Gun drilling is the oldest and most widely used method of deep hole drilling employed by industry today. The drill or “gun drill” is generally a one-piece assembly consisting of a hollow cylindrical drill driver. Also, it is brazed to a V-shaped crimped tube and finally assembled to a brazed-on soli

Deep hole drilling is the process frequently used for initial hole generation in large-scale industrial parts. When combined with Drillstar’s industry-leading bore finishing operations, deep hole drilling delivers exemplary levels of precision and efficiency to a wide variety of manufacturing applic

Today, Drillstar will introduce the detection of coolant holes and other characteristics of coolant holes. Firstly, you may notice that the drill bit backlash and cooling holes are not completely aligned. This is because we did not separate the drill bit from the coolant hole.

In the process of mechanical machining, the machining of holes has always been a key and difficult point in the entire machining engineering. Usually, drilling tools such as drills, drill chucks, reamers, honing rods, etc. are used. Floating fixtures are generally not mentioned in the industry, but

Thermal deformation is one of the reasons that affects machining accuracy. Drillstar Machines are affected by changes in workshop environment temperature, electric motor heating, mechanical motion friction heating, cutting heat, and cooling media, resulting in uneven temperature rise in various par
