What Is the Difference between A Deep Hole Drill and A Gun Drill?

Deep hole drill bit is divided into welding deep hole drill bit and machine plus deep hole drill, deep hole drill bit is the use of internal chip, welded deep hole drill bit blade is not interchangeable, one-time use, machine plus deep hole drill blade is interchangeable, machine plus deep hole drill bit knife body can be used permanently, blade can be replaced.

Welded deep-hole drill bitand machine plus deep hole drill bit are using the aniener for coolant, internal chip removal process method, can be in the isocarbon steel, alloy steel solid material drilling deep holes, long-diameter ratio of up to 1:100.

Deep hole gun drill.

1. Belongs to the special deep hole machining tool for extradendritudes. The v-type angle is 120 degrees.

2. Gun drill special machine tool use.

3. Cooling and chip removal are high-pressure oil-cooled systems.

4. There are two types of ordinary carbide and coated head.

Deep hole drilling talk on how to prevent the main failure of the components of CNC machine tools.

1. The fault of the spindle component.

Common failures include: automatic tightening of the tool holder device failure, automatic variable speed device failure, spindle motion accuracy maintenance is unstable.

2. Fault in the feed drive chain.

Its fault swells generally by the decline of sports quality, such as the positioning precision decreased, the reverse gap increased, the workbench in the feed motion of the creeping phenomenon, the bearing noise is too large. This kind of fault is generally by adjusting the pretension force of the motion, adjusting the loose link, adjusting the compensation link and draining the fault.

3. The fault of the automatic tool change rout device (ATC).

The fault of the device is about 50%, manifested in: the movement of the knife library fault, the positioning error is too large, the mechanical grip handle is unstable, the robot movement error is too large, will lead to the change of knife action stuck, the whole machine stopped running.

4. The stroke switch used for position detection is pressed.

The main factors that affect the normal compendcity of the travel switch are the change of the motion characteristics of the moving parts, the reliability of the mechanical device of the compendies and the quality characteristics of the travel switch itself, which is corrected by adjusting or replacing the parts.

5. The fault of the supporting attachment.

The supporting accessories are cutting fluid, chip removal device, rail protection, spindle cooling temperature control box and other faults.

The treatment of mechanical failure is more troublesome, to large-scale demolition and unloading, very much effort, so, maintenance personnel must have more than 90% of the diagnosis of the grasp can ask the mechanics to help, especially in the truth has been cleared, and the experiment on the phenomenon of the necessary analysis, before it can be dismantled. Easily and blindly disassembled.
