Thermal Deburring (TEM) Machines
TEM (Thermal Energy Method) deburring machines deliver fast, repeatable burr removal – especially for internal cross-holes and complex channels. iTEM systems are developed and manufactured by ATL (Germany).

Thermal Deburring - repeatable burr removal and clean parts
How TEM deburring works
Thermal deburring (TEM/Thermal Energy Method) removes burrs using a controlled oxygen - fuel gas mixture inside a sealed chamber. The short thermal reaction oxidizes burrs first, including burrs in internal cross-holes and intersecting bores, while the base material remains protected by the very brief exposure.

Machine types
iTEM TEM deburring machines are available in multiple chamber sizes and automation levels. Core models include iTEM 320NG and iTEM 400 Plus (5-station systems) for most applications, while iTEM 1200 LC is a specialized solution for rocker arm shafts. Compare configurations to choose the right system for your parts and throughput.

Typical applications
Example: hydraulic manifolds - TEM removes burrs from cross-holes and internal passages in a single cycle, improving functional reliability and reducing manual rework.
TEM is commonly used for automotive components, precision engineering parts, medical devices, and die-cast components where internal burrs are difficult to access.
Materials compatible with TEM
Our thermal deburring machines effectively process a broad range of metals and selected polymers, including:
- Metals: steel, stainless steel, cast iron, aluminum, brass, zinc die-cast parts
- Polymers (application-dependent): PA, PE, PTFE, PUR, PMMA
- Injection molded parts: depending on geometry and combustion behavior
- Note: magnesium and titanium may require restrictions based on combustion characteristics
Key benefits for production
- Complete burr removal in one cycle (internal & external edges)
- Effective for cross-holes, internal channels, and hard-to-reach features
- Short cycle times for high-throughput production
- Repeatable results with stable process parameters
- Low tool wear and reduced manual deburring effort
- Supports consistent cleanliness for downstream assembly

What Our Customers Say
“This machine has helped us to increase our manifold deburring throughput, part cleanliness, and relieve our colleagues from the stress and strain caused by the manual deburring process which we previously used.”
Rich McGrath
Global Manufacturing Operations Support Manager Sun Hydraulics
“We have tested tiny parts from tool steel and housing parts from aluminium, with an excellent result. A good process for hidden burrs.”

FAQ
Most frequent questions and answers
Thermal deburring (TEM / Thermal Energy Method) is ideal for parts with internal burrs, intersecting bores, cross-holes, and complex channels – such as hydraulic manifolds, valve bodies, die-cast components, and precision machined parts. It is commonly used on steel, stainless steel, cast iron, aluminum, and brass, and on selected thermoplastics (application-dependent).
Cycle time depends on part geometry, burr size, and loading/automation. The thermal reaction itself is very short, while the total machine cycle is typically in the range of seconds to a few minutes. For production planning, we recommend a quick part review to estimate throughput for your application.
TEM is a deburring process designed to remove burrs without mechanical contact. In most cases it does not change the functional surface finish or dimensions of the base material; the main effect is at the burr. The final result depends on material, burr location, and part cleanliness – share a sample part for confirmation.
Materials with high reactivity or specific combustion behavior – such as magnesium and titanium – may require restrictions or special process conditions. Material compatibility depends on alloy, geometry, and safety requirements, so we review material and part design before processing.
Yes. Sample testing is free to confirm burr removal, cleanliness, and feasibility. Shipping to and from our facility is arranged and paid by the customer. Please include material details, burr location (e.g., cross-holes/internal channels), and your target throughput.
Parts should be clean and dry, with burr locations identified if possible. Pack parts securely to avoid damage and include material specification, drawings (if available), and desired outcome (burr-free edges, cleanliness level). Contact us and we’ll provide shipping instructions for your location.
We provide global service and application support. ATL service technicians are based in Poland, Germany, China, and the USA, supporting installation, commissioning, maintenance, and process optimization for iTEM thermal deburring (TEM) machines.
