Turning

Furmanite range of journal turning machine capacities:

• End shaft mounted, 75mm to 1220mm (3” to 48”)
• Mid-shaft mounted, up to 560mm (22”)

Static machining attachments:

• Limitations on what can be machined are not size but access and available mounting places. Each case should be individually assessed

Standard finishes for variable feed turning machines:

• 1.6mm Ra to 6.3mm Ra (63 CLA to 250 CLA)
• Static machining attachments with single point tools, 1.6mm Ra to 6.3mm Ra (63 CLA to 250 CLA)
• Using the Furmanite in house designed orbital grinding and polishing attachments 0.8mm Ra to 1.6mm Ra (32 CLA to 63 CLA)

Tolerances achievable with turning operations:

• For parallel shaft diameters using single point tools, finished tolerances of size + 0.012mm (0.0005”)
• Ground or polished shafts finished tolerances of size + 0.005mm (0.0002”) is dependent on the outside diameter and material of component

Power requirements and utilities required on site:

Journal turning machines

• Air powered machines. Air at 2.7m3/min @ 6 bar, (100 CFM @ 90 PSI)
• Hydraulic powered machines, 415 – 440V 63 Amp 3 phase socket outlet
