Sanding Belt Replacement

The technical features of BAND GRINDING MACHINES include some nuances that are characteristic only for this type of power tool. So…

BUTTON FOR LOCKING THE SWITCH FOR CONTINUOUS OPERATION.
This function is on both HOUSEHOLD and PROFESSIONAL LSHM. For the second type, it is more necessary for tireless (relieves stress from the fingers) and long-term work, especially when grinding large areas.

ELECTRONIC TAPE SPEED ADJUSTMENT SYSTEM.
With this option the BAND GRINDER becomes more universal (MAKITA 9911, BLACR & DECKER KA85EK, BOSCH PBS7AE). This LSHM is capable of not only polishing high-quality plastic (at low speed), but also quickly processing a large surface area.
SPEED is set by a special wheel. The same system is found in ELECTRIC DRILLS, BULGARARK, ELECTROLOBZIK.
The most advanced LSM (PROFESSIONAL) have in

its "arsenal" SYSTEM OF SUPPORT OF TURNOVER WITH INCREASING LOAD.
With more pressure on the tool, the SPEED remains the same, respectively, the performance of the LSM remains at the same level.

REMOVABLE AND ADJUSTABLE HANDLE.
REMOVABLE ADDITIONAL HANDLE is quite rare, although there is undoubtedly some benefit from this function. Without the HANDLE, the LSHM becomes a little more compact, which is sometimes an advantage, especially when you need to crawl into an inaccessible place.
The same applies to AN ADJUSTED TILT ANGLE. In this situation, the part is not removed, but tilted back. In addition, if necessary, you can adjust the HANDLE "by the arm" (BLACK & DECKER KA88, XTA80EK).

STATIONARY USE.
TAPE GRINDER, if necessary, can be used as a machine for fine processing of small-sized workpieces. She attaches to

inverted position with the help of special clamps, which, as a rule, are equipped with the majority of LSHM (mainly of the HOUSEHOLD class).
However, with such use of the TAPE GRINDER, extreme caution should be observed, as there is a risk of injury from contact with the fast-moving GRINDING TAPE (SKIL 1205, RUOBI EBS9576V, INTERSKOL LSHM75E).

REPLACING THE SANDING TAPE.
The process of changing the GRINDING TAPE is quite simple: you should press the TAPE TENSION LEVER, then insert a new one in accordance with the signs so that the direction of the arrows on the TAPE and on the housing of the LSM coincides, then return the LEVER to its original position.

AUTOMATIC TAPE CENTERING.
It is believed that this is an invention of SKIL. This option is found in both PROFESSIONAL and HOUSEHOLD models of TAPE GRINDERS (SKIL 7650AA, SKIL 7620AA, BOSCH PSB7A).
It happens that different GRINDING TAPES have different centering: in some it is more accurate, in others. with an error. By manually adjusting the TAPE. using the “lamb”. you have to adjust the position of the front roller. In the process of working with different TAPES, regular adjustment will still be necessary, which takes time and effort (HAMMER LSM800, BORT BBS800, STERN 75X457).
AUTOMATIC setup is easier. One of the rollers has the shape of a barrel (in most LSHMs both are cylindrical), therefore contact with the GRINDING TAPE is incomplete. Therefore, when grinding, even an unbalanced TAPE will not slip to the side.

FRONT ROLLER OF SMALL DIAMETER.
This type of LSM is not common (BLACK & DECKER KA88, BLACK & DECKER XTA80EK). When working close to the wall (grinding the floors), the problem of the “dead zone” arises. an area of ​​the surface inaccessible to the BAND GRINDER from the front edge of the sole to the obstacle itself. It is possible to grind across, but still it is necessary to conduct the LSM along the fibers in order to avoid the appearance of scratches and scoring. An LSHM with a small front roller will cope with the problem. the working surface is increased, and the “dead zones” in the majority are millimeters and are often equal to the radius of the roller.

LIMITATION OF DEPTH OF GRINDING.
Fastens on the case of the BAND GRINDING MACHINE and serves as a peculiar emphasis. It is used for precision work when grinding materials of a large area (furniture and carpentry panels, parquet flooring). The use of the FRAME prevents the appearance of “furrows”. differences in height during operation, as well as with uneven passage through the workpiece (BLACK & DECKER KA85, RUOBI EBS1310F, SKIL 1200).

DUST REMOVAL.
Unlike the ELETROLOBZIK and the CIRCULAR SAW, which “throw out” rather large sawdust, fine dust remains after the operation of the BAND GRINDING MACHINE. You can use a DUST BAG (MAKITA 9910, METABO BAE1075, HITACHI SB8V2), but it will have to be cleaned periodically, especially since only 30-40% of the total amount of “waste” gets into it during operation of the LSM. The use of a DUST BAG or FILTER is, in principle, ineffective, and when stripping metal, it should not be worn at all. if wood dust remains in it, then the risk of fire increases significantly.
Vacuum cleaner solves the problem of dust removal. In the production, special INDUSTRIAL VACUUM CLEANERS are used, and at home, ordinary household vacuum cleaners are also suitable. Some models of BAND GRINDERS are equipped with DUST BAGS WITH ADAPTERS FOR VACUUM CLEANERS (DWT BS650, INTERSKOL LSHM800, SKIL 7650AD). But often they do not fit the hose of a home vacuum cleaner. And in this situation, it’s time to be smart so that you do not have to subsequently clear the airways with various washes and potions.
