The classification and application fields of handheld belt machine
Hand-held abrasive belt grinding machine for many of the forms and methods, various types of hand-held sander can of large structures, such as parts of aircraft, ships, automobiles, power generation equipment products for grinding and polishing, and can be of many small parts, such as mold, plating, metal pieces, such as polishing, and these parts, especially large pieces of the structure of the grinding is often difficult or even impossible to use other forms of standard belt or wheel grinding machine to solve the. So, hand-held abrasive belt grinding machine is the turbine oil filter oil machine abrasive belt grinding as a part of a complete and independent processing system is indispensable.
(1) portable belt machine
It takes compressed air as power, and the micro pneumatic motor spindle is equipped with a driving wheel, a protective shell and a support, the main supporting frame can be transferred to the structure, and the front end of the contact wheel is arranged. Now portable belt machine electric structure is more common.
Hand-held abrasive belt grinding machine with small volume, light weight, flexible, it is particularly suitable for in mold cavity and complex structure parts, hardware parts, frame corner and weld lines grinding polishing or deburring. The hand-held power belt machine is usually 250~650W.
(2) portable belt machine
It is a hand belt machine is slightly larger than the abrasive belt grinding tool. The power source of the portable belt machine can for compressed air or the power, the maximum power can reach 1.0kw. Therefore, grinding efficiency is high, it is suitable for in a large area of polishing, rust. The grinding contact wheel can press processing need to replace the auxiliary support wheel, polishing polishing arc parts. At the same time, can also be used for various planar surface rust, polishing and grinding welding seam, use range is very wide.
The portable belt machine by the weight limit, the output power are smaller, and the abrasive belt grinding and greater power to fully play the advantage; on the other hand, the grinding power is small also limits the width of abrasive belt, resulting in the short life of the belt. In order to solve this contradiction, the emergence of a power source in the grinding head split models, it with high speed, large power motor as a driving force, and the stepless variable speed, the power into a group or two groups of the special flexible shaft passed to the head, and are interested in design for high speed shaft and the low speed shaft. High speed shaft can be installed on small diameter abrasive such as page wheel, sand ring, low speed shaft is installed more than the size of conventional ashes box portable belt machine belt belt, the product solves the low power general portable belt machine, grinding energy difference and abrasive belt width is narrow, service life short faults.
