HOW

Marshall
has DEVELOPED SOLUTIONS

“MARSHALL MACHINES LTD, the most innovative machine tool manufacturer in India and the pioneer in ‘Intelligent Automation’ was started as Marshall Industries in 1961 by our visionary founder, Sh. Gautam Sarup. His father had built one of India’s first lathes in 1940 in Lahore and instilled a love for machines in Sh. Gautam Sarup from a very young age. “He was joined by his two sons Gaurav Sarup (in 1986) and Prashant Sarup (in 1989). From Bench Lathes to Capstan Lathes to Multi Spindle Drilling/Tapping machines to CNC Lathes to Intelligent, Automated CNC Cells, it has been a long journey fuelled by a passion for Excellence and Innovation.”

Our design, manufacturing processes & selection of finest machine elements from the best manufacturers in the world ensure the following:

RIGIDITY of Bed & Base
RIGIDITY of Head & Spindle Assembly
RIGIDITY of Tailstock
RIGIDITY of LM Guideways

Our Machine Rigidity is best exempliied by our model RIGIDTURN SL-40-2500 with 650 mm turning Diameter, 2500 mm turning length and 3000 Kg max. job weight. (pls. see attached pictures).
This machine is being used to Hard Turn (O.D.) and soft turn (Ends) of Chilled Rolls with weight of 2500 Kg.
Our design, manufacturing processes & selection of inest machine elements from the best manufacturers in the world ensure the following:
• RIGIDITY of Bed & Base
• RIGIDITY of Head & Spindle Assembly
• RIGIDITY of Tailstock
• RIGIDITY of LM Guideways
This Attribute of RIGIDITY is present in even our smallest models because RIGIDITY is vital for:
