Guangzhou, Guangdong Mar 3, 2021 (Issuewire.com) - Precision grinding is quite a common CNC machining procedure. The machining factories use grinding machines to cut metal by passing an abrasive cutting surface over the workpiece under pressure. Commonly, grinding machines usually use abrasives in the shape of a wheel, but the disc and belt machines are also sometimes used. Abrasives can cut hardened steels that cannot be cut by other machining methods. Klarm specializes in creating precision machining parts, prototypes, and components. Klarm provides precision grinding China. We would like to introduce our two kinds of grinding machines uses during the tasks like carbon steel grinding, stainless steel grinding, china aluminum grinding, titanium grinding, etc..
One kind of grinding machine is the pedestal grinder and bench grinder, which are used for a wide variety of operations in a machine shop. The only difference between the two is that the bench grinder is somewhat smaller and is mounted on a workbench. The pedestal grinder is larger and has its own base, which is normally bolted to the floor.
Sharpening high-speed steel lathe tool bits and drills are common pedestal and bench grinder tasks. Punches and chisels are also resharpened, and mushrooming can be ground off the striking end of these tools to keep them safe. Worn straight screwdriver tips can be reground to fit screw slots correctly. Heavy deburring can also be performed. Pedestal grinders usually have a water cup mounted in the front for cooling parts as they heat up during grinding. Only ferrous metals should be ground on a pedestal grinder. Grinding non-ferrous metals on a pedestal grinder will clog the grinder wheels, causing them to cut very inefficiently.
Another type of grinder is the tool grinder. It has an adjustable tool rests that can be tilted to various angles. Tool grinders are generally used to sharpen lathe cutting tools. Only ferrous metals or carbide tools should be ground on a tool grinder, depending on the type of wheel installed. Some tool grinders have a coolant system that keeps the tool and wheel cool during grinding.
Here we would like to introduce some more about abrasive belts and grinding wheels. Abrasive belts and discs normally remove material at slower rates than pedestal grinders, so they are often used for lighter deburring tasks. Both ferrous and non-ferrous metals can be ground with abrasive discs and belts. Many varieties of grinding wheels are available for various applications. The characteristics are usually labelled on the side of the wheel on the blotter near the mounting hole. The blotter is a round disc of heavy paper surrounding the center area of a grinding wheel.
It provides a cushion when the wheel is mounted and also provides information about the wheel. Grinding wheel selection for precision grinding can involve many characteristics, but for offhand grinding, the wheel selection is usually based on four main variables: abrasive type, grit (coarseness), wheel size (diameter, hole size, and width), and maximum wheel speed. Here shows a wheel blotter and identifies those four important pieces of information, which are explained in the following paragraphs.
Grinding wheels are constructed with different abrasive types and are selected based on the types of materials they will be used for. The two most common pedestal grinder abrasive types are aluminum oxide and silicon carbide. Aluminum oxide is quite possibly the most common and is used for general-purpose grinding of ferrous metals. Aluminum oxide wheels are gray in color and can be used on pedestal, bench, and tool grinders.
All these kinds of grinding machines ensure the machining manufacturers process at high speed for the precision grinding parts.
