Landis Type 1R 30° angular
wheelhead plain grinder will:

a grind diameters and faces or shoulders at the same

time

d

grind multidiameter workpieces

■ grind straight or profiled diameters
*

Advantages

b

machine is tooled for high production grinding of

identical workpieces

h

eliminates extra grinding operations

b

saves work handling time

b

live spindle universal type headstock gives machine
capability to

grind work that must be held in a chuck

or special fixture

Performance

:

-
:

■

b

will grind round to less than 25 millionths

b

will hold size to less than 50 millionths

b

will grind to less than 2 micro inch finish

2A

HEADSTOCK-workpieces ground on this headstock
can be round to less than 25 millionths

■ live spindle operation for grinding on centers, or in

a chuck or special fixture

■ spindle bearings have constant and self-adjusting

preload

■ special thermal barrier motor

■ belt driven for smooth rotation and adequate torque

at low speeds

■ start, stop and jog by control lever

FOOTSTOCK—preloaded ball sleeve footstock

improves roundness, straightness and size control

■

Preloaded ball sleeve design eliminates clearance
normally required for sliding fit of footstock spindle.
Never requires take-up for wear

■

Hardened steel spindle is mounted in precision balls

which

are contained in hardened steel bushings.

This is a preloaded interference fit

■ Allows axial movement of spindle with no radial

clearance

plate to eliminate taper

greatly

■ Quick acting lever control for center movement-

work center force is adjustable

HARD FILM MICROSPHERE wheel spindle bear
ings—rounder work, improved finishes, better size

control

■ guaranteed for the life of the machine in the hands

of the original purchaser with normal care and main
tenance

■

high oil film preload resists normal wheel unbalance,

keeps spindle rotating on its geometric axis

■

displacement of the spindle due to grinding load or
wheel unbalance is confined to low millionths

WHEELHEAD—a self-contained unit which includes
spindle, wheelfeed, drive motor, lubricating pump,
isolated oil reservoir and pressure switch

■ machined on all sides for precise mounting of wheel-

head components

■ V and flatways machined integral with the wheelhead





■ dynamically balanced 3 or 5 hp wheel spindle motor

3A

HYDRAULIC INFEED

■ 1" rapid feed, grinding feed and
sparkout

■ turning handwheel indicates rate
and amount of grinding feed

■ grinding feed rate adjustable by

dial control

■ stock removal range, adjustable

to 0.090" on diameter, is auto
matically reset at end of cycle

■

automatic start and stop of head-

stock

■ stock removal feed automatically

resets in conjunction with reset
of rapid feed



i

MICROFEED

■ a mechanical device that ad

vances the wheelhead in incre
ments of 50 millionths after
sparkout

■ Microfeed advances the wheel-

head until finish size is indicated
on an in-process gage applied to
the workpiece during the grind
ing

operation

■ Microfeed automatically compen

sates for all grinding variables

that affect
ness of the workpiece

size, finish and round

LATERAL LOCATOR

■ used for single purpose grinding
when the table needs to be trav

ersed slightly to properly posi
tion the workpiece for plunge
grinding faces and diameters

■ bed mounted with 0.0001" indi
cator

for accurate manual posi

tioning

TRUFORM DRESSER

■

exactly duplicates the form of
the profile bar on the grinding
wheel

■

mounted back of the grinding

wheel

■

dressing is automatically initi

ated after a preselected number
of workpieces have been ground

JT

■ automatic compensating feed
advances wheelhead to compen
sate for reduction in wheel diam
eter

from dressing

■

coolant is supplied through the

diamond bar to the diamond

■ preloaded ball slide eliminates
shake

Other 1R Features That Assure

Higher Productivity, Less Downtime

Operator controls are located front and center for

easiest operation

Eye level wheelfeed permits easy

reduces errors

Swivel table and carriage. For accurate response to

swivel adjustments, swivel stud is mounted in tapered
antifriction bearings adjusted to zero clearance

Landis No-Float carriage lubrication for greater carriage

stability

No oil cups or grease fittings on the 1R grinders—

lubrication and maintenance time is practically eliminated

operation, saves time,

Hydraulic reservoir is mounted on an extension of the

bed at the rear to cut down heat transfer to machine

and to maintain machine alignment

Wheelhead ways are automatically lubricated with

filtered oil at each feed cycle

Coolant system has independent coolant tank which

can be rolled away from machine for easy cleanout

Automatic lubrication system for wheel spindle

has separate pump, reservoir and pressure switch
protection
