Fixed blocks are components in the train industrial sector. Fixed blocks can give the signal community their first failsafe method of detecting the presence of a train. There are moving blocks and fixed blocks in the market and each type has their own characteristics for usages, so neither one is absolutely excellent when users are making their decision but rather, it depends on the working circumstances.
On the other hand, blocks can also be referred to as the blocks of the linear guideways in the machine tool and precision machinery industry, which are the very important parts to realize the smooth movements of the key parts.
Block grinding as one specific kind of grinding methods is studied and developed under serious efforts. There are suppliers who developed block grinding machines , namely the surface grinders, that are designed to grind specifically the sliding blocks as its focused work pieces are the linear guideways.
Block grinding machines are very purpose-oriented grinding machine models that are rarely seen in the market. But for professional users in the automation industry, this type of grinding machines are a must have in their production site. Block grinding machines’ heads would be equipped with grinding wheels as well as dressing tools, so that for the sliding blocks’ exterior side, no matter if it is left or right, block grinding machines are able to process as designed.
Advanced suppliers of block grinding machines often provide some other grinding models that are focused to process stuff such as linear guide rails. Although the block grinding is not totally surface grinding per se, the grinding working mechanism is much like the surface grinding mechanism as the block grinders. People call this type of machines as block grinders for a reason and since sliding blocks are the grinding premises, the blocks’ rectangle shapes rather than cylindrical cones are much similar to flat surface objects.
Not similar to profile grinders, normal block grinders can do much wider jobs, since the grinding heads and dressing wheels can be replaced for the suitable shapes as well as the optimum revolution rates, which is also referred to as the revolution per minutes, abbreviated as RPM.
Professional grinding machines are a rather wide concept in the machine tool inventory within the industrial sectors, because as the near end process of the entire metal working procedure, the grinding of all the surfaces such as cylindrical external and internal, roller surface, center-less grinding, flat surface grinding, profile surface grinding, etc, are all specific models of grinders that are designed based on their own purposes. The research and development of the blocks in the grinding process is thus very important and all those variables in the procedure are to be calculated with professional formula.
There are also few universal grinding machines that can be applied to all the grinding purposes including fixed blocks’ grinding tasks. Most of the grinding machine in the production lines is almost customized products based on the manufacturers’ processing demands. In the sub sector of metal grinding industry, roll grinding and cylindrical grinding are not the same as surface grinding; they have a head that is lowered to a work piece, allowing itself to be moved back and forth under the grinding wheel on a table that generally has a permanent, controllable magnet that acts as a magnetic chuck for use with magnetic stock, but can have a vacuum chuck or other fixture measures for specific purposes.
The generic surface grinding machines contain a grinding wheel that rotates on a horizontal axis cutting amid the grinding wheel circumference. Rotary surface grinding machines, commonly referred to as the Blanchard style grinders, contain a grinding head that rotates the grinding wheel on a vertical axis cutting on the end face of the grinding wheel, while the work piece is rotated toward the opposing direction.
Fixed blocks are grounding using the principle of block grinding. The machinery to which the mechanism applies removes substantial amounts of material and grinds flat surfaces with noted spiral grind marks. It can also be used to produce and sharpen flat shear blades, metal stamping die sets, fixture bases or other flat, parallel surfaces.
