Linear guide way grinding machines are specific grinding machines that can deal with the linear guide ways with the designed capacities as special grinding machines. There are many different types of grinding machines, yet the linear guide way grinding machines are specifically developed to help linear guide manufacturers to deal with their linear guide ways with the top notch functionalities.
Surface grinding machines are the common basis to construct the linear guide way grinding machines, and another fundamental thing is the dial indicator mounted around the tooling system. A dial indicator is a measuring device, which are one of the most primary measuring tools utilized in the precision manufacturing process. For instance, in the engine building, they are typically used to measure deck clearances, crankshaft thrust and straightness. Lifter travel and other measurements that involve the distance between two surfaces or small amounts of component travel are also common in the dial indicator inventory.
Similar to box in box ways’ structure, linear guide ways are a series of direct and straight linear structure that is designed for transmission. Compared to box in box ways, the linear guide ways can make the movements in a much smoother actions with less sudden vibrations during the precision operation, reducing the risks of unstable breaks on the linear guide ways due to the movements of the working surface grinding machines. After the rough grinding, there will be the primary step flatness inspections conducted by the dial indicators.
Instead of manual operation of the dial indicators, the grinding machines based dial indication is much more speedy and convenient during the operation of the linear guide way grinding machines. The overall calibration and inspection of the flatness and the corresponding checked values are sent to the CNC system for further calibration purposes, achieving simultaneous adjustment while grinding.
Another basic but fundamental calibration method is the VERNIER caliper, which is usually utilized to check the width of the linear guides on the linear guide way grinding machines to compensate the horizontal angle flaws. For this part, the works are mainly done by manual operation. VERNIER calipers are often used in precision inspection such as diameter values as the primary means for the accuracy testing due to its fast and precise capacity of the inspection capacity. A VERNIER scale is a small device that is based on visual aid to take an accurate measurement reading of checked values between two graduation markings on a linear scale volume by using mechanical interpolation.
Besides the CNC model, there are also many NC controlled surface grinding machines. It is up to users’ operation demands to choose the matched machine models. In sum, overall speaking, most of the linear guide grinding is conducted on surface grinders. In the subsector of metal grinding industry, cylindrical grinding and roll grinding is not like surface grinding, which has a head that is lowered to a work piece, which is moved backwards and forth under the grinding wheel on a table that typically has a controllable permanent magnet for use with magnetic stock, but can have a vacuum chuck or other fixture tools.
One of the most commonly used surface grinders for linear guides have a grinding wheel rotating on a horizontal axis cutting around the circumference of the grinding wheel. Rotary surface grinders, commonly known as Blanchard style grinders, have a grinding head which rotates the grinding wheel on a vertical axis cutting on the end face of the grinding wheel, while a table rotates the work piece in the opposite direction underneath. This type of machine removes large amounts of material and grinds flat surfaces with noted spiral grind marks. It can also be used to make and sharpen metal stamping die sets, flat shear blades, fixture bases or any flat and parallel surfaces. Surface grinders can be manually operated or have NC control systems.
A rotary surface grinding is a highly effective process due to the massive amount of grinding wheels in contact with the surface part of the work piece materials. Regarding each rotation of the rotary table, the entire surface to be ground comes in contact with the grinding wheel surface. There are many applications that require custom options or electromagnetic, mechanical, vacuum, pneumatic or hydraulic work-holding. Many manufacturing teams specialize in collaboration with their manufacturing or engineering team members to produce work-holding devices in order to meet customers’ manufacturing procedure and achieve great repeatable quality, accuracy and working efficiency, rendering the suitable productivity.
