Cylindrical grinders can be used to achieve precise shaping on any number of manufactured components especially in cases where the internal or external diameter is meant to be perfectly round.
Centerless Technology has over 21 years of experience in precision grinding offering quality grinding services for all of our clients Our dedicated team of experts is prepared to lead your company through even the toughest of grinding challenges.
Manufacturers across industries are turning to cylindrical grinding as a way to save money while still producing high quality high precision components Cylindrical grinding often yields similar or even superior results over other grinding processes such as CNC machining and it does so with quicker turnarounds as well.
These benefits come about largely because of the array of grinding configurations available Different types and combinations of wheel heads and axes can together support a wide variety of uses.
Centerless Technology offers some of the most advanced cylindrical grinding equipment in the industry Our latest acquisition theKELLENBER VARIA UR 1751000 boasts a fully programmable B Axis capable of complex multidiameter grinding as well as internal grinding The machine has a 13 75 swing diameter and measures 40 between centers making it suitable for many tasks that prioritize precision and flexibility.

Centerless grinding is often viewed as overly complex terless grinding theres no flexing be cause the workpiece is supported on three points The workpiece is rotating but not moving its position quot Grindings DECEMBER 2008 VOLUME 60 ISSUE 12 By Alan Richter Editor Centerless grinding is often viewed as overly complex but a look at the.
The usage conditions for wheels can be divided into four categories according to morphology normal shedding loading and glazing Observing the usage conditions of your wheels in order to choose more appropriate wheels is the first step to improving grinding processes.
This phenomenon is caused when the grade of grinding wheel is extremely softened for the grinding condition The grinding wheel cannot be withstood to the grinding force and original grains fall by the destroying of bond Under such the condition as this since the cutting edge intervals of abrasive grains are wide and the workpiece is usually ground by sharp cutting edges though sharpness is extreme the grinding wheel surface becomes rough form is in disorder the precision and finished surface roughness of workpiece become remarkably worse and the grinding wheel is also considerably worn.
This phenomenon is caused when the softened and viscous materials such as aluminum stainless etc are ground Also the phenomenon is easy to cause when chips are adhered to cutting edges built up edge and casting iron stone material etc are ground by dry process Thus chips are caught into pores to clog chip pockets In these two types the grinding force becomes large Especially in the case of former vibration is easy to occur and ldquoPeelingrdquo or ldquoChatterrdquo most especially occurs on the finished surface.
When grade is excessively hard abrasive grain is hard toughness is low and the wheel speed is over for grinding conditions the cutting edges of abrasive grains become dull by proceeding the grinding and the sharpness becomes very worse grinding force is large heat generation mostly occurs and chatter and burn mark also occur much.
When grinding the workpiece is ground by the cutting edges of abrasive grains discharging fine chips The shedding glazing etc of grinding wheel occur from the relationship between this chip shape and each cutting edge of abrasive grain This phenomenon occurs from a constant timing Consequently the grinding mechanism controls condition for that time Chips ground by grinding are fine similarly with chips ground by turning tool and milling cutter The chip is divided into five types as follows.
Ribbon shape chip occurs when grinding wheel sharpness is good.
This chip occur when grinding wheel sharpness is good When brittle materials are ground chips are discharged.
Powder chip occurs when grinding wheel sharpness becomes dull.
Chips are adhered and accumulated on grinding wheel face and these chips are made of texture so as to be the same as built up edge.
These chips are spherical or semi spherical by melting when powder chips are scattered by over heat This is mostly found when ground by loaded or glazed grinding wheel.
