Arm-Type Drilling Machine Parameters
The parameters of the arm-type drilling machine depend on the intended use. There are three categories of parameters- drilling elements, workpiece-adjustment elements, and adjustable speed. This article outlines the parameters and selection criteria associated with each type.
Drilling Elements
When working with an arm-type drilling machine, some of the elements that have to be taken into consideration include recommended drilling diameter range, maximum spindle speed, maximum drilling feed, and motor power ratings. Each of these parameters helps to determine the best drilling method and the conditions under which it is used.
Additionally, specs like hydraulic pressure, hydraulic fluid capacity, and spindle positions have to be taken into consideration when choosing an arm-type drilling machine. For example, when drilling through complex materials, it is important to adjust the type of hydraulic fluid accordingly. This is because some materials are vulnerable to certain hydraulic fluids. In these cases, a low-pressure, low-capacity hydraulic system can be an ideal option.
Finally, additional elements that are important to consider when using an arm-type drilling machine include the type of drill bit, allowable drilling depth, base rigidity, and vibration dampening characteristics of the arm. These parameters should be kept in mind when selecting a drilling machine for the application.
Workpiece Adjustment Elements
The parameters which impact the positioning of the workpiece are also important factors to consider when purchasing an arm-type drilling machine. The main elements involved include the type of table, allowable range of angular inclination, workpiece centering indexing, and the range of vertical lifting.
The type of table determines the positioning capacity and size needed for the application. Fixed tables have a singular, predetermined positioning capacity, while adjustable tables are able to provide a more flexible range of positioning possibilities. It is important to select the table that best suits the application; this is especially true if the workpiece is of an odd shape, size, or weight.
The next parameter to consider involves the angular inclination. This determines the ability of the arm-type drilling machine to rotate and drill around the workpiece. The allowable range determines the type of applications for which the machine can be used.
The centering indexing parameter is particularly important in repetitive drilling applications. This parameter ensures that the arm is in the correct orientation to precisely drill the holes. The range of vertical lifting determines how independent each axis is from the other. This is especially important for those applications that require added precision in terms of drilling depth.
Adjustable Speed Parameters
The adjustable speed parameters are important when considering the drilling performance of the arm-type machine. The main elements include the range of speeds, the motor type, and the speed regulation adaptability.
The range of speeds determines the applications for which the drilling arm can be used. Whereas low-torque applications require a lower speed range, high-torque applications need a higher speed range. Therefore, the range of speeds should be chosen according to the intended application.
The other adjustable speed parameters include the motor type and the speed regulation adaptability. The motor type and power rating should be chosen according to the application. Depending on the application, direct or bi-directional motors may be needed. The speed regulation adaptability is important because it impacts the speed at which the drill is used. This enables the workpiece to be precisely machined and drilled.
Summary
In summary, arm-type drilling machines are highly versatile and precise machines that can be used for a variety of applications. The parameters that have to be taken into consideration include drilling elements, workpiece-adjustment elements, and adjustable speed parameters. When choosing a drilling machine for an application, it is important to ensure that all the parameters fit the intended use. This helps ensure a successful and precise output.
