Grinding steel bars to get the closest tolerance, high precision, and perfect surface finish while cutting away unwanted parts – all under one roof!
Grinding is a critical process that gives final judgment to a steel bar’s tolerance, straightness, and precision. This takes a thoroughly abrasive method of biting and cutting away unwanted bar parts from the material to improve the outer surface.
A wide variety of steel parts, from simple to complex, may require grinding due to a lot of reasons:
- Accurate tolerance needed
- Precise straightness
- Smooth surface finish
- Abrasive material removal
The grinding method has become popular and valuable to most operators since it can bring all necessary work under one roof – with fast lead times. The short material removal accomplishes high-precision work, bringing out the desired physical attributes of a steel bar.
Grinding steel can be done in various ways, depending on the kind of workpiece requiring specific tolerance, cut, and diameter:
Centerless Grinding
This method best fits precision and close tolerance to all machined materials. This popular abrasive grinding process has been first considered in the machining industry. The centreless way can do a raft of machining processes in a single pass, including polishing, boring, turning, and cleaning. Centerless grinding can be done in two different methods such as:
- Thru-feed grinding: The method helps grind long, round bars. The workpiece (bar) goes into the grinding machine, then pulled by the regulating wheel past the grinding wheel, and then flies out on the opposite side. Typically useful for long bars and tubes for automotive and engineering applications.
- Infeed grinding helps smooth steel materials with relatively complex shapes and geometric figures. The workpiece is held stationary in the blade, allowing the abrasive cutting motion to eliminate excess parts. With three-point positioning, the machine can grind even the most minor diameter. Best for parts like camshafts and gear shafts.
OD Grinding
The Outside Diameter (OD) grinding meets exact finish requirements and close tolerance in steel bars. It has four major divisions of techniques, which differ depending on how the workpiece is in the feed direction. OD grinding is ideal for parts with either single or multiple diameters and even for external diameters with cuts or any feature which can cause disruption cut.
ID Grinding
The Inside Diameter (ID) grinding method helps grind several faces and bores in a single operation. The operation is useful for multifunctional cylindrical ID grinding machines to scrape multiple faces and bores to get exact dimensions. This is highly applicable to materials like stainless steel, carbon steel, and aluminum, to be valuable in the automotive, aerospace, chemical processing, and marine industries.
