Pinnacle AX170

Q: How much does the Pinnacle AX170 cost?

The price estimate for the Pinnacle AX170 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/pinnacle-ax170#price; the request is passed to Pinnacle or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the Pinnacle AX170 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 Pinnacle AX170 is the smallest AX 5-axis machining center: a Ø170 mm (Ø6.7 in) trunnion table with direct-drive A and C axes under a 15,000 rpm spindle. Linear travels are 360 mm (14.2 in) in X and Y and 440 mm (17.3 in) in Z.

This is a machine for small, intricate parts. The largest workpiece is Ø210 x 180 mm (Ø8.3 x 7.1 in) and the table carries 50 kg (110 lb). Within that envelope the rotary axes are quick: the A axis tilts ±120° at 60 rpm and the C axis turns 360° at 200 rpm, both by DD motor, so there is no worm gear to wear or to add backlash.

The spindle is a direct type rated 5.5 / 9.5 kW (7.4 / 12.7 hp) and 35 / 60 Nm (25.8 / 44.3 lb-ft), S1 and maximum, with a base speed of 1,500 rpm. Pinnacle lists the taper as ISO40 (HSKA63). Linear axes rapid at 36 / 36 / 36 m/min on 25mm roller ways, and oil is circulated through the ball screws to hold thermal growth down.

Stated accuracy is 0.005 mm positioning and 0.003 mm repeatability on X, Y and Z. The accessories list names Heidenhain TNC640, rotary encoders on both rotary axes and a 20-tool arm-type changer. The whole machine weighs 3,800 kg (8,377 lb).

Frequently Asked Questions

01 How big a part fits on the Pinnacle AX170?

The maximum workpiece size is Ø210 x 180 mm (Ø8.3 x 7.1 in) and the maximum table load is 50 kg (110 lb). The table itself is Ø170 mm (Ø6.7 in) with a Ø40 mm (Ø1.6 in) centre hole.

02 How are the rotary axes driven on the AX170?

By DD motors. Pinnacle states that table rotation and tilting are driven by DD motor, with maximum speeds of 60 rpm on the A axis and 200 rpm on the C axis. Rotary positioning accuracy is listed as 5" / 5" and repeatability as 4"/4".

03 What spindle does the AX170 have?

A direct-type spindle with a maximum speed of 15,000 rpm and a base speed of 1,500 rpm. Power is 5.5 / 9.5 kW (7.4 / 12.7 hp) and torque 35 / 60 Nm (25.8 / 44.3 lb-ft), given as S1 and maximum. The taper is listed as ISO40 (HSKA63).

04 What control does the AX170 use?

The accessories list on the page includes Heidenhain TNC640, together with DCM and a kinematics function. A-axis and C-axis rotary encoders are also in that list.
