Device and purpose
Straight grinders have a fairly simple design and are characterized by the absence of complex assemblies. They consist of an electric motor that converts electrical energy into torque, a gearbox that transmits rotation to the working tool of the unit, and a spindle on which various attachments are fixed.The device has a sturdy shockproof housing and is equipped with a comfortable ergonomic grip. A characteristic feature of the tool is its oblong shape and a special elongated structure of the spindle assembly, reminiscent of a long trunk.
The main difference between straight grinders and angular, vibration and broaching samples is the longitudinal position of the spindle relative to the tool axis. Thanks to this design, access to hard-to-reach places is greatly simplified, which cannot be reached with other types of grinders. This allows you to grind the inner surface of narrow holes and clean various parts of complex devices without disassembling them.
The scope of use of FSHM is quite extensive. Thanks to a wide range of accessories with a wide variety of sizes and shapes, the tool is successfully used for removing roughness, unevenness and burrs from wood, metal and concrete surfaces. This allows you to actively use it in auto repair shops to remove rust from units, clean welded seams when performing bodywork and plumbing work, and also use the device in furniture and woodworking industries.
