Overview

The INDEX MS52 is a six-spindle CNC automatic for large bar work: bar up to 52 mm (2 in), parts up to 160 mm (6.3 in) long, and main spindles rated 20 kW at 100% / 30 kW at 25% duty with 88 / 130 Nm. Top speed is 5,000 rpm, which fits the diameters it is built for, since a 52 mm bar reaches a given cutting speed at far lower rpm than small stock.

Torque is what sets the MS52 apart. The MS 40E takes 40 mm bar with 24 kW at 7,000 rpm; the MS52 goes to 52 mm (2 in) with 30 kW at 25% duty and 130 Nm, the figures that count for forming, deep drilling and heavy cut-off on large bar.

Back-end work runs on 1 / 2 sub spindles that clamp the full 52 mm (2 in) bar and run to 6,000 rpm. They are rated 5.7 / 7.2 kW at 100% / 40% duty with 18 / 23 Nm, far below the main spindles. The back end is therefore for finishing, drilling and light turning of the cut-off face, and anything heavy has to be done before the part is parted off.

Control is the Siemens S840D sl. The machine weighs 12,000 kg (26,455 lb) and draws 94-127 kW, so floor loading and the electrical supply both need checking before delivery.

Strengths & Limitations

Strengths

52 mm (2 in) bar capacity and parts up to 160 mm (6.3 in) long
Main spindles rated 20 / 30 kW with 88 / 130 Nm at 100% / 25% duty
1 or 2 sub spindles that take the full 52 mm (2 in) bar
Sub spindles reach 6,000 rpm, above the 5,000 rpm of the main spindles, for small back-end tools

Limitations

Main spindles top out at 5,000 rpm, which limits small tools and small diameters
Sub spindles are rated only 5.7 / 7.2 kW and 18 / 23 Nm
12,000 kg (26,455 lb) and a 94-127 kW supply need planning before installation

Best For

Turned parts from bar up to 52 mm (2 in) Parts up to 160 mm (6.3 in) long Heavy forming and drilling that needs up to 130 Nm per spindle Large parts finished on the back end by 1 or 2 sub spindles

Frequently Asked Questions

01 What is the largest part the MS52 can make?

Bar up to 52 mm (2 in) and parts up to 160 mm (6.3 in) long. The sub spindles clamp the same 52 mm (2 in), so a part at full bar diameter can still be taken over for back-end work.

02 How powerful are the MS52 spindles?

Each main spindle is rated 20 kW at 100% and 30 kW at 25% duty, with 88 Nm and 130 Nm of torque on the same basis, and runs to 5,000 rpm. Sustained heavy cuts should be planned on the 100% figures.

03 What does the MS52 offer for back-end machining?

1 / 2 sub spindles running to 6,000 rpm, rated 5.7 kW at 100% / 7.2 kW at 40% duty with 18 / 23 Nm. That is a fraction of the main spindle rating, so plan back-end work as finishing and drilling rather than roughing.

04 How does the MS52 compare with the MS 40E?

The MS 40E takes 40 mm bar, runs to 7,000 rpm and lists 24 kW. The MS52 takes 52 mm (2 in) bar at up to 5,000 rpm with 20 / 30 kW and 88 / 130 Nm. Choose the MS52 when bar size or torque, not speed, limits the part.

05 What installation does the MS52 need?

The machine weighs 12,000 kg (26,455 lb) and its power supply is 94-127 kW. Check floor loading and the incoming supply early, and add the bar loading equipment to the floor plan.
