How much does the Sharp OD-1320-2X cost?
Price estimate
We do not have a price for the Sharp OD-1320-2X that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Sharp OD-1320-2X is a 2-axis CNC cylindrical grinder for outside diameters, with a 12.6 in (320 mm) swing over the table and 19.7 in between centers. A FANUC Oi-TF control drives the wheelhead infeed and the table, so diameters, shoulders and faces can be ground in one setup, and Sharp adds that tapers and radii can be produced with form dressed wheels or by profiling.
The wheel is a 20 x 2 x 6 in (508 x 50.8 x 152.4 mm) disc turning at 1390 rpm, with a 4 in (101.6 mm) width available as an option for plunge work on wider journals. Its spindle runs in Babbitt bearings, which Sharp describes as a combination of hydrostatic and hydrodynamic bearings carried on a high pressure oil film with no metal to metal contact. The table moves on hydrodynamic slideways. Both choices favour surface finish and damping over rapid motion.
Resolution is where the CNC earns its place. The X axis has a linear scale with 0.00001" resolution, and the smallest programmable infeed is 0.0001 in on diameter. Infeed range is 9 in (228.6 mm). The workhead spindle can be locked or rotated (Fixed & Rotary) at 30-350 rpm and takes an MT #4 center; the tailstock is hydraulic with a 1 in (25.4 mm) stroke.
The wheel drive is listed as 7.5 hp, 10 hp. Sharp's inch and metric figures for the load between centers do not agree, so that capacity is not shown; confirm it for heavy shafts. Net weight is 11,440 lb (5,189 kg).

Strengths & Limitations
Strengths
- X-axis linear scale with 0.00001" resolution is a standard accessory
- Wheelhead on Babbitt hydrostatic and hydrodynamic bearings for vibration damping
- Constant surface speed function for the grinding wheel
- Hydraulic tailstock and infinitely variable workhead (MT4) are standard
- Coolant system with magnetic separator and wheel spindle oil cooler included
Limitations
- Distance between centers is 19.7 in; longer parts need the OD-1524-2X
- OD gauging, the touch probe and gap control are optional devices
- The standard guard is a semi enclosure; the full chip enclosure is an option
- Workhead through hole is only 0.9 in (22.86 mm)

Frequently Asked Questions
01
Swing over the table is 12.6 in (320 mm) and the distance between centers is 19.7 in. Sharp's page gives two different figures for the maximum grinding diameter and two for the load between centers, so neither is shown in the table here; check both with Sharp for work near the limits.
02
A FANUC Oi-TF CNC control with an 8.4" LCD display. Sharp's list of control functions includes circular interpolation (G02, G03), custom macro, coordinate system setting and actual speed display. The grinding wheel has a constant surface speed function.
03
The minimum increment of the wheelhead feed is 0.0001 in on diameter, and the table's minimum incremental feed is also 0.0001 in. The X axis carries a linear scale with 0.00001" resolution. Table rapid feed is 393 ipm.
04
Only with an option. Sharp lists an internal grinding attachment ( 25K RPM) among the optional accessories. Other options include an OD gauging device, a touch probe, a gap control device and a spare wheel flange.
