SUMITOMO PSZ Turn Modular Quick Change Tool System

Core characteristics of the system

Quick change polygon cone positioning structure

Simply loosen one locking screw to replace the entire machining tool head, without the need to remove the entire tool holder from the turret.

X/Y/Z three-axis blade repeat positioning accuracy ≤ 5 μ m; The precision performance in the Y direction (high center of the blade tip) is outstanding, and there is almost no need for compensation after changing the blade.

The rigidity is equivalent to that of an integrated mono block blade, and it will not sacrifice rigidity due to modularity.

Knife shank specifications (metric/imperial square handle)

Metric system: 10 x 10, 12 x 12, 16 x 16, 20 x 20 mm;

Imperial system: 0.375 “, 0.500”, 0.625 “, 0.750”;

The length of the tool holder is 84   mm (10-16 handles) and 100   mm (20 handles); All support internal cooling (- J built-in cooling).

Cooling scheme

The knife holder comes with an internal cooling interface; Support customized integrated cooling blade plate (Gang Plate), plug and play, can switch the cooling pressure (high/low/off) of each tool separately, eliminate exposed hoses, and avoid chip entanglement.

Accessories: Special torque wrench, locking screw (hexagon socket/Torx versions), cooling plug, cooling hose connector; The blade is sold separately.

Auxiliary tool changing fixture: PSZ clamping workstation, offline pre adjustment tool head, external tool alignment, shortening machine downtime.

High temperature alloys: AC5015S, AC5025S

Cast iron: AC4010K, AC4015K

Hard material: CBN BN2000; Nonferrous metals: PCD DA2200, uncoated H1

Key usage points

Torque requirement: The locking screws of different handle numbers have specified torque, and Sumitomo’s dedicated torque wrench must be used. Insufficient torque will result in loss of positioning accuracy, and excessive torque will damage the threads.

The polygonal cone surface must be kept clean, as iron filings can directly damage the 5 μ m repeatability accuracy.

Integrated cutting plate Gang Plate: suitable for the cutting tower of the walking machine, with the tool holder body left on the cutting plate and only the front blade head replaced, greatly reducing tool changing/debugging time; The internal cooling pipeline is integrated inside the blade plate, eliminating the need for external hoses.

The height of the SBT back turning tool holder should have a positive tolerance of+0.1~+0.3   mm to prevent the tool body from interfering with the workpiece.

TGAR blade heads must be matched with Group group numbers and cannot be mixed across groups.

Applicable devices and scenarios

✅  Sliding spindle walking machine, multi axis automatic lathe;

✅  Batch small items: outer circle, end face, contour imitation; Cutting off the outer circular groove; Carrying a car; External thread;

✅  External pre adjustment reduces machine downtime and is suitable for frequent changeover production of multiple varieties;

✅  Internal cooling supports high-pressure cooling, improving the service life of stainless steel and high-temperature alloy cutting tools.
