Parduc M25SC– Professional manual skate sharpening machine

When skate blades demand precision, the quality of the sharpening equipment makes all the difference. The Parduc M25SC is a professional manual skate sharpening machine made in Finland. It is designed for users who value consistent sharpening results, excellent feel and reliable performance.
The M25SC is an excellent choice for ice hockey team equipment managers, professional skate sharpening services, ice rinks and experienced enthusiasts who prefer to maintain control over the sharpening process.
Combining the hands-on control of manual sharpening with an adjustable grinding wheel speed and an exceptionally smooth sliding surface, the Parduc M25SC offers a practical solution for accurate, comfortable and controlled skate maintenance.
 

In addition to adjustable grinding wheel speed, the Parduc M25SC has been further developed with practical use in mind:

• Redesigned upper frame: The diamond dressing position can be adjusted without loosening the cover screws. This makes grinding wheel dressing faster and safer.

• Diamond dressing adjustment nut: Allows the diamond dresser to be moved towards the grinding wheel in a precise and controlled manner, enabling accurate radius profiling in small increments.

• Precision bearing-guided diamond dressing carriage: The carriage movement is precisely guided by bearings integrated into the machine frame. This enables more accurate and repeatable adjustments, resulting in more consistent grinding wheel profiling and reliable skate sharpening results.

Adjustable grinding wheel speed – a key advantage of the M25sc

One of the main differences between the Parduc M25SC and the standard M25 model is its adjustable grinding wheel speed.
As a grinding wheel wears down, its diameter decreases, which also changes its peripheral speed. The M25SC allows the rotational speed to be increased as the wheel wears, helping maintain a suitable peripheral speed even when using a smaller wheel.
This feature supports a more controlled sharpening process throughout the grinding wheel's service life. It makes the M25SC an attractive choice for busy skate sharpening operations where consistent performance and the flexibility to adjust working conditions are important.

Manual sharpening gives you greater control

Not every sharpening task needs to be automated. Manual skate sharpening allows the operator to feel how the blade responds and control the sharpening process through their own technique.
The Parduc M25SC is designed to provide a good feel for the blade while allowing the operator to control sharpening pressure and movement. This is particularly valuable for experienced sharpeners who want to adapt their technique to different skate types and blade requirements.
The machine's stable construction and smoothly moving skate holder support precise operation. With well-maintained equipment and the right technique, the operator can focus on what matters most: careful blade handling and consistent sharpening results.

An exceptionally smooth sliding surface for easier operation

The Parduc M25SC features a ceramic-coated stainless steel sliding surface. The skate holder moves across the surface on felt pads, allowing smooth, effortless movement during sharpening.

The main benefits include:

• Smooth movement: Low resistance makes the skate holder easier to guide and control.
• Excellent feel: The operator can concentrate on blade movement and sharpening pressure.
• Comfortable operation: Smooth movement helps reduce the effort required during repetitive sharpening work.
• Easy maintenance: The sliding surface is also available as a replacement part.

These features are particularly useful for ice hockey clubs, ice rinks and professional sharpening services where large numbers of skates are maintained regularly.

Large grinding wheeland stable construction
 

The construction of a skate sharpening machine plays an important role in both operating comfort and sharpening control. The Parduc M25SC features a large ceramic silicon carbide grinding wheel and a solid sliding surface.
The large grinding wheel supports smooth operation and helps minimise vibration. The wide sliding surface provides ample room for handling larger skates while reducing the risk of the skate holder slipping off the edge.
The machine is designed for versatile skate maintenance and long-term use. Nearly all its components are manufactured in Finland using quality materials.

One machine for multiple skate types
 

The Parduc M25SC is suitable for sharpening a wide range of skates and removable skate blades, including:

• Ice hockey skates: For regular maintenance of both team and recreational skates.
• Figure skates: For sharpening blades used in figure skating.
• Nordic touring skates: Also suitable for handling long blades.
• Replacement blades: For sharpening various interchangeable skate blades.

The height and angle of the skate holder are adjusted to match the blade thickness using three adjustment wheels. The skate is secured in the holder by turning a lever.

This versatility makes the M25SC a practical option for users who maintain different types of skates throughout the season.

Shape the grinding wheel to match your sharpening needs

When used with the Parduc T6 Universal Spinner unit, the M25SC can be used to shape the grinding wheel for different sharpening profiles, including ROH (Radius of Hollow), Flat Bottom and Flat profiles.

The ability to work with different profiles adds flexibility to skate maintenance. The appropriate profile can be selected according to the skater's preferences, skating style and intended use.

Parduc Spinner Cookie 3 – greater flexibility in grinding wheel profiling
 

The versatility of the Parduc M25SC can be expanded with the Parduc Spinner Cookie 3 spinner stand.

Manufactured in Lahti, Finland, this accessory is designed for the Parduc M25 and M25SC skate sharpening machines. It allows you to use up to three different spinners to shape the grinding wheel to the desired sharpening radius or profile. The Spinner Cookie 3 is ideal for sharpeners who want to adapt grinding wheel profiles to different skating disciplines and individual skater requirements. The ability to use multiple spinners makes switching between sharpening profiles more convenient.
Precise alignment for easier adjustment
The Spinner Cookie 3 features three spring-loaded thumb nuts that allow the spinner stand to be aligned parallel to the grinding wheel. A 3 mm alignment plate positioned along the centreline of the spinners helps align the unit with the sharpening machine and skate.
To profile the grinding wheel, lightly touch the rotating wheel with the spinner. Always check the direction of rotation to ensure that the wheel tightens the spinner's mounting screw rather than loosening it. If you want to get more out of your Parduc M25SC and work with a wider range of sharpening profiles, the Spinner Cookie 3 is a practical addition to precise and versatile skate maintenance.

Replaceable diamond head for easier maintenance

The diamond head used to profile the grinding wheel also affects maintenance costs. On the Parduc M25SC, the diamond tip can be replaced separately, so there is no need to replace the entire diamond dresser assembly when the tip wears out. This replaceable design simplifies maintenance and helps control consumable costs over the long term.
