100W Pneumatic Jewelry Engraving Machine with Built-In Air Supply and Foot Pedal
100W Pneumatic Jewelry Engraving Machine with Built-In Air Supply and Foot Pedal Product Overview The HH-AT01 is a compact pneumatic impact engraving machine designed for jewelry engraving, surface texturing, fine carving and compatible stone-setting work. Its built-in air supply powers the pneumatic engraving handpiece without requiring a separate external air compressor, helping simplify setup and save valuable workbench space. Independent POWER and SPEED controls allow the operator to adjust the relative impact strength and stroke frequency according to the material, graver and task. The included foot pedal provides convenient hands-free activation while the operator guides the handpiece. The complete kit includes a pneumatic handpiece, foot pedal, six engraving gravers, six color-coded quick-change chucks and the necessary connection accessories. Key Features Built-In Air Supply The integrated air supply powers the pneumatic handpiece without requiring an external air compressor, providing a more compact setup for jewelry workshops. Adjustable Impact Controls Separate POWER and SPEED knobs allow the operator to adjust the relative impact strength and stroke frequency for different engraving and setting applications. Foot Pedal Operation The included foot pedal provides convenient hands-free activation, allowing the operator to concentrate on controlling the graver and workpiece. Pneumatic Impact Handpiece The handpiece produces rapid reciprocating impacts that drive the graver through suitable jewelry metals. It is an impact engraving system rather than a rotary grinding tool. Digital Setting Display The front digital display provides a clear reference for the selected relative operating setting. Quick-Change Tool System Six color-coded quick-change chucks and six engraving gravers are included, making it easier to organize and change tools for different engraving profiles. Compact Workbench Design With a main unit size of approximately 22 × 12 × 18cm, the machine fits comfortably into professional jewelry workshops, repair studios and training environments. Suitable Applications Hand engraving on jewelry metals Letter and decorative pattern engraving Surface texturing Stippling and matte effects Fine metal carving Metal inlay work Bead raising and compatible stone-setting preparation Jewelry repair and customization Goldsmith and silversmith work Jewelry engraving practice and training Suitable Materials Gold Silver Copper Brass Platinum Compatible jewelry alloys Suitable small metal components Important: Performance on hardened steel, titanium and other hard alloys depends on the material hardness, graver material, cutting geometry, machine setting and operator technique. Test the settings on scrap material before working on a finished piece. Important Function Clarification This product is a pneumatic impact engraving machine. It is not: A rotary flex-shaft tool A rotary grinding machine A laser engraver A CNC engraving machine An automatic pattern reproduction system A gemstone cutting machine All engraving movements and patterns must be manually guided by the operator.

Basic Operating Steps Place the machine on a stable, dry and level workbench. Confirm that the AC input rating is compatible with the local power supply. Install a properly sharpened graver into a compatible quick-change chuck. Connect the pneumatic handpiece and foot pedal to their corresponding ports. Turn the POWER and SPEED controls to their minimum settings. Switch on the machine and test it on scrap material. Press the foot pedal and gradually increase the POWER and SPEED settings until the desired cutting response is achieved. Release the foot pedal, return the controls to minimum and switch off the machine after use. Voltage and Plug Information AC Input Voltage: 100–240V. Select the plug type that matches the destination country when placing the order. A plug adapter changes only the physical plug shape and does not convert voltage. Always inspect the rating label on the supplied power adapter before connecting the machine. Safety Information Wear suitable eye protection during operation. Secure the workpiece in an engraving block, vise or suitable holding fixture. Keep your hands behind the cutting edge of the graver. Do not install or replace gravers while the machine is powered. Begin with low POWER and SPEED settings. Do not use damaged cables, tubes, plugs or handpieces. Keep the machine away from water and flammable or explosive environments. Do not cover the ventilation openings. Stop using the machine immediately if it produces smoke, a burning smell or abnormal noise. Keep children and untrained users away from the equipment. Frequently Asked Questions Does this machine require an external air compressor? No. The HH-AT01 has a built-in air supply that powers the pneumatic engraving handpiece. Is it a rotary engraving machine? No. It is a pneumatic impact engraving system. The handpiece moves the graver through rapid reciprocating impacts rather than rotary motion. What does the POWER knob control? The POWER knob adjusts the relative impact strength of the handpiece. What does the SPEED knob control? The SPEED knob adjusts the relative stroke frequency. The 0–100% value is a relative setting and is not an rpm rating. Can it be used for stone setting? It can assist with compatible stone-setting operations such as bead raising and certain setting preparation tasks. Results depend on the selected graver, material, settings and operator technique. Is it suitable for beginners? Beginners can use the machine, but proper graver sharpening, workholding and engraving techniques are required. Practice on scrap metal before working on valuable jewelry. Does the machine support 100–240V? Yes. The AC input voltage is 100–240V.
