Centerless Grinding Machine
Centerless Grinding Machine :
Description:
A Centerless Grinding Machine is a high-precision machine used to grind cylindrical workpieces without using a center point to hold the part. Instead, it uses two rotary wheels — the grinding wheel and regulating wheel — with the workpiece supported between them. It's ideal for achieving close tolerance, roundness, and smooth surface finish on metal bars, tubes, shafts, pins, and rods.
Where It’s Used:
-
Automobile industry
Bearing industry
-
Medical devices
Tool and die making
-
Steel and metal processing units
Defense sector
-
Electrical motor manufacturing
Uses:
-
Grinding long bars and tubes to precision sizes
-
Achieving perfect roundness and surface finish
-
Removing excess material from workpieces
-
Polishing steel rods, piston pins, and crankshafts
-
Mass production of small cylindrical parts
Importance & Significance:
-
Allows for high-speed and volume production without repositioning
-
Reduces production time and cost in finishing operations
-
Achieves tighter tolerances and superior finishes
-
Ideal for both through-feed and in-feed grinding
-
No need for center holes or chucking fixtures, reducing setup time

FAQs:
-
What is the difference between centerless and cylindrical grinding?
– Centerless grinding does not require the part to be held in a chuck or between centers. -
What type of parts can be processed?
– Bars, rods, bushings, pistons, pins, valves, shafts, and rollers. -
How accurate is centerless grinding?
– Can achieve roundness within 2 microns and surface finish up to Ra 0.1 µm. -
What grinding wheel materials are used?
– Aluminum oxide, CBN, and diamond wheels depending on material. -
Can machines handle different diameters?
– Yes, from 3 mm up to 150 mm diameter, depending on model. -
Is it suitable for small workshops?
– Compact and semi-automatic models are available for small setups. -
Is coolant necessary?
– Yes, to maintain dimensional stability and prolong wheel life. -
Do these machines support automation?
– Yes, many support auto-loading/unloading and CNC interfaces. -
What is the machine price range?
– ?8 Lakh to ?50 Lakh+ depending on size, precision, and automation. -
How often should wheels be dressed?
– Depends on usage; typically after every few hundred parts or when finish drops.
