ULTRA-DEX USA
Frequently asked questions
Common questions about ULTRA-DEX USA from 3G Electric.
What is the ULTRA-DEX USA A20S MWLNL4 boring bar used for?
The A20S MWLNL4 is an indexable boring bar for internal turning and boring on CNC lathes and manual machines. It has a 1-1/4 inch shank diameter and a minimum bore diameter of 1.4700 inches. It uses 432-size inserts. The bar is designed to enlarge or finish holes in metal workpieces. It is typically held in a toolholder or turret and adjusted for diameter. The insert can be indexed when the cutting edge wears, reducing downtime. This bar is suitable for general machining and job shop applications where a standard boring bar is required. Verify toolholder compatibility and machine clearance before use.
What do the designations on ULTRA-DEX USA parting and grooving inserts mean?
Designations such as NG-2L W.031, NG-4L W.189, and NG-6R W.375 indicate insert geometry, orientation, and width. The letters and numbers before the W specify the insert shape and size; L or R indicates left-hand or right-hand orientation. The number after W is the width in inches. For example, W.031 is 0.031 inches wide, W.189 is 0.189 inches wide, and W.375 is 0.375 inches wide. These inserts are used for parting off and grooving. The width determines the groove width or cutoff tool width. Select the designation that matches your groove specification and machine setup.
Are ULTRA-DEX USA inserts compatible with other brands' toolholders?
Compatibility depends on the insert size and style. ULTRA-DEX USA inserts are designed to standard dimensional specifications, but they are not guaranteed to fit all toolholders from other manufacturers. The insert must match the toolholder's pocket size, seat, and clamping method. For example, a 432-size insert requires a toolholder designed for 432 inserts. Always cross-reference the insert designation and toolholder model. 3G Electric can provide dimensional data for ULTRA-DEX USA inserts to help you verify fit. If you are unsure, consult the toolholder manufacturer's documentation or request a sample for trial.
What materials can ULTRA-DEX USA parting and grooving inserts cut?
ULTRA-DEX USA parting and grooving inserts are available in carbide grades suitable for common workpiece materials, including steel, stainless steel, and cast iron. The specific grade and coating determine the recommended cutting speed and feed. For example, uncoated grades may be used for aluminum and non-ferrous alloys, while coated grades are typical for steel and stainless. Always refer to the manufacturer's speed and feed recommendations for the exact insert grade and workpiece material. Cutting conditions, machine rigidity, and coolant also affect performance. 3G Electric can provide the manufacturer's technical data upon request.
How do I select the right ULTRA-DEX USA boring bar for my lathe?
Selection depends on the minimum bore diameter, shank diameter, and insert size required for your operation. Measure the smallest hole you need to bore and choose a bar with a minimum bore diameter smaller than that. The shank diameter must fit your toolholder or turret. Insert size should match the available inserts and the cutting forces expected. For example, the A20S MWLNL4 has a 1-1/4 inch shank and 1.4700 inch minimum bore. Consider overhang and rigidity; longer overhangs require larger shanks. 3G Electric can help cross-reference your requirements to available ULTRA-DEX USA models.
