Products

We offer a comprehensive lineup of Cylindrical Grinding Machines spanning conventional, CNC, and fully automatic configurations -- covering everything from single-piece prototyping to high-volume production lines. Whether your workpiece is a crankshaft, a stepped shaft, or a face-and-cylinder composite part, there is a purpose-built machine in our catalog to match it.

What Types of Industrial Grinding Solutions Do We Offer?

Our product portfolio is organized into six core machine families, each engineered for a distinct class of grinding tasks. The table below maps each family to its primary capability and typical application.

Machine Family Control Level Typical Application
Conventional Cylindrical Grinding Machine Manual / Hydraulic Toolroom work, small-batch OD grinding
Conventional Universal Cylindrical Grinding Machine Manual / Hydraulic OD + taper + internal bore in one setup
Conventional Face And Cylindrical Grinding Machine Manual / Hydraulic Shaft shoulders, flanges, combined face/OD
CNC Cylindrical Grinding Machine (MK/MAK Series) Full CNC Precision shafts, hydraulic spools, rollers
CNC Universal / Face And Cylindrical Grinding Machine Full CNC Complex multi-diameter parts, end faces
Centerless Grinding Machine CNC / Semi-auto Pins, rods, tubes -- no center hole needed
CNC Crankshaft Grinding Machine Full CNC (Follow-type) Engine crankshafts, eccentric journals
Compound Grinding Machine CNC Multi-axis OD + ID + face in a single clamping
Automatic Loading And Unloading CNC Grinding Machine Full CNC + Automation Lights-out mass production cells

Our 35,000 m2 manufacturing campus -- including a dedicated machine tool production base and a hydraulic parts production base -- allows us to build, test, and certify every machine category in-house. All products carry ISO 9001-2015 and CE safety certifications.

Conventional, CNC, or Automatic: Which Grinding Level Fits Your Factory?

Control level is the single biggest decision in selecting a grinding machine. Each tier delivers a different balance of flexibility, throughput, and operator skill requirement.

Conventional

Best for Skilled Toolrooms and Low-Volume Work

Hydraulic-servo conventional machines give experienced operators direct tactile feedback and easy mechanical setup. They excel at one-off repairs, prototype runs under 50 pieces, and situations where part geometry changes frequently. Capital cost is lower, and maintenance relies on standard hydraulic skills rather than CNC programming expertise.

  • Conventional Cylindrical Grinding Machine
  • Conventional Universal Cylindrical Grinding Machine
  • Conventional Face And Cylindrical Grinding Machine
CNC

Best for Repeatable Precision at Medium-to-High Volume

CNC machines store grinding programs, execute sub-micron infeed cycles automatically, and produce part-to-part consistency that manual grinding cannot match. Our MK/MAK Series CNC cylindrical grinders achieve roundness tolerances of IT5 or better in production conditions (internal testing data, 2023). High-speed spindle variants push surface finish to Ra 0.2 um or finer without a superfinishing step.

  • CNC Cylindrical Grinding Machine -- MK/MAK Series
  • High Precision CNC Cylindrical Grinding Machine
  • High-Speed CNC Cylindrical Grinding Machine
  • CNC Cylindrical Grinding Machine With Mobile Grinding Wheel Holder
  • Double Wheelhead CNC Cylindrical Grinding Machine
  • CNC Universal Cylindrical Grinding Machine
  • CNC Face And Cylindrical Grinding Machine
  • High Precision CNC Face And Cylindrical Grinding Machine
  • Double Wheelhead CNC Endface Cylindrical Grinding Machine
Automatic

Best for High-Volume Cells and Lights-Out Production

Automatic loading and unloading CNC grinders integrate gantry robots or vibratory bowl feeders directly with the machine control. A single operator can supervise multiple cells simultaneously. Cycle time per part drops because human load/unload time -- typically 15-25 seconds in manual operation (source: IMTS productivity benchmarking report, 2022) -- is eliminated entirely.

How to Find the Right Grinder Based on Your Workpiece Geometry?

Workpiece geometry determines which machine axes and wheel configurations are physically required. Use the guide below as a starting filter before comparing specifications.

01

Plain Cylindrical OD Only

Straight shafts, pins, and rollers with a single OD diameter are the baseline case. Any machine in our conventional or CNC cylindrical lines handles this. For long slender shafts, choose models with steady-rest support and a follow-type grinding cycle.

02

Multi-Step or Tapered Shafts

Parts with shoulder transitions or compound tapers need a swivel table and programmable infeed. Our CNC Universal Cylindrical Grinding Machine and the mobile wheel holder variants make angle changes between diameters simple -- the program stores each position.

03

OD + End Face in One Clamping

Flanged parts, bearing journals with thrust faces, and gearbox shafts with ground shoulders require simultaneous OD and face grinding. Our CNC Face And Cylindrical Grinding Machine series -- including the High Precision and Double Wheelhead variants -- are specifically configured for this geometry. Simultaneous wheel contact eliminates the perpendicularity error that accumulates when you re-clamp.

04

Crankshaft and Eccentric Journals

Crankshaft pin journals are offset from the rotation axis, requiring a follow-type grinding cycle that keeps the wheel centered on the pin as the crank rotates. Our CNC Crankshaft Grinding Machine and Follow Type CNC Crankshaft Grinding Machine are purpose-built for this motion profile. They are used in automotive, marine, and industrial compressor manufacture.

05

OD + ID + Face in a Single Setup

Bearing rings, pump housings, and similar parts require OD, ID, and face grinding without reclamping. Our Compound Grinding Machine addresses this with multiple spindle heads and synchronized CNC axes, cutting total cycle time versus a three-machine routing by up to 40% (internal time-study data, 2023).

06

Centerless Parts (No Center Hole)

Bars, tubes, and small-diameter pins that cannot be fixtured between centers are the domain of the Centerless Grinding Machine. The workpiece rides on a blade between two wheels, making it ideal for high-volume through-feed production of rollers, needle pins, and precision rods.

Which Grinding Machine Matches Your Production Scale and Volume?

Production scale affects not just machine selection but also automation level, floor-space layout, and total cost of ownership. The matrix below aligns volume tiers with recommended configurations.

Annual Volume (parts) Recommended Configuration Key Benefit
Under 500 Conventional Cylindrical or Universal Grinding Machine Low capital, quick mechanical setup, broad versatility
500 -- 10,000 CNC Cylindrical Grinding Machine (MK/MAK Series) Stored programs eliminate re-setup; consistent tolerance
10,000 -- 50,000 High-Speed or Double Wheelhead CNC Grinding Machine Faster cycle times; two-face simultaneous grinding
50,000+ Automatic Loading And Unloading CNC Grinding Machine Near-continuous operation; reduced labor per part
Mixed / Flexible Cell Compound Grinding Machine or CNC Universal with robot Handles multiple part families from one machine footprint

If your production mix changes seasonally or your part family is still evolving, a CNC Universal Cylindrical Grinding Machine with a robot-ready interface gives you the flexibility to add automation later without replacing the core machine.
