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.

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. Select the appropriate US, EU, UK or AU plug according to the destination country.
