buying a grinding machine
You do not have to hurry to buy industrial machines. According to FactorNeed technical group reviews, buying a surface grinding machine includes steps that must be carefully considered and followed. It is also important to pay attention to the parameters that are effective in determining the price of the machine; Because the purpose of buying is to provide a machine with high quality and efficiency but at a reasonable price. Therefore, the parameters of the machine may not be required for the production line, and by removing them or replacing them with other parameters and facilities, a flat surface grinding machine can be provided at a reasonable price.
Important influential factors in the pricing of surface grinding machine:
The first step in buying is to determine the level of expectations and production goals. If the level of expectation from the machine and the purpose of production are not determined, the probability of error in selecting a machine that can meet the expectations of the production line will be very high. The next step is to pay attention to commercial points and technical points. Business points include purchasing, concluding contracts and reviewing the necessary items in purchasing a brand new machine, including ordering goods, payment, after-sales service, installation and commissioning, which will be done after the completion of technical inspections and approval of the machine.
Technical tips refers to the two parts of the technical tips of the machine and the technical tips of the part or parts under production. Technical tips of the machine include facilities, capabilities and equipment installed on the machine. Which can largely determine the characteristics of the machine whether it can be adapted to the production line or not.
The technical points of the part also include all the information about the part or parts that should be produced. The preparation of industrial maps of parts and the inclusion of all relevant information in it can help in the accurate presentation of the machines offered by the manufacturers. Here are 9 important factors in pricing flat bed grinders:
- Manual or automatic flat grinding machine
- Dimensions of the desk
- Maximum length and width of grinding
- Longitudinal movement size (in manual or automatic mode)
- Dimensions of sanding wheel (grinding wheel)
- Spindle speed (axis) of flat grinding wheel
- Your expected level of flat grinding
- Flat grinding machine brand
- Country of manufacturer of flat grinding machine
25 points to consider when buying a flat surface grinding machine:
After determining the mentioned cases and summarizing the results, you can also use the experiences of FactorNeed technical group in the field of purchasing flat surface grinding machines:
- Industrial maps should be prepared from the desired part or parts and all relevant details and information such as dimensions, weight, material, accuracy and tolerances, etc. should be mentioned in it.
- Communicate your requests and expectations clearly with the manufacturer of flat surface grinding machines.
- Consider the dimensions of the stone wheels and their material, which is determined according to the type of work pieces and the amount of payment.
- Pay attention to the dimensions of the flat surface grinding machine table and its range of motion.
- Specify the speed range of the machine table in rabbit mode and mode while working. Also, specify the amount of load and displacement of the machine in each work cycle.
- Check the height between the table top of the machine and the center of the stone wheel at the maximum distance.
- Examine the load capacity of the table.
- You can specify the type of table holder according to your needs and the type of parts produced. Holders can be used as constraints and fixtures, magnetic table or in the form of three systems.
- Specify the range of motion of the spindle (vertical or horizontal) and its speed in the rabbit position and in the working position.
- Determine the degree of accuracy. This amount can have a direct impact on the accuracy of manufactured parts.
- The power of the spindle motor and its brand and the speed of the stone wheel can be selected in consultation with the manufacturer.
- The power of the hydraulic motor pump (hydraulic and cooling systems) and its brand can also be selected.
- The number of machine axes in CNC surface grinding machines is determined according to the buyer's wishes and the level of expectation from the manufactured parts.
- Make sure that the equipment and safety devices of the machine are complete.
- The convenience of the operator when working with the machine and their programming to be done easily.
- Consider the weight of the machine to prepare the gold for the location of the machine.

- Describe environmental working conditions, including humidity, temperature changes, dust levels, and proximity to other production equipment.
- Write the maximum sound output of pipe bending machines in decibels (DB) (mostly between 50 and 70 decibels).
- If the grinding process is the last process you are considering, ask the manufacturer to prepare the conditions in such a way that it leads to the best result and performance.
- The machine can be powered automatically or by the operator. Describe the type and method of feeding the machine to the manufacturer of the surface grinding machine.
- If the grinding machine uses an automatic control system, specify the brand and model of its numerical control system. For example, you can use LG, Siemens, ABB, Omron, fanuc brands.
- It is better to send the technical information and brand of high-consumption parts, wires, hydraulic pipes, workers, rails, brand and model of motors, bearings, keyboards, etc. to the manufacturer.
- Ask the manufacturer for the electrical circuit diagram of the machine, the list of parts, the connection of the cables, the maintenance manual of the machine and its predicted errors.
- Enter the necessary agreements regarding after-sales services such as transportation, installation, training, replacement and repair warranty, etc. by the manufacturer in writing and have them signed by both parties.
Surface grinding machine
The surface grinding machine is used to polish and adjust the exact dimensions of the flat surfaces of the workpieces. In flat surface grinding, the workpiece is fixed on the workbench (using a magnetic table or using clamps) and the table passes the workpiece from under the stone wheel (in this case It is of circular stone type) with a back and forth movement or a circular movement. Surface grinders are available both manually and automatically; In the manual type, the amount of loading is done by the operator, but in the type of automatic surface grinding, the loading operation and grinding of all surfaces is done by the machine itself.
10 main applications of surface or flat grinding machine:
- In mold making and tool making workshop (especially surface grinding machine with reciprocating table)
- Grinding of flat parts in any size (from small part to steel body of lathe)
- In heavy grinding operations in production lines (especially vertical surface grinding machine with reciprocating table)
- For grinding clutches and gears
- For metal blocks such as car engines
- Railroad tracks
- Suspension spring washers and seats
- Various parts of industrial and non-industrial machines
- Grinding car rims and pistons
- The body of industrial machines and ....
Advantages of flat surface grinding machine:
- Surface grinding can grind a wide range of materials. This advantage makes surface grinding machines more useful than other chipping machines such as mills and lathes.
- Flat stone machine wheels are able to grind parts of different sizes.
- The surface (or flat) grinding machine can grind to an accuracy of 0.0001 inch. Therefore, in addition to polishing flat surfaces, they can grind parts to exact dimensions with high confidence.
- Flat surface grinding machines are used not only for metals but also for other materials, including plastics.
Disadvantages of flat surface grinding machine:
- It requires more time than other chipping machines.
- It has limitations in grinding in such a way that only flat surfaces can be grinded.
- It needs high care because it has a high sensitivity.
Types of flat surface grinding machines
Grinding machines can be divided into 4 types based on the direction of the machine axis and the type of table movement; Which include:
- Types of horizontal surface grinding machine with rotating table
- Types of horizontal surface grinding machine with reciprocating table
- Types of vertical surface grinding machine with rotating table
- Types of vertical surface grinding machine with reciprocating table
The best way to increase the chip removal power of surface grinding machine:
To increase the chip removal power, the spindle (the part on which the stone wheel is mounted) can be slightly angled to reduce friction. In this case, one side of the stone will penetrate more into the piece. It should be noted that due to the reduction in the level of impact of the stone with the workpiece and the pointing of the impact, there is a possibility of hazards such as breakage and throwing particles of the stone wheel around.
