GS:TE-LM2_Grinding System: Thread Internal/External – Linear Motor


DRAKE’S GS:TE-LM2 (Grinding System: Thread External/Internal-Linear Motor) Now there’s a larger cousin to the GS:TE-LM linear motor grinder! The Drake GS:T-LM2, is available with a work envelope of 350mm diameter with lengths up to 2 meters. It can be equipped with a power wheel helix (A-axis) and for grinding external (±35° lead angle) and internal threads (±10° lead angle), right or left hand. This new grinder will enable us to serve a wider range of customers – especially those producing larger gears and worms, and longer lead, feed and ball screws.

GS:TE-LM2 Advanced Grinding Features
The GS:TE-LM2 is available with a host of advanced machine design and grinding technologies including:
  • Linear motors on linear ways for maximum acceleration and contouring capability with fewer mechanical parts for low maintenance operation

  • Tenth-micron scale feedback for world class accuracy now and after years of operation

  • Drake Smart Spindle™ technology providing automatic balancing, touch dressing, and part feature locating

  • Drake Smart Form™ technology that automatically generates corrected wheel forms for helical path interference and off helix grinding or calculates setup parameters for generating desired part feature geometry with a standard wheel form

  • Power wheel helix +/- 35° lead angle for external, +/- 10° for internal threads

  • Mineral filled cast polymer base with excellent thermal stability and vibration dampening

  • High static and dynamic stiffness to aggressively grind with the latest super abrasives

  • State of the art Fanuc CNC system for reliability

  • A lean, clean, ergonomic design and compact footprint for operation in a cell environment

The LM2 has been designed from the ground up to take advantage of the latest superabrasives. And, like all Drake grinders, they are delivered pre-programmed for your parts. Drake guarantees good parts out the door from day one.

Power Wheel Helix. +/-35° External Lead Angle,
+/- 10° Internal Lead Angle

Applications
Our LM internal and external thread grinders are well-suited for grinding:

• Taps
• Thread gages
• Multi-start worms
• Electronic steering components
• Fast lead ball screws and nuts
• Feed and bone screws
• Gear box worms
• Transmission parts
• Other high precision components.

And these machines were designed with a compact footprint to easily fit into manufacturing cells.

CNC acoustic touch dressing for generating complex forms

Totally customized programming.
The menu-driven software (you need no programming) is pre-programmed for your exact applications. And you can count on Drake's System Engineers for full-time support and assistance as your needs change and the technology advances.

The total system is pre-tested at our plant on your parts. Then it's proved out for you and prepped for start-up.

The GS:TE-LM2 is delivered with your part programs
already loaded and proved out

You get good parts out the door from day one!

Complex geometries are automatically generated
with consistent precision.
