INTRODUCTION

TP-4 is a smart tech high precision CNC cylindrical pinch/peel grinder with two grinding wheels operating simultaneously for grinding cylindrical materials of cutting tools and form punches. This model is used after doing centerless grinding and before doing the pre-process work on 5-axix tool grinder. It has applied to various industries, mainly used in high-precision tool industry, mold industry, and electronic and medical parts industry.

TP-4 Can meet all your application needs for grinding carbide and endmill, drill and form blanks.

FEATURES

Machine structure

The bed of the machine is designed as box-type structure, equipped with double grinding wheel spindles (X & U-axis); Z & W-axis adopt high-precision parallel axis structure, which shows the capacity of grinding with roughing pass numerously as well as roughing and finishing in a single pass.

CAE analysis

Reliable simulation parameters of the mechanical structure of TP-4 is obtained through the finite element analysis on mechanical modal value simulation. Outstanding frequency response function is acquired by testing on spectrum analyzer and accelerometer, tapping on important mechanical components, and simulating overall modals. This fuction further imports into the modal analysis software, ME'Scope, to establish a modal shape for doing comparison between the results of the modal value simulation and experimental modal analysis. By having these processes, it enables us to bring the users with the best value for quality, reliability, and performance.

Automatic Loading / Unloading System

A 3-axes automatic loading/unloading system is offered as a part of the standard machine and it allows unattended and high-speed production. During production, it can carry up to 2 loading trays at the same time with a capacity of up to 1'300 tools.

Controller and Software

TP Smart software is main core of TP-4 precision cylindrical pinch/peel grinder. 34 built-in quick setup modules are achieved to be used for grinding milling cutters, drills, punches, and all other cylindrical or stepped applications. CAD mode of the software allows operators to create any type of tool profile in just few settings. With the import of DXF format, it is possible for the users to grind special shaped tools, especially in the profile design of the formed punches.
In CAM function, two modes are offered respectively to the operators for choosing to do grinding or regrinding. Triple approaches can be selected for the use of grinding wheels, including simultaneous grinding of both wheels, roughing grinding, and finishing grinding. Operators just need to sequentially input workhead speed, wheel speed, wheel distance, finish depth, and safety distance, then simulation of the grinding path will be generated successfully. The NC program can be carried out and transferred to the controller after confirming simulated path. This can provide TOPWORK machine users with a completely perfect using experiences and enable them to conduct an inestimable volume of applications with the machine.
