100 center

Types of 100 centers

A 100 center refers to a machine whose main function is to do dual-insertion drilling, tapping, and milling operations at one setup. The 100 center machine works in various ways, such as CNC (computer numerical control), which is operated and controlled by a computer. Unlike the manual 100 center, the semi-manual/automatic makes use of a hydraulic feed system for drilling. Below are some types of 100 centers.

• Conventional 100 centers: These types of machines use a horizontal spindle with manually operated tables. The methods are mainly used for production work; therefore, the pieces are made out of metal workpieces. Also, light to medium duty metals such as aluminum, copper, brass, and low-carbon steel are beneficial when used with conventional 100 centers.
• CNC 100 centers: These types of machines have more than one spindle, which increases productivity. They are also computer-controlled, which means they have automated operation. In their design, they have a multi-function clamping system that allows various types of processing to be performed on workpieces. This system also enables the use of single or combined toolsets. All these features maximize machining efficiency.
• Semi-automatic 100 centers: Just like the CNC type, the semi-automatic 100 center does not require much effort from the operator, but it still needs some manual setup. The machine has an automatic feed for drilling, while tapping has to be done manually.
• Multi-spindle 100 centers: They are similar to CNC types but operate on different principles. These types are generally used for high-production items. Their main function is to create holes in a workpiece. They have a spindle head that holds multiple taps.
• Radial 100 centers: These types of machines feature a boom (swinging arm) that can pivot and also be adjusted to various angles and heights. The machine has a spindle that can be moved outward or inward along a column. This feature allows easy access to different workpiece locations without the need for repositioning.

Specifications & maintenance of 100 centers

When it comes to the specification of the 100 center, it is crucial to understand its various features.

The heavy 100 center frame includes elements like the headstock, counter shaft, tailstock, and bed, all of which are made of sturdy cast iron. This mechanism strongly resists machine vibrations and shakes from the workpiece during operation, ensuring safety for both the operator and surrounding people.

The universal joint allows the spindle to move up and down, as well as around the horizontal axis on the headstock. The left end of the spindle has various installations through the taper hole, which can center a workpiece or clamp it inside. A belt drive transmits the rotary motion of the workpiece.

The counter shaft connects through the linkage mechanism, which provides a driving force for the transformer to change the spindle speed. This part usually is suspended and connected to the machine bed by belt-driven mechanisms.

The tailstock is positioned opposite the headstock. This component can clamp the workpiece by its threaded clamping or move along the machine bed within a specified range. The clamping thread usually adopts the right-hand thread.

Durableness is another important part that purchasers will care about. Durable 100 centers can have a double-row tapered roller bearing for a tailstock, which helps realize high shapes and durability of machining. Their spindle bass bearings are direct-contact sealing structure designs with constant oil supply, which increase the spindle's rotating system's life span. Moreover, a fan or open-type belts can be used for a drive motor. A double fan open belt drive motor provides noiseless work.

The maintenance of the 100 centers is also important. Regular maintenance ensures its long lifespan and stable performance. Clean the lathe bed and slide rails with a vacuum cleaner every day, and then apply an appropriate amount of lubricant to the slide rails. Cut off the power supply once there is no processing, and be careful not to move the cross slide to avoid damaging the guide rail. Besides, the handle should be relaxed before cleaning.

During operation, ensure the cooling water is flowing and the temperature is constant. Regularly examine the coolant for quality and filtration to avoid overheating. Appropriately adjust the cutting tool and workpiece clamping force to reduce vibration.

The tailstock and tool tray should be adjusted to their suitable position before starting the machine. Avoid moving them to prevent from damaging the guide rails.

Application scenarios of 100 centers

• Public and office buildings

  The 100 center can be used for the effective management of the center air conditioning chillers and heating equipment in various public and office buildings. This way, energy consumption is reduced, indoor spaces are maintained in a comfortable state, and users enjoy a good quality of life.

• Shopping mall

  In the shopping malls, a centralized way is available for the management of air conditioning chillers and heating equipment with the 100 centers. As such, the indoor environment makes for a comforting and pleasant experience for consumers, thus boosting their willingness to shop and spend.

• Hotel

  Hotels can make use of 100 centers to manage the chillers and heating in a centralized manner. As such, guests can enjoy a comfortable accommodation environment. On the other hand, it helps hotels save energy and operating costs, thereby enhancing management efficiency.

• Industrial enterprises

  Industrial enterprises can make use of 100 centers to manage the cooling and heating equipment centralizedly. This way, the production workshops and office buildings maintain a suitable temperature and humidity. Hence, it improves the working environment and boosts employee efficiency.

• Data center

  Data centers can utilize 100 centers for centralized management of cooling equipment. This helps to ensure that the data room remains in a stable and proper temperature and humidity range. Thus, it guarantees the safe operation of equipment such as servers and switches.

• Supermarket

  Supermarkets can make use of 100 centers to manage the central way of heating and cooling. It helps to consistently maintain a comfortable shopping environment. This move also enables the efficient management of energy consumption. This way, it reduces operating costs.

How to choose 100 centers

When choosing 100 centers, consider the following factors to meet specific needs for performance, efficiency, and application suitability.

• Revamping production lines

  When replacing existing machines, select 100 centers with the same workpiece clamping and tooling systems to minimize additional costs for new tools and fixtures. Also, evaluate the condition of other equipment in the line to match the capacity and features of the new machine to existing ones.

• Workpiece mix and production volume

  Take into account the mix of parts produced and their volumes. For low-volume production of many different types of workpieces, prioritize flexibility in setup and clamping over rigidity. Conversely, for large batches of a few workpieces, rigidity and production speed become more important.

• Ease of use and automation

  Consider the level of operator skill and the availability of labor when selecting 100 centers. More operators may be able to run the machine, and less downtime for changeovers will be more important with greater production volume. Look for machines with operator-friendly controls and automated features to lower labor costs per unit.

• Sustainability

  Lowering operating costs is critical to long-term profitability. Look for features that reduce energy use, enhance cooling, decrease tool wear, and shorten cycle times. Better machine design, efficient drives, LED lighting, and other energy-saving aspects can cut electricity expenses significantly. Effective cooling and faster processing reduce tools' consumption and wear, while higher speeds shorten cycles to reduce the cost of each part produced.
