Precision and Reliability for Heavy-Duty Turning

The Johnford TC75 is engineered to deliver consistent and precise machining, suited for manufacturers who require reliability in high-volume and heavy-duty operations. Its construction, with a hardened steel and cast iron body, high precision ball screws, and Meehanite cast iron bed, provides exceptional rigidity and reduces vibration for superior surface finishes and extended tool life.

Versatile Control and Automation Options

This CNC lathe supports a choice of industry-standard controllers (Fanuc, Siemens, or Mitsubishi), making it adaptable to various workshop preferences. Automatic centralized lubrication, a programmable tailstock, and an optional bar feeder boost its automation capabilities and ease integration into modern production lines, minimizing downtime and manual intervention.

Advanced Features for Efficient Operation

The TC75 comes equipped with a standard high-pressure coolant system, a robust 30 HP main spindle motor, and rapid traverse rates up to 24 m/min, ensuring swift and efficient machining cycles. Its spacious working envelope delivers a swing over bed of 750 mm and a max turning diameter of 570 mm. These specifications allow the machine to handle a broad range of workpiece sizes.

FAQ's of Johnford Tc75 Cnc Lathe:

Q: How does the Johnford TC75 CNC Lathe ensure machining precision?

A: The TC75 achieves high precision (0.005 mm) through its use of a precision-ground, pre-tensioned ball screw and a high-rigidity Meehanite cast iron bed, coupled with an automatic centralized lubrication system that minimizes mechanical wear.

Q: What are the control options available on this lathe?

A: Operators can select from Fanuc, Siemens, or Mitsubishi CNC controllers depending on their workshop standards, ensuring compatibility with existing production infrastructure.

Q: When should I use the programmable tailstock feature?

A: The programmable tailstock is ideal for supporting long workpieces and minimizing deflection during heavy turning operations, especially when working on shafts or rods with considerable length.

Q: Where is the Johnford TC75 typically used?

A: This CNC lathe is commonly found in machine shops, manufacturing plants, and heavy engineering industries that require robust turning capabilities for medium to large parts, especially in India for exporters, importers, and suppliers.

Q: What is the process for integrating an optional bar feeder?

A: The TC75 is designed for straightforward integration of a bar feeder, allowing automated feeding of raw material for continuous production. Installation and setup should be performed by qualified technicians to ensure seamless operation with the lathe's PLC system.

Q: How does the high-pressure coolant system benefit operations?

A: The standard high-pressure coolant system ensures optimal cutting conditions, extends tool life, and aids in maintaining consistent workpiece quality even during prolonged, high-speed machining cycles.
