The main types of drill chucks:
Drilling machine fixture is abbreviated as drilling die for machining holes and threads. It is mainly composed of drill sleeve, drill template, positioning and clamping device clamp. The main types are as follows:
(1) Fixed drilling mold: In use, the position of this type of drilling mold is fixed on the machine tool, and the machining precision is high. It is mainly used for processing single hole or radial drilling machine with large diameter on vertical drilling machine. Parallel hole system.
(2) Rotary Drilling Mold: This type of drilling die has an indexing device, so that a plurality of axial or radial hole systems distributed around the axis can be machined on the workpiece.
(3) Flip-type drill: It is mainly used to machine holes on different surfaces of small workpieces. The hole diameter is less than f8~f10mm, which can reduce the number of installations and improve the position accuracy of the holes to be machined. The structure is relatively simple, and the processing die is generally manually turned over, so the fixture and the workpiece should be less than 10 kg.
(4) Cover type drilling mold: This type of drilling mold has no clip specific, and its positioning component and clamping device are directly mounted on the drill template. The drill template is clamped on the workpiece and is suitable for small hole machining on large and bulky workpieces. The fixture and structure are simple and light, and it is easy to remove the chips. However, each time the fixture needs to be loaded and unloaded from the workpiece, it is time consuming, so the quality of the drill is generally not more than 10kg.
(5) Sliding type drilling mold: The sliding type drilling mold is a universal adjustable fixture with lifting drill template. The drilling mold has the advantages of simple structure, convenient operation, quick action and short manufacturing cycle, and is applied in production. wide.
Material characteristic: Using high quality aluminum extruded shutter profiles, multi-layer painting or film layer surface have excellent scratch resistance function, not decay, wearable and anti-collision.Nice white profiles, accepting mass customization according to users requirements(light gray, brown, cream, wood, fused, sand color and light sand color ,etc.)
Integrated protection and decorative features together,the best replacement of traditional theft network security replacement; flexible way open ways, supporting hand control, group control. The door could be your safe rescue channel when in emergency.
When in state of close, support ventilation and lighting, this contribute to enhance the cooling and heating effect of air conditioner, ensure safety, comfortable, energy saving, noise isolation and aesthetics.
