Small High Precision Drill Presses
Introduction
A drill press is used mainly as a boring tool, but its other useful features make it the most reasonable machine for drilling. A wide range of accessories is available for drill presses, and these accessories increase the utility of the machine. The drill press provides the capability to control the diameter, depth, and angle of the hole during drilling, but you can also use one for sanding, grinding, shaping, and mortising as well.
A small drill press is used for drilling very small holes with high precision. They are used for soft materials such as gold, wood, brass, etc. Some important points to buy a good small drill press are given below.
Keep in mind few things before going to buy small drill press
• Check the concentricity of the drill press according to your requirement.
• Check the grasp capacity of the drill press. If the drill press grasps the material tightly, your work will be easier.
• Smaller chucks give more accuracy. Therefore, try to choose a drill press that has smaller, smooth-acting chucks.
• Check the speed of the motor and spindle. The speed provided by the drill press must be variable. This will help you to work according to the requirement of speed for the material used.
• Choose the drill machine that has smooth working surface. Ideally, the working surface is attached perpendicular to the axis of the drill. Don’t believe the labeled configuration, check the trueness of the table yourself.
• The most important thing is to check the feed of the drill press. If the feed is harsh, it means there is something wrong with the machine, and you will have trouble during your work. The feed must be smooth.
• Machines having a rack and pinion mechanism for the table provide more accuracy and smooth table adjustment.
