SUMITOMO PSZ Turn Quick Change System Selection and Troubleshooting

After changing the tool, it is recommended to use a dial gauge to check the offset of the tool tip in the X, Z, and Y directions. If the repeated accuracy is found to be out of tolerance, priority should be given to checking whether there are foreign objects on the cone surface, whether the cutting head is completely attached, and whether the screws are worn. When the cone surface is pulled or the screw is fatigued, the blade or clamping screw should be replaced. The blade of PSZ Turn can be replaced separately, without the need to replace the entire handle, which reduces maintenance costs.

Common troubleshooting

1. Dimensional deviation or center height change after tool change

Reason: There are chips or oil stains on the cone surface, the blade is not properly attached, the screw torque is insufficient, and the cone surface of the blade is worn. Solution: Clean the cone surface, tighten it to the recommended torque, and recheck it with a dial gauge; If the conical surface is worn, replace the cutting head.

2. Vibration or chatter

Reason: The handle overhang is too long, the center height is inaccurate, the rigidity of the blade head is insufficient, and the blade groove shape is not suitable. Solution: Shorten the overhang and adjust the center height to within ± 0.1mm; It is recommended to have a center height of 0 to+0.2mm during slotting and cutting; choose a sharp slotting type or reduce the feed rate; Check if the connection between the handle and blade is loose.

3. Coolant leakage or insufficient pressure

Reason: The connector is not tightened, the sealing ring is damaged, the hose is aging, and the internal cooling channel is blocked. Solution: Check the Plug&Play connector, replace the sealing ring and hose; Clean the internal cooling channel with compressed air; Confirm that the coolant pressure is within the recommended range. The PSZ Turn handle supports internal cooling and the pressure can be adjusted to low/high/off for different working conditions.

4. Poor chip entanglement or chip removal

Reason: Mismatched chip groove, low feed rate, coolant not aligned with cutting edge, blade wear. Solution: Increase feed rate or cutting depth; Select suitable chip breakers; Adjust the direction of the internal cooling nozzle; Replace the sharp blade. When cutting grooves, the GNDR/GNDL blade combined with internal cooling can significantly improve chip removal.

5. Thread profile exceeding tolerance or disorderly teeth

Reasons: incorrect pitch, improper blade installation, mismatch between feed and spindle speed, and deviation in tool tip height. Solution: Verify the model and pitch of the threaded blade; Reinstall the blade; Check encoder synchronization; Adjust the center height. PSZ ER blade head is compatible with 16ER series blades, pay attention to cleaning the blade positioning surface during installation.

6. The groove width exceeds the tolerance or the groove bottom is rough

Reason: Inconsistent blade width, insufficient rigidity of the cutting head, excessive feed rate, and improper cutting speed. Solution: Choose blades that match the cutting width; Shorten overhang; Reduce feed rate; Increase cutting speed or use internal cooling. TGAR blade covers a cutting width of 0.8-4.8mm, pay attention to the maximum cutting depth limit when selecting.

7. Broken blade or blade damage

Reason: Intermittent impact, insufficient material toughness, excessive parameters, and loose blade installation. Solution: Choose materials with better toughness; Reduce feed and cutting depth; Check blade clamping; Under intermittent working conditions, AC5015S, AC5025S, or BN2000 should be preferred.

Gang Plate and Automated Production Line

The PSZ Turn handle can be installed on the Gang Plate for quick replacement of multiple cutting positions. The advantages of Gang Plate are reduced downtime, quick tool change, no cooling hose entanglement, and the ability to use standard tool holders. The coolant is connected through the Plug&Play interface of the PSZ quick change system, with flexible configuration that allows for individual adjustment of the cooling pressure for each tool position. For automated production lines and unmanned workshops, this modular design reduces manual tool alignment errors and improves tool change consistency.

Recommended cutting parameters and material matching

According to the workpiece material, PSZ Turn blades can be matched with different materials and parameters:

Steel parts: AC530U, AC5015S, AC5025S, cutting speed 160-650 SFM, feed rate 0.001-0.004 IPR.

Stainless steel: AC5015S, AC5025S, cutting speed 160-650 SFM, feed rate 0.001-0.004 IPR.

Cast iron: AC425K, AC4010K, AC4015K, cutting speed 200-1300 SFM, feed rate 0.002-0.008 IPR.

Heat resistant alloys: AC5015S, AC5025S, cutting speed 65-260 SFM, feed rate 0.001-0.003 IPR.

Nonferrous metals: H1, DL1500, cutting speed 650-1000 SFM, feed rate 0.002-0.006 IPR.

High hardness materials: BN2000, DA2200, cutting speed 260-400 SFM, feed rate 0.001-0.003 IPR.

When cutting and slicing, the feed rate is usually 0.001-0.004 IPR, and the cutting depth is limited by the blade and head. When threading, the feed is equal to the pitch, and the cutting speed is selected according to the material.
