How CNC Punch Presses Works :

The CNC machine is basically programmed to move a sheet of metal in an x and y direction so as to accurately position the sheet under the machine’s punching ram ready to punch. The processing range for most CNC punch presses is 0.5mm to 6.0mm thick in a range of materials including steel, zinc, galv, stainless steel and aluminum.

A typical CNC turret punch has a choice of up to 60 tools in a "turret" that can be rotated to bring any tool to the punching position. A simple shape (e.g., a square, circle, or hexagon) is cut directly from the sheet. A complex shape can be cut out by making many square or rounded cuts around the perimeter. As a press tool requires a matching punch and die set, there are two corresponding turrets, above and below the bed, for punch and die. These two turrets must rotate in precise synchronisation and with their alignment carefully maintained.

The choice of hole punched can be as simple as a circle or rectangle right through to special shapes to suit a specific cut out design. By using a combination of single hits and overlapping geometries, complex sheet metal component shapes can be produced. The machine may also punch 3D forms such as dimples, and electrical knockouts etc on either side of the sheet.

Some of the advantages using Charta’s CNC Punch Services include:

 

CNC Punching machines have lower capital cost than lasers and they do not use electric power to nearly the same extent (nor do they have the need for various cutting gases).

Ability of Producing complex 3D characteristics precisely on sheet metal, making counter-sunk or extruded holes, louvers.

CNC punch presses can process shiny sheet metals like brass, aluminum etc. faster than Laser Cut machines.

CNC punch presesss are faster for those times when your projects require repeated shapes (circles, triangles, squares) from a wide variety of stock material and a fast turnaround.

CNC Punch Process is Fast and accurate over and over again without variation.

FIBER LASER CUT

Charta utilizes 2 1kw laser machines, capable of handling our customer's precision Laser Cutting needs, from prototype through large-scale production. Our machines utilize advanced Fiber cutting technology. Charta strives to ensure fast, precise component fabrication and servicing for our customers

Laser Cutting is an advanced process that produces exact cuts in virtually any shape, at any angle, and through materials that would be destroyed by contact cutting tools Briefly, fiber laser light is created by banks of diodes. The light is channeled and amplified through fiber optic cable similar to that used for data transfer. The amplified light, on exiting the fiber cable, is collimated or straightened and then focused by a lens onto the material to be cut.

Creation of the light is 200% more efficient than via a traditional CO2 laser, and delivery is far simpler, with no expensive optical mirrors. The focusing lens, unlike on a conventional CO2 laser machine, is sealed in the cutting head and thus not a consumable item.

 
 

The benefits of a true fiber laser source include:

No moving parts or mirrors in the light-generating source, unlike a conventional CO2 resonator or disk laser. This has a distinct advantage in terms of reducing maintenance requirements and operating costs.

Much higher electrical efficiency, resulting in considerably lower running costs. A 3 kW fiber machine uses one third of the power of a 4 kW CO2 machine of average across-the-board performance.

Higher speeds when cutting materials thinners than 10 mm. Compared with the same 4 kW CO2 machine, the fiber laser is three times quicker cutting of 1 mm mild, galvanized, or stainless steel and twice as fast when cutting 2 mm

An ability to cut reflective materials without fear of back reflections damaging the machine. This allows copper, brass, and aluminum to be cut without problems.

50% longer servicing intervals and 50% lower servicing costs.

SolidWorks and Catia modeling software is used to create a solid model of the design. This allows us to ensure that all designs are dimensionally sound and properly mate to ancillary components before fabrication, saving time and cost during manufacturing. Chatra complete any project from prototype to medium volume fabrication with fast turnaround and a strong focus on customer service.

ELECTROSTATIC POWDER COATING

In Chatra Powder Coating Services we're dedicated to providing our customers with the highest quality powder coating services available. Our powder coating services are applicable to a wide range of materials and substrates such as aluminum, galvanized, magnesium, mild and stainless steel. Our 2 mono-rail painting conveyor can powder coat components in variety of weight, shapes, and dimensions in very short time compare to our competitors. Another service that chatra provides for its costumers is the application of any type of paint branding to all parts in any desired shape and dimension.

Wet painting is a traditional treatment method by which a pigment in any water-based or solvent-based paint is sprayed onto the surface of a part. Common applications of wet paint include automotive exteriors and extremely large or heavy items.

When superior performance is required, powder coating as a finishing process can replace traditional wet painting.

 
 

Many concerns or issues associated with wet paint finishing are eliminated or minimized with they generally fall under four categories:

Performance – Powder coatings are more durable and more resistant to corrosion, chemicals and weather than liquid coatings. Powder-coated surfaces are more resistant to chipping, scratching and other such wear due to the thermal bonding process during curing. Unlike wet paint, powders also don’t run or drip, providing a more uniform coating than liquid paint.

Operational Costs – Powder coatings are cheaper and can cover more area than most other organic finishes, translating to lower material costs than wet painting processes. Because they lend themselves well to automation, powder coatings can also reduce costs related to operational labor, as minimal operator training and supervision are required for a powder line. Compared to wet paint processes, operational cost savings using powder coatings can also be realized in less waste produced, lower energy costs, reduced disposal costs and less rework due to lower reject rates.

Safety – Wet paint is flammable, carcinogenic and full of volatile organic compounds (VOCs). These chemicals can be hazardous to plant/shop personnel if not handled properly. Powder coatings, on the other hand, are generally VOC-free materials and contain no solvents, meaning they do not involve the potentially harmful chemicals typically found in a wet spray project. Although powder coating materials can combust in a very narrow concentration of powder and air, their lack of solvents or VOCs means almost none of the short-term and long-term health or fire workplace threats associated with wet painting.

Environmental – VOCs in the wet painting process are also among industrial pollution concerns. Because powder coatings contain no solvents and emit negligible, if any, polluting VOCs into the atmosphere, they are more environmentally friendly than their wet paint counterparts. Moreover, powder coating is a clean process: powder overspray can be retrieved and reused, and unused powder can be reclaimed and returned to a hopper for recirculation through the system, with negligible waste. Plus, most powder coating materials are considered landfill/ non-hazardous materials. Powder coatings meet all Environmental Protection Agency requirements for air and water pollution control.
