The shank part of the shank is mainly used to transmit power. Cobalt collar company can provide 13 categories, a total of 42 specifications of standard tool holders for customers to choose, and can undertake the customization of non-standard tool holders.
Third, the structure of the drill tip part of the geometry of the drill tip part directly affects the cutting performance of the gun drill and the precision of the hole being machined. Cobalt combines its successful experience in manufacturing gun drills for more than 20 years, optimizing the following There are 5 types of drill tip outer circle type, combined with a variety of angles of different angle grinding types for users to choose, to ensure that for different workpiece materials and requirements, there is always a suitable for you.
Type G: General purpose, suitable for processing a variety of materials, especially suitable for processing holes with a small hole tolerance range.
Type C: Standard type, suitable for processing difficult materials such as high alloy steel.
Type E: Special type, suitable for processing various materials, especially suitable for processing holes with large hole tolerance range.
Type A: Special type, suitable for processing various materials under difficult conditions.
Type D: Special type, especially suitable for processing gray cast iron.
Fourth, the use of gun drill gun drill is often made into a single-blade cutter head, it is generally suitable for processing Φ2-Φ20mm diameter small diameter deep hole, length to diameter ratio up to 80 times, gun drill up to 3000mm, the workpiece is processed The surface roughness is Ra0.4-1.6, the aperture accuracy is IT7-9, the linearity of the hole is high, and the orifice is free of burrs, and the repeatability of precision is good. Widely used in the automotive industry, aircraft and shipbuilding industry and machine tool manufacturing industries, the main processing objects are: cylinder block, cylinder head, crankshaft and various engine parts.
Cobalt-neck series gun drills can be used in deep-hole machining special machines, machining centers, turning centers, etc. to meet the requirements of gun drill cooling and guiding, such as carbon steel, stainless steel, cast iron, non-ferrous metals, wood, plastics and other materials, cobalt The company can provide optimal cutting process parameters for the customer's machine condition, ensuring the highest cutting performance of the gun drill. In order to make the gun drill work stably and reliably for a long time, Cobalt also matches the series of gun drills with small and reliable bench-top grinding gun series: TBM116 and TBV116; these two sets of grinding fixtures are compact and occupy an area. Small, easy to use, through a short training, the user can use the fixture to grind the geometric parameters close to the original knife to ensure that the polished gun drill reaches the processing performance and quality of the new knife. The coarse and fine grinding integrated diamond grinding wheel provided by the company: DSS125 can ensure the rough and fine grinding of the gun drill in one clamping, which greatly improves the efficiency and quality of grinding. Supporting tool attachments: drill sleeves, glandes and support seats, etc., to ensure the smooth drilling of the gun drill.
