Sharp KMA-4H-CNC

Q: How much does the Sharp KMA-4H-CNC cost?

The price estimate for the Sharp KMA-4H-CNC is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/sharp-kma-4h-cnc#price; the request is passed to Sharp or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the Sharp KMA-4H-CNC 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

At 29700 lb (13472 kg), the Sharp KMA-4H-CNC weighs far more than any other KMA bed mill; the KMA-3H-CNC below it is listed at 16535 lb (7500 kg). It is the top of the line, a vertical-plus-horizontal spindle machine with 78.7 in (2000 mm) of X travel.

Capacity grows in every direction. Y travel is 47.3 in (1201 mm) and Z travel 39.3 in (1000 mm), the table is 102.3 x 27.5 in (2600 x 700 mm), and it accepts a workpiece of 7000 lb (3175 kg). The spindle nose can stand anywhere from the table surface to 39.3 in above it (0-1000 mm), so tall weldments and stacked fixtures fit under the vertical spindle.

That envelope puts the machine among small boring-mill jobs: pump casings, gearbox housings, press frames. The horizontal NT50 spindle reaches the sides, the vertical one the top, and Sharp says 5-sided operations are possible at one setup with the optional indexer or rotary table. Tools are changed by hand.

Speeds are modest, 45 rpm to 1,500 rpm in 18 steps. Installation is a project in itself: the footprint is 231.5 x 175.2 x 125.2 in (5880 x 4450 x 3180 mm), the supply is 30 kVA and the air requirement is listed as 6-8kg/cm2. Sharp's page does not give a consistent spindle motor rating for this model.

Frequently Asked Questions

01 How big a part can the KMA-4H-CNC take?

The table area is 102.3 x 27.5 in (2600 x 700 mm) and the maximum workpiece weight is 7000 lb (3175 kg). Travels are 78.7 in (2000 mm) in X, 47.3 in (1201 mm) in Y and 39.3 in (1000 mm) in Z, with 0-39.3 in (0-1000 mm) between spindle nose and table.

02 How does the KMA-4H-CNC compare with the KMA-3H-CNC?

The KMA-3H-CNC has travels of 66.93 in (1700 mm), 41.34 in (1050 mm) and 37.4 in (950 mm), a table for 4410 lb (2000 kg) and a weight of 16535 lb (7500 kg). The KMA-4H-CNC has 78.7 in (2000 mm), 47.3 in (1201 mm) and 39.3 in (1000 mm), carries 7000 lb (3175 kg) and weighs 29700 lb (13472 kg). Both need 30 kVA.

03 What control is fitted to the KMA-4H-CNC?

Sharp's feature list names a Fanuc OiMF control with AC servo drives and a 3-axis electronic handwheel (MPG). Positioning accuracy is listed as 0.00039 in (0.01 mm).

04 What should I check before installing a KMA-4H-CNC?

Floor loading for 29700 lb (13472 kg), a space of 231.5 x 175.2 x 125.2 in (5880 x 4450 x 3180 mm), a 30 kVA electrical supply and compressed air at 6-8kg/cm2. The table top is 35.43 in (900 mm) from the floor, which matters for crane loading of 7000 lb parts.
