New DAINICHI DLX152Dx800 | CNC Lathes

Description

This machine is a “hybrid” between manual and CNC control. The machine can be run fully manually with the use of the X, Z and “Guidance” X&Z handles, as well as CNC control.

This unique arrangement allows the operator to perform threading, tapers, contours, radii, chamfers, etc. using the conversational portion of the CNC control, or the manual “Guidance” XZ handle to accomplish the same. No need for compound slides or extra attachments to accomplish everyday tasks.

In addition, RPM and feed rates can be controlled via selector switches mounted on the control panel for fast setting. With the optional NC Statement Editing function, NC programs can be edited and stored.

Graphics on the display aids operator to status of machine functions such as handle rotation direction, cutting direction and tool position. “Guidance Cycle” has Cornering, Grooving, Drilling, Threading and Roughing cycles and Guidance handle synchronization capability for confirming operation or start midway through the program. In total of 20 of cycle and/or taught programs (combined cycles and manual movement) and can be stored.
This control provides a “best of both worlds” scenario for efficient single piece or small lot production.

For over 80 years, Dainichi flat-bed lathes have established a firm position among heavy-duty machining industries worldwide. Over 1,000 units are running in North America since the 1960’s. Featuring high-torque motors and one-piece integrated bed, as well as expanded work areas and large spindle bores, Dainichi lathes are designed to turn larger parts than any other machines in their class.

Machine Features:

Rigid design: One-piece integrated bed is made of solid and high quality meehanite casting which is free from vibration and deformation. Bed slideways are induction hardened and precisely ground (HRC56, 0.1” in depth). X-axis driven by ball screw and tool post with large diameter curvic coupling ensures high thrust force.

Bed: Special care has been given to create a completely symmetrical shape in both the horizontal and vertical directions to reduce distortion and deformation. Effective rib contours and positioning has been added in the direction of torsion, inhibiting vibration when cutting.
• This model features a wide bed width and a deep sliding surface across its entire length with a level degree of hardening.

Headstock: This unique structure design is capable of withstanding heavy cutting. Advanced mechanical engineering has gone into the development of the outer frame, internal partition and rib placement in addition to other areas.
• The main shaft bearing is supported at two points, allowing for a high degree of precision to be achieved with the double row cylindrical roller bearing and the high-speed angular ball bearing set to the front bearing and the double row cylindrical roller bearing set to the rear bearing.
• Spindle speed conversion is handled by an AC (inverter control) motor. A gear system is used to change the range in two stages to obtain a sufficient degree of torque at low speeds.
• Constant surface speed control is a standard feature.

Carriage: The saddle has a broad sliding surface in relation to the bed, and the cross slide and cutter holder have been robustly designed to allow for heavy cutting and maintain a stable level of precision.
• Ball screws are used for the X and Z-axis.

Tailstock: The tailstock and the tailstock spindle provide a sufficient degree of rigidity and are constructed with the main body secured to the base to allow for cross direction slide adjustments.
• A thrust meter comes as standard.
• The base is a rigid structure that is fixed to the bed with clamp plates. Further, a locking device is used to prevent retreating from tailstock thrust.

Lubrication: Grease lubrication is used for the front bearing on the main shaft of the headstock.
• Forced circulating lubrication is used for the gears of the headstock and other bearings.
• Oil bath lubrication is used for the X axis gear box.
• Grease lubrication is used for X axis ball screws.
• A self-lubricating method is applied for the saddle, the sliding surface of the cross slide and the Z axis precision rack and pinion.
