CNC-machined components, optical fixtures, and medical instruments require surface cleaning that removes cutting fluids, polishing compounds, and particulate contamination without affecting dimensional tolerances or surface finish. The Soner SE-55L precision CNC ultrasonic cleaner addresses this with 28/40 kHz dual-frequency cavitation-28 kHz for removing cutting oils and coolants from machined surfaces and 40 kHz for gentle cleaning of polished finishes, optical coatings, and delicate components.

With 900 watts of ultrasonic power and a 1500W heater maintaining up to 80 degrees Celsius, the SE-55L handles batch cleaning of machined brackets, optical mounts, surgical instruments, and small mold inserts. The 500 x 350 x 300 mm tank accommodates production batches without the floor space and power requirements of larger units. The dual-frequency capability means one machine replaces two separate cleaning systems-operators switch between frequencies via the digital control panel without changing tanks or solutions.

Unlike manufacturers that outsource transducers, Soner produces its own piezoelectric ceramics, ultrasonic transducers, and digital generators in-house. For precision applications where cavitation uniformity directly affects surface quality, this vertical integration allows frequency matching and acoustic optimization between the transducer system and the stainless steel tank-resulting in consistent, repeatable cleaning across every batch.

As a core model in the Soner Industrial Ultrasonic Cleaner range, the SE-55L brings precision dual-frequency capability to facilities that need both heavy degreasing power and surface protection. Explore the full series from 40L to 1500L.

The following models are also available in this product category:

28/40 kHz Dual-Frequency for Heavy Degreasing and Precision Surface Cleaning

28kHz for removing cutting oils, coolants, and polishing compounds from freshly machined surfaces. 40kHz for gentle cleaning of optical coatings, polished finishes, and delicate components. Switch via digital panel without changing solutions.

900W Controlled Ultrasonic Power

Sufficient power for batch cleaning of machined parts without the excessive cavitation that can damage delicate surfaces. Variable power control (0-100%) lets operators fine-tune cleaning intensity per part type.

1500W Heated Tank with Precise Temperature Control

Temperature control is critical for precision cleaning. 1500W heating maintains stable solution temperature within +/- 2 degrees, ensuring repeatable cleaning results batch after batch.

Compact Footprint for Lab Installation

Fits on standard lab benches or mobile carts. Designed for installation in metrology labs, QC inspection stations, and cleanroom ante-rooms where floor space is limited.

Surface Cleaning for Optical Components

The SE-55L functions as an optical surface cleaning bath when configured at 40 kHz with reduced power (20-40%) and mild surfactant solution. The gentle cavitation removes particulate contamination without damaging optical coatings or polished precision surfaces.

CNC Machining & Metal Fabrication [PRIMARY]

The SE-55L serves as a machined parts degreasing tank for freshly machined components before dimensional inspection, coating, or assembly. Remove cutting oil, coolant residue, and metal chips from bores, threaded passages, and complex geometries. A 40 kHz frequency protects machined surface finishes.

Optical Component Manufacturing

Clean optical mounts, fixtures, lens holders, and precision mechanical assemblies. 40kHz gentle cavitation removes particulate contamination without damaging optical coatings or polished surfaces. Ideal for pre-assembly cleaning of optical subassemblies.

Medical Device Component Cleaning

Clean surgical instrument batches, implant fixtures, and medical device components before sterilization or packaging. SUS304 tank surfaces do not cross-contaminate between batches. Digital timer and temperature control enable repeatable, documented cleaning cycles.

• Precision fixture and basket customization-design cleaning baskets and component holders matched to specific CNC workholding, optical mounts, or surgical instrument geometries.

• Custom frequency and power optimization for precision applications-fine-tune 40 kHz cavitation intensity, transducer layout, and power delivery for optical component cleaning, medical device surface treatment, and CNC part finishing requirements.

• Cleanroom-compatible configuration-sealed solution systems and stainless steel surface treatment for ISO Class 7+ cleanroom ante-room installation.
