As a key component of the drill fixture, the design of the drill bushing is directly related to processing accuracy, efficiency and safety. This blog will detail how to design a custom drill bushing for specific needs, including explaining the importance of custom drill bushings and their impact on drilling efficiency, discussing the materials commonly used for custom drill bushings (e.g., high-speed steel, carbide) and the manufacturing involved Process, discusses factors to consider when designing custom drill bushings, including dimensions, tolerances and compatibility, and highlights the advantages of using custom drill bushings, such as improved performance, reduced wear and cost savings, etc., to help everyone in the process of designing custom drill bushings Don’t feel confused, let’s start learning today!

What Is Drill Bushings?

Drill bushings (also known as jig bushings) are installed in drill fixtures and are used to guide, position and support drill bits, reamers, countersinks and counterbores to ensure accurate and repeatable hole placement during metalworking tasks. Drill bushings prevent cutting tools from deflecting or bending as they enter the workpiece, maximizing chip clearance and minimizing the risk of damaging the workpiece or fixture. Press-fit bushings are permanently pressed into the clamp. Slip-on replaceable bushings can be replaced between jobs, making them ideal for applications where the bushings are expected to wear out before the job is completed. Headless bushings can be fitted tightly together. Headed bushings have an overhang or head that prevents them from being pushed through the clamp, making them ideal for applications where load or vibration may cause the bushing to move. Bushing bushings are installed in a clamp to hold replaceable bushings in place and facilitate replacement of worn or damaged bushings.

Common Drill Bushings Types And Their Characteristics

Drill bushings can be divided into the following types according to their types:

1.Fixed Drill Bushing

The fixed drill bushing is directly pressed into the hole of the drill template or fixture, and an interference fit is used between its outer circle and the hole of the drill template or fixture to ensure that the drill sleeve will not loosen or move during use. It is suitable for a single drilling process in small and medium-sized batch production, especially when the drilling accuracy is required and the production batch is not large.

Features

The structure is simple and easy to install.

The drilling accuracy is high because the position of the drill bushing is fixed and deviation is not easy to occur.

However, it is not easy to replace after wear and tear, and the drill template or fixture needs to be replaced as a whole, which is costly.

2.Replaceable Drill Bushing

The replaceable drill bushing is installed in the bushing, and the bushing is press-fitted on the drill template. The drill bushing and the bushing and the bushing and the drill template are fixed with appropriate matching methods. At the same time, the drill bushing is further compressed by screws and other fasteners to prevent the drill bushing from rotating or withdrawing during the processing.

Features

Easy to replace after wear, simply loosen the fasteners to remove and replace with new drill bushings.

It is suitable for a single drilling process in mass production, which can improve production efficiency and reduce costs.

However, compared with fixed drill bushings, its structure is more complex and requires more operating steps during installation and replacement.

3.Quick Change Drill Bushing

The quick-change drill bushing is designed to meet the needs of drilling, expanding, reaming and other processing methods in sequence in the same process. It can quickly replace drill bushings of different hole diameters without changing the drill template or fixture.

Features

Replacement is quick and easy, just turn the chamfered edge of the drill bushing to the screw and you can easily take it out and replace it with a new one.

It is suitable for occasions that require multiple processing methods in the same process, and can significantly improve production efficiency and flexibility.

The structure is relatively complex, but rapid replacement and efficient processing can be achieved through reasonable design and optimization.

4.Special Drill Bushing

When the workpiece shape or processing conditions limit the use of standard drill bushings, special drill bushings need to be designed. The design of special drill bushings needs to fully consider the convenience of loading and unloading workpieces, the convenience of chip removal and cooling tools, as well as the error prevention device to prevent the workpieces from being installed in the wrong position.

Material Selection For Custom Drill Bushings

High Speed ​​Steel (HSS): This is a common drill bushing material widely used in various drilling operations due to its high hardness and good cutting ability. It is suitable for hand drilling and some equipment with low automation.

Carbide (also called tungsten steel): Compared with high-speed steel, carbide has higher hardness and wear resistance, and is more suitable for equipment with high automation and high precision requirements. Its stability and precision are higher, and it is the first choice material for customized high-precision drill bushings.

Ceramics: Ceramic materials have extremely high hardness and wear resistance, even exceeding that of carbide. Its hardness can be as high as 1600HRC, which is the first choice for processing super-hard materials and customized drill bushings.

Alloy steel: Alloy steel is an iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements to ordinary carbon steel. The properties of alloy steel vary depending on the added elements. Alloy steel has high strength and toughness. High-quality materials for custom-made high-strength drill bushings.

Why do some screws on centrifugal pumps and chemical pumps use hexagon socket screws

As we all know, screws are indispensable fasteners for chemical equipment, and fasteners such as chemical pumps and centrifugal pumps are fixed with screws. There are many ways to fix screws, such as outer hexagon and inner hexagon. Today, we will talk about why hexagon socket screws are used on pumps. The outer edge of the screw head of the hexagon socket screw is circular, and the center is a recessed hexagon. In fact, the advantages of such a structure are obvious. 1. Easy installation. Compared to the outer hexagon screw, the inner hexagon is suitable for more assembly occasions, especially narrow occasions. Therefore, it is very convenient for assembly and maintenance, as well as for debugging. 2. Can be buried in the head. That is, the entire nut is sunk into the interior of the workpiece, which can maintain the flatness and aesthetics of the workpiece surface. 3. More load bearing. It has six force bearing surfaces, making it more capable of being tightened than flat head screws and cross head screws with only two surfaces. 4. Not easy to disassemble. "Our commonly used tools include adjustable end wrenches, screwdrivers, and solid wrenches. However, special wrenches must be used to disassemble hexagon socket bolts. Therefore, it is not easy for ordinary people to disassemble, which is also a benefit.". Note: The materials of hexagon socket bolts are generally made of stainless steel, carbon steel, and alloy steel, and there is basically no difference between the materials of other types of screws. The higher the performance level, the greater the strength. When selecting screws, it is necessary to strictly follow the use requirements to select the appropriate performance level of screws, with different grades and prices The outer hexagon screws are exposed to the outside, and the wrench requires a certain amount of space to tighten them, requiring a large or protruding counterbore. "The inner hexagon requires very small counterbores, and when space is not considered, the inner hexagon is basically a chicken rib.". Therefore, the application of screws depends on the application situation.
