1. Start with your workpiece: through-feed or infeed?

A centerless grinding machine usually works in one of two modes, and the WX-M2-60 documentation describes both:

• Through-feed (longitudinal feed) grinding: the workpiece feeds along the axis of the grinding wheel. A small inclination angle on the guide wheel axis drives the axial feed. The documentation describes this mode as suitable for slender cylindrical workpieces and for short shafts, short sleeves and other parts without a center hole.
• Infeed (insert or plunge) grinding: the support plate has an axial positioning fulcrum. The workpiece rests at a fixed position while the grinding wheel or guide wheel feeds in. This mode suits parts with shoulders or heads, and rotating parts such as cones and spheres.

Before you compare suppliers, list your part families and sort each one into a mode. That tells you which of the ranges below apply to you.

2. Check the size envelope against your part range

Some points to keep in mind:

• The 0.8 mm lower limit applies to through-feed only. In infeed mode the smallest listed diameter is 2 mm.
• Infeed length is limited to 125 mm, which matches the 125 mm width of the grinding wheel and guide wheel. Stepped or tapered sections longer than this are outside the published infeed range.
• For long workpieces, the documentation says the machine can be fitted with a through-grinding bracket. Ask whether this bracket is in the standard scope or is an option.

If your parts fall outside these ranges, this model is not the right fit, and you should ask the supplier about other models.

3. Compare accuracy and finish targets on a like-for-like basis

The published accuracy figures come from a standard test bar of ø20 × 75 mm:

• Roundness: 2 μm
• Cylindricity: 3 μm
• Roughness: Ra 0.2 μm
• Grinding feed: 0.002 mm per dial graduation

These are test-bar results. Your parts may differ in material, length-to-diameter ratio and stock removal, so they will not automatically give the same results. If your tolerances are tight, ask for a sample-grinding trial or a written acceptance criterion based on your own drawings.

The documentation also says that a PVA polishing wheel can be fitted in place of the grinding wheel for bright, wet polishing of the workpiece. If you need a polished finish after grinding, ask the supplier how the wheel change and process setup work.

4. Review the machine configuration

The WX-M2-60 documentation lists these design features:

• 125 mm wide grinding wheel and guide wheel. The supplier says the wider wheels give a larger grinding amount and better stability.
• Single-sided movement layout: the regulating wheel frame moves on one side.
• Overhang shafts on both the grinding wheel and the guide wheel, which the documentation says makes wheel replacement easier.
• Frequency-conversion speed control on the regulating wheel (stepless, 5–240 r/min), so you can set the feed speed for workpieces of different diameters.
• Cutting (infeed) mechanism for grinding step surfaces and cone surfaces.

Ask the supplier about the cost and availability of replacement wheels in your market, because wheels are consumables.

5. Confirm utilities and installation fit

Integration problems often come from the site rather than the machine. Check these published values against your workshop:

The power supply is listed as 380 V 50 Hz. If your facility uses a different voltage or frequency, check with the supplier before ordering whether the machine can be adapted or whether you will need a transformer or converter. Also plan floor loading, handling and coolant management around the stated size and weight.

6. Plan for automation from the start

According to the documentation, the automatic version of this centerless grinding machine can work with a range of automatic feeding equipment and automatic manipulators. The documentation also describes centerless grinding as productive and well suited to mass production and automation.

If you plan unattended or high-volume production, ask the manufacturer:

• Which feeding systems or manipulators have been paired with this model, and who supplies them
• How the loading and unloading interface is defined
• Whether automation is quoted as part of the machine or separately

When this machine is not the right choice

The Precision CNC Centerless Grinding Machine 0.8-60mm is probably not suitable if:

• Your workpiece diameters are above 60 mm, or below 0.8 mm (through-feed) or 2 mm (infeed)
• Your infeed sections are longer than 125 mm, or your through-feed parts are longer than 1000 mm
• Your parts need center-type support, or features that do not suit centerless support
• You cannot provide, or adapt to, a three-phase 380 V 50 Hz supply

What to ask any CNC centerless grinding machine manufacturer

The documentation does not cover centerless grinding machine price, delivery time or certification, so request these in writing:

1. A quotation listing the standard scope and any options (brackets, automation, polishing wheel)
2. Lead time and shipping terms for your country
3. Any certifications or compliance documents your market requires
4. Sample-grinding results on your own parts
5. Spare parts, wheel supply and technical support arrangements

Xingtai Xieli Machinery Manufacturing Co., Ltd. makes surface treatment and polishing equipment, and small centerless grinders are part of its range. Share your part drawings, material, tolerance and volume targets so the team can confirm whether the WX-M2-60 fits your application.
