Cylindrical Grinder

Processing Scope

External, internal, taper and step-diameter grinding on shafts, rollers, spindles, bushings and pins, with centerless configurations available for high-volume small-diameter pins and rods fed continuously rather than between centers. Materials include hardened steel, stainless steel and cast iron across the range.

Choosing a Tier

Conventional models suit toolroom and repair work with lower part counts; CNC models suit repeat production where tolerance and cycle-to-cycle consistency matter; centerless models suit high-volume small parts where loading between centers would slow the line down. Most buyers choose based on batch size and part variety rather than diameter alone.

Core Functions

• External, internal and taper grinding on a common cast-iron bed platform
• Handwheel or CNC-programmed infeed depending on the tier selected
• Automatic or manual wheel dressing, matched to the control type
• Optional internal grinding attachment across conventional and CNC models
• Centerless regulating-wheel feed for continuous small-diameter grinding
• Optional in-process gauge on CNC models for closed-loop size control

FAQ

• Q: Should I choose a conventional or CNC cylindrical grinder?
• A: Choose conventional for toolroom, repair or low-volume work where operator skill can control the dial infeed; choose CNC for repeat production where consistent tolerance across a batch matters more than machine cost.

• Q: What is the difference between centerless and between-centers grinding?
• A: Centerless grinding feeds parts continuously between a grinding wheel and a regulating wheel without center holes, which suits high volumes of small-diameter pins or rods; between-centers grinding clamps each part individually and suits larger or more varied parts.

• Q: Can internal grinding be added to an external cylindrical grinder?
• A: Yes, an internal grinding attachment is available on most conventional and CNC models so bore and OD work can be done on the same machine.

• Q: Can I start with a conventional machine and add automation later?
• A: The base mechanical platform is similar across tiers, but moving from conventional to CNC control is normally a new machine order rather than a field upgrade — let us know your growth plan so we can recommend the right starting tier.

• Q: What information do you need to quote the right model?
• A: Part diameter and length range, material and hardness, target tolerance/finish, and expected batch size are enough for us to recommend a tier and configuration.
