Centerless Grinding
Centerless grinding and O.D. grinding are effective methods of surface grinding for round/cylindrical parts to achieve better roundness and ultra-fine OD surface finishes and ultra-tight tolerances parts.
We have decades of experience meeting the stringent regulations and certifications for the automotive, aerospace and medical device industries, which serve as benchmarks for all of the products we manufacture.
Custom-made products
For the purpose of achieving exceptional finishes and tight OD tolerances, centerless grinding is the usual process after CNC Swiss or CNC Turning of precision machined components.
We offer a full complement of grinding services to satisfy the varied needs of products: In-feed grinding, Through-feed grinding and End-feed grinding, Cylindrical grinding, and Honing. For creating the finest surface finish and micro-hardness, the burnishing process is one of the more advanced finishing techniques we use.
Parts produced by this type of machining are commonly found in aerospace, hydraulics, motion control, medical, and high-end electronic industries. Such as shafts, hydraulic valves, thread rods, pins, bushing, fasteners, and similar products.
Fitted for your design and purpose
It is clear that grinding solution is effective, as it allows us to achieve smoother surface polishes, bring out tighter dimensional tolerances, and hold even higher degrees of straightness and roughness in your engineering parts.
KnowledgeAdvantage of Centerless Grinding process
Compared to other machining and manufacturing processes, centerless grinder offers a number of benefits.
No room for deflection
The workpiece is rigidly supported by the regulating wheel, which presses it to the abrasive grains on the grinding wheel. It is well supported under the grinding cut and for the full length of the cut. Thus, there’s no room for deflection to occur in the process. This has also allowed heavier passes other than grinding between centers.
Ability to grind brittle materials and distorted parts
In centerless grinding, there is no axial thrust imposed on the workpiece during grinding which results in the ability to grind different sizes and geometrical figures. It is possible for the centerless grinder to grind long pieces of brittle materials, and even distorted parts, due to the absence of the end pressure.
Short loading time
The short loading time allows for a continuous process compared to grinding between centers. As the name implies, there is no need to support the workpiece in the center. The workpiece goes directly into a “through-grinding” process. The work blade simply holds the workpiece in place and at the correct height, which is critical to achieving the desired diameter tolerance and roundness of the bar material.
Grind large quantities
Centerless grinding can essentially be used in working any size workpiece. Tools like gravity chutes, hopper feeders and magazines are used to adapt the mechanism to different part sizes.
