable) Porter Cable slotting routers mounted at top and bottom.
Snowboards and Skis High-Production Manufacturing
This machine was one of four routers shipped to China for a CNT Motion customer who was setting up a new production facility for manufacturing snow boards and skis. The company, which bought two of these unique four-headed machines, came to us through their supplier of wood cores (also a CNT Motion customer). By producing four to eight boards at the same time, with a cycle time only minutes long, the company is producing hundreds of thousands of products a year. And, during their peak season, they’re running the machines 24/7!
Surfboard and Stand-Up Paddleboard Shaping Systems
Since 2000, CNT has been building machines for high-production surfboard and stand-up paddleboard (SUP) shaping. Incorporating a specialized support system, digitizing capability and industry-standard shaping software, this machine has enabled our clients to successfully pursue this challenging market using automation to boost both productivity and creativity.
Live Tooling Lathe Mill
The industry’s most powerful 4-Axis CNC foam carving and flatbed router delivers capabilities unavailable from traditional processes or lesser machines. This powerful machine's industrial strength, top-of-the-line features and unequaled precision enable you to expand your product offerings and broaden your market reach. Turn your imagination into reality by creating larger and more intricate pieces than ever before!
High-Production Wood, Plastics and Metal Machining
A renowned manufacturer of inspirational art, home decor and gifts has deployed two identical four-headed machines for 3-D high-resolution (4000 steps per inch/.0002) carving of various hardwoods — four to eight pieces at a time. To ease material loading/unloading, CNT Motion specially designed a custom 12'X4' front-loading table.
3-D Carving, Prototyping and Modeling
In 2003, CNT Motion Systems designed this 11' X 20' machine with four feet of Z-travel/clearance and a tilting spindle for Sage Cheshire, Inc. This California-based company has been providing services for many of the leading aerospace companies for more than 40 years. They offer prototyping and production services that utilize this CNC machining center’s unique size and flexibility. For more information about Sage Cheshire and their services, visit their web site at www.sagecheshire.com.
Profiling, Grooving and Polishing
In 1997, CNT Motion designed and built the first of five machines for a customer specializing in the management of water removal and sheet formation on all types of pulp and paper machines. Their unique process combines heat and air flow to remove moisture content from pulp. Currently, they have five CNT machines (three in the U.S. and two in the APAC region) used for profiling reinforced fiberglass plastic 2" tall, 4" wide and up to 35' in length. Once machined, 2" ceramic profiles are bonded to the material and (using the same machine) ground to within .002" tolerance over the entire length and then polished to a #5-8 finish.
Four-Axis Lathe/Mill with Live Tooling
This unique machine design best illustrates CNT Motion's ability to provide automation solutions to boost throughput and create a fully autonomous state-of-the-art composite fabrication facility. This machine was the centerpiece of a design that incorporated a CNC extractor feeding a CNC overhead auto-loader/unloader with part orientation and size identification, then feeding this lathe/mill unit, back to unloader and then, finally, to an out-feed conveyor.
CNC Routing (Our Base Machines)
The Servo-powered CNT-950 is our most affordable model and perfect for those new to CNC technology. It’s also a great second or third machine for manufacturers looking to expand their current production capabilities.
The CNT-1000 Series is a full-sized, servo-powered, high-performance machine designed for heavier applications, including nested-based fabrication of plastics, hardwoods, solid surface and non-ferrous metals.
