Numerical control precision press

Types of numerical control precision presses

An NC precision press refers to a high-precision mechanical press controlled by numerical control systems. Generally, people divide the types of NC precision presses into two categories based on their working characteristics: the NC precision punch press and the NC precision hydraulic press.

• Numerical control precision punching press: The NC precision punching press is a mechanical punch press with a numerical control system. It uses a high-accuracy spindle to drive the gears transmitting power with the punching force generated through the deformation of the material. The deformation of the material can cut, hole, and other processes for manufacturing products. This kind of press usually is used in the metal forming industry, which can manufacture products or parts with high precision. Moreover, it is known for its high efficiency and automation level.
• Numerical control precision hydraulic press: The NC precision hydraulic press changes the traditional mechanical transmission system by linking hydraulic systems. It uses hydraulic energy to drive the machines henceforth generating a large amount of pressing power. This kind of machine possesses the features of high stability, durability, and strong adaptability as well as operating flexibility. Businesses can use it for various manufacturing processes like stamping, forming, and assembling. Additionally, it can also handle diverse materials and production requirements, making it suitable for use in multiple industries alongside hydraulic force power.

Specifications and Maintenance

• Working Capacity: The working capacity is an important specification of the numerical control precision press machine. It shows the maximum working force that the machine can provide. Usually, this parameter is expressed in tons. For example, if a numerical control precision press has a working capacity of 200 tons, it means it can provide a pressing force of up to 200 tons during work.
• Platen Size: A numerical control precision press has two flat plates known as the upper and lower platens. The two bases hold the material being manufactured. The size of the platens affects the size and shape of the workpieces that can be processed. Larger platens can handle bigger workpieces.
• Working Stroke: The stroke refers to the distance the moving platen travels. It determines the pressing depth of the machine. A greater stroke enables the processing of thicker workpieces. Moreover, press stroke helps determine the time of cycle. An upper press plate moves down to apply force on material between the two plates, which takes time. Then, the upper plate moves up again to finish one cycle. The pressing speed of a numerical control press is usually higher than manual presses. Therefore, the precision machine increases production rate.
• Control System: Numerical control presses utilize a controlling system to direct and regulate the press's actions and parameters. This system typically encompasses an electronic control unit, a human-machine interaction interface, and various sensors and encoders. These components work together to enable precise control over pressing force, velocity, time, and other attributes. Furthermore, the control system may incorporate programmed press modes and preset recipes, allowing for automated and standardized processing procedures. The control system's specifications may encompass factors such as the type and performance of the control unit, the dimensions and resolution of the human-machine interface, as well as the quantity and precision of the attached sensors and encoders.
• Machine Dimensions and Weight: The numerical control press machine's dimensions and weight gives a general idea of its size. The three key machine dimension include length, width and height. Numerical control presses come in different sizes and weights. Their size can be very large. This massive weight means that the machine needs to be securely and steadily installed.

Maintenance

• Cleaning and lubrication: Regularly clean the surface and work area of the numerical control press to remove dust and debris. Additionally, apply lubricating oil to the guide rails, sliding parts, and bearings to ensure smooth operation and reduce friction.
• Inspection and adjustment: Periodically inspect components such as the pressing plate, slider, and guide rails to check for any signs of wear or looseness. Make necessary adjustments or repairs to maintain stability and precision.
• Electrical system maintenance: Inspect the electrical connections and circuits to ensure there are no loose or worn parts. Regularly clean and maintain the control cabinet and electrical components to prevent dust and overheating.
• Safety device inspection: Regularly inspect safety devices such as emergency switches, safety guards, and interlocks to ensure they operate effectively and safely.
• Machine environment maintenance: Keep the surrounding environment of the numerical control press clean and tidy. Ensure proper ventilation and avoid exposure to humid or corrosive places.

  In addition to the specific industry applications mentioned above, CNC precision stamping machines are widely used in various fields of metal parts manufacturing. Whether it is simple or complex, large or small, metal parts can be formed by bending, cutting, reshaping, etc. The precision and quality control of these machines can meet the demands of different industries for metal parts.

How to choose numerical control precision presses

Once buyers know the importance of NCT precision presses in the manufacturing industry, they can easily choose iron presses based on the following factors:

• Production needs analysis

  Manufacturers need to evaluate their production needs before they could pick an NCT precision press. They need to consider factors such as the types of materials to be processed, the desired precision and tolerances, the production volume, and any specific features or capabilities required for their applications. By assessing these production requirements, manufacturers can determine the size, power, and features of the NCT precision press that will best suit their production needs.

• Press types

  Buyers can choose the right NCT precision press for their applications by learning about the various precision press models. This involves considering their functional features, such as the punching, bending, and forming of a variety of materials, as well as their suitability in areas like automobile manufacturing, home appliance manufacturing, and electronic component production. Additionally, the operational environments in which the presses are used, such as workshops and factories, as well as the space constraints, are essential factors to consider.

• Technical specifications

  When choosing an NCT precision press, it's essential to consider its technical specifications. The size and weight of the press should be appropriate for the space and production capacity of the manufacturing facility. Additionally, the power source of the precision press—whether it's electric, hydraulic, or manual—should be considered. Manufacturing facilities must also match the control system of the precision press to their skill level and production needs. Moreover, the materials and manufacturing processes used in the precision press's construction should be of high quality to ensure its stability and reliability.
