FOR SALE Polar SK EG 4 Mini from 1995 is a precision cutting machine, designed for the processing of paper materials. This specific model has a maximum cutting capacity of 105.49 cm, making it ideal for operations where clean and precise cutting of large sheets is required. This is a high performance guillotine, often used in the printing, bookbinding and packaging industries.
Visually, the Polar SK EG 4 Mini presents itself with a robust and compact structure, typical of machines produced by the Polar brand, characterized by a large cutting area and a resistant work surface. It is constructed of reinforced steel to ensure stability and durability over time. The machine control system is mechanical, with manual adjustments for cutting pressure and material positioning.

Measurements and technical specifications:
Mechanical characteristics: The Polar SK EG 4 Mini uses a mechanical system for the movement of the blade, which can be adjusted to vary the cutting force and speed based on the type of material treated. It is equipped with photocells to ensure safety during the cutting operation, so that the machine stops automatically if it detects the presence of an obstacle.
How to use: Operation is relatively simple: the material is placed on the work table, aligned with the rear guide and blocked. The operator sets the desired cutting size and activates the cutting cycle via a start button. The blade descends quickly and precisely, ensuring a clean cut even on thicker materials.
Matching accessories: The machine can be equipped with optional accessories such as an air blowing system on the work table to facilitate the movement of the sheets, or a lifter to stack the cut sheets.
Formulas for optimal operation: To obtain optimal cuts it is possible to apply formulas that balance the cutting speed and the pressure of the blade according to the thickness and density of the material to be cut. For example, the optimal cutting force (F) can be calculated using the formula: F=(S×T×D)F = (S \times T \times D) Where:
Workable materials: The Polar SK EG 4 Mini is designed to work primarily on paper and cardboard, but can also be used to cut thin plastic materials and some types of film.
Maintenance: Regular maintenance is essential to keep the machine in good condition. It is necessary to lubricate the moving parts, replace the blade when it becomes dull, and periodically check the photocell safety system. An annual check of the electrical circuit is recommended.
Safety regulations: If the machine does not have CE certification, it is important to update it following current regulations. This could include installing safety barriers, adding more modern photocells, and upgrading the emergency stop system.
Evaluation of a good used machine: To evaluate whether a used Polar SK EG 4 Mini machine is in good condition, it is necessary to check the state of the blade, the functioning of the photocells, the fluidity of the blade movements and the integrity of the structure. Furthermore, it is important to examine whether the machine has been maintained regularly and whether the electrical components are in good condition.
Areas of use: The Polar SK EG 4 Mini is widely used in the printing industry, bookbinding, packaging production and in any industry that requires precise cutting of materials on large sheets.
Buying a used Polar machine, such as the SK EG 4 Mini model, is often advantageous because it offers high performance at a lower cost than a new one, with the possibility of finding well-maintained and ready-to-use machines.
