Engraving refers to a cutting work technique, which is mainly used for decoration or labelling on surfaces of different materials using an engraving tool which is made of solid carbide in most cases.

This formula is used to calculate the machining time from the total table feed length and the table feed per minute (feed rate). Example of finishing a block of FC200 cast iron to have a flat surface of: Width = 150 mLength = 250 mmFace milling conditions used: Feed per tooth (fz) = 0.35 mmNumber of teeth (z) = 12Spindle speed (n) = 200 min-1Cutting speed (vc) = 120 m/minFace mill diameter (D1) = 220 mmIn this case, the table feed per minute (vf) and the total table feed length (L) are:vf = 0.35 × 12 × 200 = 840 mm/minL = 350 + 220 = 570 mmSubstitute these values into the formula: Tc = L ÷ vf = 570 ÷ 1120 = 0.679 (min) × 60 = 40.74 (sec)The machining time (Tc) is approximately 40.74 seconds.

Implement your ideas with the High-Z engraver by labeling workpieces or applying great decorations to your desired objects. It doesn’t matter if you would like to engrave photos or 3D lithophanes. Combining our engraving machines with our rotation axis and other accessories you have nearly unlimited possibilities in making CNC engravings.

The electric-engraving is related to EDM (electrical discharge machining) and welding. Here, a metal pin acting as an anode is made to oscillate to the cathode when current is applied. The cathode here is the material that is also wired accordingly to the engraving module. The current flowing between the cathode and anode burns the material at the point to be engraved. The oscillation of the engraving pin is caused by the interaction between the magnet armature and an electromagnet. The disadvantage is that you can only engrave conductive materials. The advantage is easily recognisable engravings on hard metals or HSS steels such as saw blades, milling cutters and other tools.

This was before industrialisation and the consequent forthcoming mechanisation of most craft, a simple craft operation. It had no rotating but stationary tools for engraving. Therefore, today, there are different types of engraving.

A DIN standard does not yet exist for the definition. However, it identifies a specific machining process for decorating or labelling of objects.

Today, engravings are made with manual engraving machines or with CNC engraving machines. The CNC engraving machine processes the milling paths which the CAD-CAM Software creates from the drawing and transmits to the control device. The entire engraving is computer-based and less error-prone than the manual engraving. The Reproduction with a CNC machine is quicker and more precise than using a manual engraving device. It is also worth mentioning that you don’t have to stand by the workpiece during the engraving. In the meantime, you can do other work which is significant for increasing your production.

This engraving-technique was developed with the introduction of mechanical equipment. A tool called Engraving or Milling Graver (usually single-edged without cutting angle and clearance angle at the cutting edge) is brought in the rotation and immersed in the material to be engraved to remove material (usually only a few hundredths of a millimetre). Materials with different coloured layers (engraving plastics, chrome-plated brass plates etc.) incur as multicoloured engravings for signs etc.

This formula is used to calculate the cutting speed from the spindle speed and the outer diameter of the cutter. Example: Cutter diameter (DC) = 100 mmSpindle speed (n) = 400 min-1In this case, the cutting speed (vc) is approximately 125.6 m/min.

This formula is used to calculate the table feed per minute (feed rate) from the feed per tooth, the number of teeth, and the spindle speed. Example: Feed per tooth (fz) = 0.2 mm/toothNumber of teeth (z) = 8Spindle speed (n) = 600 min-1In this case, the table feed rate is 960 mm/min.

In this technology, a fixed diamond is used as a scoring tool to carve the surface of metals, for example, a few hundredths of a millimetre. Inscriptions, decorations, ornaments and signs on metals such as copper, silver, brass, steel, stainless steel or glass and stone can be created.

Also suitable for engraving are grinding pins with diamond dust stocking for glass engraving and metal engraving, in which case the surfaces are roughened only.

This formula is used to calculate the net power required for face milling based on the depth and width of cut, the table feed per minute, the specific cutting force, and the machine efficiency. Example of calculating the net power required to cut tool steel with: Depth of cut (ap) = 5 mmWidth of cut (ae) = 70 mmTable feed per minute (vf) = 300 mm/min Other conditions: Specific cutting force (Kc) = 1800 MPaMachine efficiency (η) = 80% (0.8)Cutting speed (vc) = 80 m/minCutter diameter (DC) = 250 mmNumber of teeth (z) = 16 In this case, first you calculate the spindle speed (n) and then the feed per tooth of the cutter (fz). Spindle speed (n) = 1000・vc ÷ π・D = (1000 × 80) ÷ (3.14 × 250) = 101.91 min-1Feed per tooth (fz) = vf ÷ (Z × n) = 300 ÷ (16 × 101.91) = 0.184 mm/toothSubstitute the above into the formula: Pc = (5 × 70 × 300 × 1800) ÷ (60 × 106× 0.8) = 3.937 kwThe net power required for face milling (Pc) is approximately 3.94 kW.

This page introduces formulas for calculating basic parameters necessary for face milling. The figures obtained from the calculation are for reference only. The conditions for machining depend on the machine tool you are using. Use the optimal conditions according to your actual machining circumstances.

In classical hand-engraving, a tool with a wooden handle is used. This usually slightly curved tool has a very sharp blade with which it is possible to score the most materials except glass. The conventional hand engraving is still often used when thinning letters in gravestones etc., for example when pure handwork is required.

This formula is used to calculate the feed per tooth from the table feed per minute (feed rate), the number of teeth, and the spindle speed. Example: Table feed per minute (vf) = 450 mm/minNumber of teeth (z) = 10Spindle speed (n) = 600 min-1In this case, the feed per tooth (f) is 0.075 mm/t.

The most modern of all techniques today is the laser-engraving in which the material to be engraved is evaporated by the hot laser produced by the high temperatures of the laser beam at the machining point. By using the laser temperature control, it is now also possible to “engrave” semitones.
