Maintenance of TSMG 1500/250
Maintenance of Worm/Auger
The worm pin is worn during operation, especially at the place where it drives the knife (knives).
The wear mark is not to exceed 1mm depth, and if this is the case, the worm pin has to be replaced.
Running with a worn worm pin may cause damage of the entire knife hub, which again may result in a total damage of the entire knife set.

Please contact NPK to receive a quote to repair or refurbish your Auger/Worm
It is recommended to purchase an extra worm, which can be used while the other is repaired. NPK offers New, Refurbished, Used and Loaners when available as options.
H nominal = 85 x 85
H maximum = 86.5 x 86.5
The S surface needs to be even and without wear marks
Replacement of the Worm Pin
Please contact NPK to receive a quote to repair or refurbish your Auger/Worm
The worm pin is mounted with LOCKTITE 601 and secured with 2 keys. The keys are welded to the worm, as Shown on the drawing.
1. Grind away the welding.
2. The worm is hung op in the worm pin so that the worm is situated approx. 100 mm above the floor. Place a board between the worm and the floor.
3. Warm up the worm Pin evenly to approx. 2000 C. At this temperature the LOCKTITE will let go and the pin slides out.
4. Let the worm cool of and clean hole and key ways.
5. Mount the new pin with LOCKTITE 601.
6. Weld the keys as shown on the drawing.
7. Grind the weldings even.
Maintenance of Driver Gear
The driver is worn during operation and if A minimum is smaller than stated in the table, the driver is to be replaced.
It is possible to replace the driver yourself (see the spare parts drawing for the gearbox),
Please contact NPK to receive a quote for parts or to replace your Gearbox or Driver.

Maintenance of Knife Housing
The key in the Knife Housing is worn during operation, and from time to time is has to be replaced.
The key prevents the holeplates and precutters from rotating. If it is not whole, this will eventually result in a plate rotating with the knife, which will result in damage of the complete knife set.
Please contact NPK to receive a quote for parts or to replace your Knife Housing. NPK Offers New and Refurbished Options. when available.
Replacement of the Knife Housing Key
Please contact NPK to receive a quote to repair or refurbish your Knife Housing
1. Dismount the Screw.
2. Tap out the Key with a Screw Driver or another blunt object
3. Clean up the Keyway where the Key goes.
4. Insert the new Key.
5. Secure the screw with LOCKTITE 601.
Maintenance of Lining
The lining will be worn during operation depending on which product is being processed. If the internal diameter exceeds the measures as stated below, the lining must be refurbished or replaced.
The larger the working clearance between the lining and worm, the lower the discharge capacity will be. It can also cause smearing of the product
Please contact NPK to receive a quote for parts or to replace your Lining. NPK Offers New and Refurbished Options. when available.

Surface Grinding
Knives, Holeplates and Precutters
NPK provides Surface Grinding, please reach out for quote
To achieve the proper result, the surface grinder chuck must be completely clean and in proper working condition.
Do not use a too high feeding, as this will give unnecessary heat generation, causing oblique parts.
Grinding of Knives and Holeplates
-
Grind one side until it is clean.
-
Turn the part and grind the other side, until it is clean.
-
Turn the part once more and grind the first side once more.
-
The part is now finished.
-
Control the dimensions according to the pictures.
Grinding of Precutters
-
Grind only the side that turns toward the knife.
Control the dimensions in six places for the Holeplate and Precutter and two places on each knife arm as shown. Maximum difference in dimensions: 0.02 mm and thinnest at the center.

The thinner the holeplate is, the more it will tend to bend out because of the pressure, which will give a bad cutting and an increased wear of both holeplate and knife.
The smaller the holes are In the holeplate, the higher the pressure will be.
When using a double knife set, you have to control that the knife hubs do not touch each other, as this will make it impossible to tighten the knife set.
