What is a slot machine?
Slotting machines are a type of equipment used to cut metal plates.
There are two types of slotters: angle adjustable and non-adjustable.
The adjustable angle range is between 40° and 135°, and the angle can be adjusted to the desired position within this range.
The main structure of the carver is made of strong and durable steel plate.
The standard machine comes equipped with all necessary tools to meet the processing needs of most sheet metal processing plants.
There is no need to create a separate set of dies, as is common with punch presses, to process parts with a specific angle or thickness.
Angle notching machine has several advantages over punching machines, including:
- Lower cost of use
- Reduced hassle of frequent die changes and fixing with regular punches
- Greater work efficiency
- Decreased work intensity for workers
- Reduced risk for workers
- Quiet processing creates a peaceful working environment for the factory and employees
This slotting machine is ideal for cutting metal plates and is widely used in various industries such as automobile manufacturing, shipbuilding, elevators, electrical equipment, pipes, kitchen appliances and stainless steel products.
Types of slot machine
Slotting machines can be classified into three categories: pedal-operated, pneumatic and hydraulic.
Furthermore, slotting machines can be divided based on the angle of the blades at both ends into adjustable-angle machines and fixed-angle machines.
Hydraulic adjustable angle notchers feature a wide range of cutting angles and remarkable cutting precision. With a cutting angle range typically from 40 to 135 degrees, these machines offer versatility and precision in the cutting process. The angle can be adjusted within this range to obtain optimal cutting results, making it suitable for cutting various materials with different thicknesses. The machine can be adjusted for symmetrical or asymmetrical processing. Furthermore, the cut edge of the plate has a smooth finish.
On the other hand, fixed angle hydraulic notchers have a shear angle of 90 degrees, which provides high cutting speed, compact structure and small volume. These machines are also known for their ease of operation.
Pedal slot machine:
The pedal operating mode, as the name suggests, is operated via the pedal, which not only reduces the work involved but also significantly increases work efficiency. Pedal carver scissors are made of silicone, which provides durability and resists damage and blade collapse.
Pneumatic slotting machine:
This machine mainly uses pneumatic transmission and is designed for cutting square metal boxes and metal disc box corners. The machine is characterized by its relatively lightweight design, attractive, modern appearance and reliable cutting quality.
Hydraulic slotting machine :
This cutting machine is equipped with hydraulic transmission and is a cutting-edge technology designed to quickly and accurately cut triangular notches on the edges and corners of metal plates. It has broad strength and resilience, making it a versatile tool for various hardware processing industries. This type of chamfering machine is widely used and highly sought after in the current market.
