Quartz · crystal blanks and rod features
Cut quartz crystal blanks into parallel slices, or use single-wire cutting for individual profiles and internal openings in quartz rods. Choose the machine from the blank dimensions, cut direction and finished-part drawing.
Identify the material and drawing
For quartz crystal wafer cutting, the drawing should identify the material, blank dimensions, cutting plane and inspection datums. For piezoelectric parts, also specify the crystal orientation and axis convention. Keep enough stock for the required lapping or polishing operation.
Supply dimensions, material identification and the available clamping surfaces. Distinguish crystal slicing from a rod feature or an individual profile.
State the target slice thickness, quantity, cut direction and allowance for later material removal. Identify which surfaces are inspection datums.
Measure slice thickness, inspect the edges and surface, and check the stock remaining for finishing.
The drawing should state its axis convention. See the technical reference on quartz crystal orientation for background.
A multi-wire web cuts several parallel slices in one setup. SOM200 is intended for laboratory and pilot batches. SOMI-430 uses inverted feed and accepts longer blanks within its narrower cross-section limits.
Check the mounted blank against all three machine-capacity dimensions. Leave clearance for the fixture and the table movement.
For an internal opening or profile in a quartz rod, send the drawing for an SVO-40 application check. The drawing needs to show the cut path, wire entry and clamping surfaces.
The wire needs access to the internal cut. Starting-hole preparation, minimum opening size and remaining wall thickness must be settled before the cutting trial.
Select by the operation
SOM200 is a compact multi-wire machine for small batches of parallel slices. Its listed materials include quartz and piezoelectric crystals.
Listed capacity: 200 × 200 × 200 mm, with a 0.3–12 mm slice range. Use a sample cut to establish the settings and thickness variation for your quartz blank.

SOMI-430 feeds the workpiece upward into a two-spindle wire web. It accommodates longer blanks than SOM200, with less available width and height.
Listed capacity: 430 × 160 × 150 mm, with a 0.3–3 mm slice range. Send the quartz grade and fixture drawing with the enquiry.
View SOMI-430SVO-40 uses a vertical spooled-wire arrangement for individual cuts and CNC profiles. Quartz rod internal cuts are assessed from the drawing, including wire access and workholding.
Listed capacity: 400 × 400 × 300 mm. Minimum slice thickness and internal-feature dimensions are application-specific.
View SVO-40| Model | Listed workpiece envelope | Listed slice range | Cutting task |
|---|---|---|---|
| SOM200 | 200 × 200 × 200 mm | 0.3–12 mm | Small-batch parallel crystal slices |
| SOMI-430 | 430 × 160 × 150 mm | 0.3–3 mm | Inverted-feed parallel slicing |
| SVO-40 | 400 × 400 × 300 mm | Confirm for the application | Individual cuts, profiles and internal openings |

Record the conditions and the result
For quartz rod cutting, include the full rod and feature dimensions in the enquiry. Record the wire specification, fixture and cutting settings alongside the sample measurements so the result can be assessed against the proposed production job.
Use the precision slicing checklist to prepare your acceptance criteria. For subsequent finishing, see grinding and lapping equipment.
Provide the required cutting plane, crystal-axis reference and the datums used to position the blank. Crystal-orientation measurement is a separate requirement to specify with the job.
No. Resonator acceptance also depends on the specified material, crystal orientation, finishing and component tests. A listed cutting range is not an electrical-performance specification.
Send the opening size, internal corner radii, remaining wall thickness and proposed wire-entry route. These details determine whether the cut can be made and how the rod can be held.
Compare the entire workpiece envelope: SOM200 offers 200 × 200 × 200 mm, while SOMI-430 offers a longer but narrower 430 × 160 × 150 mm envelope. Then check the slice range, mounting arrangement and required operating method.
Free sample cutting
Include material identification, dimensions, orientation reference, target slice thickness or feature geometry, finishing allowance and inspection criteria. State whether you need parallel slices, a profile or an internal opening.
