Questions about an order, a machine or a build? You are talking to the guy who made it.

Four detailed starting points

Wiring, returns, parts and belt speed. Each one is written out in full, so you are not waiting on an email to get moving.

At the grinder

Belt changes and tracking

Two adjustments you make on every Torus, shown on the parts themselves: the ratchet that holds belt tension and the knob that sets tracking.

Release, swap, ratchet

A belt change is release, swap, ratchet, and the spring pawl and toothed cam hold the tension afterward, not a spring that fades.

  1. Release
  2. Swap
  3. Ratchet
  • stainless tension arm
  • spring pawl
  • toothed cam
  • tracking wheel

Every Torus grinder ships with machined spacing built in and a 304 stainless ratchet tensioner, so a belt change is release, swap, ratchet.

A spring tensioner fades; a ratchet does not.

Tracking with one knob

Tracking is one small, repeatable adjustment at the 4-lobe knob on the machined billet-aluminum head, the same head on every Torus.

Tracks with one knob

  • 4-lobe tracking knob
  • machined billet-aluminum dual-axis tracking head
  • wide aluminum idler wheel

The stainless ratchet tensioner sets belt pressure in one motion, and tracking takes one small, repeatable adjustment.

The dual-axis tracking head end on, with the belt on the wide idler wheel.

FAQ

Questions about orders and machines

Shipping times, returns, warranty, drive wheels and custom work — answered once, properly.

How long will it take for my order to ship?

Most orders ship in seven to ten business days from time of order. A more detailed delivery estimate will be given upon ordering your grinder. Every grinder is built to order; accessories, backlog or custom work can add time. You get a tracking number the day it ships.

Can I return my item if something’s wrong with it?

Email me first and we will work through it together. If it is a workmanship problem, I will work with you to remedy it. Returns are approved case by case within two weeks of arrival. Because every machine is built to order, approved returns carry a 25% restocking fee, you cover insured return shipping for the full purchase price, and original shipping is not refunded.

What’s covered under the warranty?

I warranty the non-wear parts of the grinder against defects in materials and workmanship under normal use. Belts, wheels and other wear items are not covered, and neither is damage from misuse or modification. Motors and VFDs carry their manufacturer’s warranty and I will help you through a claim. Email me and I will review the issue under the warranty policy.

What’s the difference between a 4-inch and 7-inch drive wheel?

The 4-inch wheel runs the belt slower with more torque, which gives you control for sharpening, finishing and tough steels, and it is what ships on every Torus. The 7-inch spins the belt about 75% faster for quick stock removal on big work. It depends on what you grind most.

Do you offer custom modifications or products?

Yes. Tooling arms without holes, a custom powder coat color on the Nova, or a specific setup for your shop: email me what you need and I will tell you what it costs and how long it takes. Most of it is a small change in my program.

Can I track my order after it ships?

Yes. The day your order leaves Sterling, Illinois you get an email with the tracking number, so you can watch it all the way to your door.

Do you ship internationally?

Yes. Grinders are heavy, so international shipping is quoted per order. Email me your address and what you want to order and I will send you a shipping rate and any details specific to your country.

What happens if my item arrives damaged?

Contact me when the order arrives and send photos of the box, the packing and the damage. I will review the shipment and the available next steps with you.

What payment methods do you accept?

Card (Visa, Mastercard, American Express, Discover), Apple Pay, Google Pay, Link, Cash App and Amazon Pay, or pay over time with Affirm, Klarna or Afterpay — all at checkout, over Stripe. Your card number never touches this site. If you need to arrange payment another way, call or text me.

How can I reach you if I have more questions?

Email me at rich.linville@toruscnc.com, or call or text 1-779-372-0262, Monday through Friday, 9:00am to 4:00pm Central. You will reach the person who built your grinder.

    Just received my 2 x 72 M90 belt grinder from Rich at Torus CNC. I've been using a Jet 2 x 42 belt grinder for several years. The Torus M90 is a game changer and the quality is first rate. Rich did a great job keeping me informed and shipped the grinder quicker than I expected. I highly recommend this grinder.
