Buehler EcoMet 30 Semi-Automatic Grinder Polisher for Metallographic Sample Preparation

The Buehler EcoMet 30 Semi-Automatic grinder polisher bridges the gap between manual operation and full automation. It adds a touchscreen interface, programmable force application, and stored method programs to the proven EcoMet 30 platform — giving labs consistent, repeatable grinding and polishing results for low- to medium-volume metallographic sample preparation without the cost of a fully automated system. Available in single and twin platen configurations.

EcoMet 30 Semi-Automatic Grinder Polisher Features & Benefits

The semi-automatic EcoMet 30 adds instrument-controlled parameters to the manual EcoMet platform. Where the manual model relies on operator feel, the semi-auto holds force, speed, and time to set values — reducing variability between runs and between operators.

Touchscreen interface: 7″ colour LCD for parameter entry and program recall — faster setup than membrane controls, lower training overhead than manual dial adjustment
Force application: Central and individual specimen force applied by the powerhead — eliminates hand pressure variability, the primary source of inconsistency in manual grinding and polishing
Stored programs: Save and recall multi-step methods by material or process — any operator reproduces the same parameters without re-entering values
Platen compatibility: Accepts 8″, 10″, and 12″ (203–305mm) platens — select size to match sample dimensions and optimize grinding disc and polishing cloth cost per run
Burst dispensing: Compatible with up to 3 automatic Burst units for metered diamond suspension delivery at each polishing step — operators step away without sacrificing consistency
Double bowl (twin): Twin configuration’s double bowl allows simultaneous setup of grinding and polishing steps — no media swap required between steps
Rinse and spin: Integrated bowl and cloth rinse between steps — reduces cross-contamination in multi-step workflows
Consumables: Compatible with the full range of Buehler polishing cloths, grinding discs, silicon carbide papers, and specimen holders

EcoMet 30 Semi-Auto Configurations

The EcoMet 30 Semi-Auto is available in single and twin platen versions. Both share the same touchscreen, force control, and stored program capabilities.

EcoMet 30 Semi-Auto Single — choose this if:

One operator runs samples sequentially through stored grinding and polishing programs
Force-controlled preparation is required but parallel processing is not
Lab space or budget limits a twin-station setup

EcoMet 30 Semi-Auto Twin — choose this if:

Multiple operators share the machine — each platen operates independently with its own stored program
Grinding and polishing steps run simultaneously: one platen on SiC paper, one on polishing cloth
The double bowl eliminates manual media swaps between steps — faster multi-step throughput
Medium-volume workflows require consistent throughput without stepping up to the AutoMet 250
