How much does the Sharp KMA-1-CNC cost?
Price estimate
We do not have a price for the Sharp KMA-1-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
The Sharp KMA-1-CNC is a CNC bed mill, not a machining center: Sharp states that there is no Automatic Tool Change (ATC). It is the smallest of three vertical-spindle KMA sizes, with 51.2 in (1300 mm) of X travel, 22 in (558 mm) of Y and 21.6 in (548 mm) of Z on the spindle head.
Its character comes from the spindle. A No. 50 taper is driven through an 18-speed gearhead by a 10 hp (7.45 kW) motor, and the speed range is 45 rpm to 1,500 rpm. That is slow by the standards of any tool-changing mill, and it is the point. Large face mills, shell mills and big drills in steel want torque at low speed, and a geared head supplies it. Small cutters in aluminium do not belong here unless the optional 4,600 rpm variable speed head is ordered in place of the 1,500 rpm one.
The frame is a C design on four box ways that Sharp describes as hand scraped, hardened and ground, with a Turcite coating on the slideways. Pneumatic locks on the table and saddle hold the axes that are not feeding during a heavy cut.
The table is long and narrow, 74.8 x 19.7 in (1900 x 500 mm), and carries 3,500 lb (1587 kg). Because the table overhangs the travel, Sharp gives an X/Y cutting range of 51.2/20.8 in (1300/528 mm). The control is a Fanuc OiMF with a 3-axis electronic handwheel.

Frequently Asked Questions
01
No. Sharp's description says there is no Automatic Tool Change (ATC). Tools are changed by hand with the standard power drawbar, and the electro magnetic spindle brake stops the No. 50 taper spindle for the change.
02
Table travel is 51.2 in (1300 mm) in X and 22 in (558 mm) in Y, and the spindle head travels 21.6 in (548 mm) in Z. Sharp also lists an X/Y cutting range of 51.2/20.8 in (1300/528 mm) and a cutting height of 19.6 in (500 mm).
03
The gearhead has 18 speeds from 45 rpm to 1,500 rpm, driven by a 10 hp (7.45 kW) motor. Sharp lists a 4,600 rpm variable speed head in lieu of the 1,500 rpm head as an optional accessory.
04
The KMA-2-CNC has the same 74.8 x 19.7 in (1900 x 500 mm) table and the same 10 hp (7.45 kW) spindle motor, with 59 in (1500 mm) of X, 26 in (660 mm) of Y and 23.6 in (600 mm) of Z travel. The KMA-2-CNC weighs 15,400 lb (6985 kg); the KMA-1-CNC weighs 11,440 lb (5189 kg).
05
Total power consumption is listed as 25 kVA. Floor space is 169.3 x 132 in (4300 x 3353 mm), machine height 117.3 in (2980 mm) and net weight 11,440 lb (5189 kg). The table top is 32.28 in (820 mm) from the floor.
