Boring machine technology parameters
Boring machine is an important machine tool in modern machining technology. It is used for processing inner hole, inner taper hole and inner conical hole of various rotating parts. It is widely used in automobile, tractor, bearing and other industries. Boring machines are used to precisely size and shape parts with internal features. With the continuous development of modern industry, boring machines are becoming more and more commonly used. The following is a brief introduction to the characteristics and technical parameters of boring machines:
1. Purpose: Boring machines are used for finishing or semi-finishing of inner holes of workpieces. They are suitable for processing holes with large size, high accuracy and few shape requirements, such as cylindrical holes, inner cone holes and inner taper holes.
2. Classifications: Boring machines can be divided into single-axis boring machines and multi-axis boring machines according to the number of axes. According to the different processing forms and places, boring machines can be divided into vertical boring machines, horizontal boring machines, and gantry boring machines.
3. Structure features: The boring machine tool consists of a column, worktable, workbench, spindle box and a drive system. Column and worktable play the role of supporting and feeding, the spindle box is a place to install the tool and rotate at high speed, and the drive system is used to drive the spindle and the worktable.
4. Working principle: when the workpiece is clamped on the worktable, the spindle box and the worktable drive system can rotate the tool to realize the inner cutting of the workpiece at high speed, and the cutting fluid is used to cool the cutting process and reduce the vibration.
5. Precision: The boring machine can achieve high machining accuracy. The single-axis boring machine can reach IT6-8, and the precision of the multi-axis boring machine can reach IT4-7.
6. Feeding speed: The worktable feeding speed generally does not exceed 5 meters per minute in all cases, and the spindle speed can reach 6000-8000 rpm.
7. Classification of tools: boring tools are divided into round knives and rotary knives according to their shapes. The round knives are all convex blades, which are mostly suitable for processing holes with lower accuracy requirements. The rotary knives are mostly made of hard alloy, which can process holes of higher accuracy and have good heat resistance.
8. Control system: The modern CNC boring machine adopts a computer-controlled system, which can input the numerical control code into the machine tool through the interface. The spindle and worktable can be driven to work accurately and stably according to the code, and the boring machine can realize automatic machining.
In short, the boring machine is a machine tool widely used in modern industry. It has the advantages of high precision, high efficiency, high accuracy and stable cutting performance. With the continuous development of technology, boring machines are playing an increasingly important role in the development of modern industry.
