What Is a Universal Grinder?

The universal tool grinder has high precision, good rigidity, and is economical and practical. It is especially suitable for sharpening various small and medium-sized tools, such as reamers, taps, twist drills, reaming drills, various milling cutters, milling cutters, and gear cutters. With the corresponding accessories, it can grind the outer circle, inner circle and plane, and can also grind samples and molds. Diamond grinding wheels can be used to sharpen all kinds of carbide tools.

English name: universal tool and cutter grinder ^[1]

To grind all types of tools, the machine is equipped with a range of attachments. The universal tool grinding machine is mainly composed of a bed, a cross slide, a lifting sleeve, a grinding head and various accessories. There are four types of movement: spindle rotation, vertical movement, lateral movement, and vertical lifting movement. Longitudinal movement adopts rolling steel guide; lifting sleeve is driven by rolling screw; lateral movement is sliding guide; grinding head spindle can realize four speeds for grinding different tools. ^[1]

The working table adopts imported high-precision linear rolling guide, the bed is stable, and the operation is lightweight. This machine can be matched with various accessories according to the tool to be ground. It can grind a variety of end mills, end mills, R-type cutters, cylindrical cutters, three-sided edge cutters, single-angle cutters,

Grinding machines and wheels for standard machining

Grinding is widely used and is one of the main methods for precision machining of machine parts. However, due to the high rotation speed of the grinding wheel, the grinding wheel is relatively hard, brittle, and cannot withstand heavy impacts. Accidental improper operation will cause very serious consequences. Therefore, the safety and technical work of grinding processing is particularly important. Reliable safety protection devices must be adopted, and the operation must be focused and ensured. In addition, the fine sand and metal chips splashed on the workpiece of the grinding wheel during the grinding will hurt the workers' eyes. If workers inhale this dust in large quantities, it will be harmful to the body, and appropriate protective measures should also be taken. When grinding, you should pay attention to the following safety technical issues. Before driving, a comprehensive inspection of the machine tool should be carried out carefully, including inspection of operating mechanisms, electrical equipment and magnetic chucks. Lubricate after inspection, test run after lubrication, make sure everything is good before use. Pay attention to the clamping and clamping when mounting the workpiece. The loosening of the workpiece during the grinding process will cause serious consequences such as flying out of the workpiece and hurting the person or breaking the grinding wheel. When starting work, use the manual adjustment method to make the grinding wheel close to the workpiece slowly, and the starting feed amount should be small. Do not use too much force to prevent collision with the grinding wheel. When it is necessary to control the reciprocating movement of the table with the iron stopper, it is necessary to accurately adjust it according to the grinding length of the workpiece and tighten the iron stopper tightly. When replacing the grinding wheel, it must be visually inspected to see if there is any trauma, and then hit with a wooden hammer or stick. It is required that the sound is clear and without cracks. When installing the grinding wheel, it must be assembled in accordance with the prescribed methods and requirements, installed after static balance commissioning, and commissioned. Only after everything is normal, can it be used. Workers should wear protective glasses during work, and balance the wheel to prevent impact. Measuring the workpiece, adjusting or wiping the machine should be performed after the machine is stopped. When using a magnetic chuck, the surface of the disk, the workpiece should be cleaned, tight, and sucked tightly. If necessary, a stopper can be added to prevent the workpiece from shifting or flying out. Attention should be paid to the installation of the grinding wheel protective cover or the machine tool baffle. ^[1]
