What Are Engravers?
Engravers are devices that perform marking by applying pressure to the target with a plate.
This section introduces the types, principles, and characteristics of engravers.
Engraver Types
Engravers come in various different types and are used separately to match factors such as the target's material and appearance and the engraving purpose.
Hand Engraving
The stamp is held by hand and is struck from above with a hammer. The characters that are created are deep and solid, so this type of engraving can be used to create text that is resistant to deterioration stemming from deep scratches and friction.
It is suited to engrave materials like aluminum, steel, and brass, as well as heavy items that are difficult to move.
Stamp Engraver
Single-use engraving of a few characters or digits is performed by setting individual stamps in the holder. This method can be used to engrave many neatly aligned characters in a short period of time. This tool can also be attached to a press or roller. It can be used for nameplates and other parts made of materials such as aluminum, steel, stainless steel, brass, and resin.
Stamp Engraver (Numbering)
This method uses dials to select the numbers that will be engraved. This tool can also be attached to a press. This method is used to engrave consecutive numbers, model numbers, serial numbers, and lot numbers. It is suited to engrave materials like aluminum, steel, and brass, as well as heavy items that are difficult to move.
Roll Marker
Roll markers can be used to engrave curved surfaces with multiple digits per operation by aligning stamps horizontally in a ring.
Stamp Engraver (Press)
Similar to stamping, targets are engraved by using a spring-loaded stamp that hits the surface of the material.
Stamp Engraver (Chuck)
This is an engraver that can mark multiple faces of hexagonal and octagonal targets at the same time. It is best suited for targets with multiple faces such as couplings and bolt nuts.
Pin Marking (Dot Peen)
The pin, which is known as the marking pin, is driven with air pressure or electricity to engrave the surface of the target by marking it with groups of dots. This method is also known as pin stamping. It excels at engraving hard materials such as uneven metal surfaces and composite resins. Engraving is possible regardless of the surface condition (wet, dusty, etc.) of the target.
Electric Engraving Pen
The sharp tip, which is known as the bit, is rotated at high speed (2,000 to 40,000 rpm) to engrave the target.
The work is mainly performed by hand, so there are limits on what industrial fields electric engraving pens can support. However, many different types of bits exist, and different materials can be marked just by switching the bit.
