The surface grinding machine uses an abrasive wheel to cut material into flat surfaces. The device, an essential part of the metal processing industry, is widespread but comes in multiple forms, each with its own set of capabilities.
Circular chuck grinders
This grinder has a round magnetic chuck that keeps workpieces. The circular chuck has a work table that oscillates horizontally, allowing the grinding wheel to move across the part of the workpiece being ground. This type of grinder is automatic and only grinds flat surfaces. This machine has limitations and only works with small workpieces.
Electromagnetic grinders
Here, an electromagnetic force holds the workpiece in place while grinding. The power is switched off to release the item. Electromagnetic surface grinders are the same as circular chuck grinders but substitute a magnetic force to hold the workpiece in place. Electromagnetic grinders are more versatile and can work with more complex shapes.
Mid-size horizontal spindle grinders
Use a round electric motor with a double-insulated housing that keeps the workpiece's surface smooth. The machines are practical and budget-friendly options for businesses that need to grind small areas. However, like all circular chuck grinders, they are limited to grinding flat surfaces and are unsuitable for irregular shapes.
Universal cylindrical grinders
A more advanced surface grinder can generally grind flat and irregular surfaces when properly set up. This universal model can also grind inner surfaces and those of shafts and faces. Its inherent flexibility makes it highly suitable for precision work. Still, the grinder may require some additional devices to achieve the desired level of precision on specific types of surfaces.
Plane grinders
Also known as "plano-mill," these machines have a horizontally oriented, long, and broad grinding wheels and tables that slide vertically. The grinding wheels have more excellent capacities but are more massive than most horizontal grinders. These grinders are used in milling operations. However, as the grinding wheels are much bigger, the grinder has moreroom for movement and, thus, has more flexibility.
Horizontal spindle grinders
This machine has orientation and grinding spindles that work like a drill. The spindle points straight out from the surface of the worktable, and material is removed from the part of the workpiece facing the wheel. Other, more complex forms of surface grinders exist, like the vertical horizontal grinders that rotate about a vertical axis.
The specifications of a surface grinder may vary based on the types and models. Here are some common specifications of the surface grinder machines.
A surface grinder machine needs proper maintenance to achieve its surface finishing and accurate grinding. It also prolongs the machine's life and prevents any breakdowns. Here are some routine maintenance tips for a surface grinder:
Surface grinder machines are essential in the industrial manufacturing sector. Based on their capabilities, surface grinders can also be used for non-metals, including ceramics, rubber, and graphite. In this case, the grinders don't have to be metal burrs and can be modified to accommodate other materials that need a flat surfaces quality, such as graphite.
Aside from manufacturing metal parts, surface grinders can also be used in woodworking where wood requires a high degree of flatness. Having a flat surface is essential in ensuring proper joins and even a polished look.
Exporting industries entails knowing the requirements of different industries that need precisely ground metals. Surface grinders usually have a very stable market when exporting because a wide range of industries requires this machine when manufacturing their products. When seeking surface grinders, it is essential to determine what other metals and materials the grinder has been programmed to handle. This will help when deciding whether the machine can be used to fulfil other industries' needs or not.
When looking for surface grinders, it helps to determine the existing market and where the machine can be easily sold without the hassle of searching for clients for whom the machine would be helpful.
A surface grinder has numerous applications in the industrial and manufacturing sectors. The machine is essential when creating metal parts with a high degree of flatness and smoothness. These include tool and dies, automotive parts, spacers, gaskets, microwave components, semiconductor packages, crystal holders, and electrochemical devices. The list of parts needing surface grinders runs deep, and with each of the parts requiring the machine's services being a crucial component of various industries, the need for surface grinders never wanes.
A number of factors influence the surface grinder machine price.
As previously mentioned, the surface grinder prices sold on Cooig.com vary depending on the types. First, shoppers can see that there are big industrial floor-type grinders and small handheld grinders as well. Many small business owners will lean more towards the handheld ones because they are more affordable, and their businesses may not have a budget for heavy industrial use. Buying a cheaper one with a suitable load for a small business makes financial sense.
Home use surface grinders are also more affordable than industrial ones. Most home users won't need a heavy-duty grinding machine every day. A surface grinder machine in the home would probably wait for months at a time between use. It just doesn't make sense for the average home user to have an industrial-grade machine sitting idle.
Product features are also a reason for different prices. Manual surface grinders with fewer features will be priced lower than those with automatic feeding, gas-powered, or high horsepower features. The more complex the technology is, the higher the price will be. Another reason for price differences is the size of the machine. Smaller, more compact grinders will always be cheaper than bigger, heavier ones because of their size and weight. Transportation costs also factor into some prices. Larger machines are more expensive to transport, and some suppliers will pass those costs onto the end-user.
Warranty packages and after-sales support systems also affect prices. Some brands may offer more comprehensive packages, lifting, and installment fees in particular, while others don't, so buyers will have to pay more for that specific assurance. A good rule of thumb here is to look at the long-term costs of a machine versus its purchase price. A more expensive due to its warranty and after-sales support is a better deal in the long run if a business will need to call on the supplier to assist them in installing or repairing the machine.
Q1: What is the working principle of a surface grinder?
A1: The surface grinder uses a grinder head to cut the surface of the workpiece by moving horizontally. The workpiece is clamped on a magnetic chuck platform. After leveling it to the desired height and angle, the grinding wheel then moves back and forth across the workpiece's surface, removing any excess material or imperfections.
Q2: Which manufacturers offer high quality surface grinder machinery?
A2: Some manufacturers who are known for their high quality surface grinder machines are Okamoto, Achilli, and Kent. Achilli and Kent are surface grinders for marble stones while Okamoto is designed for metal work.
Q3: Are used surface grinders worth it?
A3: Surface grinders are essential in eliminating extra costs and improving the production rate. A used surface grinder machine that is still functional can be worth it if it has any advanced applications that can fulfill the company's needs.
Q4: What are some advantages of surface grinders?
A4: Surface grinders are extremely advantageous as they are the only machines capable of producing flat surfaces with a high degree of accuracy. They are easy to operate and have automatic feeding features that allow for faster grinding speed.
