Drill set of design according to what
When used according to what we to design the jig, the size of the parts, the size of the hole, or the size of the drill with, share below small make up for you:
Drill sets type drill sets installed on the drill template or clamp concrete. Its function is used to determine the workpieces machining hole position, guides the cutting tool for processing, and improve the stiffness of cutting tool in machining process and prevent vibration in machining. According to its structure and usage, can be divided into the following four types.
Drill sets may be substituted: drill set of 1 between cylindrical and bushing with p or harm, bushing 3 2 drill template, etc. Can change drilling apply mechanically fixed screw 4, to prevent the drill bush in the manufacturing process of the rotation and return to drill bit was out of the back. When can change ?
Fixed drill bush: two points A and B type, drill bush is installed in the drill template or clamp concrete, its use or support. And so on. Fixed set of simple structure, drilling position precision is high, it is mainly used for medium and small batch production of the jig.
quick change drill bush: when the workpiece hole needs to be processed in a clamping down in turn during drilling, expanding and reaming processing, successive increase in tool diameter, with the same diameter and hole size with the tool change drill set to boot. It will need a quick change set 'in order to reduce the time to replace the drill sets.
Quick change drill set of cylindrical and bushing cooperate also USES fine or cooperate. The fastening screw convex shoulder than drill set of shoulder slightly higher axial clearance, so you do not need to loosen the screw when take out the drill set, only tao will be a quick change bushing counterclockwise ?
All three of these drill sets have been standardized, the specification can be refer to the relevant national standards.

special drill sets. Due to the particularity of the shape and position of the hole processed, need to design a special drill bush in the form of structure. Welcome to telephone shandong drill set of www.wfzuantao.com
