SUMITOMO ELECTRIC AC1135U small lathe for turning small parts

SUMITOMO ELECTRIC AC1135U small lathe for turning small parts

Core technical characteristics of the brand

AC1135U adopts a new type of PVD multi-layer coating with ABS TECH and special surface treatment, with a three-layer functional structure:

TiCN anti adhesion layer: excellent anti adhesion, suppresses material sticking under low-speed precision machining conditions, and maintains high machining surface quality.

TiAlN anti chipping layer: ultra-fine grain with high toughness, suppresses sudden chipping, and has high processing stability.

High adhesion technology: strengthens the adhesion between the coating and the substrate, reduces coating peeling;

Smooth and glossy surface treatment: suppresses micro chipping and reduces material adhesion.

Matrix performance: High hardness HRA, flexural strength TRS=3.8GPa, high-precision positioning for small piece processing. Compared with Sumitomo's existing grades AC1030U, AC530U, and metal ceramic T2100Z, AC1135U focuses more on continuous/semi intermittent processing of stainless steel, taking into account steel parts.

Chip breaking groove system

The prefix M (such as MEFF, MEFC)=negative tolerance tool tip radius

Main groove types and selection

Applicable working conditions for slot positioning

MESI (the first choice) is the preferred universal precision machining groove type walking machine/automatic lathe, with excellent chip removal under a wide range of feed depth, solving the problem of long chips, and suppressing vibration patterns, burrs, and surface defects

MESL sharp cutting edge groove type cutting edge is sharper, pursuing excellent surface quality, suitable for wide condition precision machining

MEFF precision machining groove type with small margin precision turning, minimal cutting depth feed

MEFC precision machining groove type conventional precision machining working conditions

Chip breaking window: MESI can cover a larger cutting depth ap up to 0.118 inches; MEFF is suitable for extremely low cutting depths; MESL balances sharpness and chip removal.

Recommended Cutting Conditions (Imperial)

Free cutting steel/ordinary carbon steel: Vc=165-660 SFM, feed rate f=0.001-0.004 IPR

Stainless steel: Vc=165-660 SFM, feed rate f=0.002-0.008 IPR. It is recommended to use oil-based wet cooling for processing.

Processing performance test data

All tests are conducted using 316 stainless steel, with oil cooling:

End face turning and outer circle turning: with the same cutting distance, AC1135U has smaller roughness fluctuations; The size change is much smaller than that of ordinary grades and competitor A, and the dimensional tolerance remains stable for a long time.

Cutting processing: 75 pieces of ordinary grade have torn and cannot continue processing; AC1135U can process 125 pieces without tearing, and the tool life is 1.7 times that of traditional grades.

Actual Processing Application Cases

All use MESI groove type, oil cooling:

Dual melting 316 semiconductor equipment parts: continuous turning of outer circle and end face, competitor A processes 20 pieces per blade; AC1135U can produce up to 250 units, increasing its lifespan by 12.5 times.

316 stainless steel parts: continuous outer circular end face, competitor B400 pieces; AC1135U reaches 3060 pieces, with a lifespan of 7.5 times.

304 stainless steel medical equipment parts: low-frequency vibration cutting, AC1135U can process 10000 pieces, while competitor D only has 5000 pieces.

STKN automotive parts: outer chamfer, suppression of export burrs, AC1135U processing of 9500 pieces, competitor E only 6300 pieces, with a lifespan of 1.5 times.

Pure iron automotive parts (intermittent precision machining): resistant to tool tip breakage, AC1135U700 pieces, only 200-500 pieces of competitor F, with a lifespan of 1.4 times.

Typical workpieces: small precision parts such as semiconductor components, medical devices, beverage equipment accessories, automotive sensors/shafts, etc. The material is mainly 304/316 stainless steel, and carbon steel and pure iron can also be processed.
