How much does the Studer CT960 cost?
Estimated price range
Our best estimate for a cnc grinding machine in this class — not a quote from Studer. Configuration moves it a long way.
Overview
The Studer CT960 is listed here as a 5-axis CNC grinding machine for tools from 1 mm (0.04 in) to 320 mm (12.6 in) in diameter and up to 350 mm (13.8 in) long. Studer's current lineup does not include the CT960, so it is most likely to turn up as a second-hand machine. The listed figures have not been confirmed against a maker's page; use them as a starting point and check each one against the documents of the machine in front of you.
According to the listed figures, five axes interpolate together: X, Y and Z, an A axis that swivels from -10° to +120°, and a C axis with 360° continuous rotation. The grinding spindle is given as 18 kW (24.1 HP) and 10,000 RPM, with wheels up to 250 mm (9.8 in) in diameter and a peripheral speed limit of 80 m/s. The workhead turns at 1 to 2,000 RPM. A span from 1 mm to 320 mm in tool diameter is wide for one machine, so ask which collets, supports and wheel packs come with a particular example, because those decide which end of the range it can cover in practice.
Positioning accuracy is listed as ±0.002 mm on the linear axes and ±2 arcsec on the rotary axes, on a polymer concrete mineral casting base. The control row reads Siemens 840D sl with HELITRONIC TOOL STUDIO software. A workpiece changer holding up to 200 tools appears as an option, so a given machine may or may not have one.

Strengths & Limitations
Strengths
- Five simultaneous CNC axes (X, Y, Z, A, C), with A listed from -10° to +120° and 360° continuous rotation on C
- Listed tool range runs from 1 mm (0.04 in) to 320 mm (12.6 in) in diameter, with lengths up to 350 mm (13.8 in)
- Grinding spindle listed at 18 kW (24.1 HP) and 10,000 RPM, for wheels up to 250 mm (9.8 in) at a peripheral speed of up to 80 m/s
- Listed positioning accuracy of ±0.002 mm on linear axes and ±2 arcsec on rotary axes, on a polymer concrete mineral casting base
Limitations
- Not in Studer's current lineup, and the listed figures have not been confirmed against a maker's page
- The workpiece changer for up to 200 tools is an option, so unattended running depends on how the individual machine was ordered
- Tool length stops at 350 mm (13.8 in) and tool diameter at 320 mm (12.6 in)
- The table gives no axis travels, rapid rates, machine weight or power supply, so installation planning needs the machine's own documents

Frequently Asked Questions
01
No. Studer's current lineup does not include the CT960, which makes it a possible older model that would be bought second-hand. The listed figures on this page have not been checked against a maker's page, so confirm them against the nameplate and manuals of the machine you are considering.
02
Tool diameters from 1 mm (0.04 in) to 320 mm (12.6 in) and tool lengths up to 350 mm (13.8 in). The grinding wheel itself can be up to 250 mm (9.8 in) in diameter.
03
The grinding spindle is listed at 18 kW (24.1 HP) with a maximum speed of 10,000 RPM and a maximum wheel peripheral speed of 80 m/s. The workhead speed range is 1 to 2,000 RPM.
04
The listed figures show 5-axis simultaneous control over X, Y, Z, A and C. The A axis swivels from -10° to +120° and the C axis rotates 360° continuously. Linear travels are not listed, so they have to be taken from the machine's own documentation.
05
Only if the option was ordered. A workpiece changer for up to 200 tools is listed as optional, so check whether the machine you are looking at has it fitted and whether its grippers and pallets are included.
