Estimated price range
Our best estimate for a multi-spindle automatic in this class — not a quote from New Britain Machine. Configuration moves it a long way.
Overview
The New Britain Model 52 is an 8-spindle multi-spindle bar automatic listed for bar up to 52 mm (2 in), with a 4,500 rpm maximum spindle speed and an automatic magazine bar feed. It is not in New Britain Machine's current range and the table has not been confirmed against a maker's page, so everything here is a listed figure for an older machine.
The rows describe the machine in two states, and a buyer has to find out which one is on the floor. The drive type is mechanical cam-operated, the control row reads mechanical cam, cross slide and longitudinal strokes are variable and cam-set, and spindle speed comes in multiple fixed ranges from a cam-selectable gearbox. Alongside those sit retrofit rows: a control system of FANUC 0i-TF or Siemens 828D and a spindle motor of 37–45 kW (50–60 hp), both retrofit-dependent. A cam machine and a converted one are set up, programmed and maintained differently, so settle this first.
Output figures are given for simple work only: a cycle time of 1-5 seconds for simple parts and up to 3,600 parts/hour on simple geometry at maximum rpm. Those belong to short, plain parts; anything with deeper drilling or threading will run slower because the longest station sets the pace. The table lists 8 cross slides and back working, and bar length is 3,000 mm (118 in).
Electrical supply is 460 VAC 3-phase 60 Hz. The weight is listed as 8,500 kg (18,739 lb), which is worth confirming on the data plate before rigging is booked.

Strengths & Limitations
Strengths
- 8 spindles on bar up to 52 mm (2 in), with 8 cross slides listed
- Up to 3,600 parts/hour is listed for simple geometry at maximum rpm, with cycle times of 1-5 seconds for simple parts
- 4,500 rpm maximum spindle speed and a 37–45 kW (50–60 hp) spindle motor, depending on retrofit
- Automatic magazine bar feed with a 3,000 mm (118 in) bar length
Limitations
- The table describes both a mechanical cam machine and a CNC retrofit, so the control and setup method must be confirmed per machine
- Strokes are cam-set and spindle speeds are fixed gearbox ranges on the cam version, which makes changeovers slow for short runs
- The 3,600 parts/hour and 1-5 seconds figures apply to simple parts only
- Bar capacity ends at 52 mm (2 in), and the model is outside the maker's current range

Frequently Asked Questions
01
The listed figures show both. Drive type is mechanical cam-operated and one control row reads mechanical cam, while another lists FANUC 0i-TF or Siemens 828D as retrofit-dependent. Read that as a cam machine that may have been converted, and confirm on the individual machine which state it is in.
02
The table lists a cycle time of 1-5 seconds for simple parts and up to 3,600 parts/hour for simple geometry at maximum rpm. Maximum spindle speed is 4,500 rpm. Parts with longer operations will be slower, since the longest station sets the cycle.
03
Bar up to 52 mm (2 in) in diameter and 3,000 mm (118 in) long, loaded by an automatic magazine bar feed. The machine has 8 spindles, so eight bars are in work at once and bar stock is consumed quickly at the listed output rates.
04
Electrical supply is listed as 460 VAC 3-phase 60 Hz and the spindle motor as 37–45 kW (50–60 hp), depending on retrofit. The listed weight is 8,500 kg (18,739 lb). None of these figures has been confirmed against a maker's page, so check the machine's data plate.
