4. Who is KOYAMA? BARINDER was developed in 1972 for the purpose of labor-saving in the foundry. BARINDER has been loved and used by many foundry customers as a system specialized for qualified finishing of castings, in over 28 different countries in the world.

5. Problem of conventional manual work • Problem of conventional manual work for removing burrs and fins of casting • Human error (Uneven quality by workers) • Taking time for preparation • Numerous hazards

6. What is BARINDER? • BARINDER is a solution to the conventional manual finishing and de-burring work, realizing automation!! HARD ! DIRTY ! DANGEROUS !

7. Problem of conventional manual work • Hand grinders ■Double-end grinder ■Grinder for large size work ■Grinder for small and medium size work Holding a heavy-weight grinder or work with the same posture is a heavy work, that obstructs high dimensional accuracy finishing.

8. Problem of conventional manual work Hazards • Safety issues ・Vibration (White finger disease) ・Noise ・Dust flying ・Injury by accident ・Heavy work, back pain, etc. Vibration Noise, Dust Back pain

9. Solution by BARINDER • Introducing BARINDER will solve the aforementioned problems and contribute to the following advantages!! • Improved productivity • Improved grinding accuracy • Space saving, Energy saving • Improved working environment

10. Advantages by introducing BARINDER • Sophisticated and easy operation • Easy programming • Long-life tools • Reduced running cost and dust generation by diamond tool • Easy fixture change and shortened preparation time • Quick correspondence to frequent work change • Can handle complicated profile • Small installation space • Excellent durability and maintainability • Plural-unit operation by a single operator • Improved productivity and quality by high-efficient and high-speed process

11. Advantages by introducing BARINDER • Sustained quality and dimensional accuracy of finish ■ Manual finishing work Non-uniform finish ■Automatic finishing by BARINDER Uniform finish

12. Composition of BARINDER • Main Unit Operation panel Front shutter Hood Chip and dust collection box

13. Composition of BARINDER Work clamp bar Small wheel Work Main wheel Work set fixture

14. Break bracket VTR

15. Composition of BARINDER • Unique horizontal & vertical work moving mechanism • NACR Control System has achieved fast moving of work, by horizontal rotation table, horizontal joint arm and vertical lift mechanism.

16. 【NACR Control System】 • NACR control is a system that converts the motion of the mechanism by polar coordinate to the rectangular coordinate. • NACR is KOYAMA’s original control software achieving easy operation similar to NC control, utilizing robot arm mechanism. X-axis A-axis Y-axis Z-axis

17. 【Automatic Load control system】 Grinding speed (work feed speed) is controlled to vary so that the load to the work is sustained same. • Advantages: • 1. Improved efficiency of tool drive motor (Reduced electricity consumption) • 2. Shortened grinding time • 3. Improved life of tool and machine (Reduced heat generation from tool) • 4. Reduced tool motor size (due to equalized grinding load) • 5. Improved grinding accuracy

18. Composition of BARINDERPallet changer type Hood • Main unit Operation panel Change rotation door Safety door

19. Composition of BARINDERPallet changer type Work clamp bar Small wheel Main wheel Work Pallet Work set fixture

20. 【Work feed mechanism】Pallet changer type • 2-position Pallet changer or work load/unload system is available as an option, for more efficient work feed. • Pallet change is generally used for two same fixture, however, it can also be used for two different fixtures to process different works alternately or randomly.

21. 【Work feed mechanism】Pallet changer type Advantage of work feed system 1. Work set or change is possible while the work is processed in the machine. (This system is particularly effective for medium and large size work.) 2. Automated line can be built by adding work transfer system after processing.

22. 【Tool: Wheel】 • Grinding tool: Diamond Wheel • Main wheel • Small-wheel Complex shape can be processed by utilizing two different tools.

23. 【Tool: Wheel】 • Features Diamond grains are bonded to various shape of iron wheel. Tool diameter does not change in large volume. Tool itself has high durability, achieving high-accurate and high-speed finishing. Φ405xT10x Φ80 Φ405xT4x Φ80 Φ355xT12x Φ80

24. 【Tool: Wheel】 • Small wheel High-speed (Max. 15,000 rpm) small tool is effectively used to clean narrow and small area where main wheel cannot reach. Various size of tool is available according to the shape of work.

25. Programming • Direct teaching using the work is the base of the programming. • There are 3 different methods in Direct teaching. Each method has unique features. Combination of each method is also available. 1. Hand Teaching (available in F300 & F400 Series Clamp unit Operator hold the work, which is held by the clamp unit and sits on the fixture mounted on A-axis table. Then the operator let the teaching point touch the grinding tool. Coordinate value is input on the touch panel. Main wheel Fixture

26. Programming 2. Manual pulse generator teachingManual pulse generator attached to the operation panel has selector switch of axis and job-dial. Work table (fixture) moves by the number of pulse by jog-dial on each axis. Operator moves the work by this dial operation and let the teaching point touch the tool so that coordinate value can be input by 1-push operation. This method is effective for more accurate position teaching.

27. Programming 3. JOG Teaching • Operator moves the work by operating by the switches on the touch panel. Coordinate value where work touches the tool will be written to the program. (Equipped as standard in all models) • In this mode, only minimum drive force for teaching is required. Teaching can be performed under safe circumstance. (Safe operation control system) ; (Available in F300 and F400 series)

28. Programming • Part of the grinding program can be modified by block. ・ Modification or correction of grinding program is easy by only input of moving direction (front/back, left/right, up/down, rotation) and value of movement. ・ Correction of data in the specified block can be done by pointing the range. (NACR control system)

29. Networking of BARINDER • 98 (99 for changer type) grinding programs can be stored in BARINDER. • If number of programs exceed above, BARINDER can communicate with outer devices such as NACR device, CNC equipment or PC, using NACR Network System via. Hub by Ethernet. • Function(1) Upload and download of NACR and CNC programs(2) Input/output of CNC parameters(3) Directory display in PC(4) Printout of grinding program
