FAQs of Pratt and Whitney Thread Milling Machine:
Q: How does the Pratt & Whitney TM-200 achieve precise thread milling operations?
A: The TM-200 uses a heavy-duty iron gearbox and a rack and pinion feed mechanism to ensure smooth, accurate movements. An integrated coolant system and automatic lubrication further enhance machining precision, resulting in a consistent surface finish between 0.8 and 3.2 microns.
Q: What types of threads and materials can this machine handle?
A: This thread milling machine accommodates thread pitches from 0.5 mm to 6 mm and lengths ranging from 10 mm to 300 mm. It is suited for industrial use with workpieces up to 150 mm in diameter, and its robust cast iron construction is designed to handle various metals and alloys.
Q: When is it recommended to use this thread milling machine over CNC alternatives?
A: The TM-200 is ideal when manual control, cost-effective operation, and maintenance simplicity are prioritized over automation. Its design gives skilled operators precise control for custom or small-batch jobs where CNC may be unnecessary.
Q: Where should the Pratt & Whitney TM-200 be installed for optimal performance?
A: For best results, install the machine on a properly leveled floor with a three-phase, 415V power supply. Adequate space (minimum 1200 mm x 800 mm) should be provided to accommodate the machines footprint and ensure safe operation.
Q: What is the process for using the manual lever system for control?
A: The operator uses the manual lever controls to set the machining parameters, engage the feed mechanism, and position the workpiece using the 3-jaw chuck. Spindle speed and feed rates are adjustable via belt drive settings and gearbox selection, allowing direct hands-on precision during each thread milling cycle.
Q: How does the integrated coolant and lubrication system benefit operation?
A: The integrated pump delivers coolant continuously to reduce heat buildup and clear machining debris, while the automatic lubrication system ensures critical components are always protected from wearminimizing downtime and extending machine life.
Q: What advantages does this machine offer for exporters, importers, and manufacturers?
A: The TM-200s robust construction, flexibility in handling different thread sizes and materials, and low maintenance requirements make it an attractive choice for businesses involved in heavy industrial applications and international trade. Its manual operation ensures adaptability and reliability across diverse manufacturing scenarios.
