OUR CNC PUNCHING
WORKING CAPABILITIES
Depending on both size and the complexity of the required parts, CNC Punching can be a more cost effective solution than Laser Cutting. It offers rapid processing speeds and low operating costs. The processing range for our Robofacturing and Manufacturing Partners punch presses is 0.5mm to 6mm thick in a range of materials including carbon steel, galvanise steel, stainless steel and aluminium, among others.
The choice of hole punched can be as simple as a circle or rectangle right through to special shapes and bespoke designs that suit customer demand.

HIGH SPEED AND ACCURACY
Generally run times are faster. CNC Punching suits larger volume productions because it can go up to 1000 punch strokes per minute.
INCREASED PRODUCTIVITY
Once a design has been chosen and created, it can be used over and over again. This repeatability increases productivity by removing technical and intensive manual processes.
LOWER COST
CNC Punching is one of the more economical manufacturing processes to produce simple forms. Also, it allows to optimize the use of the sheet metal, keeping the waste to a minimum. Along with all this, the whole process is automated, keeping the operator safe and providing a hazard-free environment.
EFFCIENCY
Can create entire parts in a single punch with a custom tooling. CNC Punching machines reduce the amount of waste that is produced whilst being fast and accurate. Our Robofacturing and Manufacturing Partners have an internal quality detector installed in many machines, when a deficiency is detected, the machine will stop punching to avoid any further wastage.

SURFACE FINISHES
STANDARD (AS MACHINED)
– Surface roughness Ra = 3.2 μm (micrometres). Roughness ISO grade N8.
– Available to all metals and plastics.
It is our standard and quickest finish option. Tool marks are visible. Sharp edges and burrs are removed upon request. The colour of the finish will be the natural colour of the material.
IMPROVED MACHINED FINISH
– Surface roughness Ra = 1.6 μm (micrometres). Roughness ISO grade N7.
– Available to all metals and plastics.
The surface roughness will be improved during the CNC machining process itself by slower machining processes. Tool marks are visible, but less obvious. Sharp edges and burrs are removed upon request. The colour of the finish will be the natural colour of the material.
ANODIZING TYPE II OR DECORATIVE
– Corrosion-resistant finish.
– Masking requirements to be indicated in the technical drawings.
– Available to all aluminum materials.
The Type II anodizing process improves the aluminum properties increasing corrosion resistance and producing a uniform finish. ROBOFACTURING3D offers clear or black anodize coating, as well as it can be dyed in multiple colours (available upon request). Standard coating thickness 0,02 to 0,03 mm.
ANODIZING TYPE III OR HARDCOAT
– Corrosion-resistant and wear-resistant finish.
– Masking requirements to be indicated in the technical drawings.
– Available to all aluminum materials.
The Type III anodizing process produces a thicker layer than Type II, adding a wear-resistant properties in addition to the previous corrosion-resistant indicated in Type II. You can find a clear or black anodize coating. Standard coating thickness 0,02 to 0,07 mm.
BEAD BLASTING
– Different grits depending on the size of the bead.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.
Bead blasting is often used in creating a smooth uniform matte or satin surface finish on machined parts. It is used mainly for visual appearance. Tool marks and sharp edges are removed. It is a very useful surface treatment on parts manufactured by die casting or to improve the surface finish of the part before applying a secondary surface finish, for example anodizing.
ELECTROPOLISHING
– Surface roughness Ra = 0.8 μm (micrometres). Roughness ISO grade N6.
– Improve the appearance and the corrosion resistance.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.
Electropolishing improves the appearance and the corrosion resistance by reducing the surface roughness. The colour of the finish will be the natural colour of the metal.
POWDER COATING
– Excellent corrosion-resistant and wear-resistant finish.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.
Powder coatings can produce much thicker coatings than conventional liquid coatings. Also, powder coated parts have fewer appearance differences than liquid coated parts between horizontally coated surfaces and vertically coated surfaces. Curing time is significantly faster with powder coatings. ROBOFACTURING3D offers a clear or black powder coating, but also can be finished in multiple colours (available upon request).
BRUSHING
– Surface roughness Ra = 0.8 μm to 1.6 μm (micrometres). Roughness ISO from grade N6 to grade N7.
– Polishing the metal to improve the appearance.
– Masking requirements to be indicated in the technical drawings.
– Available to all metals.
Brushing the metal will allow a satin finish. It allows to improve the surface roughness of the part but does not improve corrosion resistance since it does not modify the mechanical properties of the metal. The colour of the finish will be the natural colour of the metal.
CHEM FILM (CHROMATE CONVERSION COATING)
– Improve the corrosion resistance and maintain the conductivity properties.
– Masking requirements to be indicated in the technical drawings.
– Available to aluminum and alloys.
A chemical coating will be applied to the metal to improve the corrosion resistance. It can be used as a base for paint. The colour of the finish ROBOFACTURING3D offers is clear, yellow or golden.
TOLERANCES
SHEET METAL MACHINING
For sheet metal features of size (length, width, height, diameter) and location (position, concentricity, symmetry) apply tolerances as follows if:
– Just a 3D file is supplied;
– A technical drawing is supplied but no tolerances specified;
– And no tolerances are specified throughout our quote platform.
Forming and bending: ± 0.50mm
Linear dimensions excluding locations to bends:
| 0 Decimal Places 1 Decimal Place 2 Decimal Places |
